When shall control of a departing aircraft be transferred from Aerodrome Control to Approach?
a) in VMC: before a/c leaves vicinity, or before a/c enters IMC
b) in IMC: immediately after a/c airborne
Unless MATS2 specifies otherwise
With respect to Airspace Classification what minimum services are Aerodrome ATCOs to provide?
ATCOs are to provide minimum services according to the class of Airspace that ATZ is located in.
What are the met conditions at which ATC will advise aircraft intending to operate under VFR with clearance, and request the pilot to specify the type of clearance required?
When met conditions at aerodromes in Class D airspace are either
Ground visibility less than 5km
Cloud ceiling less than 1500ft
What are the met conditions that prohibit ATCOS from issuing new VFR Clearances to aircraft?
When met conditions at aerodromes in Class D airspace are either
Ground visibility less than 5km
Cloud ceiling less than 1500ft
Except for:
Police; Helimed; Rescue; Electricity; Grid; Powerline, or Pipeline Helicopters
SAR training flights
Rail track inspection flights
As detailed in ORS4
When shall ATCOs advise pilots about LVPs?
Controllers shall advise pilots on implementation and cancellation of LVPs
Are non-radio equipped aircraft/vehicles allowed to operate on the manoeuvring area in conditions of low visibility?
No. In conditions of low visibility non-radio equipped aircraft/vehicles are prohibited from moving on the manoeuvring area, except emergency vehicles.
When should Traffic Information and instructions be passed?
When the ATCO considers it necessary, or when requested by a pilot.
What Traffic Information and instructions should Aerodrome Control provide?
GST - Generic, Specific and Timely. TI gives the gist.
Aerodrome Control shall provide:
1) Generic traffic information, e.g for VFR pilots to safely integrate
2) Specific traffic information, appropriate to the stage of flight and risk of collision
3) Timely instructions to prevent collisions and enable safe, orderly and expeditious flight.
Aircraft under Aerodrome Control shall be kept informed of what information?
Aircraft under Aerodrome Control and in receipt of information shall be kept informed of:
1) Significant changes in met and runway conditions
2) Changes in essential aerodrome information
3) Changes in the status of approach and landing aids
What is the definition of Essential Aerodrome Information?
Essential aerodrome information concerns the state of the manoeuvring area and its associated facilities that may constitute a hazard to a particular aircraft.
What should Essential Aerodrome Information include?
CRAP LAWBA - Construction, Rough, Approach Aids, Parked, Lights, Anti-Icing/De-icing, Water, Birds, Arrester Gear
1) Construction/Maintenance on the manoeuvring area
2) Rough/Broken portions of the manoeuvring area
3) Failure or irregular functioning of approach aids
4) Aircraft parked close to runways/taxiways and aircraft engine runs
5) Failure or irregular functioning of lights. (Defects passed as they have been reported, promptly and accurately)
7) In snow/ice conditions: Anti-icing/De-icing information or other contamination/sweeping/sanding of runways, taxiways and aprons
6) Water, snow, slush, ice or frost on a runway, a taxiway or an apron
8) Information on birds and any bird dispersal action
9) Information on arrester gear location and status
What movements on the airfield are subject to permission from Aerodrome Control?
Aircraft/person/vehicle movements on the manoeuvring area and aircraft movements on the apron.
What does Aerodrome Control provide to aircraft on the apron?
On the apron Aerodrome Control provides advice and instructions to assist the prevention of collisions between moving aircraft.
If the apron is out of sight, what procedures may be used to control moving aircraft?
1) An aircraft is cleared to taxi. A second aircraft may be given taxi clearance plus clear instruction to “follow” or “give way”.
2) An aircraft is cleared to taxi and all further movements are suspended until ATCO is visual with first aircraft.
3) An aircraft is cleared to taxi and asked to report when clear of the apron or an easily identifiable point
Who should vehicles give way to?
Vehicles shall give way at all times to aircraft taking-off, landing, taxiing or being towed. EXCEPT repsonding emergency services vehicles shall be afforded priority over all.
Can give way be used with regards to vehicles?
No
When should clearance to cross a runway-in-use be withheld until?
Until no confliction exists
What are the conditions for a conditional runway crossing clearance?
The conditional clearance shall relate to one movement only and contain sufficient information to enable the pilot/vehicle to identify the runway traffic. In the case of landing aircraft, it must reference the first one on approach.
Can a crossing clearance be given on a different frequency to that used by traffic arrving/departing?
No. ATCOs shall ensure the crossing instruction is on the same frequency as utilised for take-off/landing clearances.
Should the phrase “report vacated” be included when issuing a crossing clearance?
Yes. However, it may be omitted when Aerodrome Control has continuous sight of the aircraft/vehicle crossing.
When aircraft/persons/vehicles are cleared to cross/occupy a runway in use, what shall the ATCO do with the FPS strip display?
The ATCO shall display the appropriate strip/marker in the FPS Runway Bay.
Define a Runway Incursion
A runway incursion is any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for aircraft take-off and landing.
How can ATCOs help to prevent runway incursions?
ATCOs shall issue unambiguous instructions to pilots/vehicles in order to eliminate or mitigate any potential hazards arising from the aircraft or vehicle being in the wrong position.
Can ATCOs ignore jet blast and slipstream effects?
No. ATCOs must take into account the hazards of jet blast and propeller slipstream. Especially with multiple line-up clearances.
