Communications in CTA and Controlled Aerodromes Flashcards
Broadly when do pilots require a clearance?
- Operating in class A, C or D airspace
- Operating IFR in Class E airspace
- Operating on the manoeuvring area at a controlled aerodrome
What is an airways clearance?
A clearance issued by ATC to operate in controlled airspace along a designated track or route at a specified level to a specified point or flight-planned destination
When must pilots in command request an airways clearance?
- on the clearance delivery frequency, preferably immediately before starting engines, otherwise as soon as possible thereafter; or
- where a clearance delivery frequency is not available, before entering the departure runway; and
- before entering controlled airspace.
What must be included when issuing a clearance?
a) aircraft identification;
b) destination, area of operation, position or clearance limit;
c) route of flight; and
d) assigned level, except when this element is included in the SID description.
You may include any additional instructions such as:
a) a level restriction;
b) departure type for IFR flights;
c) SSR code; and
d) frequency requirements.
Do not use the phrase FLIGHT PLANNED ROUTE when _____________
reclearing an aircraft
You may use the phrase FLIGHT PLANNED ROUTE when?
In an initial airways clearance to describe any route or portion of route that is identical to that filed in the flight notification after providing sufficient route details to definitely establish the aircraft on its route.
When an airways clearance is amended en route, prefix the route and/or level information with the term ‘_________________’ to indicate to the pilot that a change has been made to the previous clearance and this new clearance supersedes the previous clearance or part thereof.
RECLEARED
A clearance, and its amendments during a flight only apply ______________
(list all)
- to the first point at which the aircraft leaves controlled airspace;
- to the first landing point if the flight is wholly within controlled airspace;
- to the clearance limit if issued;
- until the expiration of a clearance void time; or
- until cancelled by a controller.
A taxi clearance regulates movement _______________
on the manoeuvring area.
When will ATC provide clearance to take-off?
When the below are true.
- the aircraft is at or approaching the runway in use;
- the traffic situation permits;
- the aircraft has reported ‘READY’;
- a visual check of the take-off path has been completed;
- no obstructions or collision risk exists; and
- there is reasonable assurance that the required separation will exist when the aircraft commences take-off.
When will the ADC provide clearance to land?
When the below are true
- the aircraft has commenced final approach of a straight-in instrument approach or has been sighted by the tower controller
—– on the late downwind leg of the circuit pattern;
—– on base leg; or
—– on final in the case of a straight-in visual approach; - a visual check of the landing path has been completed; and
- no obstructions or collision risk exists.
A clearance to land also authorises a pilot to ______________
Go-around or carry out a missed approach
Clearance to change level must be prefixed with what?
CLIMB or DESCEND as appropriate
What do aircraft descending out of controlled airspace into a non-controlled aerodrome require?
Clearance to leave controlled airspace
A traffic statement
Area QNH when descending from levels above the transition altitude
When a clearance is not available, what is the standard phrase for ATC to use?
CLEARANCE NOT AVAILABLE, REMAIN OUTSIDE CLASS
(AIRSPACE CLASS) AIRSPACE
