3.1.4 Flight Identification (FID)

ICAO Document “8168-OPS/611 Volume I (Procedures for Air

Navigation Services)” requires that flight crews of aircraft equipped with

Mode S shall set the flight identification (FID) into the transponder to

ensure that the correlation between flight plan and radar data will work

automatically.

FID setting is required to correspond to the aircraft identification that has

been (correctly!) specified at item 7 of the ICAO flight plan:

• seven characters maximum, left-aligned, no additional zeros,

dashes or spaces

For an aircraft using a company call sign, the Flight-ID consists of the

ICAO three-letter designator for the aircraft operator, followed by an

identification code, e.g. KLM511, BAW213, JTR25.

If no company call sign is used or no flight plan is filed, the default FID to

be set consists of the registration marking of the aircraft (e.g. GXXXX,

DEABC) with no dashes, spaces or additional zeros, even if they are

included in the registration marking on the aircraft (tail number).

The ICAO Flight Plan only specifies 7 characters as FID.

Filser reserves 8 characters as stated in ED-73B for further

expansion of the flight plan.

The user shall only program 7 characters for FID.

3.1.5 Ground Switch Connection

If a ground switch is connected (and declared in the configuration!), the

transponder is able to acknowledge on-ground and in-flight state. In on-

ground state, stand-by mode is activated.
