Welcome to the NAV CANADA Aviation Weather Web Site (AWWS).

The NAV CANADA Aviation Weather Web Site (AWWS) provides flight-planning capability via the Internet for your convenience. This capability includes aviation weather, NOTAM and electronic flight plan filing applicable to flight operations within Canadian Domestic Airspace.

This Internet service is not a full, interpretive briefing. Prior to flying, pilots are encouraged to obtain an interpretative weather briefing and all pertinent NOTAM from the Flight Information Centre (FIC) in their region by calling 1-866-WX-BRIEF.

If you want to learn more about how to use this web site, please click on the User's Guide button above.

If you want to start using the site now, click on the Weather and NOTAM tab in the banner above.

To file a flight plan online, click on the File a Flight Plan tab in the banner above.

Further information on the particular page you are using is available by clicking on the Tips tab in the banner

The AWWS is constantly undergoing upgrades and changes, so check this site regularly for new features and updates on planned improvements.

[March 2007]

An "AWWS News" window has been added to the website just below the NAV CANADA banner. This window provides important, current information about website outages, planned service interruptions, new products and pertinent aviation notices. It is recommended that website users frequently check the "AWWS News" window.

[January 2007]

In November 2005, the terms (and only the terms) employed for NOTAM on the Aviation Weather Web Site were modified to better reflect and explain the complicated Canadian NOTAM System. The wording has been changed to match the AIM (MAP 5.6.8) file names:
3 files:
   - Aerodrome NOTAM file (old name: Aerodrome)
   - FIR NOTAM file (old name: FIR)
   - National NOTAM file (old name: Head office)

Also, the new term "Local NOTAM only" was introduced to emphasize the fact that it is not a file. It is only an Aviation Weather Web Site option.

Finally, the "VFR" and "IFR" options, in the route data page were changed to "Corridor" and "Waypoint" respectively, so that you can understand better what the web site system automatically retrieves. This way you can cognitively choose which NOTAM you need for a particular flight or aircraft instead of the system arbitrarily deciding what's needed for a specific flight rule.

The additonal changes done this month are:

- A complete automatic retrieval of FIR NOTAM file in "Route data": once you have selected "FIR NOTAM", the system will now retrieve all FIR NOTAM for your route even if you only choose the "waypoint NOTAM" option.

- "Aerodrome NOTAM file" option has been added to Route and Local Data selection menus

- CZNB NOTAM file option has been added for Arctic radio and International Air Frequencies

- The selection pages have been redesigned for easier access to the information.

Note: You can find more details in the "tips" section or user's guide of the website.

[November 2006]

Local Graphic Forecast (LGF)

A new graphic weather product has been added: The Local Graphic Forecast (LGF). It describes the most probable weather conditions (clouds, weather and low level turbulence) expected to occur between the surface and 10,000 feet over a given area at a specific time (the valid time) only.

The "look and feel" of the LGF is similar to the GFA; however, it does NOT replace the GFA.

Our first LGF product is the West Coast VFR LGF which has been designed to meet the needs of the Pacific coastal aviation community under Visual Flight Rules (VFR) only: 3 distinct embedded areas covering the entire Pacific coast of British Columbia. They comprise of the North Coast, Central Coast and South Coast domains.

Also, a description of the sea state over open seas is provided.

The West Coast LGF is a VFR product; therefore, icing in clouds is NOT included.

This new product can be found under the "Graphical Weather Products" section in the Forecasts and Observations page.
