WACOM MONITOR FAILURE IN ADC.

Move across to GMC position with headset.

Select Role as ADC.

Select frequency.

Continue operation.

Inform DEO (possible ENG call out).

WACOM MONITOR FAILURE IN RADAR - INT OPEN.

Move across to FIN position with headset.

Select Role as INT.

Select frequency.

Continue operation.

Inform DEO (possible ENG call out)

WACOM MONITOR FAILURE IN RADAR - INT AND FIN OPEN.

FIN Fails.

FIN ATCO reverts to paper pro forma.

No further traffic accepted.

FIN closed when traffic has left the frequency.

FIN ATCO assists INT ATCO as required.

Inform DEO (possible ENG call out).

INT Fails.

All departures are stopped and inbounds are to be sent to the hold.

FIN reverts to paper pro forma, swaps positions with INT, selects 120.9 and continues operation.

INT moves to FIN position with headset.

Select Role as INT.

Select frequency.

Continue operation.

FIN ATCO assists INT ATCO as required.

Inform DEO (possible ENG call out).

NAS FAILURE.

When NAS fails EFPS will continue to operate using AFTN data only.

IMPACT:

Loss of - Estimates
SSR codes
PC electronic co-ordination (departure warnings)
Flight plan data

ACTIONS:

* Pass departure warnings to PC and request SSR codes
* Pass airborne times to PC
* For RAD, PC will pass estimates and squawks via telephone

EXPECT:

* TSM (Technical Services Manager) will telephone stating awareness of fault and what resolution action is being taken. NB: telephone them if they don't call within 15 minutes.

NB - PC derive SSR codes from a system called CCAMs (Centralised Code Assignment and Management System) in Brussels and have methodology in place if this system fails.

AFTN FAILURE.

IMPACT:

Current data retained

Lose any VFR flight plans

No slot revisions unless local AFTN still functional.


ACTIONS:

Manual entry of flight plans.


EXPECT:

UK FMP will phone us with slots and updates

TSM will telephone stating awareness of fault and resolution action is being taken.
Phone them if they don't call within 15 minutes.

NAS & AFTN FAILURE.

IMPACT:

Lose future flight information (we retain approximately 40 minutes of traffic but no further updates). Info is going stale from time of failure.

Expect possibility of outbounds returning.


ACTIONS:

Stop departures at EGAA and EGAC.

Transfer outbounds to PC.

Apply zero flow rate.


EXPECT:

TSM will telephone stating awareness of fault and resolution action is being taken.
Phone them if the don't call within 15 minutes.

This will most likely be effecting all airports within the U.K.

SINGLE SERVER FAILURE.

IMPACT:

ASA or ASB fails they will respectively go RED.

No operational impact.


ACTIONS:

None.


EXPECT:

TSM will telephone stating awareness of fault and resolution action is being taken.
Phone them if they don't call within 15 minutes.

DOUBLE SERVER FAILURE.

IMPACT:

ASA and ASB and the Role Indicator (bottom left) will both go RED.

The EFPS screen will freeze continuing to display the picture at the time of the failure.

The screen will be unresponsive.

The failure will be across ALL HUB & SPOKE EFPS Airfields.

EGAC will be carrying out similar recovery action.


ACTIONS:

RAD will stop all departures from EGAA and EGAC.

RAD will inform PC SUP.

Establish zero flow rate.

Controllers will use the paper pro-forma to manage live traffic (Pro-forma kept as a legal document as currently with strips).

Commence Copperchase strip production ( Radar first as traffic more dynamic with addition of City traffic).

Engage use of strip boards and populate with strips - hand write if required.

Co-ordination between ADC and RAD will be effected to recommence the operation.

Establish appropriate flow control.

Inform GM.

Resume EGAA operations.

Liaise with EGAC and approve the recommencement of their operation when ready.


EXPECT:

TSM will telephone stating awareness of fault and resolution action is being taken.
Phone them if they don't call within 15 minutes.

EGAC will request SSR codes for outbounds.

Radar releases for both inbounds and outbounds to revert to telephone.

To pass inbound estimates and SSR codes to EGAC.

DOUBLE BT LINE FAILURE.

ACTIONS:

RAD will stop all departures from EGAA and EGAC.

RAD will inform PC SUP.

Establish zero flow rate.

Controllers will use paper pro-forma to manage live traffic (Pro-forma kept as a legal document as currently with strips).

Commence Copperchase strip production ( Radar first - as traffic more dynamic with addition of City traffic).

Engage use of strip boards and populate with strips - hand write if required.

Co-ordination between ADC and RAD will be effected to recommence the operation.

Establish appropriate flow control.

Inform GM.


EXPECT:

TSM will telephone stating awareness of fault and resolution action is being taken.
Phone them if they don't call within 15 minutes.

TIME FAILURE.

There will be no indication if the TIME fails.

TSM will telephone stating awareness of fault and resolution action is being taken.

The system will continue to work on its internal clock.

When the clock re-establishes connection the TIME will re-sync.

If the TIME feed "jumps" by more than 5 minutes the system will ignore the input and, again, run the internal clock.

PLANNED OUTAGE.

Establish appropriate flow control if required.

At a suitable time commence Copperchase strip production.

Engage use of strip boards and populate with strips- hand write if required.

Swap to paper system when appropriate.

After outage populate EFPS with current data in GMC position under ADC Role.

When ready remove paper based solution and select ADC Role in ADC position.

TOTAL EGAC EFPS FAILURE (EGAA EFPS SERVICEABLE)

EXPECT:

EGAC will inform us via telephone.

EGAC to go zero flow rate until their paper operation is established.

EGAC to request SSR codes for outbounds.


ACTIONS:

Route EGAC inbounds to MAGEE.

Inbounds already transferred may be transferred back.

When EGAC paper operation is established,

Radar releases for both inbounds and outbounds to revert to telephone.

Pass inbound estimates and SSR codes to EGAC.

EGAA EFPS FAILURE (EGAC EFPS SERVICEABLE)

Radar releases for both inbounds and outbounds to revert to telephone.
