Air Arrivals

Question 1

When does the transfer of control happen with a inbound?

Answer 1

Until an aircraft passes 4 DME however transfer of communication can happen earlier

Question 2

What is the TC Heathrow landing procedure?

Answer 2

TC Heathrow will telephone Air Arrivals for a landing clearance. If a landing clearance isn’t available by 2nm it may be appropriate to keep the telephone line open.

Question 3

What happens if the ILS localiser critical area is infringed?

Answer 3

Aircraft established on the ILS, who are unable to continue visually or another type of approach, MUST be re-positioned.

Question 4

What restriction is there when vacating at S5E and holding after vacating?

Answer 4

Code E & F aircraft are still occupying the runway when vacating at S5E and holding on Sierra short of Whisky

Question 5

What are the restrictions when using S4W/S5W for a line up or exit?

Answer 5

S4W/S5W have lead off’s for 27L only and lead on’s for 09R only.

Code E & F aircraft vacating at S4W and holding at SY4 will infringe the runway behind.

Question 6

What is the procedure for when there is a reducing in wake turbulence with the lead aircraft inside 4nm and eTBS is OFF

Answer 6

Reduction of up to 0.5nm is okay and you are to inform the following:

‘(Callsign), you are … miles … behind a … caution wake turbulence’

Question 7

What is the procedure for when there is a reducing in wake turbulence with the lead aircraft outside 4nm and eTBS is OFF

Answer 7

TC FIN must be contacted and any instructions relayed.

If the separation loss is greater than 0.5nm then the approach must be discontinued.

Question 8

What are the 3 modes of TBS?

Answer 8

Time
Distance - usually when there is no traffic for 15 minutes
Off - DBS + 1 minute

Question 9

What happens if there’s No Line Zero information and the following aircraft infringes the wake indicator?

Answer 9

The approach must be discontinued.

Question 10

TBS on - reduction in wake turbulence and the lead aircraft is outside 4nm

Answer 10

<0.5nm - FIN will try to re-establish separation and if the aircraft is on Air’s frequency call FIN to relay instructions
>0.5nm - discontinue the approach

Question 11

TBS on - reduction in wake turbulence and the lead aircraft is inside 4nm

Answer 11

If the loss is 0.5nm or greater then this shall be passed:

‘(Callsign), you are … miles less than the required separation behind a (aircraft type) caution wake turbulence’

Question 12

What happens with inbound type aircraft not within he RECAT EU wake turbulence group? (A225, A400, B2, B52, K35E)

Answer 12

TC Fin will provide 5nm ahead and 10nm behind.

3nm ahead and behind for departure separation.

Question 13

What is the criteria for minimum 2.5nm radar spacing?

Answer 13

1. ) The second aircraft is within 20nm of touchdown
2. ) Heathrow 10cm or Bovingdon 23nm in use
3. ) No wake turbulence
4. ) Individual pairs are closely monitored by TC FIN

Question 14

What are the conditions for spacing below 3nm?

Answer 14

1. ) RSVA is able to be applied when the following aircraft is 6.5nm from touchdown
2. ) Braking action is good
3. ) ATM serviceable
4. ) A8/A9E, N5W/S5W, A9W available to exit

If one exit out of two is unavailable, spacing below 3nm can still be approved.

You cannot reduce the 3nm for 09R

Question 15

TC may established successive aircraft on adjacent parallel runways separated diagonally by 2nm subject to the following conditions:

Answer 15

1. ) Both aircraft established on the ILS for different runways
2. ) Priority lines are serviceable

Question 16

When can separation be reduced below 2nm for aircraft established on adjacent parallel runways?

Answer 16

1. ) Aircraft are established on ILS LOC
2. ) Visual separation can be maintained by the following pilots
3. ) Air controller informed
4. ) Priority lines serviceable
5. ) Controllers monitor the MET conditions

This is not to be used for aircraft flying an RNAV approach

Question 17

When will RNAV approaches be used?

Answer 17

1. ) During TEAM
2. ) Quieter periods or when minimum spacing isn’t being utilised
3. ) When requested by pilots or appropriate for ATC

Pilots are unlikely to fly an RNAV approach when Vis is <4000m and/or cloud ceiling <700ft

Question 18

What temperature is important during RNAV approaches?

Answer 18

If the temperate falls below -10 degrees the pilots must be informed of this and any changes below that

Question 19

What is the MAP for 27L?

Answer 19

Climb to 2000ft - straight ahead until passing 1080(1000)ft or Zero DME ILL inbound, whichever is later, then left onto track 147°M. When established and passing 6 DME LON climb to 3000ft without delay. Continue as directed by ATC.

Question 20

What is the MAP for 27R?

Answer 20

Climb to 3000ft - straight ahead until passing 1580(1500)ft or Zero DME IRR inbound, whichever is later, then right onto track 316°M. Continue as directed by ATC.

Question 21

What is the MAP for 09L?

Answer 21

Climb to 3000ft - straight ahead until passing 1580(1500)ft or Zero DME IAA inbound, whichever is later, then left onto track 037°M. Continue as directed by ATC.

Question 22

What is the MAP for 09R?

Answer 22

Climb straight ahead to 3000ft. Continue as directed by ATC.

Question 23

What will Northolt do when they hear the MAP alarm and have an outbound airborne or almost airborne?

Answer 23

Northolt will restrict their traffic to 2000ft and contact Northolt approach on the priority line

Question 24

With regards to missed approaches, what happens if there is a total DME failure for landing runway?

Answer 24

The Westerly alternation will be suspended.

This does not apply to Easterlies and ATC will inform the aircraft when to turn.

Question 25

What are the missed approach holding patterns?

Answer 25

1 minute racetrack pattern turning left.

CHT - NDB 293, minimum holding 3000ft
EPM - NDB 274, minimum holding 3000ft

Question 26

What happens in the event of a missed approach and radio failure?

Answer 26

27R/09L - Follow AIP procedure for 10nm and make a left or right turn at CHT at 3000ft
27L - Follow AIP procedure for 6nm, climb to 3000ft then proceed to EPM
09R - Follow AIP procedure for 10nm, turn right to EPM.

Question 27

What would you do as the departure controller if there is a sudden loss of the arrival runway?

Answer 27

Make the departure runway available as soon as possible and allow FIN to carry out standard spacing for 10 minutes on Westerlies and 15 minutes on Easterlies
