The airline distress system includes an auxiliary transponder 10 that transmits auxiliary signals to the air traffic controller. The auxiliary transponder is preferably disposed outside of the pilot cockpit and inaccessible to airplane crew and passengers. In one embodiment, a sensor 16 is operatively coupled with the cockpit door, and a switch 20 communicates with the sensor 16 and the auxiliary transponder 10. The auxiliary transponder 10 is configured to be automatically activated by the switch 20 according to a signal from the sensor that the cockpit door has been opened. |
