The electronics package for a Category II qualified business jet aircraft and the function of the various components of the system are described. These components include: dual Collins 51-RV-l VOR/ILS/G. S. receivers which provide and utilize beams along which the aircraft descends for a safe approach; a Collins AL-101 radio altimeter to determine altitude; dual flight directors for automatic and manual approaches; and a Collins 54W-1 comparator warning system, to name a few. A general rather than a technical approach is used.
