An automatic flight control apparatus for aircraft having the desired attitude of the aircraft in a balanced relation to the action speed of the aircraft and utilizing this reference signal to generate a difference signal which corresponds to the difference between the reference signal and a signal representing the actual attitude of the aircraft; this latter signal then is used as one of the control parameters. The difference signal is fed to a control system through a limiter having a limiting range to avoid feeding excessively large difference signals into the control system and thus preventing unstable flight.
