Military Aerodrome Traffic Zones (MATZ) are established at a number of locations – follow the link on page 8 for details. The purpose of a MATZ is to provide a volume of airspace within which increased protection may be given to aircraft in the critical stages of circuit, approach and climb-out. Normally, these zones comprise:
(a)  the airspace within 5nm of the mid-point of the longest Runway, from the surface to 3000ft above aerodrome level;
(b)  the airspace within a ‘stub’ (or at some aerodromes 2 stubs) projected from the above airspace having a length of 5nm along its centre-line, aligned with a selected final approach path, and a width of 4nm (2nm either side of the centre-line), from 1000ft above aerodrome level to 3000ft above aerodrome level.
An Aerodrome Traffic Zones (ATZ) exists within most MATZ and is based upon the same reference points as listed in the table below. Although the recognition of a MATZ by civil pilots is not mandatory, they are encouraged to do so. Civil pilots, however, must comply with the provisions of the current UK Rules of the Air Regulations in respect of the ATZ. The notified hours of operation of an ATZ may vary from the notified hours of watch of a MATZ.
 
 
MATZ Penetration Procedures for Civil Aircraft
 
A MATZ Penetration Service for the provision of increased protection of VHF RTF equipped civil aircraft is available from the controlling aerodrome of said MATZ – pilots wishing to penetrate a MATZ are requested to observe the following procedures:
 
(a) when 15nm or 5 min flying time from the zone boundary, whichever is the greater, establish two-way RTF communication with the controlling aerodrome on the appropriate frequency using the following phraseology: 
 
‘.........(controlling aerodrome), this is.......(aircraft callsign), request MATZ penetration’.
 
(b)  when the call is acknowledged and the ATS Unit requests ‘pass your message’, pass the following information:
 
. Call Sign/Type

 
. Departure Point and Destination

 
. Present Position

 
. Level

 
. Additional Details/Intentions (e.g. Flight Rules, next route point)

 
(c)  comply with any instructions issued by the controller.
 
(d)  maintain a listening watch on the allocated RTF frequency until the aircraft is clear of the MATZ.
 
(e)  advise the controller when the aircraft is clear of the MATZ.
 
Flight conditions are not required unless requested by the controller.
 
 
The military ATSU providing the MATZ Penetration Service will normally continue with the service that the aircraft was previously receiving. In the interests of flight safety and good airmanship, it is strongly recommended that all pilots not previously receiving an ATS obtain a MATZ penetration 'approval' from the MATZ operating authority, prior to entering a MATZ. It is recognized that most MATZ crossing/penetration 'approvals' will be obtained via RT by pilots in receipt of an ATSOCAS; however, it should be possible for a pilot to request a MATZ crossing/penetration 'approval' without the use of radio (ie by prior agreement via telephone). In accordance with Class G airspace classification and the rules of ATSOCAS, pilots are ultimately responsible for maintaining their own separation against other airspace users within the MATZ. Occasionally, a change in service may need to be negotiated in order to facilitate the MATZ crossing and the advisory information and/or instructions passed by the ATSU will accord with the service being provided. In the event of no radar being available, a procedural service, and/or routeing instructions, might be provided to aircraft penetrating the MATZ
