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 leave set on ATM?
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) To confirm that the initial track of a departing aircraft conforms with the SID 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 TI
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
- Aircraft label causing the alert is highlighted in orange on the ATM and in the AFDAS window
- The glidepath limit being breached 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
Which AFDAS alerts should be recorded in the Watch Log? And who else should be contacted after an AFDAS alert?
Those not caused by 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 on Main Runway Operations?
- MDS cooperative (transponding) targets
- Primary targets that enter the runway via a primary detection area
What is RIMCAS configiured to alert against during Northern Runway Operations?
All MDS cooperative and non-cooperative targets
When must Poor Visibility (‘Low’) 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 ATCO’s response to an aircraft declaring a TCAS RA?
“Roger”
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?
75m and 105m either side the centreline
If a vehicle has been cleared to operate inside the CGA, can the runway still be used for takeoff and landing?
No, a vehicle in the CGA occupies the runway and a runway blocked FDE shall be 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 Charlie. Otherwise an escort must be used
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.
Who shall the AIR ATCO inform when the runway becomes obstructed?
- FIN
- Sup
- GMC/GMP
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?

Yes
Should ATCOs include the holding point designator with all RT transmissions involving entering or crossing the runway?
Yes
When giving a conditional clearance behind a landing aircraft, what extra piece of information should be given about the landing aircraft?
The distance from touchdown
What should be taken into account when considering a runway change?
- Traffic already at the hold or taxiing out
- The CTOTs of departing traffic awaiting start
- Work in progress affected by a runway change
- FINs Traffic
Who makes the final decision regarding the tactical point in the traffic pattern at which the runway change occurs?
AIR ATCO after consultation with FIN
