A system for increasing a descent rate of an aircraft, the system comprising: a flight control computer configured to compute a first setting for a leading edge device and/or a trailing edge device of an aircraft wing; an edge control system communicatively coupled to the flight control computer and including an edge control device having a plurality of control device positions including a cruise position, wherein the edge control device is for enabling the flight crew to manually command a position of the leading edge device and/or the trailing edge device; a speedbrake control device having a plurality of speedbrake detents including a flight detent; and the edge control system configured to automatically command the leading edge device, the trailing edge device, 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, wherein: the first setting is selected to increase aerodynamic drag of the aircraft wing and wherein the flight control computer is configured to compute the first setting responsive, in part, to movement of the speedbrake control device to the flight detent; and the edge control system is further configured to automatically command the leading edge device, the trailing edge device, or both to the first setting responsive to an indication of loss of cabin pressure. a flight control computer configured to compute a first setting for a leading edge device and/or a trailing edge device of an aircraft wing; an edge control system communicatively coupled to the flight control computer and including an edge control device having a plurality of control device positions including a cruise position, wherein the edge control device is for enabling the flight crew to manually command a position of the leading edge device and/or the trailing edge device; a speedbrake control device having a plurality of speedbrake detents including a flight detent; and the edge control system configured to automatically command the leading edge device, the trailing edge device, 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, wherein: the first setting is selected to increase aerodynamic drag of the aircraft wing and wherein the flight control computer is configured to compute the first setting responsive, in part, to movement of the speedbrake control device to the flight detent; and the edge control system is further configured to automatically command the leading edge device, the trailing edge device, or both to the first setting responsive to an indication of loss of cabin pressure. the first setting is selected to increase aerodynamic drag of the aircraft wing and wherein the flight control computer is configured to compute the first setting responsive, in part, to movement of the speedbrake control device to the flight detent; and the edge control system is further configured to automatically command the leading edge device, the trailing edge device, or both to the first setting responsive to an indication of loss of cabin pressure.
