In the beginning was the Link Trainer! It was from the Link Trainer that the simulator as we know it today descended. When the simulator was first introduced into airline service it was to some degree treated as a novelty. Instructors on the simulators fell into two categories—they were either in the minority, Link Trainer instructors, but in the main the fleet instructors from the aircraft types. They were ex-service RAF, Navy and CFS trained and they adapated themselves to the new form of aptitude tests. It is perhaps interesting that we look back over a quarter of a century to the time that BOAC, as it was, acquired its first simulator.
