Q

In the event of SNMAP failure, what occurs?

A
  • Radar coupling is performed locally
  • APRs are not processed
  • Radar alerts are no longer generated
  • No coupling corridor
  • No DUPE processing, no DUPE alert/warning

Q

If a subsequent processor failure occurs what HMI indication is there?

A

The ‘Position System Mode’ button background flashes until the controller selects the button.

17
Q

QNH failure indications

A

GIW - BPS/LOC/OFL

18
Q

Who can update OPS QNH manually in NORM radar mode?

A

Supervisor

19
Q

Where does the UFB obtain data?

A
  • Via the UFB LAN
  • Recieves a snap shot of the most recently updated Flight Plan Data from the associated EC workstation and displays this in a Flight Plan List.
20
Q

How is the UFB displayed?

A

By pressing the red button located within the AGA Bypass recess.

21
Q

When should UFB be used as a primary source of situation awareness?

A
  • Eurocat partition failure
  • Workstation failure
  • Required by the SS or TCU supervisor
  • During degraded mode of uograde, if UFB provides information not available on Eurocat display
22
Q

How many radars does the UFB process and display data from?

A

One.

23
Q

Will the UFB compare position symbols with Mode A codes against the flight plan list?

A

Yes. If a match is found, the callsign will be allocated to the position symbol.

24
Q

Does the UFB have a dupe check or aural alarm?

A

No. If two or more aircraft have the same mode A code both will correlate to the same flight plan. If two flightlans have the same mode A code associated then the radar track will be correlated with the first flight plan on the display list at the time of the track update.

25
Q

Which ADS-B ground stations does the UFB display data from?

A

All

26
Q

What consequences does a longer Eurocat failure have on the UFB display?

A
  • The number of correlated position symbols will decrease due to lack of input/addition to the flight plan list.
  • Strips for aircraft that have left the sector will remain in the flight plan list.
  • CFLs in strips will not change
27
Q

What do you see at your workstation with an FDP failure?

A
  • Handover In and Handover Out strips go to Jurisdiction window
28
Q

Functions lost with FDP failure?

A
  • Sectorisation
  • Flight plan acquisition and evolution
  • Trajectory calculation
  • Messaging
  • ETO/MPR/SAR/CLAM/RAM alerts
  • Traffic management window
  • System Coupling/Dupe Processing/APRs
  • Hand off function
  • Grib Wind Data not available
  • No automatic strip posting
  • RWY
  • Position Report Windows
  • PCLs
  • No label SARtimer
  • No new CPDLC/ADS-C logons
  • Maestro times not updated
29
Q

Functions within FDP failure

A
  • New plans can be created at the workstation but no other workstation can access that flightplan
  • Departures now managed using point estimates rather than DEP time
30
Q

FP1 vs FP2

A

FP1 - created before FDP failure

FP2 - created after FDP failure, or any FP1 modified after failure (FP2 indicated by diamond strip designator)

31
Q

How is SSR code for FP2 obtained?

A

FDC advises code to use.

32
Q

What will FP2 routes accept?

A

Known points or lat/long only

33
Q

Which alerts remain in FDP failure?

A

FP1 - MSAW, STCA, DAIW
FP2 (modified FP1) - Unreliable
FP2 (locally created) - none
