The functions and the operation of airline avionics systems, and their flight testing objectives and requirements are discussed. Data acquisition equipment developed for the evaluation and certification of a civil transport aircraft prototype is described. For the determination of flight path during automatic approaches and landings, an integrated system based on inertial positioning, radio altitude and pressure altitude during the approach, followed by photographic determination of the position during the landing, can be used on multiple CAT instrument landings system equipped runways in up to CAT II weather conditions. For the en route flight path determination, a positioning system based on the sequential measurement of the distance of the aircraft to multiple distance measuring equipment (DME) and tactical air navigation system ground stations, combined with velocity information from an inertial sensor system and altitude information from an air data system, can be used (multi-DME/inertial position reference system).
