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.
