Transponder: Difference between revisions

'''Transponders''' are radio beacons which make [[aircraft]] more identifiable on [[ATC]] displays and systems and by other aircrafts. Modern transponders support transmitting additional data such as an identification ('squawk') code and aircraft altitude. See more at {{wikipedia|Transponder (aeronautics)}}.

e.g.  

* 'squawk code' 7000 is set and used VFR flight in Europe, and while in the US 1200 in used fir the same VFR.

* IFR aircraft's will have an 'attributed code' by the ATC services at Delivery Clearance time, typically at startup time. The code is ATC selected in a range of "yet not used code", range attributed regionally.

 

* NATO and other Military aircraft's 'sharing' the civil airspace use several code from a conventional table, like ''0300, or 0400 - NATO - CAOC 9 Exercises (activated by NOTAM)'' and ''3500 - NATO - Aircraft receiving a service from AEW aircraft''

 

 

While some code are use the same worldwide, like the emergency code, some other codes have a different regional meaning, like the special code '0000'

 

* - it is used by the "En route Control ARTCC" for aircraft's in cruise in their controlled airspace when ... their are no more non attributed / in current use ORCAM codes.

* - The Dep. of Transportation and the FAA have started to advocate, from 1918, the abandon of it's use going toward to prohibition of its use.
