The invention provides an automatic flight safety mode switching method for wireless terminal products in air transport. The method comprises a flight safety mode entry method and a flight safety mode exit method. The automatic flight safety mode switching method for the wireless terminal products in the air transport provided by the invention realizes automatic entry and exit of flight safety modes of the wireless terminal products through the combination of GPS (Global Positioning System) positioning, GPS parameters and cell information assisted positioning and other means, so that the wireless terminal products can automatically manage the flight modes, and the wireless terminal products can be ensured to timely enter the flight safety modes, thus interferences with the flight of an aircraft can be avoided; and meanwhile, coordination and cooperation between data acquisition, data transmission and flight safety of the wireless terminal products can be guaranteed.
