AIR - Section 4 Flashcards
What is the AIR frequency and what spare is available?
124.230
Spare frequency available on 134.230
Who should be advised when AIR starts/stops using a non-standard frequency?
Redhill ATC
Aircraft via a message added to the ATIS
What priority lines are available to AIR?
TC KK INT - labelled “KK INT PTY”
TC KK FIN - labelled “KK FIN PTY”
TC South - labelled “TC STH PTY”
Which calls should be on a priority line?
Calls of an urgent operational nature that require an immediate response. The recipient should terminate any other telephone conversation.
When should TC KK FIN priority call AIR?
- Final approach separation is being eroded within 10nm from touchdown
- Aircraft declaring an emergency within 10nm from touchdown
- Aircraft which requires a landing immediately after take-off
- Emergency evacuation of TC when normal notification procedures cannot be followed
When should AIR priority call TC KK FIN?
- Go-around
- Emergency traffic
- Emergency separation between departures
- Landing aircraft inside 2nm not contacted AIR
- Passing of a landing clearance inside 4nm when SRAs are in progress
- Emergency evacuation of VCR when normal notification procedures cannot be followed
When should AIR priority call TC South?
Any situation AIR believes requires the immediate attention of TC South
What is the maximum range that the ATCOs are permitted to set the ATM?
30nm
ATCOs may temporarily extend the range, but it must be reset to range of no more than 30nm
What labels MUST be displayed on the ATM?
Callsign
Level (including Mode S)
Ground Speed
What may the ATM be used for at EGKK?
LLSC VODMAP TBM
Basic - LLSC - Landing, Longitudinal, SID, Circuit
1) Determine the landing order, spacing and distance from touchdown of arriving aircraft
2) Assist in applying longitudinal separation for departing aircraft
3) Enable the controller to confirm that the initial track of a departing aircraft conforms with the clearance issued
4) Provide information to aircraft on the position of other aircraft in the circuit or carrying out an instrument approach
Advanced - VODMAP - Validate/Verify, Overflying, Departure, Missed, Arriving, Pass
1) Validate SSR and Mode S of departing aircraft and verify Mode C read-outs
2) Monitor overflying aircraft identified by Approach to ensure that they do not conflict with arriving or departing aircraft
3) Establish separation between departing aircraft
4) Establish separation in the event of a missed approach
5) Assist in taking corrective action when the separation between arriving aircraft becomes less than the minima
6) Pass traffic information
TBM - Training, Bandboxed, MATS 2
* The ATCO must have undertaken specified training
* The ATCO is only providing an Air Control Service and a separate GMC is being provided by another ATCO on a separate frequency
* The procedures are detailed in MATS 2
What should the ATCO say when the Selected Level is seen to be at variance with an ATC clearance?
“(callsign), check selected level. Cleared level is (correct cleared level)”
What is AFDAS?
Approach Funnel Deviation Alert System
What happens on the ATM screen when there is a localiser alert on the AFDAS?
- Aircraft label causing the alert is highlighted in orange on the ATM and in the AFDAS localiser window
- The boundary of the approach funnel area being crossed changes to red
- The audible alarm is sounded
What happens on the ATM screen when there is a glidepath alert on the AFDAS?
- The glidepath window is displayed
- The label of the aircraft causing the alert is highlighted in an orange box on both the main ATM window and in the AFDAS window
- The lower glidepath limit is coloured red
- The audible alarm is sounded
What are the ATCO actions in the event of a localiser alert activated at 1nm or less from touchdown?
Instruct the aircraft to Go-Around
What are the ATCO actions in the event of a localiser or glidepath alert activated more than 1nm from touchdown?
- Advise the aircraft of their apparent displacement
- Seek confirmation that the aircraft is aligned with or visual with the correct runway in use
“(callsign) you are left/right of the centreline. Confirm established on the localiser or visual with (runway in use)”
“(callsign) you are below/above the glidepath. Confirm returning to the glidepath or visual with (runway in use)”
What are the ATCO actions in the event that an aircraft is outside the localiser tracking zone at 1nm or less from touchdown, OR the ATCO believes that the aircraft is dangerously positioned on the approach?
The aircraft must be instructed to Go-Around
Should AFDAS alerts be recorded in the Watch Log? And who else should be contacted after an AFDAS alert?
Yes. Except for Go Arounds or overflights. Pilots should also be contacted for their comments/observations.
What is RIMCAS?
Runway Incursion Monitoring and Collision Avoidance System
What is RIMCAS configured to alert against?
- MDS cooperative (transponding) targets
- Primary targets that enter the runway via a primary detection area
When must ‘Poor Visibility’ be selected on RIMCAS?
- Main Runway Ops - During LVPs
- Northern Runway operations - When visibility is less than 1500m
Which Arrival RIMCAS alerts are advisory and which are mandatory go arounds?
Good Visibility
Stage 1 - Advisory
Stage 2 - Advisory, but ATCOs discretion
Poor Visbility
Stage 1 - Advisory
Stage 2 - Go Around, except when caused by heavy precipitation.
What actions come from Departure RIMCAS alerts?
Stage 1 - Advisory, No action.
Stage 2 - Advisory, action up to ATCOs discretion
What is the width of both 08R/26L and 08L/26R?
45 Metres
What is the length of 26L/08R?
3317 Metres
What is the length of 26R/08L?
2561 Metres
At what distance is an aircraft or vehicle considered to have vacated 26L/08R?
When every part of the aircraft or vehicle is at least 77.5m from the runway centreline.
When is an aircraft or vehicle defined as fully vacated 26R/08L?
When every part of the aircraft or vehicle is at least 60m from the runway centreline.
When can a take-off or landing clearance be issued in anticipation?
When the preceding aircraft
- Has passed the runway edge markings
- Is continuing in the required direction
- Has NOT been instructed to stop before the applicable runway holding position
Describe the CGA?
Cleared and Graded Area
The area around the runway within which there must be no obstructions, and only frangible items, when aircraft are cleared to land or take-off, in case an aircraft runs off the runway.
What are the two distances used for the CGA?
75 Metres from the centreline
and
105 Metres from the centreline
If a vehicle has been cleared to operate inside the CGA, can the runway still be used?
No. When a vehicle has been given clearance to operate inside the CGA the runway is to be considered occupied and a runway blocked FDE placed in the runway bay to reflect this.
What must an ATCO ensure before a tug requiring an escort is cleared to tow from Hangar 6 to Y1 in order to facilitate a runway crossing?
A Leader Vehicle is at Y1 for the escort
What are the R/T procedures for a Leader Vehicle escorting a towed movement across the runway?
- Leader vehicles will take R/T responsibility
- Will call AIR for crossing once both are on the correct frequency and the tug driver has been briefed
- Callsign “Leader X + 1”
Can towed movements cross the runway from any holding point if the tug crew are crossing qualified?
No. All towed crossers must use the undershoot or or Charlie. Otherwise an escort must be used.
Can AIR just place one of either the Leader Vehicle or Tug FDE in the runway bay when conducting an escorted crossing?
No. Both FDEs are to be placed in the runway bay during the crossing.
Are unescorted crossings allowed during Low Vis Safeguarding and LVPs?
Low Visibility Safeguarding - Yes
LVPs - No. All crossings during LVPs shall be under escort.
Are multiple lineups from A and M allowed?
Yes if A is instructed to line up first, and M to line up behind.
What are the AIR ATCO actions in the event that an aircraft or vehicle is lost on the manoeuvring area?
If RIMCAS is serviceable
* Take-offs and landings may continue.
* Runway inspection should be requested to confirm that the runway is not obstructed.
If RIMCAS is not in use
* It must be assumed that the aircraft or vehicle is on the runway
* No take-offs or landings are to be permitted until it can positively be established that the lost traffic no longer presents a hazard to runway movements.
What are the actions if a RET is unavailable?
- Advise landing aircraft
- Cancel lead off lights
- Select the TUBs
What are the actions in the event that GAL issue a short-notice runway closure?
- Stop Runway Movements
- Advise TC Gatwick and TC GS Airports reason and likely duration
Must ATCOs include the runway designator in RT transmissions involving the runway?
Yes.
