Degraded Modes Flashcards
MRTS
Multi Radar Tracking Subsystem
RTP
Radar Tracking (Bypass) Processor
MTP
Multi Track Processor
SNMAP
Safety Net and Monitoring Aids Processor
QNH
QNH Data Processor
Which 2 radar processors facilitate the bypass mode?
RTP & MTP
MRTS function
Receives and handles data from all available radar sensors and generates system tracks.
Functions in conjunction with SNMAP to generate some alerts.
When MRTS fails, what mode does the system go into?
Bypass Mode
RTP/MTP function
Recieved and handles data from all available radar sensors generating system tracks onto the service LAN network
MRTS Failure Indications
GIW System Mode - DEGD
GIW Position Mode - DEGD
Main Radar System Mode - NOPS
Main Radar Position Mode - BYPS
Radar Bypass Mode consequences
- Radar alerts are no longer generated
- Radar coupling performed locally
- Radar APRs are not processed
- Initiated Bypass QNH Mode
Are RAD TAGs retained in upgrading MRTS to NORM?
No.
When can controllers upgrade workstations?
When advised by the System Supervisor
SNMAP functions
- Couples system tracks with flight plans
- APRs
- RAM, CLAM
- STCA, MSAW, DAIW, TDAW
In the event of SNMAP failure, what occurs?
- 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
If a subsequent processor failure occurs what HMI indication is there?
The ‘Position System Mode’ button background flashes until the controller selects the button.
QNH failure indications
GIW - BPS/LOC/OFL
Who can update OPS QNH manually in NORM radar mode?
Supervisor
Where does the UFB obtain data?
- 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.
How is the UFB displayed?
By pressing the red button located within the AGA Bypass recess.
When should UFB be used as a primary source of situation awareness?
- 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
How many radars does the UFB process and display data from?
One.
Will the UFB compare position symbols with Mode A codes against the flight plan list?
Yes. If a match is found, the callsign will be allocated to the position symbol.
Does the UFB have a dupe check or aural alarm?
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.
Which ADS-B ground stations does the UFB display data from?
All
What consequences does a longer Eurocat failure have on the UFB display?
- 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
What do you see at your workstation with an FDP failure?
- Handover In and Handover Out strips go to Jurisdiction window
Functions lost with FDP failure?
- 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
Functions within FDP failure
- 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
FP1 vs FP2
FP1 - created before FDP failure
FP2 - created after FDP failure, or any FP1 modified after failure (FP2 indicated by diamond strip designator)
How is SSR code for FP2 obtained?
FDC advises code to use.
What will FP2 routes accept?
Known points or lat/long only
Which alerts remain in FDP failure?
FP1 - MSAW, STCA, DAIW
FP2 (modified FP1) - Unreliable
FP2 (locally created) - none
