ABSTRACT:
A method and apparatus for providing an indication as to whether an aircraft can safely glide to a selected location. An electronic processor is provided with a manual data input, a Loran navigation system input, or electronic altimeter input, a memory, a display, and a processor program. Data representing the identity, location, and other features of a set of possible airport landing sites are stored in the memory. Data representing the aircraft flight performance parameters is entered manually. Based on the airport data, aircraft performance data, Loran data, and altimeter data, the program causes the processor to determine and display a predetermined number of nearest airports, the altitude required to glide to those airports from the aircraft's current location, or the difference between the distance to the airports and the distance the aircraft can glide from its current altitude, and whether the aircraft can safely glide to a selected airport.
