AIRMANSHIP

Theuseof ‘standard’ aerodrome traffic circuit procedures and radiobroadcast

procedures for all radio-equipped aircraft as described in theAIP is strongly

recommended at all non-towered aerodromes.

Pilots areencouraged to turn on external lights, wherefitted, when in the

vicinity of a non-towered aerodrome, and until the aircraft has landed and is

clear of all runways.

Transponders can bedetected by aircraft equippedwithAirborneCollision

AvoidanceSystem (ACAS) or TrafficCollisionAvoidanceSystem (TCAS),

allowing them to ‘see’ other aircraft and takeevasive action. Pilots of

transponder-equipped aircraft should at all times ensure their transponder

is switched toON/ALT (ModeC), includingwhen operating in the vicinity

of a non- towered aerodrome. In the event of a radio failure, it is important

that pilots select code 7600 andModeC on their transponders and continue

squawking.

So as not to impede commercial aviation, pilots flying recreational or sport

aircraft for their own enjoyment, or pilots flyinggeneral aviation (GA) aircraft

for their own leisure, should consider givingway to aircraft being used for

‘commerce’ provided that the inconvenience to their ownoperation is not

great and it can be done safely. Operators of commercial aircraft should never

expect a giveway offer to be assumed or automatic. Any offer to giveway

must be explicit and its acceptance acknowledged.

CIRCUITPROCEDURES

StandardCircuit. The standard aerodrome traffic circuit facilitates theorderly

flow of traffic, and is normally a left circuit patternwith all turns to the left.

When arriving at an aerodrome to land, the standard circuitwill normally

be joined on the upwind, crosswind or downwind legs, at or beforemid-

downwind. Landings and take-offs should be accomplishedon an operational

runwaymost closely aligned into thewind (the active runway).

If a secondary runway is being used, pilots using a secondary runway should

avoid impeding the flow of traffic that is using the active runway.
