Departure Roll

A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.
