I've been flying since the mid 70s and the term has always been "line up" as a generic term to describe the process of moving out onto the runway and stopping once aligned with the runway centre line. As in, "when you line up prior to takeoff" when talking to a student. When I was flying CRJs we would use the term "line up items" to describe pre-takeoff ...

This used to be known by ATC phraseology as ‘taxiing into position’. I.e. were the aircraft is holding short of the runway safety area, ATC clearance for takeoff has been received, and the pilot release his brakes and taxis the aircraft into the runway safety area and lining up into a position to takeoff. After a fatal accident, I believe between the DC-9 ...

Takeoff Roll As per the FAA handbook (page 5-2) Takeoff roll (ground roll) is the portion of the takeoff procedure during which the airplane is accelerated from a standstill to an airspeed that provides sufficient lift for it to become airborne. And after that Lift-off is when the wings are lifting the weight of the airplane off the ...

This comes from the Cessna 172R POH and is typical of takeoff and landing performance calculations for all Cessna 172s. First off READ ALL OF THE RELEVANT NOTES IN THE PERFORMANCE SECTION of the AFM as they explain this in detail. But as an example, let’s assume we are departing Gerfield County airport in Rifle, CO (KRIL). It’s a warm spring day in ...

There are many ways to calculate aircraft performance. Some ways are entirely manual through the use of formulas. Some ways use electronic means like apps and special calculators. Some ways use pre-calculated Tables. Then there are ways that use graphs and charts. Let’s tackle the charts way. First, remember one thing. These charts are made from data ...

Can the displaced threshold be used for takeoff? The part of the runway in front of the displaced threshold must not be used for landing (it can be used from the other direction during roll-out), but it may be used for takeoff: Displaced Threshold. A displaced threshold is a threshold located at a point on the runway other than the designated ...

US airlines are extremely fuel conscious. They have software that calculates the exact throttle and flap settings required for the exact length of runway available so that they don't burn any more fuel than necessary, and that is all typically computed before they even push back from the gate. If the pilots know in advance (e g. from the ATIS) that ...

I fly them with a fair bit of regularity, then again I fly a PA-28 out of various Class D and C airports so my takeoff requirements are usually well under the available runway. Sometimes if you are in line behind a jet waiting for their IFR release the tower may give you a VFR departure in front of them from an intersection. They say pilots are foolish for ...
