ALTIMETER SETTING PROCEDURES - Standard
except:

1.
REGIONS DESIGNATED WITH SEPARATE PROCEDURES -Canadian Airspace is divided into two "Regions" (Altimeter Setting Region and Standard Pressure Region) to provide altimeter setting procedures most compatible with the airspace characteristics involved. For delineation and graphic portrayal of the two "Regions" see Canada and North Atlantic FLIP Enroute Low Altitude Charts and the "Planning" Section C of the Canada Flight Supplement.

2.
ALTIMETER SETTING REGION - Consists of the S region and is confined to low-level (below 18,000’ MSL) airspace, much of which is controlled. Within this region altimeters shall be set to indicate altitude above Sea Level (QNH).

a.
ARRIVALS/DEPARTURES - Set aircraft altimeters to current setting for airport being used.

b.
ENROUTE - Altimeters shall be set to the current setting of the nearest station along the route of flight or, if such stations are separated by more than 150 NM, to the setting of the nearest station to the route of flight.

3. STANDARD PRESSURE REGION - Includes all airspace over Canada at and above 18,000’ MSL plus all the low-level airspace lying outside (generally N) of the lateral limits of the "Altimeter Setting Region". The low-level portion of the "Standard Pressure Region" is characterized by the complete absence of controlled airspace. Within this region, altimeters shall be set to Standard Pressure of 29.92 Hg/1013.2 mb (QNE) and the vertical position expressed in terms of Flight Level in accordance with the following procedures:
a.
DEPARTURES - When departing from an airport within the "Standard Pressure Region", climb shall be conducted with reference to the altimeter set at the current airport setting (QNH). Immediately prior to reaching the Flight Level at which the flight is to be maintained, reset the altimeter to Standard Pressure (QNE).

b.
ENROUTE - Maintain Standard Pressure setting (QNE). All reference to altitudes shall be made using the term "Flight Level".
