The use of cellular phones is not permitted from *any* aircraft. Not only for aviation safety reasons, but because of the havoc it wreaks with the cellular systems themselves. If a mobile comes up on multiple sites, the system will probably lock it out permanently to protect itself. The phone you are probably refering to is called "Airphone". It uses special equipment on a special frequency (950MHz band) and has special approval by the FAA and FCC for aircraft to ground communication. The phone in your hand is an ordinary *cordless* phone. The actual air to ground communications is performed by a transceiver mounted elsewhere on the aircraft. -- John Higdon | P. O.
