Line Up and Wait, the Phraseology Change That Replaced Position and Hold, and the Words That Keep You From Sitting on an Active Runway Blind

SUMMARY: Learn what “line up and wait” means, why the FAA replaced “position and hold” in 2010, and how to stay safe on an active runway.

“Line up and wait” is an air traffic control instruction telling you to taxi onto the runway, align with the centerline in your departure direction, and stop - without a takeoff clearance. On September 30, 2010, the FAA retired the old U.S. phrase “position and hold” and replaced it with “line up and wait” to match the international standard used everywhere else in the world. The change was driven by runway safety: harmonizing phraseology reduces confusion and helps prevent runway incursions.

What Does “Line Up and Wait” Mean?

When a controller says “line up and wait,” they want you to taxi onto the active runway, line up on the centerline pointed in the direction of departure, and then stop and hold.

You are now sitting on an active runway - but you are not cleared for takeoff. You are simply positioned and holding for a clearance that is expected to come.

Controllers use this instruction to save time and get you ready to roll. Common reasons include an aircraft on short final that will land and clear, wake turbulence spacing behind a preceding departure, or a release time they’re waiting on from the next facility.

The tradeoff is that it puts you in one of the most exposed positions in aviation: stopped on the runway, pointed down the pavement, and often unable to see traffic on final behind you.

Why Did the FAA Change “Position and Hold” to “Line Up and Wait”?

For decades in the United States, the instruction to taxi onto the runway and hold for takeoff was “position and hold.” If you learned to fly before about 2010, that phrase is burned into your memory.

The rest of the world, operating under the International Civil Aviation Organization (ICAO), had long used “line up and wait” for the exact same maneuver. The U.S. was the outlier.

Having two different phrases for the same very dangerous maneuver is a hazard - especially for international airline operations crossing borders. On September 30, 2010, the FAA harmonized with the global standard. The core purpose was runway safety and reducing runway incursions.

A runway incursion is exactly what it sounds like: an aircraft, vehicle, or person on a runway where they aren’t supposed to be, at a time they aren’t supposed to be there.

How Do I Handle “Line Up and Wait” Step by Step?

Step 1: Read it back correctly. Read back the instruction with your runway and call sign - for example, “Line up and wait, runway three one, Cessna Eight Five Xray.” Your read back is how the controller confirms the right airplane heard the right instruction. It’s a safety check, not a courtesy. Clicking the mic and saying “roger” breaks the one link in the chain that catches a mistake.

Step 2: Clear the final approach course before you roll. Physically turn your head and look down the approach path for the runway you’re about to occupy. Controllers are human and can lose track while managing several tasks at once. As pilot in command, you can often see a threat on final with your own eyes before anyone says a word.

Step 3: Wait actively, not passively. Get on the centerline, line up in the takeoff direction, and hold. Passive waiting - running flows, fiddling with the transponder, glancing at your phone - is how people get hurt. Active waiting means keeping a clock running in your head and a question on a loop: How long have I been here, and does the controller still know I’m here?

Why Is Sitting on the Runway So Dangerous?

There have been fatal collisions in aviation history that began exactly this way: an aircraft told to line up and wait (or, in the old phrasing, position and hold). Then something happens - the controller gets busy, a shift change occurs, or frequency congestion distracts them - and the controller forgets there is an airplane sitting on the runway.

That same controller then clears another aircraft to land or depart on the same runway. Now two airplanes are on one piece of pavement, and one of them was sitting still, blind, waiting for a clearance that was never given.

The FAA studied these events, which is a large part of why the read back rules are strict and the phraseology was tightened. When you’re told to line up and wait, you’ll often be given a specific reason, such as “line up and wait, traffic landing runway three one.” If there’s a traffic reason, you should hear it, and if a lengthy delay develops, the procedures call for the controller to tell you why.

Practical takeaway for your kneeboard: If you’ve been holding in position for more than a couple of minutes with no word, do not keep sitting there quietly. Key the mic: “Tower, Cessna Eight Five Xray, holding in position, runway three one.” Remind them you exist. No one has ever died because a pilot politely reminded a controller they were on the runway - the accidents run the other direction.

What’s the Difference Between Hold Short, Line Up and Wait, and Cleared for Takeoff?

These three instructions sound similar but mean completely different things:

“Hold short of runway three one” - Stop before the runway. Do not cross the hold short line; stay on the taxiway. By regulation, this instruction requires a read back that includes the runway number, every time.

“Line up and wait, runway three one” - Taxi onto the runway, line up, and stop. You are on the runway but not cleared to go.

“Runway three one, cleared for takeoff” - This, and only this, means go. Never begin your takeoff roll on anything less than the words “cleared for takeoff.” Not “line up and wait.” Not “roger.” Not a hunch.

The trap: while you’re lined up and waiting, adrenaline is up and your body wants to go. If the controller keys up to say something routine to another airplane, a primed brain can hear a clearance that was never given. The fix is a firm habit - do not move the throttle until you hear your call sign and the words “cleared for takeoff” together, in the same transmission, directed at you. If you didn’t hear your call sign, it wasn’t for you.

What Should I Do If a Landing Aircraft Goes Around?

Picture yourself number one for departure, lined up and waiting, with a Bonanza on a two-mile final. The controller is waiting for it to land and clear before sending you. Then the Bonanza balloons the landing, goes around, and now there’s a go-around happening over the top of the runway you’re sitting on.

You wait. Do not panic and firewall the throttle to get out of the way - you have no takeoff clearance and there’s an aircraft maneuvering above and ahead of you.

Hold your position, keep your eyes moving, and let the controller sort out the picture. If they need you to act, they’ll tell you. Your job is to be exactly where you said you’d be: predictable, on the centerline, waiting. The controller is building a mental model of that runway, and the worst thing you can do is become the airplane that isn’t where they think it is. Predictability is safety.

Why Standard Phraseology Matters

Radio phraseology isn’t about sounding smooth or like an airline captain. Plenty of pilots sound polished on the radio yet don’t fully understand what they’re agreeing to.

Phraseology exists so that two people who cannot see each other’s faces can build the exact same picture in their heads and agree on who is doing what, where, and when. The standard words leave no room for interpretation. “Line up and wait” now means one thing everywhere on Earth, to every controller and every pilot.

When you freelance your own words or read back “roger” instead of the actual instruction, you poke holes in the one system designed to keep two airplanes off the same slab of concrete.

You can find the phraseology itself and the read back requirements for runway hold short instructions in the FAA’s Aeronautical Information Manual (AIM), where the 2010 change is documented. Read it out loud in your airplane, on the ground, before you ever need it under pressure.

Key Takeaways

• “Line up and wait” means taxi onto the runway and stop; it is not a takeoff clearance.
• The FAA replaced “position and hold” with “line up and wait” on September 30, 2010, to align with the ICAO international standard and improve runway safety.
• Read back hold short instructions with the runway number every time, and read back line up and wait with your call sign every time.
• Only begin your takeoff roll after hearing your call sign plus the words “cleared for takeoff” in one transmission directed at you.
• If you’ve been holding in position for more than a couple of minutes in silence, key the mic and remind the controller you’re there.
