| Popis: | The purpose of an aircraft takeoff performancemonitoring system is to provide to the pilot information pertaining to the level of safety with which a takeoff is proceeding. The concept of a takeoff performance monitoring system is not new. Instruments have been developed and flight-tested. However, the inclusion of a takeoff performance monitoring system as a standard instrument has yet to be embraced by manufacturers and operators. A simple theoretical dynamicmodel was developed to investigate the feasibility of using an observer systemduring the roll and takeoff phases of aircraft operation to provide to the pilot the information that is needed to maneuver safely. The viability of this simple model was validated using a prototype device installed in a 19-passenger commercial turboprop aircraft. Unlike previous work in this field, the Global Positioning Systemwas proposed as the sole source of kinematic information. This provided the possibility that a takeoff performance monitoring system could be devised that would require no additional ground-based installation. A Global Positioning System receiver and data acquisition systemwere installed in an aircraft operated by an airline servicing far-northernCanadian airports. The experimental investigation that was conducted to validate the theoretical model and signal processing technique showed that it was possible to predict the displacement of an aircraft to within 15 m, the length of the test aircraft, in sufficient time to aid the pilot in decision-making. |
