Description

TECHNICAL FIELD

[0001] The present disclosure relates to a laser alignment system for a light fixture mounting bracket. More particularly, the present disclosure is directed to a laser alignment system that includes an alignment bracket and a laser alignment tool, where the mounting bracket includes a target that is aligned with a laser beam generated by the laser alignment tool. BACKGROUND

[0002] Aircraft are equipped with landing lights that are used to illuminate the terrain and runway ahead during takeoff and landing. Aircraft can also include runway taxi lights that are typically mounted on the leading edge of the wing. The runway taxi lights are used to illuminate the high speed runway exit as the aircraft decelerates during landing.

[0003] The landing lights and runway taxi lights require very precise installation accuracy. Thus, if the mounting angle of the bracket holding the landing lights is even relatively slightly off, this can result in inadequate illumination in the area in front of the aircraft. During aircraft assembly, laser tools are used to align the brackets holding the landing and runway taxi lights.

[0004] The alignment process becomes particularly time consuming and labor intensive when performed with an aircraft in flight rather than at a manufacturing plant. This is because the brackets holding the landing lights are above the ground and can only be reached by elevating the workers into the air using machinery such as an aerial lift. For example, one type of aircraft requires four people working for approximately sixteen hours to align the landing and runway taxi lights. SUMMARY

[0005] According to several aspects, a laser alignment system for adjusting a mounting bracket of a light fixture is disclosed. The laser alignment system includes an alignment bracket that includes a body portion defining one or more target features and a plurality of index features. The one or more target features include a target configured to be aligned with a laser beam, and the plurality of index features are configured to position the alignment bracket along a surface. The laser alignment system also includes a laser alignment tool that includes a base, a mount, and a laser device. The mount holds the laser device in place, and the laser device is configured to emit a laser beam, and the base of the laser alignment tool is shaped to fit within the mounting bracket of the light fixture, and the laser device directs the laser beam toward a corresponding one of the target features of the alignment bracket.

[0006] In another aspect, a laser alignment system is disclosed for aligning an external aircraft light positioned along a leading edge of a wing of an aircraft. The laser alignment system includes an alignment bracket including a body portion defining one or more target features, a plurality of index features, and an outer periphery. The one or more target features include a target configured to align with a laser beam, and the plurality of index features are configured to position the alignment bracket along the leading edge of the wing of the aircraft, and the outer periphery of the alignment bracket is shaped to fit around an opening of an external landing light positioned along the leading edge of the wing. The laser alignment system further includes a laser alignment tool including a base, a mount, and a laser device. The mount holds the laser device in place, and the laser device is configured to emit a laser beam, and the base of the laser alignment tool is shaped to fit within a mounting bracket of a light fixture positioned along the leading edge of the wing, and the laser device directs the laser beam toward a corresponding one of the target features of the alignment bracket.

[0007] In yet another aspect, a method is disclosed for aligning a mounting bracket corresponding to a light fixture positioned along a leading edge of a wing of an aircraft. The method includes placing a base of a laser alignment tool within a mounting bracket corresponding to the light fixture, wherein the laser alignment tool includes a laser device configured to emit a laser beam. The method includes positioning an alignment bracket in place around an opening positioned along the leading edge of the wing of the aircraft. The method further includes directing the laser beam emitted by the laser device toward a corresponding target feature of the alignment bracket. The corresponding target feature of the alignment bracket includes a target configured to align with the laser beam emitted from the laser device when the mounting bracket is in a correct installation position. Finally, the method includes adjusting the mounting bracket holding the laser alignment tool in place until the laser beam emitted by the laser device aligns with the target of the corresponding target feature of the alignment bracket.

[0020] The present disclosure is directed to a laser alignment system for adjusting mounting brackets of luminaires. The laser alignment system includes an alignment bracket having a body portion defining one or more target features and a plurality of index features, wherein each of the target features includes a target configured to align with a laser beam. The index features are configured to position the alignment bracket along a surface. The laser alignment system further includes a laser alignment tool having a base, a mount, and a laser device. The mount of the laser alignment tool holds the laser device in place, and the laser device is configured to emit a laser beam. The base of the laser alignment tool is shaped to fit within a mounting bracket of a luminaire, and the laser device directs the laser beam toward a corresponding one of the target features of the alignment bracket.

[0021] A person adjusts the mounting brackets of the light fixtures until the laser beam is aligned with a target defined by a pair of crosshairs that are part of a corresponding one of the target features of the alignment bracket. The present disclosure also includes a method for aligning the mounting brackets using the disclosed laser alignment system. It should be appreciated that the alignment bracket of the disclosed laser alignment system is relatively lightweight and compact in size, and is therefore portable. In other words, a person is able to carry the alignment bracket. The laser alignment tool is also relatively lightweight and is powered by a battery. Thus, the laser alignment tool is also portable.

[0022] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

[0023] Reference Figure 1 is shown. The aircraft 10 includes a fuselage 12 and a pair of wings 14. A nose 20 is located at a forward end 16 of the aircraft 10, and a tail 22 is located at an aft end 18 of the aircraft 10. The tail 22 of the aircraft 10 includes a vertical stabilizer 24 and a horizontal stabilizer 26. The wings 14 of the aircraft 10 extend outwardly from opposite sides 30 of the fuselage 12. Each wing 14 of the aircraft 10 defines a leading edge 32, a trailing edge 34, and a wing tip 36. The aircraft 10 also includes a pair of runway taxi lights 38 (one of which is shown in Figure 2 ) and a pair of landing lights 40 (one of which is also shown in Figure 2 ), with one of the runway taxi lights 38 and one of the landing lights 40 being mounted on the leading edge 32 of each wing 14. As explained below, a laser alignment system 42 Figure 3 is provided to align the external aircraft lighting lights (i.e., the runway taxi lights 38 and the landing lights 40) provided along one of the wings 14 of the aircraft 10.

[0024] Referring generally to Figures 1-3 , the runway taxi lights 38 and the landing lights 40 emit very bright light, and thus are not illuminated when a person, such as a pilot and a maintenance crew member, is in close proximity. This is to avoid exposing the person's eyes to the bright light emitted by the lights 38, 40. For example, in one embodiment, the landing lights 40 emit light having a rating of about 4,500 lumens. As a result, the lights 38, 40 are not illuminated when a person is aligning the lights 38, 40. Instead, the laser alignment system 42 is used to adjust the position of the respective mounting brackets 70, 72 Figure 2 corresponding to the lights 38, 40.

[0025] Although the present disclosure describes a laser alignment system 42 for adjusting the position of exterior aircraft lighting, it should be understood that the present disclosure is not limited to aircraft. Alternatively, the laser alignment system 42 can be used to align any light fixture that emits high intensity light and thus is not illuminated when a person is in close proximity in order to protect their eyes.

[0026] Reference is now made to Figure 3 , the disclosed laser alignment system 42 includes an alignment bracket 44 and a laser alignment tool 46. Figure 3 The alignment bracket 44 is shown positioned about an opening 52 disposed along a leading edge 32 of one of the wings 14. Figure 3 The landing light 40 and the runway taxi light 38 are also shown removed from the aircraft 10, with the laser alignment tool 46 held in place by a mounting bracket 70 corresponding to the runway taxi light 38. The alignment bracket 44 includes a plurality of index features 48. Each index feature 48 of the alignment bracket 44 is configured to align with a mounting feature 50 disposed about the opening 52 positioned along the leading edge 32 of the wing 14. The lights 38, 40 are positioned within the opening 52 in the wing 14. In the embodiment as shown, the mounting features 50 are fasteners, however other devices can also be used. The index features 48 are configured to position the alignment bracket 44 along a surface such as the leading edge 32 of the wing 14. As explained below, the alignment bracket 44 also includes one or more target features 54, with each target feature 54 corresponding to a unique mounting bracket for a light fixture disposed along the leading edge 32 of the aircraft 10. Figure 1 ) disposed along the leading edge 32 of the aircraft 10.

[0027] Reference is now made to Figure 3 、 Figure 5 and Figure 6 The laser alignment tool 46 includes a base 56, a housing 58, and a laser device 60. The housing 58 of the laser alignment tool 46 secures the laser device 60 in place. The laser device 60 is configured to emit a laser beam 62 that is directed toward a corresponding one of the target features 54 of the alignment bracket 44. In one embodiment, the base 56 of the laser alignment tool 46 is shaped to fit within the mounting bracket 70 for the runway taxi light 38, and the laser device 60 directs the laser beam 62 toward a corresponding one of the target features 54 of the alignment bracket 44.

[0028] Figure 4One of the runway taxi lights 38 and one of the landing lights 40 are shown mounted within corresponding openings 63, 64 provided along the metal panel 66 of the aircraft 10. The runway taxi light 38 includes a light fixture 68 held in place by a mounting bracket 70. Similarly, the landing light 40 also includes a light fixture 74 held in place by a mounting bracket 72 within the opening 64 of the metal panel 66. The mounting bracket 70 corresponds to the runway taxi light 38 and includes a mounting ring 80 and a plurality of mounting pins 82. The mounting ring 80 of the mounting bracket 70 is shaped to hold a housing 84 of the light fixture 68 of the runway taxi light 38. Similarly, the mounting bracket 72 corresponding to the landing light 40 also includes a mounting ring 90 and a plurality of mounting pins 92, wherein the mounting ring 90 is shaped to hold a housing 94 of the light fixture 74 of the landing light 40.

[0029] The light fixture 68 of the runway taxi light 38 is held in a predetermined position by the mounting bracket 70, and the light fixture 74 of the landing light 40 is also held in a corresponding predetermined position by the mounting bracket 72. It is recognized that the light fixture 68 corresponding to the runway taxi light 38 is oriented at a taxi angle Referring to Figure 1 and Figure 4 , the taxi angle As can be seen in Figure 1 , the right runway taxi light (not visible in Figure 1 ) is angled toward the right side R of the aircraft 10, and the left runway taxi light (also not visible in Figure 1 ) is angled toward the left side L of the aircraft 10. Each of the runway taxi lights 38 is oriented at a taxi angle to illuminate the taxiway or obstacles located on the left and right sides of the aircraft 10.

[0030] Referring to Figure 2 and Figure 4 , a plurality of apertures 98 are provided around the mounting ring 80 of the mounting bracket 70, and a plurality of apertures 100 are formed around the mounting ring 90 of the mounting bracket 72. The position of the light fixture 68 is adjusted by rotating the mounting pins 82 clockwise or counterclockwise within the corresponding apertures 98 of the mounting ring 80. Similarly, the position of the light fixture 74 is also adjusted by rotating the corresponding mounting pins 92 clockwise or counterclockwise within the corresponding apertures 100 of the mounting ring 90. In the exemplary embodiment shown, the mounting brackets 70, 72 each include three mounting pins 82, 92 equally spaced from one another.

[0031] Figure 5 and Figure 6 are perspective views of the laser alignment tool 46. In the embodiment shown, the base 56 of the laser alignment tool 46 is circular to correspond to the mounting bracket 70 used to hold the light fixture 68 in place Figure 4) corresponds. The base 58 of the laser alignment tool 46 is disposed along the upper surface 102 of the base 56 and projects outwardly relative to the upper surface 102 of the base 56. The base 58 is oriented perpendicularly relative to the upper surface 102 of the base 56. Thus, as seen in Figure 3 、 Figure 5 and Figure 6 , the laser beam 62 emitted by the laser device 60 is oriented perpendicularly relative to the upper surface 102 of the base 56 of the laser alignment tool 46.

[0032] In one embodiment, the laser device 60 includes an elongated body 106. In the example shown in Figure 5 and Figure 6 , the body 106 of the laser device 60 includes a cylindrical profile, however, the body 106 of the laser device 60 can include other profiles. The body 106 of the laser device 60 is held in place by an alignment feature 110 that is part of the base 58. As seen in Figure 6 , the alignment feature 110 includes an aperture 112 shaped to receive a portion of the body 106 of the laser device 60. In an embodiment, the laser device 60 of the laser alignment tool 46 includes a battery (not shown) for powering the laser device 60. As a result, the laser alignment tool 46 does not require an extension cord and is portable.

[0033] Referring now to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the base 56 of the laser alignment tool 46 is shaped to correspond with the mounting ring 80 of the mounting bracket 70 corresponding to the runway taxi light 38 (see Figure 4 ). Referring specifically to Figure 3 , during the alignment process, the base 56 of the laser alignment tool 46 is placed within the mounting bracket 70 instead of the light fixture 68. The laser beam 62 is directed toward a corresponding one of the target features 54 of the alignment bracket 44. Specifically, as explained below, each target feature 54 of the alignment bracket 44 corresponds to a unique mounting bracket that is part of the aircraft 10. A person adjusts the mounting pin 82 disposed about the mounting ring 80 of the mounting bracket 70 until the laser beam 62 is aligned with a target 180 defined by a pair of crosshairs 182 that are part of the corresponding one of the target features 54 (shown in Figure 8A and Figure 8B and described in greater detail below).

[0034] Figure 7 An extension bracket 128 for the laser alignment tool 46 is shown. Referring to Figure 6 and Figure 7, the extension bracket 128 defines an inner annular surface 130 that corresponds to an outer periphery 132 of the base 56 of the laser alignment tool 46, and an outer annular surface 134 that corresponds to the mounting ring 90 of the mounting bracket 72 corresponding to the runway taxi light 38 Figure 3 It should be appreciated that the base 56 of the laser alignment tool 46 is only shaped to correspond to the mounting ring 80 of the mounting bracket 70 corresponding to the runway taxi light 38. However, as seen in Figure 2 , the mounting ring 90 of the mounting bracket 70 includes a diameter D2 that is greater than the diameter D1 of the mounting ring 90 of the mounting bracket 72. Accordingly, the extension bracket 128 is removably attached about the outer periphery 132 of the base 56 of the laser alignment tool 46 first, and then the base 56 is placed within the mounting bracket 72 corresponding to the runway taxi light 38.

[0035] Figure 8A and Figure 8B are perspective views of the alignment bracket 44. Specifically, Figure 8A shows an outer surface 136 of the wall 138 of the alignment bracket 44, and Figure 8B shows an inner surface 140 of the wall 138 of the alignment bracket 44. In the non-limiting embodiment shown in Figure 8A and Figure 8B , the alignment bracket 44 includes three index features 48A, 48B, 48C and three target features 54A, 54B, 54C, however, it should be appreciated that these figures are merely exemplary in nature. The alignment bracket 44 includes a body portion 142 that defines the index features 48A, 48B, 48C and the target features 54A, 54B, 54C.

[0036] In one non-limiting embodiment, the body portion 142 of the alignment bracket 44 is constructed by an additive manufacturing method, however, it should be appreciated that other manufacturing methods can also be used. In embodiments, the alignment bracket 44 is constructed from a relatively lightweight material, such as, for example, a polymer. Accordingly, the alignment bracket 44 is portable and can be easily held and carried by a single person. For example, in the embodiment shown in Figure 3 , the person can use his or her hands H to hold the alignment bracket 44 in place against the opening 52 disposed along the leading edge 32 of the wing 14.

[0037] The body portion 142 of the alignment bracket 44 defines an outer periphery 144. The plurality of index features 48A, 48B, 48C are each disposed along the outer periphery 144 of the alignment bracket 44. Specifically, the outer periphery 144 of the body portion 142 of the alignment bracket 44 includes two linear segments 152, 154 that are each disposed on opposite ends 158 of the alignment bracket 44. The outer periphery 144 of the alignment bracket 44 also includes two undulating segments 160, 162 that are disposed on opposite sides 164 of the alignment bracket 44.

[0038] Referring to Figure 3 , Figure 8A and Figure 8B , the contoured sections 160, 162 disposed about the outer periphery 144 of the body portion 142 of the alignment bracket 44 are shaped to correspond with the openings 52 disposed about the light fixtures 68, 74. In the embodiment shown in Figure 3 , the openings 52 are disposed along the leading edge 32 of the aircraft 10, the mounting features 50 are disposed about the openings 52, and the two contoured sections 160, 162 of the alignment bracket 44 are each shaped to correspond with the elliptical openings 52 disposed along the wing 14 of the aircraft 10. However, it should be appreciated that these figures are merely exemplary in nature, and that the contoured sections 160, 162 of the alignment bracket 44 can include any type of shape. That is, the two contoured sections 160, 162 are shaped to correspond with the arrangement of the mounting features 50 disposed along the surface to which the alignment bracket 44 is mounted (i.e., the leading edge 32 of the wing 14).

[0039] In the non-limiting embodiment shown in Figure 3 , a person holds the alignment bracket 44 in place against the openings 52 disposed along the leading edge 32 of the wing 14. Specifically, Figure 3 a person is shown using his or her hands H to hold the alignment bracket 44 in place. However, in an alternative approach, a clamping device or other securing device (not shown) can be used to hold the alignment bracket 44 in place. However, it should be appreciated that the person's hands H are free if a clamping device is used. Thus, only one person is needed to align the mounting brackets 70, 72 if a clamping device is used.

[0040] Referring to Figure 3 , Figure 8A and Figure 8B , the index features 48A, 48B, 48C each define a corresponding aperture 164A, 164B, 164C, wherein the apertures 164A, 164B, 164C are each shaped to receive one of the mounting features 50 disposed about the openings 52 of the leading edge 32 of the wing 14. Specifically, the index feature 48A is disposed along the contoured section 160, the index feature 48B is disposed along the contoured section 162, and the index feature 48C is disposed along the linear section 154 of the alignment bracket 44.

[0041] It should be appreciated that the outer periphery 144 of the alignment bracket 44 is shaped to correspond with the openings 52 disposed about the external landing lights (i.e., the runway taxi lights 38 and the landing lights 40) along either of the wing 14 on the left side L or the wing 14 on the right side of the aircraft 10. In the example shown in Figure 3 , the outer periphery 144 of the alignment bracket 44 is shaped to correspond with the openings 52 disposed along the leading edge 32 of the wing 14 located on the left side L of the aircraft 10.Figure 1 The opening 52 includes an elliptical profile having a tapered end 158 oriented toward the left side L of the aircraft 10 (see Figure 2 ).

[0042] A separate opening 52 is also provided along the leading edge 32 of the wing 14 that is also provided along the right side R of the aircraft 10 Figure 1 ). However, the tapered end 158 of the opening 52 provided along the right side R of the aircraft 10 is oriented toward the right side R of the aircraft 10. In other words, the openings 52 provided on the left side L and the right side R of the aircraft 10 are mirror images of one another. As a result, separate alignment brackets 44 are provided for the exterior lights on the wing 14 provided on the right side R of the aircraft 10 and the exterior lights on the wing 14 provided on the left side L of the aircraft 10.

[0043] Referring to Figure 8A and Figure 8B , in the illustrated embodiment, the length of the linear section 152 is longer when compared to the linear section 154 of the alignment bracket 44. Figure 8C The alignment bracket 44 is shown as viewed along the linear section 152 of the alignment bracket 44. The body portion 142 of the alignment bracket 44 includes a contoured profile 168. In the non-limiting embodiment shown in Figure 8C , the contoured profile 168 is shaped to correspond to a portion of a cylinder 166 (shown in dashed lines) as viewed along the linear section 152 (which is along the outer periphery 144 of the alignment bracket 44). However, it should be appreciated that these figures are exemplary in nature only, and that the contoured profile 168 of the body portion 142 of the alignment bracket 44 is not limited to a cylindrical shape. The body portion 142 of the alignment bracket 44 includes any contoured profile required to allow a user to access and adjust the alignment bracket 44 during the installation process.

[0044] Target features 54A, 54B, 54C defined by the body portion 142 of the alignment bracket 44 will now be described. Although the figures show three target features 54A, 54B, 54C, it should be appreciated that the alignment bracket 44 includes one or more target features 54. In the illustrated embodiment, Figures 8A-8C , the alignment bracket 44 includes a plurality of target features 54A, 54B, 54C, wherein each target feature 54A, 54B, 54C corresponds to a unique mounting bracket 70, 72 Figure 4 ), and wherein each unique mounting bracket 70, 72 corresponds to a unique light fixture 68, 74. For example, in the illustrated embodiment, the target feature 54A corresponds to the mounting bracket 72 of the light fixture 68 that holds the runway taxi light 38 Figure 2 ), the target feature 54B corresponds to the mounting bracket 72 that holds the light fixture 74 for the runway taxi light 38, and the target feature 54C corresponds to the mounting bracket 72 that holds the light fixture 74 for the runway taxi light 38 along the left side L of the aircraft 10.Figure 1 The other runway taxi lights are set on the wing 14 of the aircraft.

[0045] Target features 54A, 54B, and 54C are each disposed along the wall 138 of the alignment bracket 44 and include a raised profile 170. In the illustrated exemplary embodiment, the raised profile 170 of each target feature 54A, 54B, and 54C defines a hollow cylindrical notch along the wall 138 of the alignment bracket 44. However, the raised profile 170 of the target features 54A, 54B, and 54C is not limited to a cylindrical notch and may include other configurations. (See reference...) Figure 8B Each target feature 54A, 54B, 54C has a raised profile 170 defining a circular sidewall 172 and an end face 174, wherein the end face 174 of each target feature 54A, 54B, 54C is disposed along the inner surface 140 of the wall 138. In one embodiment, the end face 174 of each target feature 54A, 54B, 54C includes a pair of crosshairs 182 that intersect each other to define a target 180. (Reference) Figure 3 , Figure 8A and Figure 8B The laser beam 62 emitted by the laser device 60 is configured to be aligned with the target 180 corresponding to the target features 54A, 54B, and 54C.

[0046] although Figure 8B A pair of intersecting crosshairs 182 are shown, but in another embodiment, the crosshairs 182 may be omitted. Instead, markings such as bullseyes may be used to indicate the position of the target 180.

[0047] Target 180 of each target feature 54A, 54B, 54C corresponds to the correct mounting position of a corresponding mounting bracket 70, 72 for each luminaire 68, 74. When the mounting brackets 70, 72 are positioned correctly, the luminaires 68, 74 direct light towards a predetermined area surrounding the aircraft 10. For example, when in conjunction with runway taxi lights 38 ( Figure 4 When the corresponding luminaire 68 is in the installation position, the light emitted by luminaire 68 travels along the turnoff angle. Guided.

[0048] Figure 9 This is an exemplary process flowchart illustrating the alignment with the aircraft 10 ( Figure 1 The corresponding luminaires 68 and 74 are installed on the leading edge 32 of the ) Figure 4 The mounting method 200 corresponds to one of the mounting brackets 70 and 72. (Generally refer to...) Figures 1-9Method 200 begins at frame 202. It should be understood that frame 202 is optional and is completed before placing the laser alignment tool 46 within one of the mounting brackets 70, 72. In frame 202, the extension bracket 128 ( Figure 7 ) Surrounding the laser alignment tool 46 ( Figure 6 The outer periphery 132 of the base 56 is removably attached. As described above, the base 56 of the laser alignment tool 46 is only shaped to correspond to the mounting ring 80 of the mounting bracket 70, which corresponds to the luminaire 68 for the runway taxi light 38. Therefore, if the mounting bracket 72 corresponding to the landing light 40 is aligned, the bracket 128 needs to be extended. Then, method 200 can proceed to frame 204.

[0049] In frame 204, the alignment bracket 44 is aligned via index features 48A, 48B, and 48C. Figures 8A-8B An opening 52, provided around the leading edge 32 of one of the plurality of wings 14 along the aircraft 10, is positioned in place, wherein each index feature 48A, 48B, 48C of the alignment bracket 44 is configured to align with one of the mounting features 50 provided around the opening 52. Method 200 can then proceed to block 206.

[0050] In frame 206, alignment bracket 44 is secured around an opening 52 provided around the leading edge 32 of the wing 14 of the aircraft 10. Referring to frames 206A and 206B, alignment bracket 44 is secured using one of two methods. For example, in frame 206A, alignment bracket 44 is manually secured in place by a person. Figure 3 In the illustrated embodiment, a person holds the alignment bracket 44 in place using his or her hand H. In block 206B, a clamping device or other securing device (not shown) secures the alignment bracket 44 in place. Method 200 can then proceed to block 208.

[0054] Referring generally to the accompanying drawings, the disclosed laser alignment system offers various technical effects and benefits. In particular, the alignment bracket of the laser alignment system is lightweight, portable, and easily operated by a single person. Therefore, it may only require one person to align the mounting bracket corresponding to the external aircraft light. In contrast, conventional alignment systems typically require multiple people to align the mounting bracket of the external lighting on the aircraft. Furthermore, the disclosed alignment bracket is portable and directly mounted to the aircraft. Conversely, conventional systems may require a tripod that includes the target, which rests on the ground.

[0055] It should be recognized that the disclosed laser alignment system can be particularly advantageous when used in aftermarket applications. This is because both the alignment bracket and the laser alignment tool are portable. It should be understood that the mounting brackets for the landing lights and runway taxi lights are located above the ground and can only be reached by lifting personnel into the air using machinery such as an aerial lift. As a result, some conventional systems may require multiple people working approximately sixteen hours to align the landing lights and runway taxi lights. However, the disclosed laser alignment system can require only one person and can align the landing lights and taxi lights in at most three hours.
