LRU
FORCE2C
Don’t let anyone tell you otherwise. Achieving certifiability is a serious business that can involve almost uncountable man hours and dollars. The COTS approach to certifiability is simpler and less expensive than doing it yourself –we’ve invested upfront and will partner with you to make the process more straightforward - and more cost-effective.

AIS Air Data Test System
F-16
The primary function of the Air Data Test System (ADTS) is to perform testing and fault isolation of pneumatic-type Units Under Test (UUTs). To test a UUT, the operator connects the associated Line Replaceable Unit (LRU) Integrated Test Adapter (ITA) to the rackmount Avionics Intermediate Shop (AIS) test station. The operator connects the ADTS to the IAIS via an RS-232 Interface and then finally, connects the UUT to the ADTS using the supplied cables and hoses.
