Re when to change out flashlight batteries in ELTs: As I think about it, you
may well be right about changing out the batteries before the expiration,
maybe at the halfway point or some such. For the record, I'll check with my
A&P tomorrow and post the info.
Sorry for any misinformation: I'll try to straighten it out.

Was reviewing the "manual battery switch" issue tonight and reviewed this
old e-mail.
Ref David S's comment below, "If you have to mount it a distance from the
battery in order
> to reach it, you are compromising the crash safety that the master
disconnect provides."
I had also thought of that - but IF I put a ANL current limiter (BIG fuse)
within 1 to 5 inches of the positive battery terminal, and then run a fat
wire up to the instrument panel to the manual switch, even though the fat
wire is longer than 5-6 inches, it is NOT "unprotected", so, should meet the
guidelines that Bob Nuckolls frequently reminds us of.
So, I/we should be able to mount the battery up close to firewall - out of
reach (and not back by our knee) - 'cause we no longer have to have the
manual battery switch near the battery.
