Technical Field

[0001] The invention belongs to the field of aviation technology and relates to a method and a device for prompting a manned transport aircraft when it approaches or deviates from a preset target altitude during flight. Background Art

[0002] When pilots are flying an aircraft, they must strictly follow the target altitude given by the ground control tower.

[0003] The pilot sets the target altitude of the aircraft through the flight control panel. When the aircraft approaches the target altitude, the pilot should be prompted by sound or display that the aircraft is approaching the target altitude; when the aircraft deviates from the target altitude, the pilot should be prompted by sound or display that the aircraft is deviating from the target altitude. Summary of the invention

[0004] The present invention provides a method and device for prompting an aircraft approaching or deviating from a target altitude, which provides a prompting time and a prompting method for approaching or deviating from a target altitude from two aspects: approaching or deviating from a target altitude from above the target altitude and approaching or deviating from a target altitude from below the target altitude, so that the pilot can more accurately obtain the relationship between the aircraft altitude and the target altitude during flight, thereby improving the reliability and safety of the flight.

[0005] A first aspect of the present invention provides a method for prompting an aircraft approaching or deviating from a target altitude, comprising:

[0006] S1. Obtain the current altitude deviation of the aircraft at the current moment, where the altitude deviation is the absolute value of the difference between the flight altitude and the target altitude;

[0007] S2, determine whether the current height deviation is greater than the stored height deviation at the previous moment, if so, proceed to S3; if not, proceed to S6;

[0008] S3, determine whether the stored altitude deviation is greater than 1100ft, if so, proceed to S9; if not, proceed to S4;

[0009] S4, determine whether the current altitude deviation is greater than 1100ft, if so, set the approach target altitude prompt state to be valid and enter S9; if not, enter S5;

[0010] S5, determining whether the stored height deviation is less than the first preset deviation height, and the current height deviation is greater than the first preset deviation height, if so, setting the deviation from the target height prompt state to be invalid, and entering S9; if not, entering S9;

[0011] S6, determine whether the current altitude deviation is greater than 1000ft, if so, proceed to S9; if not, proceed to S7;

[0012] S7, determine whether the stored altitude deviation is greater than 1000ft, if not, proceed to S8; if yes, when the light is always on, turn off the light, and set the approach target altitude prompt state to be invalid, and proceed to S9; when the light is very bright, set the approach target altitude prompt state to be invalid, and proceed to S9;

[0013] S8, determining whether the stored altitude deviation is greater than the second preset deviation altitude, and the current altitude deviation is less than the second preset deviation altitude, if so, setting the deviation target altitude prompt state to be valid, and entering S9; if not, entering S9;

[0014] S9, update the stored height deviation according to the current height deviation, and return to S1;

[0015] When the target altitude approaching prompt status changes from valid to invalid, a first prompt tone is played once and a flashing light prompt is performed for a preset duration;

[0016] When the deviation from target altitude prompt status changes from valid to invalid, the second prompt tone is played once and the flashing light prompt is performed for a preset time. After the preset time, the light remains on.

[0017] Optionally, it also includes;

[0018] When the light remains on and an updated target altitude is received or the light is turned off manually, the steady reminder light will be turned off.

[0019] Optionally, the second preset deviation altitude is 100 or 900 ft.

[0020] Optionally, the second preset deviation altitude is 100 and 900 ft.

[0021] Optionally, the first prompt sound is used to indicate that the target altitude is approaching.

[0022] Optionally, the second prompt tone is used to indicate deviation from the target altitude.

[0023] Optionally, the first preset deviation altitude is 200 or 1000 ft.

[0024] Optionally, the first preset deviation altitude is 200 and 1000 ft.

[0025] A second aspect of the present invention provides a device for prompting an aircraft approaching or deviating from a target altitude, for executing the method as described in any one of the first aspects.

[0026] The present invention provides a prompting method and device for an aircraft approaching or deviating from a target altitude, which provides the timing of prompting sounds and lights when the aircraft approaches or deviates from the target altitude through the changing relationship between the altitude of the aircraft and the target altitude, so that the pilot can obtain the relationship between the altitude of the aircraft and the target altitude more accurately during flight, thereby improving the reliability and safety of the flight.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0031] like Figure 1-3 As shown, the present invention provides a method for prompting an aircraft approaching or deviating from a target altitude, comprising:

[0032] S1. Obtain the current altitude deviation of the aircraft at the current moment, where the altitude deviation is the absolute value of the difference between the flight altitude and the target altitude;

[0033] S2, determine whether the current height deviation is greater than the stored height deviation at the previous moment, if so, proceed to S3; if not, proceed to S6;

[0034] S3, determine whether the stored altitude deviation is greater than 1100ft, if so, proceed to S9; if not, proceed to S4;

[0035] S4, determine whether the current altitude deviation is greater than 1100ft, if so, set the approach target altitude prompt state to be valid and enter S9; if not, enter S5;

[0036] S5, determining whether the stored height deviation is less than the first preset deviation height, and the current height deviation is greater than the first preset deviation height, if so, setting the deviation from the target height prompt state to be invalid, and entering S9; if not, entering S9;

[0037] S6, determine whether the current altitude deviation is greater than 1000ft, if so, proceed to S9; if not, proceed to S7;

[0038] S7, determine whether the stored altitude deviation is greater than 1000ft, if not, proceed to S8; if yes, when the light is always on, turn off the light, and set the approach target altitude prompt state to be invalid, and proceed to S9; when the light is very bright, set the approach target altitude prompt state to be invalid, and proceed to S9;

[0039] S8, determining whether the stored altitude deviation is greater than the second preset deviation altitude, and the current altitude deviation is less than the second preset deviation altitude, if so, setting the deviation target altitude prompt state to be valid, and entering S9; if not, entering S9;

[0040] S9, update the stored height deviation according to the current height deviation, and return to S1;

[0041] When the target altitude approaching prompt status changes from valid to invalid, a first prompt tone is played once and a flashing light prompt is performed for a preset duration;

[0042] When the deviation from target altitude prompt status changes from valid to invalid, the second prompt tone is played once and the flashing light prompt is performed for a preset time. After the preset time, the light remains on.

[0043] Exemplarily, when the light remains on and an updated target altitude is received or the light is manually turned off, the steady reminder light is turned off.

[0044] Exemplarily, the method for prompting a manned transport aircraft approaching or deviating from a target altitude provided by the present invention is specifically as follows:

[0045] When the aircraft approaches the target altitude from above or below:

[0046] 1) When the aircraft approaches the target altitude from 1100ft away, the distance between the aircraft and the target altitude changes from more than 1000ft to less than 1000ft. At this time, a warning sound (T1) and flashing lights should be generated to indicate that the aircraft is approaching the target altitude.

[0047] 2) When the distance between the aircraft and the target altitude increases from 1000ft-900ft to more than 1100ft and then decreases to less than 1000ft, a warning tone (T1) and flashing lights indicating that the aircraft is approaching the target altitude should be generated; when the distance between the aircraft and the target altitude increases from 1000ft-900ft to within 1000ft-1100ft and then decreases to less than 1000ft, there should be no warning tone (T1) and 5S flashing lights indicating that the aircraft is approaching the target altitude;

[0048] 3) When the distance between the aircraft and the target altitude increases from 900ft-200ft to more than 1000ft, a warning tone (T2) and a flashing light warning indicating deviation from the target altitude should be generated. The light flashes for 5 seconds and then stays on. If the distance between the aircraft and the target altitude decreases to less than 1000ft, the warning light indicating deviation from the target altitude should disappear.

[0049] 4) When the distance between the aircraft and the target altitude changes from less than 200ft to more than 200ft, a warning tone (T2) and a flashing light warning indicating deviation from the target altitude should be generated. The light flashes for 5 seconds and then stays on. If the distance between the aircraft and the target altitude decreases to less than 200ft, the warning light indicating deviation from the target altitude should disappear.

[0050] 5) If the steady light prompt for deviation from the target altitude is always on, the steady light prompt for deviation from the target altitude should disappear when the target altitude is manually changed or the altitude prompt is manually canceled.

[0051] Figure 2-Figure 3 Middle: The thick line represents the aircraft altitude trajectory, and the color is used to distinguish the display status. Black represents the normal state, no prompt; cyan represents approaching the altitude, flashing prompt (5s); dark yellow represents deviation from the altitude, constant prompt; yellow represents deviation from the altitude, flashing prompt (5s). T1 and T2 represent the altitude approach prompt tone and altitude deviation prompt tone respectively.

[0052] The present invention provides a method for prompting a manned transport aircraft approaching or deviating from a target altitude, which specifically includes:

[0053] Initialization: The target altitude approaching prompt state is invalid, and the target altitude deviation prompt state is invalid;

[0054] When |aircraft altitude - target altitude| changes from less than 1100ft to more than 1100ft, the approaching target altitude prompt state is set to be effective;

[0055] When |aircraft altitude - target altitude| changes from greater than 900ft to less than 900ft, the deviation from target altitude prompt state is set to be effective;

[0056] When |aircraft altitude - target altitude| changes from greater than 100ft to less than 100ft, the deviation from target altitude prompt state is set to be effective;

[0057] When the target altitude proximity prompt is valid and |aircraft altitude - target altitude| changes from greater than 1000ft to less than 1000ft, a target altitude proximity prompt sound (T1) and a 5S flashing light prompt are generated, and the target altitude proximity prompt is invalidated;

[0058] When the deviation from target altitude warning status is valid and |aircraft altitude - target altitude| changes from less than 1000ft to more than 1000ft, a deviation from target altitude warning sound (T2) and a flashing light warning are generated. The light flashes for 5S and then stays on, and the deviation from target altitude warning status is invalid.

[0059] When the deviation from target altitude warning status is valid and |aircraft altitude - target altitude| changes from less than 200ft to more than 200ft, a warning tone (T2) and a flashing light warning of deviation from target altitude are generated. The light flashes for 5S and then stays on, and the deviation from target altitude warning status is invalid.

[0060] If the light is always on, the light prompt should disappear when the target altitude is changed manually or the altitude prompt is canceled manually.
