Fixing Your Float

Some airplanes, like this Mooney, can be difficult to slow down when trying to perform a landing flare. The proper airspeed is key to preventing floating down the runway, as is anticipating ground effect.

Key Takeaways:

  • Excessive floating during landing is a common issue caused by a too-fast final approach, leading to potential nosewheel landings, bounces, and runway overruns.
  • To prevent floating, pilots should establish a stable, slower final approach, adjusting from published airspeed ranges based on aircraft weight and conditions (e.g., using short-field speeds for lighter loads).
  • Effective flare planning involves targeting a specific speed at the "fence" (e.g., 10 knots above 1.2 VSO at 50 feet AGL), then smoothly reducing power to idle and applying back pressure to decelerate and touch down.
  • Ground effect contributes to floating by reducing induced drag, making it harder for the aircraft to slow down, necessitating proper on-speed arrival with idle power and a nose-up attitude for effective deceleration.

A common problem students and rusty pilots may have with their landings involves floating down the runway, waiting for the airplane to quit flying. We’re often tempted to force it onto the runway, which can result in all kinds of mischief, including landing on the nosewheel of a tricycle-gear airplane. That’s bad, since the nosewheel isn’t designed for it, and a prop strike can occur in extreme situations.

Forcing the airplane onto the runway also can result in one or more bounces, often with increasing amplitude, leading to loss of control. You also can eat up a lot of runway while waiting for the touchdown, and may not have enough left to roll out and stop. Excessive floating right above the runway generally results from flying a too-fast final approach. It should be obvious, then, that slowing down on final is one way to fix your float. But arriving over the runway at the proper speed requires some planning, which typically should begin in the traffic pattern.
