I haven't seen any stats, but I feel the number of survivable
crashes where an ELT assisted in the rescue is very small. On the
water, a large number of rescues have been the result of EPIRB
activations. I've heard ELTs referred to as ballast, since the
most useful thing they do is move the CG aft.

Do you know if there is a mandated position on any plane where the ELT
must be installed? Or is it mfg preference (so to properly balance CG,
etc)
