Next time

Departure

Make small rudder corrections against a fixed point at the far end of the runway to hold the centreline during the roll.

What happened: The aircraft drifted 9 m off the runway centreline during the ground roll, and wing drift like that usually keeps reappearing as bank in the climb, with 2.4° of bank in the first climb segment and 2.5° still showing in the second.

Watch for: Heading indicator: steady on the runway centreline during the roll, then wings level through the climb.

See Departure RollDeparture Climb 1Departure Climb 2

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.
