AIC A 08/06. Use of Transponder Mode S in EKCH

(Replaces AIC A 07/06)

Copenhagen Airport, Kastrup (EKCH) has installed a surface

movement guidance and control system utilising transponder

mode S signals. The system is now operational.

Aircraft are asked to ensure that the transponders are able to op-

erate according to ICAO specifications when the aircraft is on the

ground (Annex 10, volume IV, 3.1.2.8.5.3 and 3.1.2.10.3.10).

Flight crew are required to select the assigned mode A (squawk)

code and activate the mode S transponder:

- from commencement of push-back or taxi, whichever comes

first:

- after landing, until the aircraft is fully parked on stand. The

transponder shall be switched off immediately after parking.

Flight crew of aircraft equipped with a mode S transponder that

has an aircraft identification feature should also select the aircraft

identification (item 7 of the ICAO flight plan) before activating

transponder.

Flight crews of aircraft not equipped with a mode S transponder

must squawk assigned SSR-code ONLY when instructed to line up

on the runway.
