1.3.2.
Except in the cases described above ( 7700 / 7600 / 7500) , the pilot shall:
1. select codes as instructed by the ATS unit; or
2. in the absence of ATS instructions related to code setting, select code 2000
3. when not receiving air traffic services, select code 7000 in order to improve the detection of
suitably equipped aircraft.
1.3.3 Frequency Monitoring Code
Pilots operating in Belgian class G airspace who are not receiving FIS, but are monitoring the COM
channel of Brussels FIC, should select Code 5101 if the aircraft is equipped with a Mode S
transponder.

ENR 1.7 ALTIMETER SETTING PROCEDURES
2.3 En-route
The cruising level at which a flight or a portion of a flight is to be conducted shall be expressed in terms
of flight level when operated above the transition altitude.
When flying in a controlled airspace associated with an aerodrome (TMA or CTR) at or below the
transition altitude, the aerodrome QNH value given by the relevant control unit shall be used for the
altimeter setting.
When flying outside controlled airspace at or below 4 500 FT AMSL, the altimeter shall be set to the
regional QNH given on pilot's request by Brussels FIC, Steenokkerzeel ATCC or by any ATC unit. The
regional QNH is the lowest of the QNH values for the following stations: EBAW, EBBE, EBBR, EBCI,
EBCV, EBFS, EBBL, EBFN, EBLG, ELLX, EBOS, EBSH and EBSP.
VFR flights conducted at or below 3 000 FT AGL do not have to maintain a semi-circular cruising level
and consequently are not compelled to use any particular altimeter setting. However, they are advised:
- to take into consideration, for terrain and obstacle clearance purpose, either the regional QNH
or the QNH value relevant to the area overflown (EBBR, ELLX, EBOS and EBSP) obtainable
from Brussels FIC or Steenokkerzeel ATCC;
- to take note that high speed low level military flights, having a flight visibility less than 5 KM, are
mandatory conducted under IFR and are therefore maintaining semi-circular IFR cruising
altitudes based on the regional QNH.
