From Mayday to Crosscheck: 15 Air Traffic Control Terms Every Flyer Should Know

Ever travelled in a plane and heard the pilot say something that sounded serious, like “Mayday” or “Crosscheck”? These phrases are more than just cool lingo. They’re actual Air Traffic Control terms that carry meaning, urgency, and safety cues. 

Whether you’re a nervous flyer or just plain curious, here’s your behind-the-scenes guide to what pilots, crew, and air traffic controllers are really saying.

Flight Crew Announcements: Communications & Clearances 

1. Roger That – Got It!

When a pilot says “Roger,” it doesn’t mean “yes.” It simply means the message was received and understood. Pilots use it to confirm that they’ve heard the instruction clearly and will follow it, but it doesn’t show agreement or permission—just that the message got through.

2. Wilco – Will Do!

“Wilco” is short for “Will Comply.” It means the pilot has received the instruction and confirms they’ll follow it without hesitation. This phrase shows both understanding and a promise to act. It’s used when quick, clear action is needed.

3. Affirmative / Negative – Clear Way to Say Yes or No

In aviation, clarity is everything. Simple words like “yes” and “no” can sound too similar or get lost in radio static. To avoid any confusion, pilots use “Affirmative” to say yes and “Negative” to say no. These clear words help keep communication safe and exact.

4. Cleared for Takeoff – Let’s Go!

When the tower says “Cleared for takeoff,” the pilot gets the green light to go. It means the runway is clear and everything is safe for departure. As soon as the pilot hears it, the engines roar to life and the plane starts moving. It’s the final message before leaving the ground—no more waiting, just go!

5. Final Approach – Almost There

When a pilot says “Final approach,” it means the plane is lined up with the runway and getting ready to land. This is the last stage of the flight, just moments before touchdown. It’s a signal that everything is set for arrival. It’s also the perfect time to glance out the window and enjoy the view one last time.

Note: This is what pilots say before landing.

6. Go-Around – Take Two

Sometimes, landing isn’t safe because of bad weather, traffic, or other issues. When that happens, the pilot doesn’t take a risk. Instead, they loop around and try again. This move is called a go-around. It’s a smart and safe choice, not a mistake.

In-flight safety procedures & Checks

7. Crosscheck – Safety Mode On

You’ll often hear “Doors armed” before takeoff or landing. This means the crew has checked all the doors and made sure they’re set for an emergency. It ensures the inflatable slides will automatically deploy if needed. It’s a key part of keeping everyone safe on board.

8. Door Armed – Slide Ready!

When a door is “armed,” it means the emergency slide will automatically deploy if the door is opened. This setup is essential during takeoff and landing, just in case a quick evacuation is needed. It helps prepare the aircraft for any emergency exit situation.

9. Holding Pattern – Flying in Circles

When air traffic is heavy, planes may enter a holding pattern. This means they fly in circles at a set altitude near the airport, waiting for their turn to land. It’s like being in a line in the sky—a safe and organized way to manage busy airspace.

Radio Communication Terms Used Mid-Flight

10. Squawk Code – The Plane’s Secret ID

Every plane is assigned a unique four-digit number called a squawk code. This code helps air traffic controllers identify and track the aircraft on radar. It’s like a name tag for planes in the sky, making sure each one is clearly recognized.

• Special emergency codes:

  • 7700 – General emergency

  • 7500 – Hijacking

  • 7600 – Radio communication failure

Interesting Fact: Squawk + Altitude = ID. These IDs help ATC track every plane clearly

11. Standby – Hold That Thought

When someone says “Standby” in aviation, it means wait for confirmation. The pilot or air traffic controller is handling something, but no action should be taken yet. It’s a way to pause without missing anything important.

12. Traffic – Another Plane Nearby

Air traffic control uses this call to warn pilots about another aircraft nearby. It helps keep a safe distance in the sky. If needed, pilots adjust their route or altitude. It’s a normal part of flying, handled calmly and smoothly by both pilots and ATC.

13. Flight Level – A Fancy Word for Altitude

Instead of saying “35,000 feet,” pilots say “Flight Level Three-Five-Zero.” It’s a standard way to report altitude above 18,000 feet. This format is clear, consistent, and used by pilots all over the world to avoid confusion during communication.

Mayday Vs Pan Pan: The Emergency Terms

Mayday is the highest level of distress—used during life-threatening emergencies like fire, engine failure, or medical crisis. It's always said three times: “Mayday, Mayday, Mayday.” When you hear this, it means immediate help is needed.

Pan-Pan is serious but not critical. Think of low fuel, a sick passenger, or a

system issue. It’s also repeated: “Pan-Pan, Pan-Pan, Pan-Pan.” It alerts ATC early—no panic, just precaution.

Fun Fact: “Mayday” comes from the French phrase m’aidez, meaning “help me.”

Why Do Pilots Talk This Way?

Using standard aviation terms saves time and prevents confusion. These phrases are understood by pilots and crews all over the world, no matter the airline or country. In the sky, a few clear words can make a big difference—and even save lives.

Fun Fact: Even You Use Pilot Terms!

Ever said:

• “Roger that” to your friend?

• “Mayday” as a joke when you were in trouble?

• “Standby” while texting?

Congrats—you’re already speaking aviation lingo!
