Abstract

A flight data transmission and storing system includes an on-board flight monitoring component for gathering standard flight data, including flight statistics and cockpit voice data, on an airplane and transmitting the data via a commercial or private satellite network to a central data repository at a secure location on the ground. The data may be sent in Internet Protocol (IP) format or other proven communication format for voice/data transmission. The flight data preferably is relayed to a data repository maintained by the FAA or other responsible governmental agency or licensed partner. The flight data can then be immediately retrieved in the event of an accident, to assist in a mid-flight crisis, for preventative or predictive maintenance, and/or for flight personnel training.
