General 4 Control of Traffic Flashcards
What should an ATC clearance include?
ATC clearances shall include
(1) Aircraft identification as shown in the flight plan
(2) Clearance limit
(3) Route
(4) Level Required
(5) Any Necessary Instructions
What are the ways that a clearance limit can be specified?
A clearance limit shall be specified by naming
(1) an aerodrome;
(2) a reporting point; or
(3) a controlled or advisory airspace boundary.
When shall an aircraft be cleared for the whole route all the way to the aerodrome of first intended landing?
(1) it has planned to remain within controlled or advisory airspace throughout the flight; and
(2) there is reasonable assurance that prior co-ordination will be effected ahead of the passage of the aircraft.
What is the structure of a conditional clearance?
(1) Callsign of the aircraft or vehicle being given the clearance
(2) The condition
(3) The clearance
(4) A brief reiteration of the condition
Who has priority, an aircraft at a level or an aircraft requesting that level?
An aircraft already occupying a level will normally have priority
How should Flight Levels ordinarily be assigned?
In accordance with the table of cruising levels
What should an ATCO do if they have reason to believe that a planned flight is liable to endanger life or involve a breach of legislation?
(1) Warn the pilot of the hazardous condition or infringement and obtain acknowledgement
(2) For infringement of legislation, warn the pilot that if they take-off, it will be reported
(3) If pilot insists on taking off, then when traffic permits, state that there no traffic reasons to restrict take-off
(4) Record the warning and any comment made by the pilot in the ATC Watch Log
What are the flight priorities?
A
Emergency Aircraft
Police Emergency
Medical/SAR when safety of life involved
B
SAR/other humanitarian reasons
Post-accident flight checks
Normal Police operation flights
C
Royal Flights
Flights carrying visiting Heads of State
D
Heads of Government or very senior Government Ministers
E
Time or Weather Critical Calibration Flights
Repositioning HEMS flights
Other Flights authorised by CAA
NORMAL FLIGHTS
Z
Training, Non-Standard, Other
If an aircraft declares ‘Minimum Fuel’ should they be given priority?
ATCOs are only required to give priority if an aircraft declares MAYDAY FUEL
If a pilot states there is a medical emergency onboard should they be given priority?
ATCOs are only required to give priority if they declare an emergency, and so ATCOs should ask if they are declaring an emergency.
Where does transfer of control normally take place?
(1) At an agreed reporting point;
(2) On an estimate for an FIR boundary;
(3) At or passing an agreed level; or
(4) Climbing/Descending to an agreed level when separation exists
Why might transfer of communication happen before transfer of control?
So that control instructions which become effective later can be issued.
What are the parameters for Civil and Military formation flights?
Civil
0.5NM and 100ft
Military
1NM and 100ft
If a Police Helicopter is flying Category B, can the ATCO change its parameters?
A Police Helicopter B is a normal operational priority and the PIC will expect ATCOs to issue minor changes to the flight parameters in order to not cause a delay to other traffic
If a Helimed is flying Category E, is it afforded priority?
Yes. A Helimed Category E is afforded priority over other flights.
