When may IFR flights operating with visual reference to the surface be transferred by Approach Control to Aerodrome Control?

A
  1. When an ACFT carrying out instrument approach becomes ‘number 1 to land’, and for following ACFT when they are established on final approach and have been provided with appropriate separation from preceding ACFT
  2. ACFT operating in the traffic circuit
  3. ACFT approaching visually below all cloud when reported AD visibility is 10 km or more

For 2 and 3, ADC workload must be such as to allow use of one of reduced separations permitted in the vicinity of ADs

63
Q

Unless specified otherwise in MATS Part 2, responsibility for control of a departing ACFT shall be transferred from Aerodrome Control to Approach Control:

A
  1. In VMC: prior to ACFT leaving vicinity of AD, or entering IMC
  2. In IMC: Immediately after ACFT is airborne
64
Q

Restricted Operations - Responsibilities of ATC

A
  • Inform AD operator of any hazards to movement of ACFT on apron or manoeuvring area
  • If obstacle within RWY cleared and graded area or there is doubt of its position, withhold TKOF/Landing clearances and inform pilot of reason. Inform ACC
  • If obstacle on manoeuvring area, advise pilot of its position and nature. It is then pilots responsibility
65
Q

What shall contractors making repairs be briefed on by ATC?

A
  1. Methods of access to working area
  2. Area in which vehicles may operate
  3. RWY in use and effects of any changes
  4. Methods of obtaining permission to cross RWY in use;
  5. Signals or methods of indicating that vehicles and personnel must leave manoeuvring area
66
Q

Considerations for determining RWY in use

A

  • Traffic pattern
  • RWY lengths/landing runs
  • Availability of approach aids
  • Manoeuvring area serviceability
  • Aerodrome lighting
  • Weather
  • Noise abatement (not be a factor if crosswind/tailwind component, including gusts, exceeds 15 kt/5 kt respectively)

69
Q

A

ACFT taking off, landing, taxiing or being towed, except that emergency services proceeding to assist an ACFT in distress shall be afforded priority over all surface movement traffic.

N.B. Surface movement traffic should be halted so as not to impede emergency vehicles

70

Define RWY Incursion

A

Incorrect presence of an ACFT, vehicle or person on protected surface for ACFT TKOF and landing.

N.B. Protected area includes RWY strip, clear and graded area, obstacle free zone and ILS sensitive areas

71
Q

Uses of Surface Movement Radar (SMR)

A

When traffic cannot adequately be seen from control tower during low visibility or darkness to:

  1. Monitor movements of ACFT and vehicles on manoeuvring area
  2. Provide advice and assistance for safe and efficient movement of ACFT and vehicles on manoeuvring area. This should include the following:
    (a) Ensure that departing ACFT are lined up on correct RWY
    (b) Determining that a RWY is clear of ACFT and vehicles
    (c) Ascertain that ACFT have commenced TKOF run
    (d) Monitor positions of traffic in order to facilitate switching of TWY lighting
    (e) Monitor and assist emergency service vehicles when required
72
Q

Methods of SMR identification

A

By correlating:

  1. A position of visually observed ACFT/vehicle to that displayed on SMR; or
  2. An identified SMR position from another ATS surveillance system source; or
  3. A SMR position complying with an ATC instruction for a specified manoeuvre; or
  4. A displayed SMR position to an ACFT/vehicle as reported by radio; or
  5. A displayed SMR position to an ACFT/vehicle position, e.g. entering RWY or TWY, holding position or any position marked on situation display
73
Q

What is an ATIS and its contents?

A

Automatic Terminal Information Service

  • Automatic provision of current, routine information to arriving and departing ACFT throughout 24 hour period or specific portion thereof
  • Transmitted via datalink (D-ATIS) or by voice on a loop

Contents

  1. NAME of aerodrome
  2. Arrival and/or departure INDICATOR
  3. Contract TYPE, if communication is via D-ATIS
  4. DESIGNATOR
  5. TIME of observation
  6. Type of APPROACH to be expected
  7. RWY in use, status of arresting system constituting a potential hazard

  9. Holding DELAY if appropriate
  10. TRANSITION LEVEL
  11. Other ESSENTIAL operational INFORMATION
  12. Current METAR
  13. Any available information on SIGNIFICANT METEOROLOGICAL PHENOMENA in the approach and climb out areas including wind shear, and information on weather of operational significance
  14. TREND FORECAST when available
  15. SPECIFIC ATIS instructions

74
Q

A flight information service consists of…

A
  • Basic service - Provided for the purpose of giving advice and information useful for the safe and efficient conduct of flights - avoidance of other traffic is pilots responsibility
  • Traffic service - Basic service + specific surveillance derived traffic information to assist pilot in avoiding other traffic - avoidance of other traffic is pilots responsibility
  • Deconfliction service - Basic service + specific surveillance derived information and issues appropriate instructions aimed at achieving deconfliction minima - avoidance of other traffic is pilots responsibility

  • Route to be followed after TKOF
  • Minimum Departure Interval (MDI)?
  • Need to apply wake turbulence separation minima

What are the methods of measuring it?
What is the phraseology for passing it?

A

RWY Visual Range - Indicates range over which pilot of ACFT on centreline of RWY can expect to see RWY surface markings, lights delineating RWY or identifying its centreline

Made available when - METAR gives visibility of less than 1500m

Methods of reporting - Human observer method and IRVR (transmissometers - TDZ, MID and STP. 0-400m in 25m steps, 400-800m in 50m steps and 800-1500m in 100m steps

A

Responsible for decisions regarding operational status of the aerodrome in respect of:

  1. Routine operational limitations e.g. RWY maintenance
  2. Unforeseen hazards to ACFT operations e.g. deteriorating surface conditions, obstructions etc. Specifically, the Aerodrome Operator will make decisions regarding:
