ARCTIC TRACK SYSTEM - In order to accommodate the flow of air traffic efficiently, in an area of few navigational aids, an Arctic Track System has been established within the Arctic Control Area (ACA), with a short extension into Alaskan airspace, to interact with the established airway system. This track system consists of four tracks (designated by phonetic letters) designed to provide lateral separation between aircraft and to facilitate the application of the Mach number technique by ATC as necessary to maintain longitudinal separation. Pilots may flight plan via these tracks at any time and are encouraged to do so if their Minimum Track Time through the ACA is close to one of the established tracks. See Canadian FLIP Enroute High Altitude Chart HE1 and inset on HE2 for depiction of the Arctic Track System.

5.
COMMONLY USED ROUTES IN WINNIPEG/MONTREAL FIRs - To alleviate convergence of traffic in the Winnipeg/Red Lake area for international flight operating between the midwest/W US and points in Europe, a system of commonly used routes is designated in Canadian Domestic High Level Airspace from 18,000’ MSL and above. These routes provide for optional flight planning over several pre-planned/fixed routes through the Winnipeg FIR to and from approximately W70° longitude in the Montreal FIR and are depicted, with their phonetic designators, on Canada FLIP Enroute High Altitude Charts HE1, 3 and 4. It is not mandatory to flight plan these routes, however, ATC may clear aircraft on the routes if traffic conditions warrant. Pilots may flight plan to or from the Winnipeg VORTAC through the Portage Military Flying Area and the Portage Military Terminal Control Area at FL330 and above.

ADDITIONAL INFORMATION
1.
MARKINGS FOR FUR AND POULTRY FARMS - Noise from low flying rotary and fixed wing aircraft can cause serious economic loss to fur and poultry farmers. Such farms are marked by chrome yellow and black watch towers on top of buildings or barns. In addition, a red flag may be flown from a low mast. Any locations so marked should be avoided with special vigilance maintained during the months of February, March, April and May.

(SPEC/RAC 1-14)

2.
MIGRATORY BIRDS AND GAME ANIMALS - All pilots flying aircraft in the North Country should realize the importance of birds/animals in relation to the native welfare and the damage (serious disorganization and broken bones) that can result when

frightened by aircraft. Therefore, diligent care should be exercised to avoid low overflight of bird nesting/harvest areas - particularly geese. When in vicinity of herds of caribou, moose, muskox or reindeer, pilots should not fly at an altitude less than 2000’ AGL with a corresponding increase for larger/noisier aircraft.
