Aircraft flight control systems that act symmetrically to create aerodynamic drag

An aircraft control system, comprising:

• a flight control processor configured to simultaneously command
• (1) deflection of a first empennage control surface to cause a first drag force and at least one of a first yawing moment or a first pitching moment on an aircraft;
• and
• (2) deflection of a second empennage control surface to cause a second drag force and at least one of a second yawing moment or a second pitching moment on the aircraft,
• wherein at least one of:
• the first and second yawing moments destructively combine to generate a resultant yawing moment about a center of gravity of the aircraft that is less than one or both of the first and second yawing moments, or
• the first and second pitching moments destructively combine to generate a resulting pitching moment about a center of gravity of the aircraft that is less than one or both of the first and second pitching moments, and
• wherein the first and second drag forces constructively combine to generate a resultant drag force on the aircraft.
