mobile phones

As Mike said, text messages and some 911 signals require much less
power and signal to go through. (Mobile phone software enforces a
"quality of service" threshold; if it cannot be met or exceeded for a
voice call, it will not go through, but this threshold is very
different for text and emergency calls.)

I landed out ~50 miles south lf Moriarty a couple of years ago and my
mobile didn't work; it showed a weak analog signal but wouldn't place
calls. But 911 worked, and when I explained by situation to the
operator, she got called my crew number and we got hooked up.

Where were you? about Claunch? That is some desolate country.

Lincoln Station, maybe 15 miles east of Claunch. I wonder if my wing
stand is sitll there ...

Is that what I can see on Google Earth? :-)

why do it in the air?

I've done it to call the Tower and get a landing clearance after my
radio faile

If many consider it unsafe to drive
and talk, why do it in the air?

Well, I don't but, some would answer because it is unusual to be passing
obstructions at high speed an arms length away in a glider - gaggles not
withstanding.

I've had it ring at 2500'agl at which point I told whoever (my wife
and curtly too) that I was busy flying and then shut it off (I forgot
to shut it off prior to launch). If many consider it unsafe to drive
and talk, why do it in the air?


First, there are hundreds of thousands of pilots trained to verbally copy
and read back complicated airtraffic clearances while flying extremely
complex aircraft. For these pilots, a duplex phome conversation while
flying a simple glider is childs play. However, if it bothers you, don't do
it.

BTW, I don't think using satellite phones aboard an aircraft is prohibited
by FCC regulations.
