Introduction

With modern aircraft the basic aircraft provides CAT II/CAT III as inherent functions of the basic design standard of the aircraft.

Therefore, typical related “Autoland” tasks are covered by the respective AMM Task driven from the maintenance program.

Typically, it is not necessary for the introduction of additional or special recommendations for scheduled maintenance tasks.

Never the less, operators are expected to demonstrate compliance with supplemental national requirements whenever applicable.

Background
 
Regulatory approval for Autoland was first given in 1968 with the first CAT III landing taking place in Jan 1969 (Sud Aviation Caravelle).
 
Early adopters of Category III technology include The Hawker Siddeley HS Trident, Boeing B747-200 and Concorde. In 1974, the Airbus A300 was certified for Category III A and in 1983 the Airbus A310 achieved certification followed by the Airbus A300-600 in 1984 which achieved CAT III B.
 
Fail-operational automatic landing was first used for these types of operations, but it was found useful to develop fail-passive capability in order to comply with operational requirements.
