1
The pilot intends to take-off
Immediately before, or during, taxiing
2
The pilot intends to enter a runway Immediately before entering a runway
3
The pilot is inbound
10 nm or earlier from the aerodrome,
commensuratewith aircraft
performance and pilotworkload, with
an estimates time of arrival (ETA) for
the aerodrome
4
The pilot is ready to join the circuit Immediately before joining the circuit
5
• The pilot intends to carry out a
straight-in approach; or
• join on base leg
On final approach at not less than 3 nm
from the threshold
Prior to joining on base
6
The pilot intends to fly through the
vicinity of, but not land at, a non-
towered aerodrome
When the aircraft enters the vicinity of
the aerodrome (ad defined)
Table 2: Circumstances/Broadcasts in the vicinity of non-towered aerodromes
Note 1: Some distances above refer to the runway threshold and others to
the aerodrome reference point (ARP). Pilots should be aware that a
global positioning system (GPS) indicationof 3nm from an aerodrome
may not be 3 nm to the runway threshold.
In addition:
• Listening to other pilot broadcasts increases situational awareness and
assists the sighting and avoidance of other aircraft;
• Where it is determined there is a potential for traffic conflict, radio
broadcasts should bemade as necessary to avoid the risk of a collisionor
an airprox event. A pilot should not be hesitant to call and clarify theother
aircraft’s position and intentions if there is any uncertainty; and
• It is essential tomaintain a diligent lookout becauseother trafficmay not
be able to communicate on the radio for various reasons—theymight
be tuned to thewrong frequency, selected thewrong radio, have a
microphone failure, or have the volume turneddown.
