LPO Phase 3 - De-Icing and Snow Clearance

Question 1

When will SNOCLO procedures be used?

Answer 1

Only when the landing area is completely unusable and the AFDM informs the VCR Sup that the excessive accumulation of snow makes the landing area unusable.

Question 2

What is JEDI?

Answer 2

A joint effort between BA, HAL, and ATC to allow for BA aircraft to be de-iced on a remote part of the airfield, the benefit being that it frees up stands or inbound aircraft and allows for a continuous de-icing, which is more efficient

Question 3

What are the 3 states of JEDI?

Answer 3

Open, Standby and Closed

Question 4

What do the 3 states of JEDI mean?

Answer 4

Open: JEDI area is in force and there are restrictions to the ground space that ATC have to adhere to
Standby: JEDI Area is set up for de-icing with rigs and boards in place, but there is no ATC restrictions associated with the JEDI locations
Closed: JEDI is no longer in force and rigs and personnel stand down.

Question 5

Can an aircraft be given pushback approval for JEDI, if JEDI is in standby?

Answer 5

Yes

Question 6

If told by the VCR Sup that JEDI is open, as the LPO what do you do?

Answer 6

Ensure that the appropriate maps/OSIs are selected on the ASMGCS and the MCP

Question 7

Where is the JEDI pad controller located and how do you contact them?

Answer 7

They are located between stand 581 and taxiway D and can be contacted via the VCCS panel by selecting JEDI

Question 8

Describe where JEDI south is

Answer 8

B south between C and E. The aircraft are positioned abeam stand 581 whilst they are de-iced, and must approach from the west.

Question 9

Describe where JEDI D is

Answer 9

on taxiway D between stands 568 and 566. The aircraft are positioned on D facing north abeam stand 568 when being de-iced and when they are finished, they taxi to an intermediate stop line between abeam stand 566 and 565.

Question 10

What do you do if an aircraft wishes to park/tow/push on stand 582 or 583 when JEDI south is open?

Answer 10

Coordinate with the pad controller and decide when the traffic can move and how it can approach, typically from the east.

Question 11

Whilst JEDI south is open, you wish to route an aircraft through D1. What must you do before this can happen?

Answer 11

Coordinate with the pad controller

Question 12

What is the restriction with stand 568 when JEDI south is open

Answer 12

As a pushback from 568 infringes taxiway B when facing north, any pushbacks or engine starts must be coordinated with the pad controller prior to it being approved by ATC.

Question 13

When coordinating with the pad controller about aircraft movements, what key descriptive piece of information is necessary over the phone

Answer 13

To mention the aircraft type, so it is more easily identified as well as some aircraft types requiring the repositioning of the de-icing rigs.

Question 14

Whilst Jedi Delta is open, what must you do if you wish to route an aircraft into or out of 565-568 or 575-576

Answer 14

Coordinate with the pad controller

Question 15

Can JEDI be used in LVPs?

Answer 15

Yes

Question 16

If the AGL is on and a request to use the area inside JEDI south has been coordinated with the pad controller, what must you do on the panel?

Answer 16

Switch off JEDI south via the winter ops menu, route the aircraft and then switch JEDI south on again.

Question 17

During snow clearance when will SNOCO1 be based

Answer 17

In the VCR

Question 18

How is a snow area activated?

Answer 18

Via the winter ops menu on the panel

Question 19

What happens to the reds and greens when a snow area is activated

Answer 19

The reds and greens are suppressed in the area that has been selected and red bars surrounding it are brought up to protect the taxiway teams inside

Question 20

What happens to the reds and greens once the area is completed with?

Answer 20

The reds will be dropped and there will be no green lights within the area illuminated

Question 21

What happens if you selected a snow area adjacent to a runway?

Answer 21

A box wil come up asking the LPO to select the runway mode in use. The options being 09X, 27X, BOTH, NONE or no if you wish to cancel

Question 22

What does selecting the runway mode when selecting a snow area do?

Answer 22

It will illuminate or suppress the relevant RGBs for that runway so that the snow clearing teams can move back and forth as they need to on the runway exits.

Question 23

The AGL is on, the runway is OFF, and you select NONE when activating the snow area adjacent to the runway, what happens?

Answer 23

All RGBs are suppressed

Question 24

Will an active snow area show up on the RCP as well as the MCP?

Answer 24

Yes

Question 25

The runway is set to OFF and the snow areas adjacent to the runway are selected as NONE. Then the runway is set to ARR, DEP, or MIXED. What happens to the RGBs?

Answer 25

They will change to reflect the selected runway mode.

Question 26

When a runway team is mustered at M1 and wishes to enter the runway to start snow clearance, what is the step by step process with regards to selecting things on the MCP/RCP?

Answer 26

The ARR ATCO will put the runway into OFF mode. Then they will clear the team onto the runway and suppress the A1 bar. Then the LPO will activate the runway snow area. Then snow clearance can begin.
