ABSTRACT:
Disclosed is a flight management computer modification that provides a pilot of an aircraft with a list of alternate landing destinations at which he can land the aircraft in case of an emergency on board or due to some reason why he cannot land at an intended destination. Each of the alternate landing destinations is displayed with data regarding the distance between the aircraft's present position and each of the alternate destinations, the estimated time of arrival to fly the aircraft to each of the alternate destinations and an estimate of the fuel remaining on board the aircraft if the aircraft were to land at the alternate destinations. The data allows the pilot to compare the benefits of landing at one of the alternate destinations versus landing at another. The data is calculated assuming a direct flight from the aircraft's present position to the alternate as well as assuming a missed approach at the intended destination and a flight from the intended destination to the alternate landing destination. The computational time required to produce the data for the pilot is minimized by increasing the size of the integration steps used by the flight management computer to calculate estimated time of arrival and fuel remaining and by using the flight management computer's precalculated values for optimum climb and descent angles.
