Arrival Landing — Flare profile at 83 %, −0.17 points

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 21 ft off the runway centreline during the ground roll, and wing drift like that usually keeps reappearing as bank in the climb, with 3.9° of bank in the first climb segment and 3.4° 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

Arrival

Fly the flare as one continuous check of the sink rate from 9.7 ft, holding back pressure steadily rather than adjusting pitch piecemeal.

What happened: The flare drifted away from its intended profile rather than tracking it smoothly from 9.7 ft down to touchdown.

Watch for: Watch radio altitude and VSI through the flare, aiming to arrest the sink smoothly from 9.7 ft to touchdown.

See Arrival Landing

Ground control varies with speed, full authority at walking pace, progressively reducing as groundspeed rises. The aircraft becomes twitchy at any speed, every small pedal input swings the nose, which can encourage large-amplitude leg inputs that no real aircraft would accept.
