2.3   Navigation Routes 15W TPT

A Terrain Avoidance Plan (TAP) will be applied for each night flight including:

• Imposed night flight altitudes:
  • Along predetermined routes using NVG: minimum altitude of 500FT above the highest obstacle within a radiusof 1NM of the aircraft as indicated on the Obstacle sheets per leg, avoiding populated areas.
  • Along predetermined routes without NVG or outside predetermined routes: minimum altitude of 1000FT above the highest obstacle within a radius of 5KM of the aircraft as indicated on the Obstacle sheets per leg.
  • Above the lateral limits of the LFA Ardennes: Minimum Safety Height to be respected is 500FT above the highest obstacle within a radius of 1NM of the aircraft.
• Obstacle sheets per respective route;
• Thorough map study;
• Emergency Safety Altitude (ESA).

The proposed routes will be flown by daylight on a yearly basis in order to update the obstacle clearance sheet.

In order to provide awareness, all night flights for the next week will be coordinated and announced by the night flight message sent by Steenokkerzeel ATCC each THU for the next week. Also, a Flight Plan needs to be filed for any night flight not later than 1100 (1000) on the day of flight.:

AMC will:

• provide Brussels FIC with details on MIL low level night flights activities;
• coordinate night flights between helicopters and fixed wing aircraft.

Aircraft which have not been allocated a specific route segment shall avoid these night low flying routes, unless the respective route segment is not activated or the aircraft is under RIS/RC.

If the pilot can not maintain the enroute altitude for technical or other reasons, he shall assume the ESA, squawk A/7700 and request immediate ATC assistance.

Only pre-planned deviations will be allowed:

• For planned deviations of the routes and corridors an appropriate advance request shall be made to Steenokkerzeel ATCC not later than 24 HR prior take-off. All deviations are subject to approval of Steenokkerzeel ATCC;
• Upon instruction of Steenokkerzeel ATCC, the proposed TAP shall be aborted and the flight shall be continued at the enroute altitude, ESA or the allocated flight altitude depending on the instructions received.

The 15W Navigation Routes are depicted on the chart in ENR 6-ENRC.05e.

2.4   NVG Link Routes Belgian Military Helicopters

A Terrain Avoidance Plan (TAP) will be applied for each night flight including:

• Imposed Night Flight altitudes:
  • Along predetermined routes using NVG: minimum altitude of 200FT above the highest obstacle within a radiusof 1KM of the aircraft as indicated on the Obstacle sheets per leg.
  • Along predetermined routes without NVG or outside predetermined routes: minimum altitude of 500FT above the highest obstacle within a radius of 3KM of the aircraft as indicated on the Obstacle sheets per leg.
  • In the HTAs: at an altitude between GND and 500FT AGL, adapting speed and height in function of the contours and cover of the ground.

• Obstacle sheets per respective route
• Thorough map study
• Minimum Safe Altitude (MSA)

The proposed routes will be flown by daylight on a yearly basis in order to update the Obstacle clearance sheet.

In order to provide awareness, all night flights will be announced by the night flight message sent by Steenokkerzeel ATCC each Thursday for the next week. Also, a Flight Plan needs to be filed for any night flight not later than 1100 (1000) on the day of flight. AMC will:

• Provide Brussels FIC with details on MIL low level night flights activities
• Coordinate night flights between helicopters and fixed wing aircraft.

aircraft which have not been allocated a specific route segment shall avoid these night low flying routes, unless the respective route segment is not activated or the aircraft is under RIS/RC.

If the pilot cannot maintain the en-route altitude for technical or other reasons, he shall assume the MSA, squawk A/7700 and request immediate ATC assistance.

Only pre-planned deviations will be allowed:

• For planned deviations of the routes and corridors an appropriate advance request shall be made to COMOPS AIR&SPACE not later than 24HR prior take-off. All deviations are subject to approval by COMOPS AIR&SPACE.

• Upon instruction of Steenokkerzeel ATCC, the proposed TAP shall be aborted and the flight shall be continued at the en-route altitude, ESA or the allocated flight altitude depending on the instructions received.

The Belgian Military Helicopter NVG Routes are depicted on the chart in ENR 6-ENRC.05d.

To allow maximum training value and to reduce repetitive overflights of the same route, a set of reporting points is established. The link routes are any acceptable combination of routes between those published points. Full priority will be given to night flights planned to follow route BENE TWO (see § 2.1.1 above).

For safety and de-confliction reasons only the following route based on a set combination of points can be flown Night VFR assisted by NVG:

All routes may be flown clockwise and counter-clockwise.
