-Timely instructions to prevent collisions and enable safe, orderly and expeditious flight within and IVO ATZ.

Define Essential Aerodrome Information

Essential Aerodrome info is that concerning the AD and its associated facilities that may constitute a hazard to a particular AC, when when it is known that the AC has already received that info from other sources.

Info passed in sufficient time that AC proper use of it, and the hazards shall be identified as distinctly as possible. This may include provision of urgent info passed during AC take-off and landing runs.

Essential Aerodrome Information shall include: (9)

-WIP on man’ area

-Rough/broken portions of man’ area (marked or not)

-Bird formations or individual large birds

-Info on Arrester Gear.

Who has right of way, vehicles or aircraft?

Aircraft, except that EMG vehicles proceeding to an AC in distress shall be afforded priority over all other surface movement traffic.

Do not use phrase ‘give way’ for conflictions involving AC and vehicles on the man’ area.

Define Runway Incursion

Any occurrence at an aerodrome involving the incorrect presence of an AC, vehicle or person on the protected area of a surface designated for AC landing and taking-off.

Actions for a lost AC or vehicle on the Man’ area?

Stop, and ask ATC for help and state last known position. If they recognise they are on a runway, they should vacate first before seeking help.

When a pilot requests start the following information shall be given: (5)

1. Rwy in use

2. Surface wind

3. QNH

4. Outside air temp (for turbine AC)

“Runway 16 land after the Twin-Otter, G-HO”.

Criteria for issuing conditional clearance for the active runway:

-Both vehicle/AC visual to controller

-Relate to one movement only (ref. landing aircraft, first to land only, but can be given for one ahead in the departure sequence (queuing ahead)

-In both cases no ambiguity must exist as to the identity of the AC concerned.

Multiple Line-up criteria? (5)

1. Daylight hours

2. All AC continuously visible to controller

3. All AC same freq’

4. Pilots advised how many ahead departure sequence and location

5. Rwy doesn’t render proceeding AC invisible to succeeding AC on Rwy.

A departing AC shall not be given instruction which require it to turn before it has reached a height of:

500 ft. This need not apply in the case of a light aircraft.

What should an ATC clearance be prefixed with to prevent a premature departure?

“after departure”.

When “cleared for immediate take-off”, it is expected that pilots will act as follows: (3)

1. At holding position, taxi immediately on to runway and commence take-off without stopping the AC (not given to HEAVY or SUPER)

2. If already lined-up, take-off without delay

3. If immediate take-off not possible, advise the controller.

What is the usual speed/distance that a pilot can abandon a take-off?

80 Kts/300 m

2. Descend to circuit height in the dead side

3. Cross upwind end of Rwy-in-use at circuit height

4. Position accordingly into the existing Tx pattern and report downwind.

If the Rwy-in-use is occupied by AC/vehicles, an approaching AC that has requested a low app’ or touch and go, may be cleared to carry out a low app’ restricted to a height:

not below 400ft above TH elevation.

-Pilot is to be warned of AC/Vechicle on Rwy, and AC/vehicle warned of AC making low app’

-For AC on QNH, low app’ restriction is to be based on 400 ft + TH round up to nearest 50 ft.

Rwy-in-use determined by surface wind, or 2000ft wind when surface wind light and variable.

Define:

RCR

RCAM

RWYCC

Rwy Condition Report

Used by pilots to inform AC performance calculations

Rwy Condition Assessment Matrix

Used by AD operator staff to determine correct RWYCC

Runway Condition Code (given to pilot)

Determined through assessment of:

i. % contaminant coverage

ii. Type of contaminant

iii. Depth of contaminant

iv. Surface air temp’

Define WET and STANDING WATER in terms of GRF

WET

The Rwy surface is covered by any visible dampness or water up to and including 3mm depth within the intended area of use.

Standing Water

Water depth of greater than 3mm.

How is GRF reported for grass Rwys?

-Report relates to whole surface (instead of thirds)

-RWYCC not used, instead, just the contaminant is passed, e.g. WET.

Pilot may pass information regarding the Rwy surface condition, what do you do with this info?

Under no circumstance is a controller to pass pilot’s info which suggests Rwy surface condition is better than the official report.

However,

When a pilot’s report or an observation from the VCR indicates a worse Rwy surface condition, this info is to be passed.

How to pass an unofficial GRF report?

Unofficial reports from pilot or VCR are to be prefixed with the words “Unofficial observation”.

In this case the Rwy surface condition will be advised using a single term for the entire Rwy.
