Common use of Inherent Availability (Ai Clause in Contracts

Inherent Availability (Ai. Ai is availability, only with respect to operating time and corrective maintenance. Ai is useful in determining basic operational characteristics under conditions that might include testing in a contractor's facility or other controlled facility. Ai provides a very poor estimate of true combat potential for most systems, because it provides no indication of the time required to obtain necessary field support. This measure should normally not be used to support an operational test. Ai = OT OT + TCM
