An airline distress system is provided for an airplane. The airplane includes a pilot cockpit and a transponder for transmitting signals to an air traffic controller. 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.
