Section 8 - Disruption Of Air Traffic Services Flashcards
When is the tower evacuated?
Fire alarm or car abandoned in the underpass that is assessed as suspicious
What must you do, and not do in an evacuation?
Follow the VCR evac checklist in the emergency folder
Do not use the lift
NOTAM - in an emergency pilots call LLAO in 01582395525
What events require contingency measures?
What action are considered? (7)
FLOP, SSR, CCDS or NAS link failure Print Boca or Copperchase FPS Check flight data to ensure conformity Request FDS supply inbound estimates and SSR codes by phone OSS to pass these to AOCC Restrict departure rate (stop all dep if a FLOP) Cancel training flights Coordinate with TC luton
What system failures affect movement rate (6)
Are the flow rates the same in LVPs?
SMR, ATM, CCDS, NAS Link/EFPS, Stopbars, both strip printers
No, they decrease in LVPs, in LVP B an AOD vehicle may be required otherwise no movements can take place
(Table section 8 2.2)
Who determines the flow rate if movements are restricted? Who do they tell?
WM/ SCOD determine gaps to fit flow and tell GSA, traffic manager and AOCC
Also to advise traffic manager of any change in LVP status and agree new rate (log it!)
Can you give a conditional clearance to cross any illuminated stop bar?
NO!
What actions do you take if the runway stop bar is failed ON?
LLAO requested to provide AOD vehicle to escort aircraft over the runway stop bar, give own specific clearance.
Must be visible to the controller, can be satisfied by use of SMR. Applies to aircraft, vehicles and tows
What actions do you take if runway stop bar is failed OFF?
AOD vehicle to act as temporary barrier, they will monitor the frequency and vacate when a movement takes place.
If not possible the holding point to be removed from service using a portable barrier.
If the vehicle requires access to the runway, to vacate follow standard procedures.
Caution as increased risk or runway incursion, can be used in LVPs and at night.
What do you do if an intermediate stop bar is failed ON?
Follow Mats 1 sec 2 chap 1, 11A. Should be visible to controller, can use SMR. Pilot should be in no doubt as to their instruction
What do you do if an intermediate stop bar is failed OFF?
No affect CAT 1 or LVP A
In LVP B a block is between operable stop bars only.
What phraseology would you use to cross a stop bar stuck ON? What is the exception?
….. cross the illuminated stop bar/s at…
RFFS in emergency do not need to specify individual lit stop bar to cross.
If LTCC evacuate what procedures are to be followed?
Airbourne traffic in contact with air offered immediate return to land. If visual circuit and landing not possible may not be available as no radar service.
TC will stop all departures, transfer established arrivals on final to tower, issue air with holding instructions for airbourne aircraft still with tower.
If London Area in Manual and FLOP what can your expect?
GSA will inform ATC, may stop all departures and issue CTOTs as required
BOCA or copperchase strips to be generated and GSA will release aircraft on a tactical basis
TC pass verbal estimates and squawks for all arrivals, pass to AOCC
Departures squawks from the appropriate FDS position.
GSA will instruct when normal ops can be resumed
Where do you find details of volcanic ash procedures?
Airport operations policy folder
What is SLAM also known as and where do you find details?
Operation velvety
In the emergency actions folder at each position
Where do you find actions to be taken in the event of aviation security?
What can they be split into?
Green section of the emergency actions folder
Airbourne security threat - hijack, bomb threat ect
Ground to Air security threat
What are the levels or disruptive passengers?
Level 1 - disruptive behaviour Level 2 - physically abusive Level 3 - life threatening behaviour Level 4 attempted or actual breach of cabin Tell GSA immediately
What actions do you take in the event of a laser attack?
Follow guidance in airport operations policy folder
What actions do you take following the report of unauthorised SUA activity? (4)
Note the time
Note the altitude and position as notified
Note the description - shape/ colour
Note any avoiding action taken by pilot
Report to pilots - down to them to decide action but give traffic avoidance if appropriate
How long after report of SUA do you tell pilots? What phraseology is used?
30 minutes
All stations/callsign (SUA descrition) reported approximately/ overhead/ at… and appears to be at …. height
Use 3nm 3000ft as in the vicinity to give TI
What report do you file on all reported events?
CA 4114 (MOR) Follow table sec 8 5.7 for who to report too
If possible what information on SUA is passed to Luton airport?
Number of SUAs
Can you see the operator?
Is there a vehicle nearby? Description?
Name and details of who made the report.
If infectious diseases are suspected on an aircraft what do you do?
Follow the actions in the LLAO emergency orders folder
When does the winter operations plan run from?
1st November to 30th April
What met warning do we give AOCC
Snow, frost, freezing precipitation
Who coordinates the winter operations plan? What are the key call signs?
AM - ops 1
Ranger - ODM supports AM
OPS4 RFFS manager
Snowman - in snow event AOCC controller who communicates with all interested parties
Who decides to close the runway? How much notice is given?
The AM they decide if remains open or closed
Try and give 30 mins notice
What categories of runway closure are there?
What do you do when told runway closed?
Temporary suspension of runway movements -
Contamination levels do not permit safe use anti icing ops requires
SNOCLO2 - Expected to close for 2 hours. Usually when ceased snowing and no further snow expected
SNOCLO4 - persistent snow fall, moderate to heavy, update every 2 hours. Can be extended.
WM/SCOD tell GSA and TC luton immediately
Put on ATIS
Tell AOCC of all holding inbound or diverts out.
Turn off all stop bars and lead off to allow free range.
LTCC cannot vector aircraft to closed runway so arrivals may hold until reopen.
Can you sweep runway between aircraft movements? What actions do you take?
Yes, AM will prenote if it is planned and park close to area to be treated.
Vehicles can vacate in less than 5 minutes
Request 15nm range check from TC for each landing aircraft
What is the friction measure called? How long does it take?
Griptester
It takes 15 minutes and can vacate in less than 5 but if test aborted it will need to re run the whole thing as any reading unusable
Requesting 15 miles range check from TC for each inbound
Do you pass griptester data to air crew?
No!
If snow if on the railway surface can you move aircraft and vehicles?
LLAO snow clearance vehicles and emergency response RFFS only
Who decides to close a taxi way?
AM
ODM will escort bowsers ect if no alternative route - transparent to ATC they will contact us
In severe weather which runway holding point is given priority?
Charlie - for inbounds and outbounds
How do you report runway surface conditions in snow?
SNOWTAM and 8 figure state to METAR suffice via AFTN and OPMET
Use freezing conditions runway report form and give comprehensive essential aerodrome information concerning runway surface conditions and deposits
Do not give pilot report if suggests better than official report, if worse tell AM
Can WIP continue if snow forecast overnight?
No, open trenches must be filled and all equipment removed from manoeuvring area.
What must happen before the runway reopens?
Inspection by ODM, with or without Griptester
Is remembrance sunday observed at Luton?
Its voluntary and no restrictions imposed but…
1058-1103 no ground running of engines allowed, arrivals should land in sufficient time to be parked by 1058 but may taxi to stand if not possible
If crew request start in this period - ‘The airport is observing the remembrance sunday period of silence. If possible you are requested to delay engine start until 1103’
Where is the airfield closures checklist for pre planned closure?
QRH
What is Plan 39?
The plan for mass diversion when an event occurs at airports within LTMA
What does plan 39 mean for luton?
LLAO pre authorised up to 4 code C aircraft to be diverted without consultation subject to
Pan/mayday aircraft excluded, must be coordinated
Airlines not listed are excluded (RYR,RUK,WZZ,WUK,EZY,EJU)
Diversions subject to normal co ordination
Over 4 aircraft must be coordinate individually
How do we know plan 39 is in use?
GSA will call, we tell LLAO and request tow and vehicle movement kept to a minimum
Tell WM/SCOD and available staff to provide assistance
How do we know plan 39 had finished?
GSA will call, tell us plan 39 has ceased. Tell LLAO
Will be when flow rate has stabilised or diversions are manageable enough to coordinate individually
Can plan 39 be revoked?
LLAO may be unable to fulfill obligation if WIP, they will tell ATC, ATC to inform GSA plan 39 invoked.
