When does the transfer of control happen with a inbound?

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


What is the TC Heathrow landing procedure?

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.


What happens if the ILS localiser critical area is infringed?

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


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

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


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

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.


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

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

'(Callsign), you are ... miles ... behind a ... caution wake turbulence'


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

TC FIN must be contacted and any instructions relayed.

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


What are the 3 modes of TBS?

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


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

The approach must be discontinued.


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

<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


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

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'


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

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

3nm ahead and behind for departure separation.


What is the criteria for minimum 2.5nm radar spacing?

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


What are the conditions for spacing below 3nm?

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


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

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


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

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


When will RNAV approaches be used?

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


What temperature is important during RNAV approaches?

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


What is the MAP for 27L?

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.


What is the MAP for 27R?

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.


What is the MAP for 09L?

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.


What is the MAP for 09R?

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


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

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


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

The Westerly alternation will be suspended.

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


What are the missed approach holding patterns?

1 minute racetrack pattern turning left.

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


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

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.


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

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
