ABSTRACT:
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.
