Control Of A/c

Question 1

4 types of radar service

Answer 1

Radar control - controlled enroute a/c

Approach radar - for arriving and departing controlled traffic

Radar vectoring - to avoid danger areas. Intercept ILS etc

PAR and SRA - instrument approach systems

Question 2

Radar ident other methods

Answer 2

Turn through 30* or more from coarse then return

Positive handover(transfer) from a radar controller who had previously ident the a/c

Geog location, lat and long, geo ref posn, relative to a nav aid etc

Question 3

Radar contact definition

Answer 3

A/c has been ident on the radar display + instructions will be provided until the ATC service has been terminated

Question 4

Posn information is given to the a/c on…

Answer 4

Radar ident

Termination of radar service

Question 5

A/c will not be radar vectored

Answer 5

Closer to the edge of the RVA than 1/2 radar separation or 2.5nm whichever is the greater

Question 6

Radar controller is responsible for

Answer 6

Ground clearance of the a/c

Gives mag HDG

Question 7

Radar vectoring - ILS req

Answer 7

Closing HDG is limited to 45*

Modes 1 and 2 is limited to 30*

Closing HDG is to be maintained for not less than 1 nm

Question 8

Radar controlled approach when will a pilot be advised to carry out a missed approach

Answer 8

If radar contact is lost during the last 2nm

Question 9

Approach radar controller will be responsible for

Answer 9

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

Question 10

SRA

Answer 10

Surveillance radar approach

Distances are passed to the a/c from the threshold and advisory heights
N/p approach
Approach controller responsible for the fwd l/d clearance from a/d to the a/c

Question 11

SRA - normal radar termination range (RTR)

Answer 11

2nm or less

RTR is 2 - Range and advisory heights are passed every 1nm

RTR is 1 - range and advisory heights are passed every 1/2 nm

Question 12

Aerodrome control - succeeding a/c will not be cleared for t/o until

Answer 12

The first has either

Crossed the upwind threshold

Commenced a turn away from the r/y

Question 13

A/d control - arriving a/c clearance to l/d

Answer 13

Normally at 2nm but no later than 2nm - if not = m/a

Question 14

What is a l/d after clearance

Answer 14

Not a clearance to l/d - provisional

Passes the responsibility to the pilot of the second a/c

Question 15

Necessary conditions - land after clearance

Answer 15

Daylight
Pilot of second to see the preceding a/c throughout the manoeuvre
R/y is dry and occupancy is limited to 50secs
ATCO can see the entire length of the r/y

Question 16

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

Answer 16

R/y in use

Wind speed and direction

QNH

Question 17

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

Answer 17

In the vicinity of the aerodrome

Question 18

Aprch control service are found in

Answer 18

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

Question 19

Aprch control in an aprch control service is responsible for

Answer 19

Giving clearance for t/o

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

Question 20

Delays - control of a/c

Answer 20

ATC advise operators when the delay exceeds 30mins

Question 21

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

Answer 21

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

Question 22

An IFR flight can be cleared fora visual aprch if

Answer 22

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

Question 23

Speed control will cease when the a/c

Answer 23

Has passed 4nm from l/d

Question 24

Unfamiliar procedures

Answer 24

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

Question 25

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

Answer 25

5mins flying time of the holding area

Question 26

EAT and who is is applicable to

Answer 26

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

Question 27

EAT must be sent

Answer 27

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

Question 28

Info for arriving a/c on the final aprch

Answer 28

Sig changes in mean surface wind speed and direction

Windshear

Vis and RVR

Question 29

Air traffic advisory service

Answer 29

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

Question 30

Emergency descent

Answer 30

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

Question 31

Fuel jettison is not allowed

Answer 31

Below 6000

Over towns

When CB activity is reported/expected

In CAS - need to inform ATCU

Question 32

Strayed/unindent a/c

Answer 32

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