Subject field(s)
  • Cartography
  • Air Navigation Aids
CONT

Canadian Pilotage Charts are designed primarily for visual navigation and are most useful during flights at lower altitude and at slower speeds. Canadian Pilotage Charts have been replaced by VFR [Visual Flight Rules] Navigation Charts for the southern and some northern regions of Canada and for the Arctic Islands. They are still used in some northern areas of continental Canada but most hang glider pilots will probably never see one. They have a scale of 1 : 500, 000.

OBS

[This chart type] is based on the transverse Mercator projection.

OBS

Canadian Pilotage Chart (CPC): term and abbreviation used at Natural Resources Canada - Earth Sciences Sector.

CONT

Les cartes canadiennes de navigation à vue servent principalement à la navigation à vue et durant les vols à basse altitude et à faible vitesse. Chaque carte représente une partie du Canada et est appelée par le nom des principaux repères de la carte. Les cartes canadiennes de navigation à vue sont basées sur la projection de Mercator transverse et sont conformes aux caractéristiques de cette projection.

CONT

The second part of the measurement of altitude consists of measuring the amount which the object is above the altitude set on the 10 degrees scale. In order to do this the observer rotates the slow motion knob till the object and the bubble are in coincidence. When this is done he pulls the starting lever and maintains coincidence until a shutter cuts off the light from the sun, or in the case of a star the bubble illumination is switched off.
