What is the proper way to handle a frequency switch instruction?

• A. Switch frequencies without acknowledgment.
• B. Acknowledge with your callsign after switching.
• C. Acknowledge with your callsign and switch frequencies as instructed; verify contact on the new frequency.
• D. Ask for permission to switch.

Answer: (C)

When you’re given a frequency switch, you should acknowledge with your callsign, switch to the new frequency as instructed, and then verify contact on that frequency. This sequence makes your identity and action clear to the controller and confirms you’re now listening and able to respond on the correct channel. Using your callsign in the acknowledgment helps the controller know exactly which aircraft is changing frequencies, and verifying contact ensures you’ve actually established communications on the new channel before continuing with further instructions. If you skip the acknowledgment, switch without confirming, or fail to use your callsign or verify the new contact, you risk miscommunication or losing coordination with ATC.
