For what it's worth, I made a three hour cross-country flight and
found my cell phone was on all the time when I went to cancel my flight
plan. On the way home I played with it in the cockpit (one hand firmly on
the controls) and found not one iota of problem -- including the KAP-140
installed in the 172SP. I do, however, turn it off when I can remember
because of the purported (implied) problems associated with the cell-phone
system on the ground. It (the cell phone) is virtually worthless in the
cockpit with the high ambient noise level anyway.

It can be useful as a locating device, I think (assuming that your ELT is
not being helpful). If your cell phone is on and someone calls it, I think
that they can determine which cell the phone is communicating with even if
no one can answer.


All the best,
