Checking In on a New Frequency After a Handoff

The call that says "I made it to the new frequency" — short, required, and one new pilots forget. Here is exactly what to say and why the altitude matters. · 5 min read

On any flight where you are talking to radar controllers — flight following, a Class C or B arrival, or an IFR flight — you will be handed from one controller to the next as you move through their airspaces. Each time, the handoff sounds the same: "Skyhawk Five-Two-Kilo, contact Approach on one-two-five-point-seven." You read back the frequency, switch, and then you must check in with the new controller. Checking in is a tiny call, but forgetting it is one of the most common new-pilot mistakes: you switch, hear other traffic, assume the new controller already sees you, and stay quiet — while the new controller is waiting to hear from you before they will work you.

The check-in call

Tell the new controller who you are and your altitude. That is the whole job — your callsign lets them find your data block, and your altitude lets them verify their equipment is reading you correctly:

🎙 You say “Approach, Skyhawk Five-Two-Kilo, with you, level 4,500.”

Callsign + current altitude. Short and complete.

If you are climbing or descending, say what you are doing instead of "level": "Skyhawk Five-Two-Kilo, leaving 3,000 for 5,000." This tells the controller not just where you are but where you are going.

Why the altitude matters so much

The altitude in your check-in is a safety cross-check. The controller compares the altitude you report to the altitude your transponder is sending them (Mode C). If they match, great. If they do not, it flags a possible equipment problem before it causes a separation error. That is why "with you" alone is not enough — the altitude is the useful part.

What not to do

Do not switch frequencies and go silent, assuming you will be noticed. And do not swing the other way and launch into a long story about your flight — the new controller just needs your callsign and altitude to take responsibility for you. Anything more clogs a frequency that may be busy. Short and standard is professional.

💡 "With you" and "checking in" mean the same thing — either is fine, and both simply precede your callsign and altitude. Build the reflex: the instant you switch to a new controller, your next transmission is your check-in.

💡 The only way this becomes automatic is saying it out loud, dozens of times, before you key a live mic. That is exactly what ATCpal is for — practice the switch-and-check-in so it becomes automatic after every handoff. Practice it free at atcpal.app.
