Round-out, flare, and touchdown on a normal landing
The flare (also round-out): slow, continuous transition from glide attitude to landing attitude.
- Start 15 to 30 ft above ground.
- Keep increasing as altitude is lost, right through to touchdown.
Touchdown and after touchdown, by gear:
| Gear | Touchdown | After touchdown |
|---|---|---|
| Tricycle | Main wheels first, no weight on nose wheel | Hold nose wheel off as long as practical |
| Tailwheel | All wheels simultaneously, elevator fully back, throttle closed | Control column fully back until stopped: shorter roll, better directional control |
- Tricycle: lower nose wheel sooner only if directional control gets difficult, or in gusty or turbulent air (stops aircraft skipping or lifting off again).
- Tricycle: nose wheel settles on its own as elevator loses effectiveness. Don't hold it up with excess speed.
Keep one hand on throttle through landing: bounce needs instant power correction.
Vision:
- Primary sense here; sense of motion not developed enough to help much.
- Focus ahead of aircraft, about same distance as in a car at same speed. Closer as speed drops.
- Focus too close, or straight down: reactions abrupt or late.
Cues for judging flare point:
- Height above surface, using known objects.
- Point ground seems to rush up.
- Point whole landing surface seems to expand.
- Point ground movement suddenly becomes apparent.
Height judgement in round-out:
- Normally uses apparent speed, ground texture, size of known objects.
- Over water, snow, or in darkness those cues disappear. Judgement narrows to what is left, such as runway width alone.
Once flare has started:
- Don't push forward to fix over-controlled backward movement. Relax back pressure or hold it constant. Add a touch of throttle if speed bleeds off.
- Within 2 to 3 ft of ground: check descent with further back pressure. Close to stall, so it doesn't add height; it slows the settle for a gentle touchdown.
- Judge touchdown by aircraft's change in attitude, against landing horizon (aerodrome edge) and nose, not control column movement: as speed drops, same movement does less.
Trap: treating touchdown as the end of the job. Judging attitude and holding correct back pressure continue through the rollout, not just to the moment wheels touch.
