If an aircraft's emergency locator transmitter (ELT) was last inspected 11 months ago, what action can you take?

The Emergency Locator Transmitter (ELT) is a crucial safety device on aircraft, designed to assist search and rescue operations in the event of an accident. The regulations typically state that an ELT must be inspected periodically, often every 12 months, to ensure it is functioning correctly. If the ELT was last inspected 11 months ago, it remains compliant with the inspection requirements, as it has not exceeded the maximum interval for inspection.

Departing with the ELT under these circumstances is appropriate, as the device is still capable of performing its intended function. The situation indicates that there is no immediate safety hazard regarding the ELT's operation, and you have complied with the regulatory requirements set forth.

The other options imply taking actions that are unnecessary since the ELT has not yet reached the point where it must be inspected again. Delaying departure or refusing to take off would not be justified in this case, considering the device is still within the acceptable inspection timeframe. Notifying authorities would also not be warranted since the ELT is functioning properly and adheres to the inspection schedule.
