Aircraft and method of controlling

1. A method of controlling an aircraft, the method comprising:

tracking, using at least one sensor, one of an input by a pilot or a biometric parameter of a pilot during flight of the aircraft;

determining, using a controller that is operatively connected to the at least one sensor, a lack of attention by the pilot or a depth of sleep of the pilot based on the biometric parameter;

customizing a timer based on the lack of attention by the pilot or a controlled rest;

controlling at least one system of the aircraft when a predetermined amount of lack of attention or a predetermined depth of sleep satisfies a predetermined threshold;

setting the timer based on a beginning of the lack of attention or the controlled rest;

providing a wake procedure when the timer reaches a predetermined time to prevent sleep inertia upon waking.

2. The method of claim 1 wherein the predetermined threshold indicates one of unacceptable absence or incapacitation of the pilot.

3. The method of claim 2 , further comprising automatically initiating a recovery procedure upon determination of the unacceptable absence or the incapacitation.

4. The method of claim 3 wherein the recovery procedure includes at least one of activating an audible signal on the aircraft, vibrating a seat of the pilot, unlocking a cockpit door, executing an automatic landing via a flight system, allowing remote control of the aircraft, or activating a distress tracker for the aircraft.

5. The method of claim 4 wherein allowing remote control of the aircraft further includes automatically updating a flight plan of the aircraft and executing the updated flight plan.

6. The method of claim 1 wherein tracking the input by the pilot includes tracking an input to any cockpit system.

7. The method of claim 1 , further comprising identifying a portion of a flight plan of the aircraft where lack of attention or controlled rest is allowable.

8. The method of claim 7 , further comprising providing an indication within a cockpit of the aircraft that the controlled rest is allowable.

9. The method of claim 1 wherein the wake procedure includes at least one of activating an audible signal on the aircraft or vibrating a seat of the pilot.

10. A method of controlling an aircraft, the method comprising:

tracking, using at least one sensor, a biometric parameter of a first pilot during flight of the aircraft;

determining, using a controller that is operatively connected to the at least one sensor, a depth of sleep of the first pilot based on the biometric parameter;

allowing a predetermined amount of depth of sleep;

providing a wake procedure to prevent the first pilot from entering REM stage sleep in order to prevent sleep inertia upon waking; and

modifying access to a system of the aircraft when the amount of depth of sleep satisfies a predetermined threshold.

11. The method of claim 10 , further comprising identifying a portion of a flight plan of the aircraft where controlled rest is allowable.

12. The method of claim 11 , further comprising providing an indication within a cockpit of the aircraft that the controlled rest is allowable.

13. The method of claim 12 , further comprising verifying secondary conditions, related to the controlled rest, before providing the indication.

14. The method of claim 13 wherein the secondary conditions including verifying at least one of: that a second pilot is present, that a second pilot is not sleeping, or that a second pilot is wearing a seat belt.

15. The method of claim 10 , further comprising tracking a second pilot's interaction with cockpit systems during a controlled rest of the first pilot.

16. The method of claim 10 , further comprising setting a timer based on the biometric parameter.

17. The method of claim 16 , further comprising providing a wake procedure when the timer reaches a predetermined time and wherein the wake procedure includes at least one of: activating an audible signal on the aircraft or vibrating a seat of the first pilot.

18. The method of claim 10 wherein the wake procedure includes at least one of: activating an audible signal on the aircraft or vibrating a seat of the pilot.

19. The method of claim 10 wherein the modifying access to the system includes at least one of moving a seat of the first pilot or denying access to the system for a predetermined amount of time.
