How much G force is required to activate an Emergency Locator Transmitter (ELT)?

2 Gs
3 Gs
4 Gs
5 Gs

The correct answer is: 4 Gs

The correct answer is based on the standard specifications for Emergency Locator Transmitters (ELTs), which are designed to activate in the event of a significant impact or crash. The threshold of force, specifically measured in Gs, determines the sensitivity of the ELT and its ability to respond appropriately to an emergency situation. In aviation, the common standard for many ELTs is a G force threshold of around 4 Gs. This level ensures that the device will activate during a crash scenario while minimizing the likelihood of false activations due to normal turbulence or other non-emergency conditions. Therefore, a requirement of 4 Gs reliably indicates a substantial impact, leading to the activation of the ELT, which is crucial for the search and rescue process after an aviation incident. This understanding is essential for aviation safety personnel, including flight nurses, as it relates directly to emergency preparedness and response protocols.
