During the Portable Emergency Location Transmitter (ELT) preflight check, which condition indicates the device is properly secured?

• A. Locking pin is in place
• B. Velcro restraint strap is secure
• C. ELT casing is closed
• D. Gasket is intact

Answer: (A)

The key idea is that securing a portable ELT is about preventing movement and accidental arming. The locking pin in place provides a physical interlock that locks the activation/arming mechanism and keeps the unit from shifting or being triggered during handling or turbulence. Seeing that pin in place is the clearest, most reliable sign that the device is properly secured for flight. Other checks are useful but not definitive for securing. A Velcro restraint strap might hold the unit, but it can loosen or fail. The ELT casing being closed shows the enclosure is shut, but doesn’t guarantee the activation mechanism is prevented from moving. The gasket being intact matters for moisture protection, not for securing the device to its mounting.
