Taxi and Line Up! Explained by Captain Joe

What is the difference between "taxi" and "line up"? Dear friends and followers today I´ll be answering another question which was sent in by one of my youtube follower .... "Joe what is the difference between Taxi and Line up?" Great question! They are two separate things, that´s for sure. So let´s imagine you´ve just fastened your seat belts and you can feel the aircraft being pushed back out of it´s gate position. The eninge spoul up and a few minutes later the aircraft starts to move under it´s own power. The pilots standby for the clear signal by the pushback driver and then request a taxi clearance with ground or apron controller, which will sound similar to this."......" After receiving the taxi clearance the pilots turn on the taxi and runway turnoff lights, release the parking brake and taxi along their assigned route. Very often you can feel the aircraft slowing down just after it started moving, that indicates a brake check, then you might see the ailerons going up and down, that is the flight control check. On smaller Turboprop jets you sometimes see that only one propeller is spinning, so the pilots are using the single engine taxi procedure. But all these procedures can vary from airline to airline. Also entering the deicing pad and getting deiced is within the taxi phase. Sometimes you have to give way for incoming or outgoing traffic, or stop at an active runway which you have to cross in order to get to your holding point. At big airports like Madrid or Los Angeles you might have to change the ground frequency up to four times and taxi times can vary between three minutes and 1 hour or even longer. To steer the aircraft you either use the tiller or the pedals once the speed is high enough, and the maximum taxi speed is 30 knots, approximately 60km/h and going around a turn should be performed at speeds not higher then 10 knots to prevent the nosewheel from colapse. So once you´ve reached your holding point at your assigned runway, the ground controller will advise you, once your leaving his perimeter, to switch over to tower control. The tower controller is in charge of overlooking the approach and departure sector and to give line up, take-off and landing clearances. The taxi phase ends once the tower controller has cleared you onto to the active runway. Before lining up, the tower controller will mostly likely ask you if you are "ready for the departure". Once you´ve completed the "Before Take-Off Checklist" you will respond, "AirJoe123, ready for departure","AirJoe123 line up runway 26Right". Once lined up, he will say,"AirJoe123, cleared for take-off runway 26right". So the line up starts once you´ve passed the holing point and ends once your airplane fuselage is in line with the runway centerline. You should be fully ready for departure cause if there is inbound traffic you do not want to line up on the runway if you´re not fully ready, possibly causing the inbound traffic to perform a go-around. No you do not want that to happen, trust me! Line ups can also be performed via runway intersections, and even if there is a airplane waiting at the beginning of the runway. There are special line up procedures, in Düsseldorf/Germany for example, a Airbus A330 or Boeing 777 will line up in the opposite direction, perform a 180 degree turn to use the full available runway lenth in case of a heavy take-off weight. Special line up guide lines will help the pilot to perform this procedure. Also there are special line up clearances, for example if you have inbound traffic on short final, like in this video, the tower controller will say "AirJoe123, BEHIND next landing Airbus A321, line up runway 26Right BEHIND". When reading back your clearance, the controller will take extra care that you mention the word "BEHIND" twice. So those are the main differences of taxi and line up. Taxi is getting to the runway and line up is entering the runway and being ready for take-off.

athatv phansikar: What is Lima and mike orders given by act for taxing? What do they stand for ? Pls can u explain sir ?

Kim-Andreas Æbelø: Hi Joe. Great videos!! I was flying 2 days ago, and when the plane taxied to the runway, i thought about: Could the plane go longer (pr liter of fuel) if it drove to my destiantion? Can you answer that? (given it could go in the same straight line of course)

Abdul hameed: the voice over radio between act and cockpit is very hard to understand...how do u guyz do it+

winni223: What actually moves planes on a tarmac when the turbines are at low speed? Electric engine(s) ?

Huy Khoa Nguyen: Hi could you please do one video in details about taxi one engine procedure? It's a well known procedure and would be great if you can share your experience with everyone here in youtube, thanks

GhostHostMemories: Line up and wait, vs Line up and Cleared for takeoff.

What's your preferred departure sequence? spool up on the runway, or hit the runway "running?"

Marcus Lin: hey captain Joe! do u fly to Singapore?

Laxmi Shrestha: very polite speqking

Laxmi Shrestha: the wheel moves with help of air or motor

Ricardo Lozano: How does, basically, the glare shield (autopilot nav) works? When to select Heading mode, VNav, etc.?

rondon123: Does anybody understand what ATCler says?

Arnab Saha: What is Automatic Asset Manager (ASM)

mediacoregroupph: is position and hold the same?

Jose Cancino: great video once again Captain

Warner Adams: Have you or any other pilot on here butchered a read back? I did for the first time yesterday and ATC had to correct me, I also missed a call all together shortly after departure later the same day. I've been beating myself up about it, since there are people's lives on the line.

nidurnevets: Will the controller ever issue a clearance for take off from the old short position, without first issuing "line up and wait?" Excellent videos

Kian Gitizad: Echt super Videos. Vielen Dank. Übrigens als ich mit einem A330 von Düsseldorf geflogen sind wir auch von der 23L gestartet hatten aber kein Special line up. Aber das hast du ja erklärt. Dann hätten wir wahrscheinlich kein hohes abfluggewicht

Alper YOLAL: My father worked as an air traffic controller for 30 years in Ankara Esenboga Airport (Turkey). And also my mother was at AIS (with the new name AIM). Now you are filling the blanks from the eye of the pilot. Great channel. Great topics. thanks
