Angle of attack display
View Patent ↗An aircraft safety system includes a Stall/Spin Warning & Recovery Computer, an angle of attack sensor, a side slip sensor and an angle of attack display. The Stall/Spin Warning and Recovery Computer detects whether the aircraft is in a safe condition or an unsafe condition. The angle of attack display includes a first configuration that displays information indicative of safe aircraft condition when the orientation detector detects a safe condition and a second configuration that displays information indicative of unsafe aircraft condition when the computer detects an unsafe condition. The display may transition from the first configuration to the second configuration when the orientation detector detects an unsafe condition and then to a third configuration, which may include visual control-input instructions that enable recovery to a safe condition.
1. An aircraft angle of attack display, comprising:
a first content configuration, comprising a representation of a first angle of attack, that displays information indicative of a safe aircraft condition,
a second content configuration, comprising a representation of a second angle of attack, that displays information indicative of an unsafe aircraft condition, and
a third content configuration, comprising visual control-input instructions that replace the representation of the second angle of attack when one or more detected conditions indicate the aircraft has failed to return to a safe aircraft condition.
2. The display of claim 1 , wherein the control-input instructions comprise elevator and rudder manipulation instructions that enable a pilot to return the aircraft to a safe condition.
3. The display of claim 1 , wherein the unsafe condition comprises at least one of an impending stall, an impending spin, an actual stall, and an actual spin.
4. The display of claim 1 , wherein the second configuration is replaced with the first content configuration when a safe condition is detected.
5. The display of claim 1 , wherein the third configuration is replaced with the first content configuration when a safe condition is detected.
6. The display of claim 1 , wherein the third configuration is altered as correct control-inputs are performed.
7. The display of claim 1 , wherein the first and second configurations display information indicative of the aircraft's potential for stalling or spinning.
8. The display of claim 1 , wherein the angle of attack display is integrated into a primary flight display, a heads-up display, a standby attitude and heading indicator, or an integrated standby display unit.
9. An aircraft safety system comprising:
a Stall/Spin Warning and Recovery Computer that detects whether the aircraft is in a safe condition or an unsafe condition, and
an angle of attack display comprising
a first content configuration, comprising a representation of a first angle of attack, that displays information indicative of a safe condition when the Stall/Spin Warning and Recovery Computer detects a safe condition,
a second content configuration, comprising a representation of a second angle of attack, that displays information indicative of an unsafe condition when the Stall/Spin Warning and Recovery Computer detects an unsafe condition, and
a third content configuration comprising visual control-input instructions that enable recovery to a safe condition, wherein the visual control-input instructions replace the representation of the second angle of attack when there is a stall/spin warning.
10. The system of claim 9 , wherein the instructions comprise elevator and rudder manipulation instructions that enable a pilot to return the aircraft to a safe condition.
11. The system of claim 9 , wherein the unsafe condition comprises at least one of an impending stall, an impending spin, an actual stall, and an actual spin.
12. The system of claim 9 , wherein the second content configuration is replaced with the first content configuration when a safe condition is detected.
13. The system of claim 9 , wherein the third content configuration is altered as correct control-inputs are performed.
14. The system of claim 9 , wherein the first content configuration displays information indicative of the aircraft's potential for stalling or spinning.
15. The system of claim 9 , wherein the angle of attack display is integrated into a primary flight display, a heads-up display, a standby attitude and heading indicator, or an integrated standby display unit.
16. A method for providing control-input instructions to a pilot of an aircraft comprising:
detecting whether the aircraft is in a safe condition or an unsafe condition,
displaying a first content configuration, comprising a representation of a first angle of attack, on an angle of attack display when the safe condition is detected,
replacing the angle of attack display with a second content configuration, comprising a representation of a second angle of attack, when the unsafe condition is detected, and
replacing the representation of the second angle of attack with visual control-input instructions enabling recovery of the aircraft to a safe condition, when one or more detected conditions indicate the aircraft has failed to return to a safe aircraft condition.
17. The method of claim 16 , wherein the control-input instructions comprise elevator and rudder manipulation instructions that enable a pilot to return the aircraft to a safe condition.
18. The method of claim 16 , wherein the unsafe condition comprises at least one of an impending stall, an impending spin, an actual stall, and an actual spin.
19. The method of claim 16 , comprising replacing a content of the second content configuration when a safe condition is detected.
20. The method of claim 16 , comprising altering the visual control-input instructions as correct control-inputs are performed.
21. The method of claim 16 , wherein the first content configuration provides an indication of the aircraft's potential for stalling or spinning.
22. The method of claim 16 wherein the angle of attack display is integrated into a primary flight display, a heads-up display, a standby attitude and heading indicator, or an integrated standby display unit.
