NORTH AND SOUTH AMERICA - CNATRA - The US Navy

intending to fly an off airway track which is parallel to and within 90
NM of High Level airways shall flight plan via airways. In the case
of CMNPS certified aircraft, the 90 NM is reduced to 60 NM.
(c) During the period from May 15 to October 15,
between the hours of 1500-0200Z++ daily, pilots intending to fly
CMNPS certified aircraft on an off airway track which is parallel to
and within 60 NM of a Northern or an Arctic Track between Flight
Levels 280 and 390 shall flight plan via an established track. (See
Preferred Routes/Tracks for explanation of the Northern Track
System).
(d) It is recognized that there are routes of flight
which cannot make use of established airways and tracks - such as
between Iqaluit (CYFB) and Resolute (CYRB) or Churchill (CYYQ)
and Yellowknife (CYZF), etc. In such cases pilots may file via the
most appropriate route. However, ATC may, when traffic
conditions warrant, clear aircraft via routes other than those flight
planned.
(2) POSITION REPORTING - Except as required over
designated compulsory reporting points, or as requested by
ATC, position reports shall be made in accordance with the
following:
(a) Flight whose track is predominantly N or S (315°
True clockwise through 045° True or the reciprocals) shall report
over fixed reporting lines coincident with each 5° of latitude N or
S of and including N65° latitude.
(b) Flight whose track is predominantly E or W (046°
True clockwise through 134° True or the reciprocals) shall report
over fixed reporting lines coincident with each 10° of longitude E
and W of and including W100° longitude, except that where 20° of
longitude will be traversed in less than 60 minutes the flight may
report over such reporting lines spaced at 20° intervals. Longitude
will be expressed in degrees only. Latitude will be expressed in
degrees and minutes.
(c) When the route of flight is within the Northern
Track System, position reports shall be made in accordance with
the reporting points depicted on the FLIP Enroute High Altitude
Charts.
(d) Flight that will penetrate or operate within the
Canada Air Defense Identification Zone shall be governed by the
requirements listed under "Security Control of Air Traffic" in
Chapter 11 of the Canada and North Atlantic Flight Planning and
Procedures.
(3) AIR/GROUND COMMUNICATION -
(a) Unless otherwise directed by ATC, flight
operating within or entering the Northern Control Area shall
establish communication with one of the following Flight Service
Stations on International HF air/ground frequency as soon as
possible: Iqaluit (CYFB), Cambridge Bay (CYCB), Churchill (CYYQ),
Winnipeg (CYWG) or Resolute (CYRB).
(b) If radio communication cannot be established or
maintained with any of these stations, position reports will be
made to the nearest available TC Flight Service Station or Military
Station, on the appropriate HF or VHF frequency.
e. WITHIN THE ARCTIC CONTROL AREA (ACA) - (Also see
"Within the Northern Domestic Airspace" above).
(NAV CANADA/GPH 204, CH 5, SEC 3)
(1) RANDOM ROUTE PLANNING -
CANADA 3-13
(a) Pilots may file random tracks (with certain
exceptions specified in paragraph (b) below) but should, as a
recommended practice, endeavor to include the preferred
established tracks in the "Additional Information" part of the flight
plan. Should it be necessary to reroute aircraft, ATC will, if traffic
conditions permit, reclear aircraft via the indicated tracks. The
route of flight should be indicated by listing sufficient geographical
points to adequately portray the intended track, identifying fixes
and turning points by stations location identification or
latitude/longitude as appropriate. Also list the significant
reporting points that fall within the requirements detailed in
paragraph (2) below.
(b) During the period from 15 May to 15 October,
between the hours of 1500-0200Z++ daily, pilots intending to fly
CMNPS certified aircraft on an off airway track which is parallel to
and within 60 NM of an Arctic Track between FL280 and 390 shall
flight plan via an established track. (See Preferred Routes/Tracks
for explanation of the Arctic Track System).
(c) Between the hours of 1400-0400Z++, aircraft
intending to fly an off airway track which is parallel to and within 90
NM of High Level airways shall flight plan via airways. In the case
of CMNPS certified aircraft, the 90 NM is reduced to 60 NM.
(d) It is recognized that there are routes of flight
which cannot make use of the relatively few established tracks in
the Arctic Control Area. In such cases, pilots may file via the most
appropriate route. However, ATC may, when traffic conditions
warrant, clear aircraft via routes other than those flight planned.
(2) POSITION REPORTING - The W141°, W115° and
W60° lines of longitude have been selected as position reporting
lines for the ACA. Flights shall report as follows:
(a) Flights traversing the ACA shall report at the
point at which the W141°, W115° and W60° lines of longitude are
crossed. If crossing the ACA N of N87° latitude, the W115°
position report is not required.
(b) Westbound flights which do not cross the W60°
line of longitude on entry or prior to entry into the ACA shall report
at their point of entry into the ACA.
(c) Westbound flights which do not cross the W141°
line of longitude prior to leaving the ACA shall report at their point
of exit from the ACA.
(d) Eastbound flights which do not cross the W141°
line of longitude on entry into the ACA shall report at their point
of entry into the ACA.
(e) Eastbound flights which do not cross the W60°
line of longitude on leaving or after leaving the ACA shall report at
their point of exit from the ACA.
(f) Northbound or Southbound flights which will not
cross the significant position reporting lines shall report at their
points of entry into and exit from the ACA.
(g) Flights operating on one of the established Arctic
Tracks shall make position reports in accordance with the
reporting points depicted on the FLIP Enroute High Altitude
Charts.
(h) Flights that will penetrate the Canada Air
Defense Identification Zone while in the ACA, may forward the
required estimated time and place of the Air Defense Identification
Zone penetration as part of their W115° longitude or Mould Bay
position report.
