ABSTRACT:
A system for altering the lift/drag characteristics of powered general aviation aircraft whereby flight path control may be exercised. The control device operates in conjunction with such lift/drag altering devices, spoilers, dive brakes and the like, and is physically unitary with the pilot's operation of the throttle control. Utilizing a single control, the pilot may selectively maintain the craft without lift/drag modification, with automatic lift/drag modification at lower power settings such as under landing approach conditions and lift/drag modifications at higher power settings and without modifying the power setting. A vacuum operated valve having simple selectable operational modes provides flight path control desired. Vacuum distribution means, i.e., vacuum lines are provided from a vacuum source, to the vacuum valve and to the spoilers and dive brakes for bellows actuation of the lift/drag altering devices.
