How do you obtain a DF steer?

Obtaining a Direction Finder (DF) steer involves consulting the Canada Flight Supplement (CFS), as it provides critical information for pilots regarding navigation aids and procedures. The CFS contains details such as the location of navigational aids, their frequencies, and operational statuses, which help pilots effectively navigate and request DF services.

Using the CFS ensures that pilots access the most accurate and current information about the available DF facilities, which can be vital for navigating under instrument flight rules or when operating in limited visibility. This helps in making informed decisions about routing and safety, ensuring that pilots can communicate their needs effectively to air traffic control or make navigational adjustments accordingly.

The other options may not directly provide the necessary procedural information regarding obtaining a DF steer. For example, while verbally requesting to ATC might seem feasible, it is typically essential to know which facilities are available and their operational status, which is found in the CFS. Similarly, checking VFR navigation charts might help in some navigational aspects, but they do not specifically focus on DF service availability. Calling the nearest airport could yield some information, but it lacks the comprehensive details provided in the CFS that a pilot may require.
