A method and systems for controlling an aircraft during descent are provided. The control system includes an input device configured to receive a speed margin for the vehicle and a processor communicatively coupled to the input device wherein the processor is programmed to automatically determine a flight path of the vehicle that is shallower than an idle flight path for the vehicle and generate a flight control surface control signal configured to maintain the determined flight path using the received speed margin. The control system further includes an output device communicatively coupled to the processor. The output device is configured to transmit the flight control surface control signal to a flight control system of the vehicle.
