1. An apparatus comprising:
a lift control module configured to identify an undesired change in an airspeed for an aircraft; and further configured to identify a number of commands for a flight control system associated with a wing of the aircraft, wherein the number of commands is configured to cause the flight control system to maintain a lift of the aircraft for a desired trajectory while minimizing change in pitch attitude, and wherein the lift control module further comprises:
an airspeed change monitor configured to identify the undesired change in the airspeed using a current airspeed and a previous airspeed for the aircraft; and
a lift change compensation process in communication with the airspeed change monitor and configured to receive the undesired change in the airspeed, identify a change in the lift in response to the undesired change in the airspeed, and identify the number of commands configured to cause the flight control system to maintain the lift of the aircraft for the desired trajectory while minimizing change in pitch attitude.
