Of the Code F routes available, which route requires a leader escort?

Answer 1

R/L Junction

Question 2

When using an escorted route for a Code F aircraft, what should GMC avoid the aircraft having to do?

Answer 2

GMC should avoid the aircraft having to stop to avoid excessive jet blast

Question 3

Can Code F aircraft be routed under the Pier 6 Connector Bridge?

Answer 3

No.

Question 4

When a Code F is on Alpha-November between P and A3, what is the maximum size aircraft allowed on Alpha-Sierra?

Answer 4

Code D.

Question 5

If an aircraft larger than Code D is on AS, can a Code F be on AN?

Answer 5

No. Code F aircraft must be held short of P while an aircraft larger than code D is on AS

Question 6

Are Code F aircraft allowed on Alpha-Sierra?

Answer 6

Yes. But they are to be considered a runway movement as they will infringe the runway. A 20nm gap is recommended.

Question 7

While a Code F is holding at M1, which taxiway does the tail overhang and block?

Answer 7

Alpha-November at the junction with Mike.

Question 8

While a Code F is holding on Quebec-Bravo short of Quebec-Alpha, which taxiway does the tail overhang and block?

Answer 8

Lima, at the junction with Quebec.

Question 9

While Code F are routing between 558 and 26L via QB -> Q -> 08L -> AN, where must aircraft not be instructed to hold short?

Answer 9

• Facing east on Kilo, short of Quebec
• Facing east on Juliet, short of Quebec
• Facing east on 08L, short of Quebec
• Facing south on Charlie, short of 08L

Question 10

While Code F are routing between 558 and 08R via QB -> Q -> J, where must aircraft not be instructed to hold short?

Answer 10

• Facing east on Kilo, short of Quebec
• Facing north on Quebec, short of Juliet
• Facing north on Romeo, short of Juliet

Question 11

What are the restrictions associated with taxiway Y whilst a Code F aircraft is departing from 26L?

Answer 11

Y between W1 and Y3 (block 14) is not available to any aircraft or vehicle while a code F aircraft is departing runway 26L via A or M

Question 12

When a Code F is routing from Juliet or 08L onto Alpha/November or Bravo, where must other aircraft be held short?

Answer 12

• Short of Juliet southbound
• Short of November westbound

Question 13

Which stands are available for Code F aircraft?

Answer 13

558, 172M, 234M and 235M.

With prior co-ordination, Pier 4 may be used, using Papa and Lima as access.

Question 14

Which runway line-up points may Code F aircraft use?

Answer 14

Any

Question 15

Which runways are available for Code F aircraft?

Answer 15

26L/08R is available for Code F.

However 26R/08L is available for A380 takeoffs and subject to crew discretion, landings.

Question 16

Which Runway exits may Code F aircraft use?

Answer 16

Any except Delta and Echo Romeo

Question 17

What is the specifed limitation on an aircraft using the ILS behind a Code F arrival?

Answer 17

A landing Code F aircraft must have vacated the critical area by the time the next ILS inbound is 8nm from touchdown

Question 18

Behind a Code F arrival, how much non-ILS traffic will INT/FIN provide if weather conditions allow?

Answer 18

15nm of non-ILS traffic behind an inbound code F aircraft, with an initial 8nm gap

Question 19

If weather conditions do not permit non-precision approaches, and INT/FIN therefore must continue with ILS approaches, what is the guidance for ILS aircraft following a Code F arrival?

Answer 19

15nm gap is suggested to allow the code F to have landed and vacated the critical area by the time the ILS traffic is 8nm from touchdown.

Question 20

What is the specifed limitation on an aircraft using the ILS behind a Code F departure?

Answer 20

A departing Code F aircraft must have passed overhead the ILS localiser by the time the next ILS inbound has reached 8nm from touchdown

Question 21

Behind a Code F departure, how much non-ILS traffic will INT/FIN provide, if weather conditions allow?

Answer 21

20nm of non-ILS traffic behind the co-ordinated Code F gap, with an initial 8nm gap then continuing with the previous spacing

Question 22

If weather conditions do not permit non-precision approaches, and INT/FIN therefore must continue with ILS approaches, what is the guidance for ILS aircraft following a Code F departure?

Answer 22

20nm gap is suggested behind the co-ordinated Code F gap to ensure the Code F is rolling by the time the ILS inbound has reached 12nm.

Question 23

What is the name of the larger ILS protected area that Code F aircraft must not infringe during LVPs?

Answer 23

DLSA. Dynamic Localiser Sensitive Area.

Question 24

What must happen to the ASMGCS when a Code F departure or arrival is expected during LVPs?

Answer 24

During LVPs the appropriate DLSA map must be displayed when

• An inbound code F aircraft is established on the ILS until it has landed and is north of taxiway Juliet, or
• A departing code F aircraft has pushed back until it is airborne and has passed overhead the ILS localiser

Question 25

What are the restrictions surrounding a Code F aircraft in the DLSA and other runway movements?

Answer 25

• No landings or departures are permitted until the code F aircraft has vacated the DLSA.
• A landing code F aircraft must have vacated the DLSA by the time the next ILS inbound is 2nm from touchdown
• A landing code F aircraft must have vacated the ILS critical area by the time the next ILS inbound has reached 8nm from touchdown

Question 26

What is the suggested gap behind a Code F arrival during LVPs?

Answer 26

18nm

Question 27

During its inbound taxi route from either runway, when will a Code F infringe the DLSA?

Answer 27

When a Code F is on 08L/26R, and is turning northbound across/into Juliet, the tail will infringe the DLSA

Question 28

Does a Code F infringe the DLSA while taxiing east/west along 08L/26R?

Answer 28

No

Question 29

What is the suggested gap behind a Code F departure during LVPs?

Answer 29

25nm

Question 30

What is the standard route for a Code F aircraft to stand 558?

Answer 30

Juliet or 08L/26R -> Q -> QB and vice versa.
