Q

control of surface traffic on apron

A

Aerodrome Control responsibility on the apron is limited to providing advice and
instructions to assist the prevention of collisions between moving aircraft. The apron may
be out of sight from some visual control rooms and in these circumstances any of the
following procedures, adapted if necessary to suit local conditions, may be used to control
moving aircraft:
(1) An aircraft is cleared to taxi. A second aircraft may be given taxi clearance plus
information on the position and intention of the first aircraft, with clear instruction to
“follow” or “give way” to it;
(2) An aircraft is cleared to taxi and all further requests for aircraft movement are
refused until the first aircraft comes into sight of the controller. A second movement
is then approved following the same procedures;
CAP 493
31 July 2020 Section 2: Chapter 1: Aerodrome Control - Page 7
(3) An aircraft is cleared to taxi and asked to report when clear of the apron or passing
an easily identifiable reference point. A second movement may then be cleared
subject to the known progress of the first.
10.3 Vehicles moving along a runway or taxiway shall give way at all times to aircraft takingoff, landing, taxiing or being towed, except that emergency services vehicles proceeding
to the assistance of an aircraft in distress shall be afforded priority over all other surface
movement traffic. In the latter case, all movement of surface traffic should, to the extent
practicable, be halted until it is determined that the progress of the emergency vehicles
will not be impeded. The phrase “give way” must not be used in RTF phraseology to
vehicles to resolve conflictions between vehicles and aircraft on the manoeuvring area.

Q

Pilots or vehicle drivers who are lost, or uncertain of their position, on the aerodrome manoeuvring should do what?

A
  • Stop and notify ATS unit, including their last known position
  • If aware they are on a runway and can vacate, should do so unless instructed otherwise and then stop
17
Q

The affected area behind a large aircraft with engines at ground idle can extend how far?

A

Up to 600m

18
Q

What may Surface Movement Radar be used for?

A
  • monitor the movements of aircraft and vehicles on the manoeuvring area
  • provide advice and assistance for the safe and efficient movement of aircraft and vehicles on the manoeuvring area. This should include the following:
  • Ensure that departing aircraft are lined up on the correct runway
  • Determining that a runway is clear of aircraft and vehicles
  • Ascertain that aircraft have commenced take-off run
  • Monitor the positions of traffic in order to facilitate switching of taxiway
    lighting
  • Monitor and assist emergency service vehicles when required
19
Q

What are the methods of establishing SMR identification?

A
  • Correlating position of visually observed aircraft/vehicle to SMR
  • Correlating an identified SMR position from another surveillance system source
  • Correlating SMR position to aircraft/vehicle as reported by radio
  • Correlating SMR position to aircraft/vehicle position
20
Q

When the pilot of an aircraft requests start-up or taxi clearance what information should be given?

A
  • Runway in use
  • Surface wind
  • QNH
  • Temperature (turbine engine)
  • Significant met conditions (eg RVR, temp inversion)
21
Q

When may aircraft be instructed to cross an illuminated stop bar?

A

When withdrawal of inoperable stop bars is not possible and:

  • runway or holding position and aircraft are visible to controller. Can use SMR subject MATS 2
  • phraseology used specific to the inoperable stop bar
  • any additional MATS 2 procedures used
22
Q

When may line-up instructions be issued to more than one aircraft at different points on the same or crossing runways?

A
  • during daylight hours
  • all aircraft continuously visible to aerodrome controller
  • all aircraft on same frequency
  • pilots advised of number and position of aircraft ahead in the departure sequence
  • runway characteristics do not prevent aircraft ahead from being seen
23
Q

When given “cleared for immediate take-off” what is the pilot expected to do?

A
  • taxi from holding position immediately onto the runway as commence take off without stopping the aircraft
  • if already lined up, take off without delay
  • if not possible, advise controller

Not to be given to Heavy aircraft

24
Q

When should a pilot be instructed to cancel take off clearance after commencing the take off run?

Above what speed does rejecting a take off run become unfeasible for modern jet airliners?

A

When the aircraft will be in serious and imminent danger should it continue

80kts

25
Q

When may an aircraft touchdown before a preceding aircraft has vacated the runway?

A
  • runway is long enough to allow safe separation between the aircraft, no evidence to suggest braking is adversely affected
  • during daylight hours
  • preceding aircraft is not required to backtrack in order to vacate the runway
  • controller is satisfied landing aircraft will be able to see preceding aircraft until it has vacated the runway
  • pilot of following aircraft is warned, responsibility for separation rests with this pilot
26
Q

What are the primary uses of the ATM (without CAA approval)

A
  • determine the landing order, spacing and distance from touchdown of arriving aircraft
  • assist in applying longitudinal separation for departing aircraft
  • enable the controller to confirm initial track of departure confirms with clearance
  • provide information to aircraft on the position of other aircraft in the traffic circuit or on approach
27
Q

What are the secondary uses of the ATM, when approved by the CAA?

A
  • following identification, validate SSR codes of departing aircraft and verify mode C
  • monitor progress of overflying aircraft identified by APR to ensure they do not conflict with arrivals/departures
  • establish separation between departing aircraft
  • pass traffic information
  • establish separation in the event of a missed approach
  • assist in taking corrective action when separation between arrivals is less than minima

Provided:
-Training / MATS 2 / Air/Ground exemption

28
Q

After consultation with Approach, who should aerodrome control inform for a runway change?

A
  • Aircraft
  • Aerodrome fire service
  • Contractors working on the aerodrome
  • Other agencies according to local instructions
29
Q

What actions should the Aerodrome controller take when an obstruction is believed to be present on the aerodrome

A
  • withhold take off and landing clearance when the obstruction is within the clear and graded area in the runway, or there is any doubt as to its position
  • when the obstruction is obviously outside the clear and graded area but on or in the vicinity of the manoeuvring area or apron advise pilot. Pilot’s responsibility to continue.
30
Q

What are the responsibilities of the Aerodrome Operator?

A

Responsible for decisions regarding the operational status of the aerodrome:

  • routine operational limitations, e.g. runway maintenance;
  • unforeseen hazards to aircraft operations, e.g. deteriorating surface conditions, obstructions etc.
  • closure or re-opening of the aerodrome;
  • withdrawal or return to use of runways, taxiways and associated lighting aids;
  • the revision of declared distances;
  • any marking required in connection with the above;
  • initiating NOTAM action to promulgate changes in serviceability.
