Air Departures

Question 1

When can you issue a conditional clearance?

Answer 1

When there is only one landing or departing aircraft affecting the crossing or entering traffic.

All traffic is visible from the VCR.

Question 2

What are the restrictions with an A-SMGCS conditional line up clearance?

Answer 2

Normal Vis and VIS 2 only:

1. ) RVR >600m and entry points up until A4, NB3, NB8 and A13.
2. ) A-SMGCS configured appropriately
3. ) Departure v Departure only
4. ) Line up clearances only
5. ) No multiple line ups

If the MDS fails (primary only) then this procedure cannot be used.

Question 3

Minimum noise routings apply to all aircraft except?

Answer 3

Propeller driven aircraft whose MTWA does not exceed 5,700kg

Between 0600-2330hrs local, propeller driven aircraft who’s MTWA does not exceed 17,00kg

Question 4

When can you deviate from an MNR?

Answer 4

1. ) Aircraft in an emergency or on safety grounds
2. ) Police, Emergency helicopter flights or other flights CAT E and above
3. ) When a nav aid associated with an MNR is U/S
4. ) To provide separation for any calibration flight
5. ) On easterlies to provide separation from H9 traffic either overflying or landing at Heathrow
6. ) Weather avoiding

Question 5

What do you do if an aircraft cannot make the minimum climb out gradient

Answer 5

Co-ordinate with TC SVFR and the relevant TC outbound sector

Question 6

When has a vehicle or aircraft fully vacated the runway?

Answer 6

An aircraft or vehicle is considered runway vacated when every part of it is at least 77.5m from the runway centre line

Question 7

What anticipation can you use when issuing a take off or landing clearance v another lander?

Answer 7

When the lander has cleared the runway white lines (25m from the centre line) and is in motion and can be expected to be at least 77.5m from the centre line by the time the departure starts to roll or lander reaches the threshold

Question 8

What are the restrictions when departing behind an A340?

Answer 8

If 2 minutes or more is specified, the full time separation must be applied. Separation must be assured before transferring to TC and any levels or headings given must be co-ordinated with TC

Question 9

What is the separation between a DET followed by a MAY, or MAY v MAY on Westerlies?

Answer 9

3 minutes

Question 10

What is the separation between DET v DET on Westerlies?

Answer 10

3 minutes - at 2100 local the VCR Supervisor should contact the GS A to cancel the 3 minute MDI. Then they are to update the log, inform HOEC, update CDM HMI and create an INFO FDE

Question 11

What is the separation between DET v DET on Easterlies?

Answer 11

Between 0700-0800 local - 3 minutes

All other times 2 minutes

Question 12

What is the separation between a MAY followed by a MID or GASGU on Easterlies?

Answer 12

3 minutes

Question 13

What is the separation between a GASGU followed by a MID or CPT standard heading on Easterlies?

Answer 13

3 minutes

Question 14

What would you do if a departure suffers a transponder failure?

Answer 14

Contact the outbound TC sector and if they are not available instruct the aircraft:

‘(Callsign) report that you have a transponder failure to London Control on (frequency)’

Question 15

On Easterlies following a runway alternation from 09R to 09L, what new clearance would you give an aircraft on a CPT departure?

Answer 15

Only inform the pilot of the revised runway for departure, clearance remains the same

Question 16

What Easterly departures are subject SVFR and what notice should you give?

Answer 16

All A340-2/300 & A380 CPT departures are subject SVFR and you should give at least 5 minutes notice

Question 17

What are the restrictions for a vehicle or aircraft entering the 27L Glide path critical area when the ILS is switched on?

Answer 17

No aircraft or vehicle are permitted to enter when an aircraft is:

1.) Carrying out a full ILS approach
&
2.) Seen to be established on the extended centreline
& 
3.) 20nm or less from touchdown

However, a vehicle may be cleared to transit through provided that:

1. ) 3m or less in height
2. ) Any aircraft carrying out an ILS approach is >4nm out
3. ) LVP’s not in force

Question 18

What would you do if the 27L glide path critical area is infringed with an inbound not yet established on the ILS?

Answer 18

Phone INT on PTY line, inform them & how long it’ll be infringed for.
Confirmation of the availability of the glide path ASAP

Question 19

What would you do if the 27L glide path critical area is infringed with an inbound established on the ILS?

Answer 19

Phone INT and agree a course of action.

Question 20

Before weather avoiding begins who do you need to co-ordinate with?

Answer 20

TC SVFR - to determine the presence of any conflicting low level traffic and the status of Northolt’s delegated airspace

Question 21

If WX avoiding begins and TC SVFR inform you that Northolt have their own airspace, what should you do?

Answer 21

Ensure EGWU line is selected on VCCS.
Place a Check North FDE into the runway bay.
Air departures will co-ordinate with Northolt if any northbound requires to go further north of their track

Question 22

What should you do when WX avoiding stops?

Answer 22

Inform TC SVFR, relevant outbound sectors and the VCR supervisor.

Question 23

What is the affect on Easterlies when EGLC have a calibration flight for Runway 09?

Answer 23

Free-Flow suspended for BPK, ULTIB or DET as appropriate.

Question 24

What is the affect on Westerlies when EGLC have a calibration flight for Runway 09?

Answer 24

A gap is needed on the approach or inbounds kept high on the approach

Question 25

What are the Westerly restrictions during the calibration of EGLF’s Runway 24?

Answer 25

All serials affect southbound departures.
27L must not be used for landing.
Farnborough Check FDE.
CPT, GOGSI, MID - RWY HD/6000ft
DET - RS TC SW, RWY HD/6000ft

Once approved Air Deps must inform TC SW that Southbounds will be departing in accordance to the above.

Once complete Air Deps will require a release for the first standard southbound departure with TC SW.

Question 26

What are the Easterly restrictions during the calibration of EGLF’s Runway 24?

Answer 26

Farnborough Check FDE.
MID/GASGU suspended.
DET - Freeflow, LON DME 2, Right heading 115/6000ft
CPT - RS INT S, LON DME 2, Right heading 115/6000ft

Once approved Air Deps must inform TC SE and INT S that Southbounds will be departing in accordance to the above.

Once complete Air Deps will require a release for the first standard southbound departure with TC SE/INT S

Question 27

What would you do as Air Deps if there is a sudden radar failure at TC?

Answer 27

TC may request a stop on departures. If one is already departing it can continue but inform TC of the type, destination and ATC clearance. The departures controller is to co-ordinate the departure track with TC SVFR
