Method And Apparatus For Onboard Monitoring Of Aircraft Takeoff

US Patent:
4773015, Sep 20, 1988
Filed:
Feb 6, 1985
Appl. No.:
6/698866
Inventors:
James W. Leland - San Antonio TX
James E. Kirkpatrick - Canyon Lake TX
Assignee:
Accutold - San Antonio TX
International Classification:
G01C 2100, G06F 1550
US Classification:
364427
Abstract:
An aircraft takeoff monitor having distance traveled sensors for measuring the distance traveled after the initiation of the takeoff roll. These sensors are interfaced with an onboard computer to provide the computer with information on the actual distance traveled by the aircraft since the takeoff run was initiated. The computer is programmable to receive predetermined input signals, including runway length, real-time inputs, and the initiation time, with the computer constantly generating a predicted ground distance that should be traveled since the initiation of the takeoff run. The computer is further programmed to compare the actual ground distance traveled to the predicted ground distance which should have been traveled and provide a display signal representative of this comparison on an onboard display instrument. Simultaneously the computer further continuously computes a predicted stopping distance for the aircraft at any time after the initiation of takeoff, adding the actual distance traveled to the predicted stopping distance, and subtracting these additive distances from the runway length, thereby generating a stopping distance display signal which is displayed on the onboard display instrument to indicate the distance the aircraft would predictably stop from the end of the runway.
