LEAD COMPENSATED ENGINES ONLY FLIGHT CONTROL SYSTEM

A backup engines-only flight control system accomplishes improved aircraft banking in response to commands by the use of a lead compensated transient differential thrust servo parameter. The lead compensated transient differential thrust servo parameter compensates for the ordinary sluggish banking response during engines-only flight control. Accordingly, because an aircraft equipped with the present invention will respond in a manner expected by pilots, safer backup engines-only flight control is achieved during emergency situations. The improvement comprises a means and method of detecting the magnitude of direction of commanded bank angle and generating a corresponding lead compensated transient differential thrust servo parameter.
