Gusty Winds
When gusty wind conditions are obtained from reports or observed on direct
reading instruments, issue wind direction and speed of gusts.
Altimeter:
Express altimeter settings as four-digit numbers, indicating the inches of mercury to
the nearest hundredth of an inch. Do not indicate the decimal point. Pronounce the
digits 5 and 9 as indicated in Phonetic Number Pronunciation
Direct Reading Altimeter
Use the unit’s direct reading altimeter as the primary instrument for obtaining
the local altimeter setting. At locations where the direct reading altimeter is independent of the primary
source digital barometer, verify its accuracy against the reference altimeter setting when opening the
unit, if applicable, and at least once per shift.
Aerodrome Equipment
Keep informed of the operating status of airport equipment used by aircraft or ATC.
Altimeter Setting Information:
Issue the altimeter setting as follows:
* If the setting is 28.99 or lower, or 31.00 or higher, state the setting twice…(altimeter), I SAY AGAIN (altimeter)
PIREP

Active Runway
Any runway or runways currently being used for takeoff or landing. When multiple
runways are used, they are all considered active runways.
Runway Selection
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.
Crosswind
When referring to wind conditions, a wind not parallel to the runway or the path of
an aircraft.
Tailwind
For runway operations, considered to exist whenever the surface wind exceeds an
angle of 90° to the runway used by an aircraft.
Wind direction indicator
An indicator that is in the form of a truncated cone made of fabric and that is
not less than 12 ft long and, at the larger end, not less than 3 ft in diameter, so constructed as to give a
clear indication of the direction of surface wind and a general indication of wind speed
Operating Surfaces
Issue a take-off or landing clearance to a fixed-wing aircraft, provided the operation
takes place on a runway or another approved and designated area. Taxiways may be used only in an
emergency.
If the pilot requests to land on or take off from a surface other than a runway or an approved and
designated area:
* If necessary, provide traffic and obstruction information, and control instructions.
* Inform the pilot that landing or takeoff will be at the pilot’s discretion.
Noise AbatemenT
When issuing a clearance, vectors or approving a pilot’s request, except for reasons of
flight safety, follow noise abatement procedures. Even in the absence of established procedures, avoid
clearing or directing aircraft that generate significant noise over a populated area, particularly at night
Local Operations
: Consider noise abatement requirements and other pertinent regulations before
authorizing a deviation from the designated traffic circuit.
Customer, Public, and Media Communications
Direct all media inquiries to NAV CANADA Media
Relations (1 888 562 8226). Direct inquiries from the public to the airline company or NAV CANADA
head office (1-800-876-4693).
Preferential Runway
One or more runways designated and published by the airport operator whose
selection directs aircraft away from noise-sensitive areas during the initial departure and final approach
phases of flight. Designation of preferential runways may be governed by time restrictions, weather,
runway conditions, airport layout, aircraft routings, or capacity maximization.
Wet Runway
Covered with sufficient moisture to cause it to be reflective, but not “contaminated”.
Crosswind Component
The wind speed measured in knots at angles from 20° to 90° from the runway in use that would equal the effect of a wind applied at 90° to the runway in use.
ATIS (automatic terminal information services)
The wind speed measured in knots at angles from 20°
to 90° from the runway in use that would equal the effect of a wind applied at 90° to the runway in
use.
ATIS Identification
: 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
ATIS Broadcast
If the ATIS broadcast is interrupted, inform concerned sectors/units
ATIS Format:
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 [4]
3. Weather information, including:
○ Time of weather report (METAR, SPECI) or sequence
○ Surface wind, including gusts [5][6]
○ Visibility, weather and obstructions to vision and sky condition (specify the ceiling, if applicable).[7] You
may replace this information with the term CAVOK. LAWO sites are only to include visibility and
ceiling information.
○ Temperature
○ Dew Point
○ Altimeter setting [8]
○ Pertinent SIGMETs, AIRMETs and PIREPs that include severe weather
conditions in the vicinity of the airport[9], which may be itemized or referred to
alphanumerically in the ATIS messages
○ Other pertinent weather information
ATIS Message
