Due to inefficiencies and associated cost incurred by taxi-in related delays in a busy airport, a new idea
has been proposed to efficiently command and control the landing ground run of medium to heavy
transport aircraft equipped with thrust reversers. The idea is based on the modulation of thrust reversers
installed on the aircraft. To demonstrate the efficiency of such a system, the complete equations of motion
as soon as the main gears touch the ground, up until the aircraft comes to a complete stop have been
developed. In addition to the thrust reversers, all effective control mechanisms during the landing process,
such as brakes and spoilers have been included in the mathematical model. By proposing a suitable
definition for an optimum landing ground run and its associated cost function different contour plots for
landing ground run vs. optimal control commands have been developed for a typical heavy transport. It is
further shown that a modulated thrust reverser could be an effective tool to command and control the
landing ground run of an aircraft. The results of simulation program for a typical heavy transport, such as
a B-747-100, show a possibility of 12% decrease in the time associated with taxi-in.r2001 Elsevier Science
