Refer to the Canada Flight Supplement (CFS)

The CFS is a comprehensive guide that includes details on various airports and aerodromes across Canada. It is designed to assist pilots and aviation professionals in navigating the country's airspace safely and efficiently.

When referring to the CFS, you can find specific airport frequencies listed for different regions or areas. These frequencies are used for communication between pilots and air traffic control, as well as for broadcasting essential flight information, such as wind, altitude, and runway details.

Additionally, the CFS provides information on frequency congestion and interference issues. This includes recommendations for assigning distinct frequencies for aircraft operating at different altitudes to reduce interference and improve communication effectiveness.

By consulting the relevant section of the CFS for a particular airport or region, you can identify the designated frequencies and communicate effectively with air traffic control and other pilots operating within that airspace. This ensures safe and efficient flight operations and helps maintain a clear and orderly flow of air traffic in Canada's busy airspace.

Consult the Canada Air Pilot (CAP)

To find the frequency of an airport in Canada, one of the recommended methods is to consult the Canada Air Pilot (CAP). This is an essential publication for pilots operating in Canadian airspace, and it contains comprehensive aeronautical information. The CAP is a five-volume set of publications that covers various regions across Canada, providing detailed airport information for each area.

Volume 1 of the CAP, titled "Atlantic," covers the Atlantic provinces of Canada, including Newfoundland and Labrador, Prince Edward Island, Nova Scotia, and New Brunswick. It offers detailed airport information for airports within this region. Volume 2, "Eastern," focuses on the eastern portion of Quebec and Ontario, providing airport details for major cities like Montreal and Ottawa, as well as smaller airports in the area.

Volume 3, "Central," covers the central and northern parts of Ontario, extending into the Hudson Bay region. This volume includes airport information for cities such as Toronto, Thunder Bay, and Sudbury. Volume 4, "Pacific," is dedicated to the western provinces of British Columbia, Yukon, and the western portion of the Northwest Territories. It provides airport details for cities like Vancouver, Victoria, and Calgary, as well as more remote airports in the region.

The fifth volume, "Northern," covers the northern regions of Canada, including the northern parts of Alberta, Saskatchewan, Manitoba, and the Northwest Territories, as well as Nunavut. This volume includes airport information for remote locations and high Arctic areas. Each volume of the CAP contains a wealth of information about airports within its respective region. This includes airport diagrams, communication procedures, navigation aids, and, importantly, radio frequencies used for various purposes at each airport.

By consulting the appropriate volume of the CAP for the desired airport's region, pilots and aviation enthusiasts can easily find the specific radio frequencies used for ground control, tower communication, and other aeronautical purposes. This information is crucial for safe and efficient aviation operations and is kept up-to-date through regular revisions and updates to the CAP publications.

Use the ATC-assigned frequency

To find the frequency of an airport in Canada, one method is to use the ATC-assigned frequency. This involves contacting Air Traffic Control (ATC) and requesting the frequency for a specific airport. ATC is responsible for managing air traffic in a particular region and can provide information on various frequencies used by different airports.

  • Identify the ATC Region: Canada is divided into several ATC regions, and each region has its own set of frequencies. You can start by identifying the ATC region that covers the airport you are interested in. This information can often be found on aviation charts or by contacting local aviation authorities.
  • Contact ATC: Once you know the ATC region, you can contact them via radio or telephone. Explain that you are looking for the frequency of a specific airport within their region. Provide them with the airport's name and location to facilitate their search.
  • Obtain the Frequency: After providing the necessary details, the ATC should be able to provide you with the correct frequency for that airport. Make sure to confirm the frequency and any other relevant information, such as the airport's identification code or any special instructions.
  • Verify and Cross-Reference: While ATC will provide the most up-to-date and accurate information, it is always a good idea to verify the frequency. You can cross-reference it with other sources, such as aviation charts, airport diagrams, or online databases. Websites like LiveATC.net offer live air traffic control feeds for various airports, which can help confirm the correct frequency.
  • Use the Frequency: Once you have obtained and verified the frequency, you can now use it for your intended purposes. This may include tuning your radio to that frequency for communication, navigation, or simply gathering flight information for a specific airport in Canada.

Remember that ATC frequencies can change over time, so it is essential to stay updated and consult multiple sources whenever possible. Additionally, some airports may have multiple frequencies for different purposes, such as ground control, tower control, or clearance delivery, so ensure you specify your requirements when contacting ATC.

Use an LO chart

To find the frequency of an airport in Canada, one method is to use an LO chart, which provides a graphical representation of frequencies and airport information. LO stands for Low Altitude Enroute, and these charts are part of the Canadian Domestic Enroute Instrument Proceedures (IP). They are especially useful for identifying frequencies for airports with less air traffic.

LO charts are easily accessible and can be obtained from various sources, such as online databases or aviation authorities. They are typically standard across the country, but it is essential to ensure you are referring to the correct chart for your specific region and airport.

The LO chart will provide a detailed depiction of the airspace in your area, including the frequencies used by different airports and air traffic control (ATC) services. These frequencies are crucial for communication and navigation during flight. The chart may also include additional information, such as the location of airports, runways, and other navigational aids.

To use an LO chart effectively, locate your position on the chart and identify the airport you are interested in. Find the corresponding frequency information, which is usually listed alongside the airport details. Note that frequencies may vary depending on the direction of arrival and the altitude. Cross-reference your findings with other available sources, such as airport diagrams or flight following resources, to ensure accuracy.

It is worth noting that while LO charts are beneficial, they may not always be up-to-date or cover all airports. In such cases, other resources, like the Canada Air Pilot, which includes the Calgary Instrument Approach Chart and Landing Chart, can provide more detailed information on larger airports. Additionally, online tools and databases, such as those mentioned earlier, can offer real-time frequency information for specific airports.

Use a VNC chart

VFR Navigation Charts, or VNCs, are a great way to find information about airports, heliports, airways, and aerodromes in Canada. There are 52 VNC charts published at a 1:500,000 scale that cover the entirety of Canada. These charts are designed for pilots flying at or below 12,500 feet above sea level.

To find the frequency of an airport in Canada using a VNC chart, follow these steps:

  • Locate the aerodrome symbol on the VNC chart for the airport you are interested in. The aerodrome data, including radio frequencies, is usually found within the vicinity of this symbol, often within the controlled airspace boundary.
  • For larger airports inside controlled airspace, radio frequencies may not be listed in the aerodrome data box. Instead, they will be identified in the controlled airspace stack.
  • If you are looking for the frequency of a Flight Service Station (FSS), look for a box with a heavy line. The FSS is a radio station positioned at an airport or aerodrome, providing en-route weather, traffic, and navigation services.
  • In some cases, the frequency for a centre may be found with each airport excerpt on the VNC chart.
  • If you are unable to find the frequency on the VNC chart, try using an IFR LO chart or an airport diagram from the CAP or NavCanada website, as these sources also provide airport frequencies.

It is important to note that VNC charts may not always have the most up-to-date frequency information. If you use the wrong frequency, simply contact the correct authority, and they will provide you with the right one. Additionally, you can utilise digital sources, such as ForeFlight, which offers Nav Canada VNC charts and provides access to a library of current aeronautical charts and data.
