DEO attendance:
Ask WM/ SCOD, if authorised by AM use table 1 sec 5 2.13
Change ILS co ordinate with GSA, EFPS strip and log

Outside DEO attendance
Ask WM/SCOD, if authorised by AM use table 2 sec 5 2.13
ILS status change co ordinate GSA, EFPS strip and log

17
Q

What do you do if runway de classified to non instrument runway?

Ask WM/ SCOD, LLAOs decision
Must co ordinate with GSA and NOTAM
No instrument approaches including SRAs

Strip active - after pressing Enter on clearance box 
GMC
At holding point - transfer to Air
AIR 
cleared take off and airbourne 
Any position 
Delay message
27
Q

Who is responsible for duplicate FDEs and what colours are they?

A

The controller
Black on grey in the duplicate panel if in planned
Blue highlight if active, do not delete until correct fde ascertained and cycles through from planned.

Q

What happens if AFTN fails?

A

No new flight plan or CFMU messages. If NAS data received will get skeleton FDEs
CFMU data must be monitored using AFTN/DSM terminal in VCR enter CTOT on FDEs using IFR edit

31
Q

What happens if NAS link fails?

A

All CIDs will be removed from active FDEs and flow needs to be put in place
FDEs will still be produced
No arrival estimates so verbal coordination with TC
Free flow suspended
When restored reconcile messages on all FDEs
Yellow SID box must be reconciled, re confirm clearance to aircraft and on strip.

32
Q

What are the EFPS contingency procedures?

A

Alarm means power has been lost and system supported by UPS for up to 40 minutes
Print strips on BOCA printer, if it fails use copper chase (IFPS only)
Get NAS data from TS FDS east
Call DEO, GSA, TC luton (suspend freeflow)
Suspend TMA free flow, verbal co ordinate with pre notes for each departure
Reduced flow
Tell AOCC reverting to paper strips as require verbal notification of stand numbered they need info on ARR - flight plan, squawk, ETA, ATA and DEP - flight plan, squawk, SID/ SDR, ATD

33
Q

What two networks provide data link?

A

ARINC and SITA

34
Q

What different colours do DCL turn?

A

Auto DCL are salmon no action required

DCL are blue, once populated turns salmon

35
Q

What flights cannot use DCL? What do you do?

A

VFR
Olney departures
Revert to voice

36
Q

If the transmitters fail on the VCCS what voice system do you use? What limitations does it have?

A

EVCS (red handset)
Shouldn’t be used for more than 30 minutes must be suspended after.
Local crash facility not available

37
Q

Can operations continue without EVCS?
