Description

Technical Field

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

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

[0003] The pilot sets the aircraft's target altitude 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. The method and device provide prompting timing and method for approaching or deviating from the target altitude from two aspects: approaching or deviating from the target altitude from above the target altitude and approaching or deviating from the target altitude from below the target altitude. This enables the pilot to 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 departing from a target altitude, comprising:

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

[0007] S2. Determine whether the current altitude deviation is greater than the stored altitude 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 1100 ft. If so, proceed to S9; if not, proceed to S4;

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

[0010] S5. Determine whether the stored altitude deviation is less than a first preset deviation altitude, and whether the current altitude deviation is greater than the first preset deviation altitude. If so, set the deviation from target altitude prompt state to be invalid and proceed to S9; if not, proceed to S9;

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

[0012] S7. Determine whether the stored altitude deviation is greater than 1000 ft. If not, proceed to S8. If so, if the light is always on, turn off the light, and disable the target altitude approaching prompt, proceed to S9. If the light is very bright, disable the target altitude approaching prompt, 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 from target altitude prompt state to be valid and proceeding to S9; if not, proceeding to S9;

[0014] S9. Update the stored height deviation according to the current height deviation and return to S1;

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

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

[0017] Optionally, also include;

[0018] When the light remains on and an updated target altitude is received or the light is manually turned off, 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 altitudes are 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 method and device for prompting an aircraft when it approaches or deviates from a target altitude.

[0030] The present invention will be further described in detail below with reference to 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. The altitude deviation is the absolute value of the difference between the flight altitude and the target altitude.

[0033] S2. Determine whether the current altitude deviation is greater than the stored altitude 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 1100 ft. If so, proceed to S9; if not, proceed to S4;

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

[0036] S5. Determine whether the stored altitude deviation is less than a first preset deviation altitude, and whether the current altitude deviation is greater than the first preset deviation altitude. If so, set the deviation from target altitude prompt state to be invalid and proceed to S9; if not, proceed to S9;

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

[0038] S7. Determine whether the stored altitude deviation is greater than 1000 ft. If not, proceed to S8. If so, if the light is always on, turn off the light, and disable the target altitude approaching prompt, proceed to S9. If the light is very bright, disable the target altitude approaching prompt, 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 from target altitude prompt state to be valid and proceeding to S9; if not, proceeding to S9;

[0040] S9. Update the stored height deviation according to the current height deviation and return to S1;

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

[0042] When the deviation from target altitude prompt status changes from valid to invalid, a second prompt tone is played once and a flashing light prompt is given 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 departing from a target altitude provided by the present invention is as follows:

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

[0046] 1) When the aircraft approaches the target altitude from 1100 ft away, and the distance to the target altitude decreases from more than 1000 ft to less than 1000 ft, a warning tone (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, the target altitude approaching tone (T1) and flashing lights should be emitted; 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, the target altitude approaching tone (T1) and 5-second flashing lights should be eliminated;

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

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

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

[0051] Figure 2-Figure 3 Center: The thick line represents the aircraft's altitude trajectory, and the color-coded display states are used to distinguish between them. Black indicates normal operation (no alert); cyan indicates approaching altitude, with a flashing alert (5 seconds); dark yellow indicates deviation from altitude, with a constant display; and yellow indicates deviation from altitude, with a flashing alert (5 seconds). T1 and T2 indicate the altitude approach and altitude deviation alert tones, respectively.

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

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

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

[0055] When |aircraft altitude - target altitude| changes from more than 900ft to less than 900ft, the deviation from target altitude prompt state is enabled;

[0056] When |aircraft altitude - target altitude| changes from more than 100ft to less than 100ft, the deviation from target altitude prompt state is enabled;

[0057] When the target altitude proximity status is valid and |aircraft altitude - target altitude| changes from more than 1000ft to less than 1000ft, a target altitude proximity alert tone (T1) and a 5S flashing light prompt are generated, and the target altitude proximity status 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 tone (T2) and a flashing light will be generated. The light will flash for 5 seconds and then stay on, and the deviation from target altitude warning status will be 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 deviation from target altitude warning tone (T2) and a flashing light will be generated. The light will flash for 5 seconds and then stay on, and the deviation from target altitude warning status will be invalid.

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