Controlled airspace

Engine start and taxi

Engine start AIP ENR 1.1

The pilot in command of an aircraft must request approval to start engines when the requirement is notified by:

  • ATIS
  • NOTAM
  • AIP Supplement
  • ATC or
  • ERSA.

Taxi clearance AIP ENR 1.1

Where ATIS is in operation at a controlled aerodrome, a pilot in command must obtain the ATIS prior to taxi, and advise ATC of the ATIS code when requesting taxi clearance

Pilots of civil VFR training flights should advise ‘dual’ or ‘solo’ as appropriate when
requesting clearance.

The pilot in command must obtain a taxi clearance before moving on the
manoeuvring area

The taxi clearance regulates movement on the manoeuvring area. The separation of aircraft taxiing on the manoeuvring area is a joint pilot in command and controller responsibility. Taxi clearances will contain concise instructions and adequate information so flight crew can:

  • follow the correct taxi routes
  • avoid collision with other aircraft and objects and
  • minimise the potential for the aircraft inadvertently entering a runway.

Pilots vacating a holding bay shall give way to aircraft on the taxiway.

Avoidance of collision on apron areas is a joint responsibility of the pilot in command and any assisting company ground personnel. Information about other aircraft moving on the same apron area will be provided by the ATC (where it exists as a discrete service).

An aircraft taxiing on the manoeuvring area must stop and hold at all lighted stop bars and may only proceed further when a clearance to enter or cross the runway has been received and the stop bar lights have been switched off.

A taxi instruction which contains taxi limit beyond a runway must include a ‘cross runway (number) instruction to cross that runway. When an aircraft is required to hold short of a runway intersecting the taxi route, ATC will issue a taxi instruction limit of the holding point associated with the intersecting runway.

An aircraft which has been issued with a taxi instruction limit of the holding point of a runway intersecting the taxi route, or which has been issued with an instruction to hold short of that runway must subsequently be issued with an instruction to cross runway (number).

Aircraft required to hold short of a runway must hold at the appropriate holding point for that runway, or the runway strip edge at the intersection of a crossing runway. A pilot wishing to use less than the full length of the runway available should nominate the intention when requesting the taxi clearance.

ATC may offer an intersection departure and will advise the remaining runway length, if required.

A pilot in command unfamiliar with the aerodrome should request detailed taxi instructions’.

VFR aircraft wishing to depart without submitting flight notification must provide the following information on first contact with ATC:

  • aircraft callsign and details(wait for a response from ATC)
  • destination and first tracking point
  • preferred level and
  • identification of ATIS code received.

Provision of operational information AIP ENR 1.1

ATC will supply the following information for take off:

  • runway or direction
  • wind direction and speed, QNH and, if required, temperature and/or dew point
  • a time check to the nearest half-minute—upon commencing taxi from the apron before take-off
  • the crosswind component on the runway to be used, if this equals or exceeds 8 kt for single-engined aircraft or 12 kt for multi-engined aircraft
  • the tailwind component
  • aerodrome surface conditions significant to the operation
  • known weather information
  • birds that may be a hazard to the operation and
  • maintenance work within 23 m of the runway side stripe marking.

Nomination of runways AIP ENR 1.1

ATC will nominate the runway, preferred runway or take-off direction. Where noise abatement procedures are prescribed and ATC traffic management permits, the provisions of DAP NAP will be applied. ATC shall not nominate a particular runway for use if an alternate runway is available, when:

  • the alternate runway would be preferable due to low cloud, thunderstorms and/or poor visibility
  • for runways that are completely dry:
    • the crosswind component, including gusts, exceeds 20 kt or
    • the downwind component, including gusts, exceeds 5 kt and
  • for runways that are not completely dry:
    • the crosswind component, including gusts, exceeds 20 kt or
    • there is a downwind component.
