Line Up and Wait, the Phrase That Replaced Position and Hold in Twenty Ten, and Why Two Little Words Were Changed to Stop You From Dying on the Runway

“Line up and wait” is the air traffic control instruction telling a pilot to taxi onto the runway, align with the centerline, and hold there without takeoff clearance. It replaced the older U.S. phrase “position and hold” on September 30, 2010, when the FAA harmonized American phraseology with the international ICAO standard. The change removed the word “hold” - a term so overloaded in aviation that it had contributed to deadly runway confusion.

What Does “Line Up and Wait” Mean?

When the tower issues “line up and wait,” it wants you positioned on the runway, engine ready and pointed down the centerline, but it cannot yet clear you for takeoff.

There’s usually a reason for the pause: traffic on short final that needs to clear, an aircraft still rolling out after landing, or wake turbulence separation behind a departing heavy. Rather than keeping you back at the hold short line, the controller rolls you into position so you’re ready to launch the instant the runway is yours.

It’s an efficient way to move traffic. It also puts you in a moment of genuine exposure - sitting on an active runway, in the exact spot a landing airplane wants to occupy.

Why Did the Runway Get Special Attention?

The most dangerous events at a busy airport happen on the ground, not in the air. A runway incursion is when an aircraft, vehicle, or person is on a runway where they shouldn’t be, at a time they shouldn’t be there.

The FAA tracks well over 1,000 runway incursions a year in the United States. Most are minor. But the worst is not.

The deadliest accident in aviation history, Tenerife in 1977, was two Boeing 747s colliding on a runway in fog. 583 people died - none of them flying anywhere. That history is exactly why the phrase that places you on a runway before you’re cleared to move deserves such care.

Why Was “Position and Hold” Changed?

For decades, U.S. controllers used “position and hold.” The rest of the world, under ICAO, said “line up and wait.” That mismatch created a documented, specific hazard: the word “hold.”

In aviation, “hold” is one of the most overloaded words there is:

• Hold short means stop before the runway.
• A holding pattern means fly circles in the sky.
• Hold your position on the taxiway means stop where you are.
• And “position and hold” meant taxi onto the runway and stop.

The trap is obvious once you see it. A word that usually signals stay off the runway or stop was glued onto a phrase that means get onto the runway. For a pilot who is tired, task-saturated, or flying in an unfamiliar country where English is a second language, that ambiguity was dangerous.

There were incidents where pilots heard “hold” and stopped short of the runway when the controller expected them to taxi on. And there were incidents that went the other, far worse direction. The NTSB studied a category of accident in which an aircraft told to position and hold sat waiting on the runway and was then struck - or nearly struck - by another aircraft cleared to land or depart on that same runway.

So on September 30, 2010, the FAA retired “position and hold” and adopted “line up and wait,” bringing the U.S. in line with the rest of the world.

Why Are Those Specific Words Safer?

The genius of “line up and wait” is what it leaves out: there is no “hold” in it. Nothing in the phrase can be confused with hold short or holding pattern.

“Line up” tells you the action - point down the runway. “Wait” tells you your state - you do not have takeoff clearance, and you are waiting for it. The words describe both the action and the condition, and neither can be mistaken for stay off the runway.

That’s phraseology done right. The words were chosen not to sound official, but to be hard to misunderstand when the radio is stepped on, when you’re stressed, or when you’re a student on your third solo with your heart running at 140 beats per minute.

How Do I Read Back and Use “Line Up and Wait”?

Here’s how the exchange should sound. Tower says: “Skyhawk eight five two nine X-ray, runway two seven, line up and wait.”

Your readback: “Runway two seven, line up and wait, eight five two nine X-ray.”

Read back the runway, read back the instruction, and give your call sign. Then, and only then, release the brakes and taxi into position. Once you’re there, you become the most alert person on the airport. Do three things:

1. Look. Physically turn your head and clear the final approach course. The tower is supposed to be separating you, but clear it anyway. If there’s a landing light coming down final, say something.

2. Watch the clock. Start a mental timer. Ninety seconds is a long time to sit on a runway. Controllers get busy, get distracted, or hand off the position - and there is a real accident history of an aircraft in position being forgotten while another is cleared to land on top of it. If time is passing, you hear the controller working other traffic, and your call sign hasn’t come up, speak up: “Tower, Skyhawk two nine X-ray is holding in position, runway two seven.” That one call has saved lives. An airplane sitting silently on a runway is a threat to itself.

3. Wait for the magic words. Line up and wait is not “almost cleared” and not “go when ready.” The only phrase that launches you is “cleared for takeoff.” If you didn’t hear those exact words, you’re still waiting.

Can I Decline “Line Up and Wait”?

Yes. If you’re a student or newly certificated pilot and the instruction doesn’t feel right, you are not required to accept it.

You can respond “unable,” or simply wait at the hold short line and take your clearance from there, where you can see everything. There’s no rule that forces you to accept line up and wait. Pilot-in-command authority is yours - use it.

A Real-World Scenario

You’re departing a Class Delta airport on a busy Saturday morning, flight-school traffic everywhere. You call ready, and tower says: “Three two nine X-ray, runway one seven, line up and wait, traffic landing.”

You read it back correctly, taxi into position, and clear final. Sure enough, there’s a Cherokee on a one-mile final. Good - that’s the traffic.

The Cherokee touches down and rolls. And rolls. It’s a student, slow to clear, finally turning off at the far end. Now you’ve been sitting a while, and you notice the tower is talking to a helicopter, then a Bonanza inbound, then giving someone a frequency change. Your call sign hasn’t come up.

This is the moment. Don’t sit there politely. Key the mic: “Tower, three two nine X-ray still holding in position, one seven.” Nine times out of ten the controller comes right back with your clearance. That tenth time is the one you just kept out of an NTSB report.

How Does This Show Up on a Checkride?

The Airman Certification Standards (ACS) has no task literally called “line up and wait,” but it runs through the communication and airport-operations areas.

The examiner is watching for correct, complete radio readbacks - especially of runway assignments and hold short instructions - and runway incursion avoidance is called out specifically. When you’re taxiing and talking, the examiner is checking whether you read back your runway, know exactly where you are on the field, and understand the difference between hold short, line up and wait, and cleared for takeoff. Nail those three and you’ve demonstrated real airmanship.

The Bigger Lesson About Phraseology

Standard radio phraseology isn’t about sounding like an airline captain. Every standard phrase was chosen - and sometimes changed - because the old way got someone hurt.

Say again instead of “repeat.” Affirmative instead of “yeah.” Line up and wait instead of “position and hold.” When you use the standard words, you’re standing on decades of hard lessons so you don’t have to relearn them the hard way. Talk like the book, and the whole system understands you instantly.

Key Takeaways

• “Line up and wait” means taxi onto the runway and hold in position - but you do not have takeoff clearance until you hear “cleared for takeoff.”
• The FAA replaced “position and hold” with “line up and wait” on September 30, 2010 to match the ICAO standard and eliminate the dangerously overloaded word “hold.”
• While in position, actively clear final, watch the clock, and speak up if you’ve been waiting too long - around 90 seconds is already a long time.
• You may decline line up and wait and hold behind the line instead; pilot-in-command authority is yours.
• Standard phraseology exists because ambiguous wording has killed people - using it correctly is a safety tool, not a formality.
