Aerodrome Control Flashcards
What intensities of windshear should be reported?
Moderate, strong or severe
What is the ATC responsibility regarding pilot reports of moderate, strong or
severe wind shear?
Upon receipt of a pilot report and/or a forecast of moderate, strong or severe
wind shear, alert all arriving and departing aircraft by ATIS broadcast, and
directed transmission where the aircraft is not in receipt of the ATIS
information.
Continue directed transmission to other pilots until either two successive
aircraft have failed to report shear conditions or the expiry of the forecast
period, whichever is the later
What colour are taxiway side lights?
Fixed lights showing blue on both sides of the taxiway.
What colour are runway edge lights?
Runway edge lights are white, except that, in the case of a displaced threshold,
will show red in the approach direction
What are the legs in a circuit? You will be required to label a diagram.
Upwind, Crosswind, Downwind, Base, Final
(anticlockwise from take-off)
Define LAHSO
Landing And Hold Short Operations.
Allows for simultaneous arrivals and departures on intersecting runways on the provision that both pilots are aware the procedure is in use and are qualified to be an Active or Passive participant
Are aircraft operating on the apron considered to be on the manoeuvring area?
No
State 3 considerations for the selection of the runway in use
a) type of aircraft;
b) effective length of runway(s) or direction;
c) wind velocity;
d) weather phenomena, including wind gradient, wind shear, wake turbulence
effects and position of the sun;
e) in near minima conditions, availability of approach aids;
f) disposition of other traffic;
g) taxiing distances;
h) braking conditions; and
i) if workload and/or traffic conditions permit, implement ‘preferred runway’
systems in certain wind conditions to:
i) provide the optimum traffic management configuration; and
ii) comply with noise abatement procedures.
What are the conditions under which LAHSO may operate?
a) Runways are equipped with standard LAHSO signs, lights and runway
markings as specified in AIP Aerodromes (AD);
b) Cloud ceiling is not less than the highest sector MVA, as specified in local
instructions, within 8 KM (5 NM) of the aerodrome and visibility not less than
8 KM;
c) Active and passive participation is restricted to nominated runways as per
Clause 12.2.1;
d) For active participants, ground based visual or electronic glide slope guidance
is available; and
e) No wind shear is reported.
Under what conditions is a Pushback Clearance required?
The pilot in command must obtain an approval to push backwhere this
manoeuvre is necessary prior to taxiing. Information about other aircraft moving
on the same apron will be provided by the apron service.
When issuing Push-Back approval, what traffic information should be passed?
When issuing push-back approval and taxi instructions, provide traffic information on other aircraft entering, leaving or moving on the same apron.
Under what conditions must Low Visibility Procedures be implemented?
An instrument approach will take place when ceiling or visibility is less than the precision approach CAT 1 minima (must use ILS) for the runway being used
A take-off operation will take place when the runway visual range (RVR) is less than 550m for the runway being used
For a runway without precision approach:
The RVR is 800m or less
The ceiling is 200ft or less
State 3 considerations for ATC when issuing a take off clearance
a) the aircraft is at or approaching the runway in use;
b) the traffic situation permits;
c) the aircraft has reported ‘READY’;
d) a visual check of the take-off path has been completed;
e) no obstructions or collision risk exists; and
f) there is reasonable assurance that the prescribed separation standard will
exist when the aircraft commences take-off
What different callsigns may be used in a control tower and by whom?
ADC - TOWER. Aerodrome Controller, controls the runways.
SMC –GROUND. Surface Movement Controller, controls the manoeuvring area.
ACD – DELIVERY. Airways Clearance Delivery.
Coordinator assists to provide orderly traffic flow, coordinates pending departures in EUROCAT, maintains ATIS, and liaises with other units
