Transponder "G-switch" spec?

[Dave Hyde]

Just curious: Does anyone now the longitudinal
acceleration spec for ELT activation?

TSO-C91a refers to RTCA DO-183, and that's priced outta
my range for a simple question like this.

Transponders have G-switches?

You didn't get the word?

Hey Dave, maybe it's time for a few Zzzz's. :)

The threshold spec for ELT inertia switch is 6g from a velocity of 3
ft/s or greater. Held in your hand with the forward direction facing
away from you, a swift "whip cracking" motion in the air should
activate it. Congrats on your engine.

Where's the best place to grip your airplane to do this if the spar is
internal? :p

It's not a question of where he grips it, it's a simple question of weight
ratios, a five ounce bird can not carry a one pound coconut! - Monty Python

One is really more than enough, thanks :-)

By the stick and throttle. Be sure to tighten
your harness.
