5) Inform AD operator when there is a deterioration in state of AD or facilities which AD responsible for.
6) initiate overdue action where no APC exists.
What shall Aerodrome Control coordinate with APC?
2 things
1) Departing IFR Flights
2) Arriving a/c that call the Tower first.
What will APC coordinate with AD Control?
1) A/C approaching to land?
2) Arriving aircraft cleared to visual holding points
3) Aircraft routing through the traffic circuit
Unless specified in MATS pt2 the responsibility for control of a departing aircraft shall be transferred from AD control to APC…..(2 times)
1) In VMC: prior to leaving the vicinity of the aerodrome or entering IMC.
2) In IMC: immediately after the aircraft is airborne.
When an AD is in class D airspace and the visibility is less than 5km and/or the cloud ceiling of 1500ft(day or night) what shouldn’t the ATCO do?
Issue any further VFR clearances to or from and Aerodrome or enter the ATZ or traffic circuit.
Aircraft under the jurisdiction of AD control and in receipt of information critical to safe operations must be kept informed of any subsequent changes such as?(3 things)
1) Significant Met changes and runway conditions.
2) Changes in essential AD information
3) Changes in operational status of approach and landing aids
What 5 things is SMR used for?
- Departing aircraft lined up on correct runway
- Determining Runway clear of a/c n vehicles
- ascertain a/c have commenced takeoff
- monitor position of traffic to facilitate switching of Taxiway lighting
- monitor and assist emergency vehicles
What 5 ways can you establish SMR identification?
1) Correlating position visually and on SMR
2) Correlating SMR Position from another Surveillance source
3) Correlating SMR Position with an ATC Instruction for a manoeuvre
4) Correlating SMR Position with Radio
5) Correlating SMR Position with Situation display
Line up Instructions may be issued to more than one aircraft at different points on the same or crossing runways provided that?
(5 things)
1) Daylight only
2) A/C continuously visible to AD ATCO
3) All a/c on same frequency
4) Pilots advised of number of a/c ahead on departure sequence n position they depart
5) Runway characteristics don’t render preceding aircraft invisible to succeeding aircraft.
When an aircraft is using the same runway, a landing aircraft may be permitted to touch down before a preceding landing aircraft which has landed is clear of the runway provided that?
(5 things)
1) Runway long enough to allow safe separation between 2 aircraft (braking not adversely effected)
2) Day light hours
3) Preceding aircraft not required to backtrack
4) ATCO satisfied the landing aircraft will be able to see preceding a/c until it has vacated the runway.
5) The succeeding aircraft is warned.
What are the 3 exemptions from separation minima in the traffic circuit?
1) A/C information to other aircraft in the same formation
2) A/C operating in different areas or lanes on ADs equipped with runways for simultaneous landings and T/Os
3) A/C operating under military necessity
The information derived from an ATM may be used for?
4 things
1) Determining Landing order, spacing and distance from touch down
2) Assist in applying Longitudinal separation for departing a/c
3) ATCO can confirm the initial track of a departing aircraft conforms with the clearance issued.
4) Provide Information to a/c on the position of other aircraft in the circuit or instrument approach.
When permitted by the CAA the ATM may also be used to?
4 things
A) following identification, validate SSR CODES of departing aircraft and verify associated Mode C read outs
B) monitor progress of over flying a/c so they don’t conflict with tracks of arriving and departing traffic
C) establish Separation between departing aircraft
D) pass traffic Information
E) establish separation for MAPt
F) assist in taking initial corrective action when separation between arriving aircraft becomes less than the prescribed minima
The ATM may be used for extra things provided that?
3 things
ATCO has undertaken specific training
ATCO is only providing an air control service and a separate ground control service is being provided by another ATCO on a separate frequency
Procedures are detailed in MATZ pt 2
What factors are considered when selecting the runway in use?
1) Traffic pattern
2) length of runway
3) Landing runs
4) approach aids available
5) met conditions
6) operations/efficiency
7) noise abatement
When is noise abatement not to be a factor in selecting a runway in use
- crosswind exceeding 15kts
- tailwind exceeds 5kts
- degree and type of runway contaminant
- minimum visibility and cloud ceiling
- other weather conditions (windshear/TS)
- pilot request another runway due safety concerns
Who should an ATCO inform when changing runways?
- Aircraft under his control
- RFFS
- contractors working in the AD effected by change
- other agencies according to local instructions
What things will the AD controller decide when the operator takes time to assess situations?
(3 things)
1) where an operational occurrence has resulted in the obstruction in the vicinity of the runway in use:
a) withhold T/O and landing clearances when within the clear and graded area
b) withhold T/O and landing clearance if there is any doubt as the position/nature of the obstruction
2) when the obstruction is obviously outside the cleared and graded area but in vicinity of apron/manoeuvring area pilot will be advised of position and nature of obstruction.
When CANT RVR Reference lights be switched off?
3 things
1) when A/C taking off
2) after and a/c has reported completing a final procedure turn
3) after a/c has reached 5 miles from touchdown on radar approach
When must AD lighting be displayed?
By night: irrespective of weather conditions
By day: whenever Visibility is less than 5km and/or cloud base less than 700ft
What needs to be done with Malicious use of lasers against aircraft?
1) Acknowledge report from Pilot
2) Seek as much information as possible:
- time of attack
- Altitude and position
- description of the laser
- any avoiding action taken
- any impact up vision/concentration
3) Anticipate need of Pilot to minimise impact on aircraft
4) Dial 999 and pass relevant information to local police
5) Warn Pilots of other aircraft in the vicinity
6) Record details in watch log and complete report
What 8 things should be done when getting effected by malicious use of lasers against ATS facilities
1) look away
2) shields eyes and lower sun blinds if possible
3) advise aircraft laser is illuminating
4) avoid rubbing eyes
5) consider increasing ambient light
6) hand over control to other ATCO
7) inform supervisor
8) record event
