Document-No: 03.2102.010.71e / Revision: 2.02
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. DEABC)
with no dashes, spaces/blanks or additional zeros, even if they are
included in the registration marking on the aircraft (tail number). While
entering the FID into the transponder the last remaining digits must be
filled with blanks.
The ICAO Flight Plan only specifies 7 characters for FID.
Funkwerk Avionics reserves 8 characters as stated in ED-
73B for further expansion of the flight plan.
The user shall only program 7 characters for FID.
4.1.5 Option
Ground-Switch
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.
With a connected ground switch (see section 3.6.1.2) the transponder
automatically changes into Standby mode once the gear touched the
ground. For this the Setup must be configured accordingly. For a detailed
description of the Setup progress, please refer to 4.2.1 Setup Steps.

Besides AA, AC and FID another important part of the Mode-S data is

be configured in the setup (see 4.2.1) and must contain one of the
following codes.
