6.
Activate the ELT using the “ON” of “Test” Switch. A low quality AM
Broadcast Radio
Receiver should be sued to determine if energy is being
transmitted from the Antenna. When the Antenna of this Radio (tuning dial on
any setting) is held about 6 inches from the activated ELT Antenna, the ELT
Aural tone will be heard (see notes 2 and 3).
7.
Verify that all switches are properly labeled and positioned.
Note 1:
This is not a measured check. It only indicates that the G-Switch is working.
Note 2:
This is not a measured check, but it does provide confidence that the Antenna is
radiating with sufficient power to aid search and rescue. The Aircraft’s VHF
Receiver, tuned to 121.5 MHz, may also be sued. This Receiver, however, is
more sensitive and could pick up a weak signal even if the radiating ELT’s
Antenna is disconnected. Thus, it does not check the integrity of the ELT System
or provide the same level of confidence, as does an AM Radio.
Note 3:
Because the ELT radiates on the emergency frequency, the Federal
Communications Commission allows these tests to be conducted only within the
first 5 minutes after any hour.
