Keywords: take-off, performance monitoring, performance prediction

The role of a take-off performance monitor is to determine whether the take-off manoeuvre is developing as desired or otherwise. Depending on design criteria, the system usually either compares the achieved performance against a pre-determined threshold, or else looks ahead and attempts to predict the future performance along the run. Whilst offering significant advantages over the former, the latter type relies on accurate prediction and the capability of looking as far ahead as possible to provide early warning of any impending anomaly to the crew. This paper discusses the predictive approach adopted in the design of a performance monitoring algorithm and presents the results obtained from flight testing using the College of Aeronautics’ Jetstream-100 flying laboratory.
