HOW IT WORKS
FMS began life as a computer tasked with automating the process of building a flight plan from numerous waypoints. The latest FMS units are integrated throughout much of an air transport category aircraft’s avionics suite. The modern FMS’ ability to utilize WAAS GPS technology gives it unparalleled vertical and lateral approach guidance capabilities. Flight management computers can auto-tune the variety of nav frequencies demanded on a cross-country flight. Today’s FMS is capable of blending GPS navigation with VOR, VOR-DME and inertial navigation when needed.
