Abstract

A lever outputs a first signal level where the first signal level is based at least in part on the position of the lever and the first signal level is used to control a first set of rotors associated with a vertical propulsion system. A thumb controller (coupled to the vertical thrust lever) outputs a second signal level where the second signal level is based at least in part on the position of the thumb controller, the second signal level is used to control a second set of rotors associated with a horizontal propulsion system, and the thumb controller includes a detent associated with a recommended sustained maximum.

Claims (50)

1. A system, comprising:

a lever which is configured to output a first signal level, wherein:

the first signal level is based at least in part on the position of the lever; and

the first signal level is used to control a first set of one or more rotors associated with a vertical propulsion system; and

a thumb controller which is coupled to the lever and is configured to output a second signal level; wherein:

the second signal level is based at a least in part on the position of the thumb controller;

the second signal level is used to control a second set of one or more rotors associated with a horizontal propulsion system; and

the thumb controller includes a detent associated with a recommended sustained maximum.

2. The system recited in claim 1 , wherein:

at least one rotor in the second set of one or more rotors associated with the horizontal propulsion system is powered by a motor which in turn includes a magnet; and

the recommended sustained maximum is associated with an amount of current draw which will not demagnetize the magnet, even if the thumb controller is held at the detent associated with the recommended sustained maximum for a prolonged period of time.

3. The system recited in claim 1 , wherein the lever includes a second detent associated with zero vertical thrust.

4. The system recited in claim 1 , wherein:

the lever includes a second detent associated with zero vertical thrust; and

the system further includes a lock which is configured to lock the lever at the second detent associated with zero vertical thrust.

5. The system recited in claim 1 , wherein:

the lever includes a second detent associated with zero vertical thrust; and

the system further includes a lock which is configured to lock the lever at the second detent associated with zero vertical thrust, wherein the lock includes a ring lock.

6. The system recited in claim 1 , wherein:

the lever includes a second detent associated with zero vertical thrust; and

the system further includes a lock which is configured to lock the lever at the second detent associated with zero vertical thrust, wherein the lock includes a cam lock.

7. The system recited in claim 1 , further comprising a momentary push button which is configured to clear at least one displayed message.

8. The system recited in claim 1 , further comprising a momentary push button which is configured to mark an event.

9. The system recited in claim 1 , further comprising a momentary push button which is configured to mark an event, including by storing one or more coordinates.

10. The system recited in claim 1 , wherein the lever is door-mounted.

11. A method, comprising:

providing a lever which is configured to output a first signal level, wherein:

the first signal level is based at least in part on the position of the lever; and

the first signal level is used to control a first set of one or more rotors associated with a vertical propulsion system; and

providing a thumb controller which is coupled to the lever and is configured to output a second signal level, wherein:

the second signal level is based at least n part on the position of the thumb controller;

the second signal level is used to control a second set of one or more rotors associated with a horizontal propulsion system; and

the thumb controller includes a detent associated with a recommended sustained maximum.

12. The method recited in claim 11 , wherein:

at least one rotor in the second set of one or more rotors associated with the horizontal propulsion system is powered by a motor which in turn includes a magnet; and

the recommended sustained maximum is associated with an amount of current draw which will not demagnetize the magnet, even if the thumb controller is held at the detent associated with the recommended sustained maximum for a prolonged period of time.

13. The method recited in claim 11 , wherein the lever includes a second detent associated with zero vertical thrust.

14. The method recited in claim 11 , wherein:

the lever includes a second detent associated with zero vertical thrust; and

a lock is configured to lock the lever at the second detent associated with zero vertical thrust.

15. The method recited in claim 11 , wherein:

the lever includes a second detent associated with zero vertical thrust; and

a lock is configured to lock the lever at the second detent associated with zero vertical thrust and the lock includes a ring lock.

16. The method recited in claim 11 , wherein:

the lever includes a second detent associated with zero vertical thrust; and

a lock is configured to lock the lever at the second detent associated with zero vertical thrust and the lock includes a cam lock.

17. The method recited in claim 11 , wherein there is a momentary push button which is configured to clear at least one displayed message.

18. The method recited in claim 11 , wherein there is a momentary push button which is configured to mark an event.

19. The method recited in claim 11 , wherein there is a momentary push button which is configured to mark an event, including by storing one or more coordinates.

20. The method recited in claim 11 , wherein the lever is door-mounted.
