Separation and Traffic Services Flashcards
Below what altitude may pilots be assigned responsibility for separation? What is the pilot’s responsibility?
You may only assign responsibility for visual separation to a pilot when:
a) aircraft are operating at or below 10 000 FT; and
b) the pilot of one aircraft:
i) reports sighting the other aircraft; and
ii) accepts responsibility to maintain visual separation with, pass behind or follow that aircraft.
When applying visual separation what must you do if there is doubt as to the pilot’s ability to keep the other aircraft in sight?
Issue an alternative instruction to provide separation if there is any doubt as to the pilot’s ability to keep the other aircraft in sight or maintain separation.
List four possible limitations to a pilot’s ability to comply with instructions?
a) the field of vision from the cockpit;
b) the contrast of aircraft with the background against which it will appear;
c) glare of the sun; and
d) restrictions on atmospheric visibility which may not be currently apparent to the pilot e.g. loss of forward visibility following descent into a haze layer.
What traffic information should be given to aircraft when passing Directed Traffic Information?
a) aircraft identification;
b) type, and description if unfamiliar;
c) position information;
d) estimated time of passing or closest point of approach;
e) direction of flight or route of aircraft;
f) level;
g) intentions of the pilot, such as:
i) initial departure track and intended cruising level; and
ii) inbound track or direction, level and next estimate; and
h) advice that an aircraft is not yet on the appropriate frequency.
What is the definition of a “State Aircraft”?
An aircraft of any part of the Defence Force (including any aircraft that is commanded by a member of that force in the course of his/her duties as such a member) and aircraft used in the military, Customs, or Police services of a foreign country
Identify if the following levels should be
assigned to aircraft travelling east or west.
FL120
A090
FL230
FL430
FL450
A080
FL120 West
A090 East
FL230 East
FL430 West
FL450 East
A080 West
Which Flight Levels are not available when the Area QNH is 993 HPA?
FL110, FL115
At which altitude must aircraft operating in the Australian FIR change to QNH 1013.2 HPA?
A100
(10,000ft)
What circumstances would warrant the issue of a SAFETY ALERT?
Unless the pilot has advised that action is being taken to resolve the situation or that the other aircraft is in sight, issue a safety alert prefixed by the phrase ‘SAFETY ALERT’ when you become aware that an aircraft is in a situation that places it in unsafe proximity to:
a) terrain;
b) obstruction;
c) active restricted or prohibited areas; or
d) other aircraft.
When may you discontinue issuing a SAFETY ALERT?
You may discontinue issuing further safety alerts or traffic avoidance advice when the pilot advises action is being taken to resolve the situation or has reported the other aircraft in sight.
In what classes of airspace may safety alerts be issued?
All classes
When is the prefix “Suggest” used when issuing collision avoidance advice for aircraft in close proximity?
Prefix advice to turn or change level with ‘SUGGEST’ unless the advice is for controlled flights with reference to other controlled flights
What is expected of the controller upon becoming aware of information such that it would be reasonable to conclude that an unsafe situation has occurred, or may occur?
Provide a Safety Alert
To which organisation must messages from Customs Surveillance Flights be passed?
AMSOC, Australian Maritime Security Operations Centre
What is the name of the message sent to AMSOC?
SURVEREP, Surveillance Report
What is a holding procedure?
A predetermined manoeuvre which keeps an aircraft within a specified airspace while awaiting further clearance.
What is a holding fix?
A geographic location that serves as a reference for a holding procedure.
