What should a pilot do when switching frequencies?

When switching frequencies, the appropriate procedure involves confirming the new frequency before making the switch. This practice is crucial for ensuring that pilots maintain clear communication with air traffic control and other aircraft. By verifying the new frequency, pilots can be certain that they are connecting to the correct channel and are able to receive the pertinent instructions and information necessary for safe operations.

This step helps prevent any miscommunication and potential safety risks, as being on the wrong frequency can lead to missed calls from ATC or other critical instructions. Additionally, it reinforces the importance of situational awareness, allowing pilots to be fully informed and prepared for what comes next.

Turning off the current frequency without confirmation could lead to disconnecting from essential communications. Switching only when instructed by air traffic control limits a pilot's ability to proactively manage their communications. Waiting until cruising altitude may not be practical or safe, as frequency changes are often necessary during various phases of flight to ensure proper navigation and safety.
