Installed System Test
The installed system tests are used to perform tests of the basic functions of the ELT system. These
tests do not give specified levels of performance for one or more of the functions of the ELT but they
do show that the system operates satisfactorily. If the results are unsatisfactory for a unit during one of
these tests, refer to the fault isolation flowcharts (Figures 103 to 105) to isolate the problem.
A. Self-test #1 (Started from Transmitter Unit)
NOTE: Consult with the responsible ATC/CAA/SAR for permission prior to performing self-test.
