Visual Circuit Reporting Procedures
 
In order that maximum use may be made of aerodromes for the purpose of landing and taking off, it is essential that pilots accurately report their position in the circuit (see Flight in Vicinity of an Aerodrome - Note 2 overleaf).
 
Position reports are to be made as follows:
 
(a)  Downwind - aircraft are to report ‘Downwind’ when abeam the upwind end of the runway.
 
(b) Base Leg - Aircraft are to report ‘Base Leg’, if requested by ATC, immediately on completion of the turn onto base leg.
 
(c)  Final - Aircraft are to report ‘Final’ after the completion of the turn onto final approach and when at a range of not more than 4nm from the approach end of the runway.
 
(d) Long Final - Aircraft flying a final approach of a greater length than 4nm are to report ‘Long Final’ when beyond that range and ‘Final’ when a range of 4nm is reached. Aircraft flying a straight-in approach are to report ‘Long Final’ at 8nm from the approach end of the runway and ‘Final’ when a range of 4nm is reached.
 
At grass aerodromes, the area to be used for landing should be regarded as the runway for the purposes of reporting.
 
 
‘Permit to Fly’ Aircraft
 
Aircraft operating on a ‘Permit to Fly’ (eg ‘home-built’ aircraft not subject to a regular ‘Certificate of Airworthiness’) shall not be flown over any assembly of persons or over any congested area of a city, town or settlement
 
 
Flight within Aerodrome Traffic Zones
 
The following paragraphs apply to aerodromes described in column 1 of the following table and notified for the purposes of Rule 45 of the UK Rules of the Air Regulations (see below) and throughout the period specified in column 2.

Rule 45 states that an aircraft shall not fly, take-off or land within the Aerodrome Traffic Zone to which this paragraph applies unless the commander of the aircraft has obtained the permission of the air traffic control unit at the aerodrome or, where there is no air traffic control unit, has obtained from the aerodrome flight information service unit at that aerodrome, information to enable the flight within the zone to be conducted with safety or, where there is no air traffic control unit nor aerodrome flight information service unit, has obtained information from the air/ground radio station at that aerodrome to enable the flight to be conducted with safety.
