(b) Temporary Control Areas. Temporary Control Areas will be established to meet the specific requirements of a Royal Flight. The lateral and vertical limits, the duration and the controlling authority of such areas will be promulgated via NOTAM. The controlling authority will be the appropriate civil ATCC.
(c) Permanent Control Zones and Areas. The controlling authority will be the designated controlling authority for the Permanent Zone or Area and the duration will be as laid down in the sub paras (a) and (b) above. Where an airfield has its own Control Zone, then the requirement to establish a Temporary Control Zone of the dimensions specified in para (a) above may be waived.
(d) Temporary Controlled Airways. Temporary Controlled Airways will be established to join temporary or permanent Control Zones or Control Areas, as appropriate, for 15 minutes before ETD at the departure airfield until 30 minutes after ETA at the destination. The lateral dimensions of such airways will be 5nm each side of the
intended track of the Royal Flight and vertical limits will be designated. The controlling authority will be the appropriate civil ATCC.
A Temporary Control Zone or Area may be cancelled at the discretion of the Military Commander or Civil ATC Supervisor, as appropriate, when the Royal aircraft has left the zone or area and is established en-route in a Temporary Controlled Airway, permanent Class A/C airspace, or has landed.
Training Flights, including parachute training flights, by any member of The Royal Family planned and carried out under VFR or IFR, and under the control of an ATCRU or aerodrome radar, will normally be classified as Royal Flights. CAS-T, if required, will be established as agreed by the aircraft operating organisation and the Directorate Airspace Policy, Airspace Utilisation Section.
