Airspace of defined dimensions designated for air combat training within which high energy manoeuvres are regularly practised by formations of aircraft. Pilots of aircraft unable to avoid these areas should keep a good look-out and are strongly advised to make use of a radar service. Autonomous operations are only permitted within ATAs above FL 195 when the overlying TRA is active.
*Reference to specific AIAAs & ATAs can be found in AIP at ENR section 5.2.
Gliders
Certain of the airspace rules and regulations outlined in this guide either do not apply to gliders or are applied differently. In particular:
(a) Airways (Class A). Although VFR flight is not permitted in Class A Airways, gliders are exempt from this requirement if the airway is notified for the purpose of the UK Air Navigation Order Rule 18. Presently this arrangement is extant in Airways P600 and B226 for flights that comply with the conditions detailed in a Letter of Agreement between Scottish ACC and the BGA, and the glider pilot has received a briefing within the previous 12 months. In particular a glider may cross-designated corridors within Airways P600 and B226 without complying with the normal requirements for operation in Class A airspace. In particular:
. An ATC clearance is required;
. the crossing is carried out in VMC by day (for the purpose of this paragraph the VMC minimum is to be 8 km visibility, 1500 m horizontal and 1000ft vertical from cloud);
. the glider pilot is responsible for maintaining VFR separation from other gliders crossing the airways.
(b) Class C Airspace. See UK AIP ENR for details of Class C airspace for gliders above FL195
(c) Class D Control Zones/Areas. Gliders require an ATC clearance to cross Class D Airspace. Arrangements exist between some Class D airspace operating authorities and local gliding clubs whereby gliders are permitted access to specific portions of airspace under agreed procedures without having to communicate with ATC. Under these circumstances arrangements and procedures are published in the affected ATC unit and gliding club operating procedures.
Communications
Gliders are required to carry VHF RTF equipment to access Class A, Class C and most Class D Airspace, (under specific arrangements RTF equipment may not be required for access to Class D Airspace).
