If proposing to fly into a control area from an aerodrome located so close
to theentry point thatmaking a full position report beforeentry is not
practicable, a clearance should be requested:
• at aconvenient timebeforeentering the runway for take-off at anaerodrome
wherecommunicationcan readilybeestablishedbefore take-off; or
• after take-off, if not available or obtainablebefore take-off, provided that
the aircraft does not enter the control area until cleared.
If landing at an aerodromewith the intention of departing for a control area
shortly after landing, any revision of notified details relevant to the clearance,
includingEstimatedTime of Departure (ETD), shouldbe advised toATC, and a
clearance requested before landing.
Clearances provided to pilotsmay include a ‘
CLEARANCEVOIDTIME
’.
Where a void time is specified, the clearance is valid only if the flight enters
controlled airspace in accordancewith the clearance at or before that time.
Pilots should submit details required for flight in controlled airspace at least
30minutes before theexpected time of entry. Flight details submittedwith
less than 30minutes notificationwill beprocessedon a ‘controllerworkload
permitting’ basis, andmay be subject to delay.
AIRWAYSCLEARANCE
A pilot in commandmust request an airways clearance:
• before entering controlled airspace,
• on the clearancedelivery frequency, preferably immediately before
starting engines, otherwise as soon as possible thereafter; or
• where a clearance delivery frequency is not available, beforeentering the
departure runway.
Airways clearances normally contain the following items:
• aircraft identification;
• destination, area of operation, position or clearance limit;
• route of the flight;
