Title: Vertical navigation device for jet aircraft. Final report

Technical Report ·
OSTI ID:5751103

The Vertical Navigation device for jet aircraft was completed within the limits of the budget. The device was demonstrated to representatives of the FAA, DOE, Delta Airlines and Eastern Airlines on 15 Dec 1982 at Aviation Electronics in Chamblee, Georgia. The device performed as it was intended to do and the demonstration was well received by all. Eastern is involved with another energy management system at present and decided to wait until those tests are complete before undertaking any other system tests. At this time Delta remains undecided as to running a test program. The energy aspects of the V-NAV program are impressive. Proper guidance for airliners in the vertical plane could save at least 3% of the fuel burn. This amounts to about 50 gallons per flight hour on a Boeing 727 airplane. Based on the projected cost of the device, it would pay for itself about 10 times in one year if installed and properly utilized by a pilot. Simple mathematics reveals that millions of gallons of jet fuel could be saved if the device was used in all jet transport aircraft. There are no apparent reasons that the device would not work as planned. Pilot acceptance of another cockpit aid would be the only possible problem. This could be solved with proper training and implementation into the system.
