Abstract

A digital power controller for an aircraft having a computer controlled propulsion system is disclosed. A movable handle is in electronic communication with a computer of the propulsion system. The handle is positionable is a neutral location for maintaining the aircraft at a substantially constant velocity and for resetting power command functions. The handle is also positionable in locations forward the neutral location for commanding increasing acceleration rates of the aircraft. The handle is positionable in locations aft the neutral location for commanding increasing deceleration rates of the aircraft. A switch associated with the movable handle is engagable at the forward end aft positions for commanding velocity hold and for permitting reposition of the handle to the neutral location for resetting power command functions.

Claims

1. A digital power controller for an aircraft having a computer controlled propulsion system, comprising:

(a) a movable handle in electronic communication with a computer of said propulsion system, said handle being positionable in a neutral location for maintaining the aircraft at a substantially constant velocity and for resetting power command functions,

said handle being positionable in locations forward said neutral location for commanding increasing acceleration rates of said aircraft,

said handle being positionable in locations aft said neutral location for commanding increasing deceleration rates of said aircraft; and

(b) switching means associated with said movable handle, said switching means engagable at said forward and aft positions for commanding velocity hold and for permitting reposition of said handle to said neutral location for resetting power command functions.

2. The digital power controller of claim 1 wherein said moveable handle further includes a vernier control switch for incremental adjustments in aircraft velocity.

3. The digital power controller of claim 2 wherein said switching means includes:

(a) velocity hold switching means for communicating with said computer to maintain the aircraft velocity at a substantially constant speed and for activating said vernier control switch; and

(b) detent switching means for communicating with said computer to disengage velocity hold and to disengage the vernier control switch, thereby permitting power command functions.

4. The digital power controller of claim 1 further including linear handle guide means for providing movement of said handle in a substantially linear direction.

5. The digital power controller of claim 1 further including means for providing radial movement of said handle.

6. A digital power controller for an aircraft having a computer controlled propulsion system and a center console of the type including a pedestal disposed in a central location between the pilot'"'"'s knees, and below and aft the front instrument panel of the aircraft, said digital power controller comprising;

(a) a housing mounted within said pedestal;

(b) a movable handle attached to said housing and in electronic communication with a computer of said propulsion system, said handle being positionable in a neutral location for maintaining the aircraft at a substantially constant velocity and for resetting power command functions,

said handle being positionable in locations forward said neutral location for commanding increasing acceleration rates of said aircraft,

said handle being positionable in locations aft said neutral location for commanding increasing deceleration rates of said aircraft; and

(c) switching means associated with said movable handle, said switching means engagable at said forward and aft positions for commanding velocity hold and for permitting reposition of said handle to said neutral location for resetting power command functions.

7. The digital power controller of claim 6 wherein said moveable handle further includes a vernier control switch for incremental adjustments in aircraft velocity.

8. The digital power controller of claim 7 wherein said switching means includes:

(a) velocity hold switching means for communicating with said computer to maintain the aircraft velocity at a substantially constant speed and for activating said vernier control switch; and

(b) detent switching means for communicating with said computer to disengage velocity hold and to disengage the vernier control switch, thereby permitting power command functions.

9. The digital power controller of claim 6 further including linear handle guide means for providing movement of said handle in a substantially linear direction.

10. The digital power controller of claim 6 further including means for providing radial movement of said handle.
