9.) ATM- Aerodrome Control Service & Rwy In Use

Question 1

Define Aerodrome Traffic

Answer 1

All traffic on the manoeuvring area of an aerodrome and all aircraft flying in the vicinity of an aerodrome.

NOTE: An aircraft is in the vicinity of an aerodrome when it is in, entering or leaving an aerodrome traffic circuit.

Question 2

Define Air Traffic

Answer 2

All aircraft in flight or operating on the manoeuvring area of an aerodrome.

Question 3

Aerodrome control

Answer 3

Aerodrome Control shall issue information and instructions to aircraft under its control to achieve a safe, orderly and expeditious flow of air traffic with the objective of preventing collisions between:
- AC flying within the designated AoR of the tower, including AD traffic
- AC Operating on the Manoeuvring Area
- AC Landing and taking off
- AC & vehicles operating on the Manoeuvring Area

Question 4

What shall the Aerodrome controller maintain?

Answer 4

Continuous watch on all flight operations on and in the vicinity of an aerodrome, as well as vehicles and personnel on the manoeuvring area.

Watch shall be maintained by;
- visual observation
- augmented in low visibility conditions by an ATS surveillance system when available.

Question 5

Where is final

Answer 5

Within 4nm

Question 6

When are Aerodrome control towers responsible for alerting service?

Answer 6

• An aircraft accident has occurred on or in the vicinity of the aerodrome.
• Information is received that the safety of an aircraft which is or will come under the jurisdiction of the aerodrome control tower may have or has been impaired.
• Requested by the flight crew.
• When otherwise deemed necessary or desirable

Question 7

What factors are taken into consideration when selecting the runway to use?

Answer 7

• Surface wind speed and direction
• Aerodrome traffic circuits,
• The length of runways
• Approach and landing aids available.

The most suitable for types of aircraft expected to
land or take-off at the aerodrome.

Question 8

Noise abatement shall not be a determining factor in runway nomination under the following circumstances:

Answer 8

A pilot-in-command, prompted by safety concerns, can refuse a runway offered for noise-preferential reasons.

The runway surface conditions are adversely affected (e.g. by snow, slush, ice, water, mud, rubber, oil or other substances)
• For take-off when the visibility is <1900m (Approx. 1Nm)
• Windshear has been reported or forecast
• Thunderstorms are expected to affect the approach or departure areas
• Crosswind gusts exceeds 15 knots
- Tailwind gusts exceeds 5 Knots

When the ceiling is lower than 500 ft above aerodrome elevation; or the visibility is less than 1900m
• When the approach requires use to be made of vertical minima greater than 300ft AAL and:
i. the ceiling is lower than 800ft above aerodrome elevation
i.) the visibility is less than 3000 m

Question 9

When will alerting service start?

Answer 9

Aircraft which fail to report after having been handed over to an aerodrome control tower OR Having once reported, cease radio contact
AND
Fail to land five minutes after the expected landing time.

ATCO SHALL
Be reported to the approach control unit, Area Control Centre (ACC) or to rescue co-ordination centre or rescue sub-centre, in accordance with local instructions
