Hi Shawn
This is direct from the Belgium AIP I hope it helps.
ENR 1.2 Visual Flight Rules
1 MINIMA FOR VISIBILITY AND DISTANCE FROM CLOUDS
Except when operating as a special VFR FLT, VFR FLTs shall be conducted so that the ACFT is flown in conditions of visibility and distance from clouds equal to or greater than those specified in the following table.
Airspace class A* B C D E F G
Above 900 m (3 000 ft ) AMSL or above 300 m (1 000 ft ) above terrain, whichever is the higher At and below 900 m (3 000 ft ) AMSL or 300 m (1 000 ft ) above terrain, whichever is higher
Distance from clouds 1 500 m horizontally
300 m (1 000 ft ) vertically
Clear of clouds and in sight of the surface
Flight visibility 8 km at and above FL 100
5 km below FL 100
5 km**
(*) The VMC minima in Class A airspace are included for guidance to pilots and do not imply acceptance of VFR FLTs in Class A airspace.
(**) In Belgium
Flight visibilities of at least 1500 m are permitted between 30 MIN before SR and 30 MIN after SS for FLTs operating either:
at 250 kt IAS or less so that, in the prevailing visibility, adequate opportunity exists to observe other traffic or any OBSTs in time to avoid collision.
in circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low volume traffic and for aerial work at low levels.
Flight visibilities of at least 1500 m are permitted to ACFT operating in the AD traffic circuit (local FLT).
Helicopters may be permitted to operate with a flight visibility of at least 800 m, provided that they remain below 300 m (1000 ft) AGL
between 30 MIN before SR and 30 MIN after SS
if manoeuvred at a speed that will give adequate opportunity to observe other traffic or any OBSTs in time to avoid collision.
(**) In the Grand Duchy of Luxembourg
Flight visibilities of at least 1 500 m are permitted between 30 MIN before SR and 30 MIN after SS for FLTs operating either:
at 140 kt IAS or less that, in the prevailing visibility, will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision
in circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low volume traffic and for aerial work at low levels.
Helicopters may be permitted to operate with a flight visibility of at least 800 m, if manoeuvred at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision.
Lighter-than-air ACFT are permitted to operate with a flight visibility of at least 800 m provided that they remain below 300 m (1 000 ft ) AGL.
2 VFR FLIGHTS IN CTR
Except when a CLR is obtained from an ATC unit, VFR FLTs shall neither take off nor land at an AD within a CTR, nor enter a traffic pattern when either:
the ceiling is less than 450 m (1500 ft )
the ground visibility is less than 5 km.
3 VFR FLIGHT RESTRICTIONS
VFR FLTs shall not be operated:
at night
In Belgium: between 30 MIN after SSand 30 MINbefore SR, unless authorized by the Director General of the CAA or under the conditions described in 8.1.a below.
Note 1: The hours of apparent SR and SS at Uccle (see GEN 2.7 ) are taken into account for the calculation of these periods.
Note 2: State ACFT (MIL ACFT and ACFT used by State services such as police and customs) may fly VFR at night.
In the Grand Duchy of Luxembourg: between 30 MIN after SS and 30 MIN before SR, unless otherwise authorized by the Minister of Transport (see FLTs at night in the G.D. of Luxembourg).
above FL 190
at transonic and supersonic speeds.
8.1 VFR flights at night
In Belgium
Balloons, gliders, DPM and ULM exempted, VFR FLTs at night are authorized from and to agreed airfields approved for night OPS:
Within controlled airspace:
in respect of the CLRs provided by the involved ATC unit
with transponder equipped ACFT
Outside controlled airspace:
between 1 000 ft and 4500 ft AMSL on the regional QNH at a level in accordance with the semi-circular VFR cruising table above 3 000 ft AGL
in bilateral radio contact with the unit providing FIS
only with transponder equipped ACFT
Note 1: VFR FLTs at night within the AD traffic circuit are not authorized at EBBR.
Note 2: At non-controlled ADs, VFR FLTs may be operated locally at night within the AD traffic circuit when continuously in sight of the control tower or its substitute and when authorized by the Director General of the CAA or by the official delegated authority.
Note 3: In all cases, the submission of a flight plan is required.
Note 4: VFR FLTs at night shall be conducted so that the ACFT (helicopters exempted) is flown in MET conditions equal to or greater than:
flight visibility of 5 km
ceiling of 450 m (1 500 ft).
Note 5: Helicopters may be permitted to operate with a FLT visibility of at least 800 m, if manoeuvred at a speed that will give adequate opportunity to observe other traffic or OBST in time to avoid collision.
Note 6: Except for LDG and TKOF, the MNM LVLfor VFR at night between 2200 and 0459 is FL 50. This rule is not applicable for helicopters (see ENR 1.1, Noise abatement provision in Belgium).
Note 7: SAR, police and customs FLTs on real live missions may deviate from prescribed conditions but are requested to submit a flight plan as soon as possible and to adhere to the instructions issued by the appropriate ATS.
In the Grand Duchy of Luxembourg
VFR FLTs at night may be operated in the airspace over the Luxembourg territory:
in the CTR
in the TMA up to FL 95 MAX
8.3 Special VFR flights
When the ground visibility is not less than 1500 m (800 m for helicopters, if manoeuvred at a speed that will give adequate opportunity to observe any obstructions in time to avoid collision) and when traffic conditions permit, special VFR FLTs may be authorized within a CTR subject to the provisions specified hereafter and those relating to special VFR FLTs at certain ADs (see Part 3 Aerodromes).
Between 30 MIN before SR and 30 MIN after SS.
Requests for such authorization shall be handled individually.
Special VFR FLTs shall be operated clear of clouds and in sight of the ground or water.
Separation shall be effected:
between all special VFR FLTs and
between such FLTs and all IFR FLTs.
in Class G airspace up to 2 000 ft AMSL MAX.
