Meaning: Identification Friend or Foe

A transponder-based system of aircraft identification, used to distinguish friendly craft from enemy craft.

The system essentially uses a "Question and Answer" routine between one aircraft and another. A correct response leads to the questioned aircraft being identified as friendly. In this respect, IFF can be considered a Challenge-response Authentication system.

The interrogation process is undertaken automatically, with no direct pilot / operator intervention necessary.

IFF systems can also be incorporated into missile and or defence systems, thus preventing them from firing on / acquiring "friendly" targets. IFF transponders may also be fitted to civilian aircraft for the same reason.
