A method for predicting and monitoring the takeoff performance of an aircraft uses information from one or more previous takeoffs of the aircraft to generate a prediction of the takeoff performance for the current takeoff. In the preferred embodiment, a takeoff profile for the current takeoff is generated and includes information about predetermined characteristics of the aircraft and information about ambient conditions at an airport from which the takeoff is being monitored. Expected performance data for the current takeoff is then generated from the takeoff profile and used to select a set of actual performance data previously stored from the one or more previous takeoffs. A selected "best fit" actual performance data set is then displayed in an appropriate fashion. Upon takeoff, a set of monitored performance data is generated as a function of one or more of sensed takeoff parameters. The monitored performance data set for the current takeoff is then displayed in conjunction with the actual performance data previously selected to provide the crew with an indication of the progress of the current takeoff.
