Military aerodrome traffic zones have been established as detailed by the UK AIS and are listed in ENR 6-17.
[1] They provide protection to military aircraft traffic in the critical stages of circuit, landing and takeoff.
In the centre of the MATZ is an aerodrome traffic zone, ATZ.
The MATZ airspace has no legal recognised status under the UK Air Navigation Order (ANO) for civil pilots and no prior permission is required to enter it.
For safety and good airmanship, pilots are strongly encouraged to obtain 2-way radio communications with the controlling air traffic service before transitting the airspace.
