Leading and trailing edge device deflections during descent of an aircraft

摘要

A system (300) for increasing the descent rate of an aircraft may include a flight control computer(450), an edge control system (460), and a speedbrake control device (532). The flight control computer may be configured to compute a first setting for a leading edge device (150) and/or a trailing edge device (240) of an aircraft wing. The edge control system may be communicatively coupled to the flight control computer and may include an edge control device (453) having a plurality of control device positions (458) including a cruise position (462). The speedbrake control device may include a plurality of speedbrake detents (536) including a flight detent (542). The edge control system (460) may be configured to automatically command the leading edge device (150), the trailing edge device (240), or both, to a deflection angle corresponding to the first setting if the edge control device is in the cruise position and the speedbrake control device is in the flight detent.
