To enable vertical separation to be applied, all aircraft will be given an altimeter setting to use within the MATZ. Normally this will be the aerodrome QFE, with the exception of the following:
(a) Within the Odiham MATZ the transit pressure setting will be the Farnborough QNH.
(b) Within the Warton MATZ the setting will be the Warton QNH.
(c) Within the Lakenheath/Mildenhall MATZ the setting will be the Lakenheath QNH.
(d) In the case of overlapping MATZs, the altimeter setting to be used will be the QFE of the higher or highest aerodrome of the CMATZ. This will be passed as the 'Clutch QFE'. Whilst every effort will be made to ensure the safe separation of aircraft complying with these procedures, since compliance is not compulsory, some civil aircraft within the MATZ may not be known to the controller. Pilots should therefore keep a good lookout at all times. Terrain clearance will be the responsibility of pilots.
Availability of the MATZ Penetration Service
A MATZ penetration service will be available during the published hours of watch of the respective units. However, as many units are often open for flying outside normal operating hours, pilots should call for the penetration service irrespective of the hours of watch published. If, outside normal operating hours, no reply is received after two consecutive calls, pilots are advised to proceed with caution. Information on the operation of aerodromes outside their normal operating hours may be obtained by telephone from the appropriate Military Air Traffic Control Centre:
North of N5430 - Telephone: Scottish ACC (MIL) 01292-479800, Ext 6703/4
South of N5430 - Telephone: London ACC (MIL) 01895-426150.
Reference to specific MATZs can be found in AIP at section ENR 2.2. See also the MATZ coverage Diagram at section ENR 6.2.
5. Airspace subject to Flight Restrictions or Hazards
Prohibited Areas*
A Prohibited Area is an area of airspace of defined dimensions within which the flight of aircraft is prohibited.
Restricted Areas*
A Restricted Area is an area of airspace of defined dimensions within which the flight of aircraft is restricted in accordance with certain specified conditions.
Danger Areas*
A Danger Area is an area of airspace which has been notified as such within which activities dangerous to the flight of aircraft may take place or exist at such times as may be notified.
