I'm curious, are there aircraft out there with an ELT "test" switch in the cockpit that the pilot can use for this test?
In a Cessna 150, to gain access to the ELT so you can manually turn it on, you have to remove the aft interior cabin wall to reach the ELT's manual transmiter switch. (a good way to put your back out!) Or there's an exterior access panel as well.
This process seems like a pain...compared to a cockpit switch.
PS. You can also test your ELT by landing REALLY hard and then tuning your COM to 121.5
