But these are still region-specific. Here in Region 1 we are most
definitely *not* allowed to use amateur equipment on board aircraft, even
a light aircraft of which the operator might be the sole occupant and
therefore his own PIC.

Likewise cellular phones. Although the technical specifications of the
systems in use, certainly GSM as used over here, means that once in the
air the handset would be unlikely to see many base stations as the
transmitting antennas of these would be aimed downwards at ground-based
users.

The phone service provided commercially on airliners is satellite based
and is specifically licensed for the purpose. Some airlines are
(unfortunately IMHO) experimenting with pico-cells inside the cabin to
allow passengers to use their own handsets, but the onward transmission
from the aircraft is by satellite.

It may be in the the UK, but here in the USA, some of the In Plane Phone
Communications, is done in the 800 Mhz band from Ground Stations. Our
Regulatory Agency, (FCC) setup a Radio Service just for Air Ground Phone
Communications. I can't remember the Actual Name offhand, but I am sure
that Phil can come up with it.
