The Avionics Department of Pentastar Aviation was granted an FAA STC for the first airborne high speed data system installed in Gulfstream series aircraft capable of transmission speeds up to 256 kbps.

What this means, in plain English, is that data services are now available to travelers in the air, at speeds that are comparable to ground based users. The true benefit of this system is that Internet, e-mail, phone, and fax devices can all operate in harmony with no loss of speed
