Q

Approach radar controller will be responsible for

A

Obtaining l/d clearance from a/d control

Forwarding this clearance onto the a/c - if not received by the aerodrome by 2nm - carry out a missed approach

16
Q

Info to a/c prior to entering the traffic pattern/commencing an aprch to l/d

A

R/y in use

Wind speed and direction

QNH

17
Q

When are a/c transferred from aprch control to a/ control

A

In the vicinity of the aerodrome

18
Q

Aprch control service are found in

A

A/d in CTRs where met conditions are IMC or the criteria for VMC t/o cannot be met

19
Q

Aprch control in an aprch control service is responsible for

A

Giving clearance for t/o

Obtaining clearance to l/d from aerodrome controller for IFR flights carrying out low vis approaches

20
Q

Delays - control of a/c

A

ATC advise operators when the delay exceeds 30mins

21
Q

IFR flight will not be cleared for an initial approach below the min alt unless

A

A/c reports that the a/d is in sight

Pilot reports passing an appropriate point defined by a nav aid

A/c is conducting a visual aprch

A/c posn has been positively determined by radar

22
Q

An IFR flight can be cleared fora visual aprch if

A

Pilot can maintain visual ref with the terrain

Ceiling is at or above the approved aprch level
Or
Pilot reports at anytime during the inst approach that the met conditions would allow a visual aprch and l/d - need not be Vmc

23
Q

Speed control will cease when the a/c

A

Has passed 4nm from l/d

24
Q

Unfamiliar procedures

A

ATC can specify the whole procedure - straight in aprch - only the FAT and the missed aprch will be passed

25
Q

Separation between holding a/c and enroute a/c without lateral separation

A

5mins flying time of the holding area

26
Q

EAT and who is is applicable to

A

Time the a/c will be expected to leave the hold and commence the aprch

Applicable to a/c who have been subjected to a delay of 10mins or more

27
Q

EAT must be sent

A

Expeditiously to a/c expected to hold for 30mins or more

Revised EAT is sent when it differed by 5 mins or more from previous EAT

28
Q

Info for arriving a/c on the final aprch

A

Sig changes in mean surface wind speed and direction

Windshear

Vis and RVR

29
Q

Air traffic advisory service

A

Provided within class F
Ensures the separation of IFR traffic
Advisory routes instead of airways (ADRs)
Clearances not issued - only advice
Traffic to cross an ADR at 90* at the appropriate FL
All flights receive FIS if requested

30
Q

Emergency descent

A

ATCU will warn the a/c in the vicinity

A/c will broadcast altitude at intervals

Maintain HDG and speed (current clearance) unless threatened by danger/ instructed by ATC

31
Q

Fuel jettison is not allowed

A

Below 6000

Over towns

When CB activity is reported/expected

In CAS - need to inform ATCU

32
Q

Strayed/unindent a/c

A

A/c has deviated sig from track/ reports it is lost
