Abstract

An aircraft, the aircraft including a whole-aircraft ballistic parachute that is coupled to the aircraft. The aircraft determines if a pre-activation action needs to be performed before activation of the whole-aircraft ballistic parachute. The aircraft also receives a whole-aircraft ballistic parachute activation request. The aircraft then issues a command to perform the pre-activation action and then activates the deployment of the whole-aircraft ballistic parachute. The aircraft then issues a command to perform a post-activation action.

Claims (53)

1 . A method performed by an aircraft, the aircraft including a whole-aircraft ballistic parachute that is coupled to the aircraft, the method comprising:

receiving, from an aircraft occupant, a whole-aircraft ballistic parachute deployment request; then

based upon the receipt of the ballistic parachute deployment request, both performing an action and also deploying the whole-aircraft ballistic parachute.

2 . The method of claim 1 , wherein the action includes increasing the altitude of the aircraft above the ground.

3 . The method of claim 1 , wherein the action includes decreasing the airspeed of the aircraft.

4 . The method of claim 1 , wherein the action includes controlling the reefing of the whole-aircraft ballistic parachute.

5 . The method of claim 4 , wherein the controlling the reefing includes restraining a reefing control line.

6 . The method of claim 4 , wherein the controlling the reefing includes restraining a reefing control line that is coupled to a reefing device.

7 . The method of claim 1 , wherein the action includes changing the heading of the aircraft.

8 . The method of claim 1 , wherein the action includes changing the attitude of the aircraft.

9 . The method of claim 1 , wherein the action includes displaying a visual indication on a display that is coupled to the processor.

10 . The method of claim 1 , further comprising, after deploying the whole-aircraft ballistic parachute, performing a second action.

11 . The method of claim 10 , wherein the second action includes controlling the reefing of the whole-aircraft ballistic parachute.

12 . The method of claim 11 , wherein the reefing of the whole-aircraft ballistic parachute includes releasing a reefing control line that is coupled to a reefing device.

13 . The method of claim 11 , wherein the controlling the reefing of the whole-aircraft ballistic parachute includes extending a reefing control line, which is coupled to a reefing device, and then releasing the reefing control line.

14 . The method of claim 10 , wherein the aircraft includes a transponder and wherein the action includes commanding the transponder to enter one of Mode A, Mode C, or Mode S.

15 . The method of claim 10 , wherein the second action includes activating an emergency locator transmitter.

16 . The method of claim 10 , wherein the second action includes setting a transmitter frequency of a communication radio to 121.5 MHz.

17 . The method of claim 10 , wherein the second action includes setting a transmitter frequency of a communication radio to 121.5 MHz and then transmitting a message on the transmitter frequency containing the aircraft type, the aircraft N number, the aircraft colors, the aircraft latitude and longitude coordinates, the fact that a whole-aircraft ballistic parachute has been deployed, and at least one phone number.

18 . The method of claim 10 , wherein the second action includes displaying a visual indication on a display that is coupled to the processor.

19 . The method of claim 10 , wherein the second action includes lowering the landing gear of the aircraft.

20 . An aircraft, the aircraft including a whole-aircraft ballistic parachute that is coupled to the aircraft, the aircraft configured to perform a method comprising:

receiving a whole-aircraft ballistic parachute deployment request from an occupant of the aircraft; then

based upon the receipt of the whole-aircraft ballistic parachute deployment request, both performing an action and also deploying the whole-aircraft ballistic parachute.

21. An aircraft, the aircraft including:

a whole-aircraft ballistic parachute that is coupled to the aircraft, the whole-aircraft ballistic parachute is configured to deploy based upon an electrical signal;

a pull-handle;

an autopilot that is operable to control the pitch, roll, and heading of the aircraft, the autopilot being operable to increase the altitude of the aircraft and to reduce the airspeed of the aircraft;

one or more memories having machine-readable instructions stored thereon; and

one or more processors, each of the one or more processors configured to read and execute a portion of the machine-readable instructions;

the aircraft configured to perform a method comprising:

based upon an occupant of the aircraft pulling on the pull-handle, receiving a whole-aircraft ballistic parachute deployment request from the occupant of the aircraft; then

based upon the receipt of the whole-aircraft ballistic parachute deployment request, both performing a first action and deploying the whole-aircraft ballistic parachute;

wherein the machine-readable instructions include the step comprising:

based at least upon the occupant of the aircraft pulling on the pull-handle, utilizing the autopilot to increase the altitude of the aircraft;

wherein the pull-handle is configured to be pulled by the occupant of the aircraft a first time and a second time;

wherein the pull-handle is configured to function, based upon the occupant pulling on the pull-handle the first time, as a first interface to the one or more processors;

wherein the pull-handle is configured to function, based upon the occupant pulling on the pull-handle the second time, as a second interface to the one or more processors;

wherein the machine-readable instructions include the step comprising:

based at least upon the occupant pulling on the pull-handle the first time, perform an analysis to determine whether a second action needs to be performed;

wherein the machine-readable instructions include the step comprising:

based at least upon the occupant pulling on the pull-handle the second time, activate the deployment of the whole-aircraft ballistic parachute regardless of whether the analysis determines that the second action needs to be performed;

wherein the machine-readable instructions include the step comprising:

based at least upon the deployment of the whole-aircraft ballistic parachute, controlling reefing of the whole-aircraft ballistic parachute, and wherein controlling reefing of the whole-aircraft ballistic parachute includes one or more of controlling a position of a reefing device, extending reefing control lines, or retracting reefing control lines.

22. The aircraft of claim 21 , wherein controlling reefing of the whole-aircraft ballistic parachute includes actuating an actuator.

23. The aircraft of claim 22 , wherein actuating the actuator includes actuating a linear actuator.

24. The aircraft of claim 22 , wherein actuating the actuator includes actuating a rotary actuator.

25. The aircraft of claim 21 , wherein the machine-readable instructions include the step of receiving data that indicates that the ballistic parachute has opened.

26. The aircraft of claim 21 , wherein the deployment of the whole-aircraft ballistic parachute causes fuel discharge from the aircraft.

27. The aircraft of claim 21 , wherein performing the analysis to determine whether the second action needs to be performed includes one or more of determining an altitude of the aircraft, determining an airspeed of the aircraft, determining if the reefing of the parachute should be controlled, determining a heading of the aircraft, or determining an attitude of the aircraft.

28. The aircraft of claim 21 , wherein controlling reefing of the whole-aircraft ballistic parachute includes controlling reefing of the whole-aircraft ballistic parachute based on airspeed of the aircraft.

29. The aircraft of claim 21 , wherein the machine-readable instructions include the step of displaying a message to aircraft occupants.

30. The aircraft of claim 29 , wherein the machine-readable instructions include the step of displaying a message including instructions to aircraft occupants.
