Assign runways as indicated in Assigning Runways. You may suggest or approve a request for another runway provided:
- You or the aircraft gain an operational advantage
- You clearly indicate the wind direction and speed to the pilot.
Fill in the blanks:
Consider __________________ and other pertinent regulations before authorizing ___________________.

Fill in the blanks:
The ________ makes the final decision on ______________________.
The pilot makes the final decision on the acceptability of a runway.
Define ATIS
The provision, throughout the day or a specified portion of the day, of current, routine information to arriving and departing aircraft by means of continuous and repetitive recorded broadcasts.
Wet Runway
Covered with sufficient moisture to cause it to be reflective, but not 'contaminated'.
Where runway configurations are appropriate, you may use one runway for light VFR aircraft and another for heavy VFR or IFR aircraft, provided:
- The surface wind components permit the use of more than one runway
- The pilot accepts the suggested runway.
CYMR Noise abatement procedure
CFS
Noise abatement procedure: All Runways; JET AIRCRAFT - no turns below 1750 feet ASL.

When assigning the preferential runway for departures or arrivals, consider the runway condition, the crosswind component, and the tailwind component.

With the exception of ATIS-NG...
With the exception of ATIS-NG, verify the accuracy of an ATIS recording before the message is broadcast. Provide a copy of the current ATIS message to each concerned position.
Active Runway
Any runway or runways currently being used for takeoff or landing. When multiple runways are used, they are all considered active runways.
You may assign a runway with a tailwind component, provided:
- The runway is dry
- You indicate the wind direction and speed to the pilot
- The tailwind component, including gusts, does not exceed 5 knots.
CARs 602.105 - Noise Operating Criteria
No person shall operate an aircraft at or in the vicinity of an aerodrome except in accordance with the applicable noise abatement procedures and noise control requirements specified by the Minister in the Canada Air Pilot or Canada Flight Supplement, including the procedures and requirements relating to:
- Preferential runways;
- Minimum noise routes;
- Hours when aircraft operations are prohibited or restricted;
- Arrival procedures;
- Departure procedures;
- Duration of flights;
- Prohibition or restriction of training flights;
- VFR or visual approaches;
- Simulated approach procedures; and
- The minimum altitude for the operation of aircraft in the vicinity of the aerodrome.
Preferential Runway
The 2 conditions when a controller must provide ATIS even when a message is being broadcast.
- If the ATIS cannot be kept current due to rapidly changing conditions, record a message that all or part of the information will be issued by the unit.
- If the pilot does not acknowledge receipt of the current ATIS message.
Tailwind
For runway operations, considered to exist whenever the surface wind exceeds an angle of 90o to the runway used by an aircraft.
Calm-wind runways are selected due to factors such as:
- Their length
- The approach (often due to weather)
- Taxi distance
- Noise abatement

(Complete the reference)
Initial climb to at least 800 feet AAE:
- Power/thrust as set for takeoff;
- Flaps/slats in take-off configuration; and
- Climb speed not less than V2 + 10 kt.
At or above 800 feet AAE, maintain a positive rate of climb and accelerate towards Vzf, and:
- retract flaps/slats on schedule; and
- reduce power/thrust at a point along the acceleration segment that ensures satisfactory acceleration performance.
Continue the climb to 3000 feet AAE at a climb speed not less than Vzf.
At 3000 feet AAE, transition to normal enroute climb speed.

Table: Allowable Crosswind Components
Dry runway:
- Visibility:
- 1 mile or more = 25 knots
- Less than 1 mile = 15 knots
- RVR:
- 5000 feet or more = 25 knots
- Less than 5000 feet = 15 knots
Wet:
- Any = 15 knots
ATIS messages are identified with a code letter as follows:
- Assign a code letter in sequence from the phonetic alphabet, beginning with ALFA, and continuing to ZULU until all letters are used, then start a new cycle without regard to the beginning of a new day.
- If the broadcast is interrupted for 6 hours or more, assign code ALFA to the first message on resuming service.
- If two radio frequencies are used to simultaneously broadcast in both official languages, assign the same code letter and use identical message content.
- If two radio frequencies are used to simultaneously broadcast an arrival ATIS message and a departure ATIS message, assign the same code letter to both.
Crosswind Component
The wind speed measured in knots at angles from 20o to 90o from the runway in use that would equal the effect of a wind applied at 90o to the runway in use.
Benefits of assigning a longer runway for arrivals and departures.
Arrivals:
- More stopping distance available
- Less necessary reverse thrust and braking
- Less fuel consumption
- Less wear and tear on the aircraft
Departures:
- Additional runway length in the event of aborted take-off

Initial Climb to at least 800 feet AAE:
- Power/thrust as set for takeoff;
- Flaps/slats in takeoff configuration; and
- climb speed not less than V2 + 10 kt.
At or above 800 feet AAE:
- Initiate power/thrust reduction;
- Maintain climb speed not less than V2 + 10 to 20 kts; and
- maintain flaps/slats in take-off configuration.
At 3000 feet AAE:
- maintain positive rate of climb;
- accelerate to enroute climb speed; and
- retract flaps/slats on schedule.
(ATIS) Record a new message if any of the following occurs:
- A new METAR or SPECI is received
- A new LAWO observation is conducted
- An applicable SIGMET, AIRMET, or PIREP is received, updated or cancelled.
- The altimeter setting changes by +/-0.04 inches or more since the last recorded altimeter data.
- The type of IFR approach is changed.
- A runway is changed.
- An applicable NOTAM is received, updated or cancelled.
- A change in runway conditions is reported.
Keep ATIS messages concise. Do not include RVR in the ATIS message.
Include the following information in order, as applicable, in the ATIS message:
1. Aerodrome name
2. Message code letter
3. Weather information, including:
- Time of weather report (METAR, SPECI) or sequence
- Surface wind, including gusts
- Visibility, weather and obstructions to vision and sky condition (specify the ceiling, if applicable). You may replace this information with the term CAVOK. LAWO sites are only to include visibility and ceiling information.
- Temperature
- Dew Point
- Altimeter setting
- Pertinent SIGMETs, AIRMETs and PIREPs that include severe weather conditions in the vicinity of the airport, which may be itemized or referred to alphanumerically in the ATIS messages.

Wind Direction Indicator (2 definitions)
Definition 1: An indicator that is in the form of a truncated cone made of fabric, and that is not less than 12 feet long and, at the larger end, not less than 3 feet in diameter, so constructed as to give a clear indication of the direction of surface wind and a general indication of wind speed.
Definition 2: An actuated device for indicating visually to aircraft the direction of surface wind.
