NAV CANADA has discontinued the publication of AIR 5099 Alaska Highway VNC.

The final publication of the chart was the 38th edition, effective 26 December 2024.

All aeronautical and topographic information currently available on the Alaska Highway VNC will continue to be portrayed on the following VFR charts:

· AIR 5021 Atlin VNC

· AIR 5022 Fort Nelson VNC

· AIR 5028 Whitehorse VNC

· AIR 5029 Fort Simpson VNC

Purpose 

The VNC series of 52 charts is intended for VFR navigation throughout Canada. It satisfies the requirements of visual air navigation for operations at/or below 12,500 feet ASL. 

It provides for:

• Pre-flight planning:
  • 1.1 Drawing track lines and using magnetic variation information to determine track in °M;
  • 1.2 Map reconnaissance to locate major features (cities, roads, railways, etc.) for lateral navigation; and
  • 1.3 Establishing vertical flight profiles with reference to terrain and obstacle elevations.
• In-flight navigation:
  • 2.1 Determining horizontal position relative to desired track with reference to ground features;
  • 2.2 Determining distances, especially to destination;
  • 2.3 Identifying aerodromes, waypoints, frequencies, airspace boundaries, etc.; and
  • 2.4 Determining vertical position relative to obstacles and terrain

Limitations 

This map series is subject to the following limitations:

1. Due to the scale of this chart (1:500,000), it should not be used for flight in low ceiling and visibility conditions. As a guide, the lowest weather minima established in TC AIM RAC Figure 2.7 is 1000 feet AGL ceiling and 1 mile visibility in uncontrolled airspace; use of the 1:500,000 VNC series in such conditions is not advisable.
2. Not all obstacles will be shown - it is impracticable to guarantee all obstacles have been included.
3. Not all geographical or aeronautical features can be shown.
4. Due to the long chart update intervals (one, two or five years) some aeronautical information may not be current. Each VNC chart shows, under the title, the date of that edition, the date to which topographical data are corrected and the effective date of airspace amendments. New information (obstructions, restricted and advisory areas, revised control zones, etc.) is initially advertised by NOTAM or AIP Supplement, then published in the CFS and ultimately incorporated in a chart revision; and
5. The VNC contains less aeronautical information than the VFR Terminal Area Chart (VTA). Users are therefore asked to use VTA charts where available.

It is essential that users understand the purpose and limitations of this product and use it only as intended.
