Which ELT(s) have an additional preflight safety check?

• A. TechTest and TechTest Type 2 ELT
• B. 406 MHz ELT
• C. 121.5 MHz ELT
• D. All ELTs

Answer: (A)

The main idea here is that some special ELTs used for training require an extra safety verification before flight. TechTest and TechTest Type 2 ELTs are designed for testing and practice, so they include an additional preflight safety check to prevent unintended transmissions and to confirm the unit’s arming/disarming status is correct before use. This extra step helps avoid false distress signals during preflight and ensures the device is in the proper test mode. Standard ELTs, like the 406 MHz or the older 121.5 MHz units, follow their regular preflight checks and don’t involve this extra safety verification. Saying all ELTs have it would be inaccurate because only these TechTest variants specify the additional preflight safety check.
