Aerodromes (Law) Flashcards
What is the definition of an aerodrome?
A defined area including buildings, installations and equipment, on land or water, on a fixed or floating structure, intended to be used, either wholly or in part, for the arrival and departure and surface movement of aircraft.
What is the difference between a controlled and uncontrolled aerodrome? What would their respective call signs be?
A controlled aerodrome is any aerodrome with a tower with licensed controllers directing movements and giving clearances. Their call sign will be (location) Tower.
An uncontrolled aerodrome is any other aerodrome. If they offer flight information services, their call sign will be (location) Information, and if not, their call sign will be (location) Radio.
What is a control zone?
A controlled airspace extending upwards from the ground and/or water a defined distance, located around an aerodrome, within which ATC services are provided and aircraft must be given clearance to operate.
What is the apron?
A section of the movements area designated for the purpose of accommodating aircraft while they load or unload passengers, cargo or fuel, or receive maintenance.
What is the maneuvering area?
The area in which aircraft take off, land and taxi.
What is the movement area?
A combination of the apron and the maneuvering area.
What is the landing area?
The area where aircraft land and take off.
What is the runway?
A rectangular land area of an aerodrome for the landing and take-off run of fixed wing aircraft.
What is the shoulder? When is one mandatory?
The areas to the sides of the runway which are not intended for craft to drive on, but which must be kept clear to prevent wings hitting anything, or anything getting damaged by jets. Mandatory if the runway width is less than 60m.
What is the threshold?
The area of the runway suitable for landing (distinct from the area suitable for taking off, due to the fact that takeoff can be much steeper than landing, and therefore something off the end of the runway may constitute an obstacle for landing, where it would not for takeoff).
What is the stopway?
The clear area at the end of a runway to give the pilots a little more space in case they need to abort their takeoff.
What is the clearway?
The area beyond the stopway which must be kept clear of any obstacles. It is not suitable for driving on, but is intended as space for aircraft to climb in/above.
What is the Runway End Safety Area?
A cleared space beyond the end of the clearway, intended to provide safety for any aircraft overshooting or undershooting the runway.
What are TORA and ASDA?
TORA is the Take Off Run Available, the length of the runway available for taking off in.
ASDA is the Accelerated Stop Distance Available, which is the length of the runway plus the stopway together.
Who controls which part of an aerodrome?
The runway and air around the aerodrome are controlled by the aerodrome controller, the maneuvering area is controlled by the ground controller, and the apron is controlled by the apron controller.
What are holding points? What is significant about holding points near runways?
They are locations along taxiways which aircraft can be sent to wait at. All holding points are known to be a safe distance from any runways.
Which side of the runway is called the “live side”, and why?
The left hand side, due to the fact that this is the default side for the circuit, due to the fact that the senior pilot sits on the left. Other way is dead side.
What are the names for the different parts of the circuit?
Immediately after takeoff is “upwind”. 90 degrees left or right is “crosswind”. 90 degrees further is “downwind”. 90 degrees further is “base” also called “leg”, and finally, another 90 degrees, i.e. facing the back end of the runway now, is called “final”. More than 4 NM away is “long final”.
What does a steady green light held from the tower mean?
To air traffic, cleared for landing. To ground traffic, cleared for take-off.
What does a steady red light held from the tower mean?
To air traffic, give way to other craft and continue circling, to ground traffic, stop.
What does a flashing green light held from the tower mean?
To traffic in the air, return for landing. To ground traffic, cleared for taxi.
What does a flashing red light held from the tower mean?
To air traffic, this aerodrome is unsafe, do not land. To ground traffic, it means get clear of the landing area right now.
What does a flashing white light held from the tower mean?
To air traffic, land here and then taxi directly to apron. To ground traffic, return to apron starting point on aerodrome.
What do red pyrotechnics used by any ground unit at an aerodrome mean?
Overriding all prior clearances, do not land here.
