Integrated Flight Trajectory Control Development Program.
Abstract
Previous IFTC programs have demonstrated by simulation the ability to compute four-dimensional reference trajectories and provide guidance commands to the pitch and role autopilot axes for vertical and lateral aircraft control, and to the autothrottle for thrust and accurate time-of-arrival control. The ability of the trajectory generator to respond to pilot-induced flight plan deviations and data-linked mission changes was also demonstrated. Conventional cathode ray tubes (CRTs) were utilized for flight plan graphics and alphanumeric display. The IFTC Development Program has been concerned with adding certain functions to increase the tactical flight management capabiliies of the concept. IFTC was integrated with the Firefly II advanced air-to-ground weapon delivery algorithms to provide ingress and egress flight path generation and control. The LSI-developed Mission Data Transfer System (MDTS) was added to the simulation to demonstrate the aid to mission planning and the rapid data initialization of the simulated airborne system. The CRT used for the Tactical Map Display was replaced by an Electronic Projected Map Display (EPMD), which allowed the combined display on one surface of the Tactical Planning Chart (TPC) image and the graphics generated image of the flight plan, including the aircraft image, hostile and friendly bogies, and ground threat envelopes. Pilot testing and evaluation of the concept was performed using the LSI man-in-the-loop cockpit simulator. (Author)
