Some approaches are indicated for determining, and if necessary raising, the potential utilisation of training equipment, the objectives being:

—to reduce costs;

—to avoid or defer new capital investments;

—to secure more flexible rostering through increased

availability.

The problem is approached from a systems standpoint.

The investigation has been mainly confined to Link equipment, but the solution can be utilised for all auxiliary equipment, e.g. radar, where failures occur during or outside the use phase. Visual aids and pure flight aspects such as motion are not taken into consideration.
