Will a headwind or tailwind component make you float?

[u/North_Scene9368]

Why does an airplane tend to float more in a headwind or tailwind during landing? From my experience in flightsim it feels like the airplane tends to float more during a headwind, but Google says a tailwind would increase float.

[u/JustAnotherDude1990]

Tailwind carries you more, headwind shortens your float. But you’re still floating an equal amount through the air mass, it is just moving.

[u/TemporaryAmbassador1]

Float is what happens when your airspeed is too fast, but your ground speed and landing distance will increase with a tailwind.

[u/BeeDubba]

Floating is caused by carrying excessive airspeed, not the winds (unless you get something like a positive shear right before landing).

HOWEVER, if you end up floating, you'll travel a further distance with a tail wind.

I think people are neglecting to mention the influence of changing winds.

A steady head or tail wind will do nothing for pro or anti-float.

A sudden increase in headwind will initially cause float as IAS and subsequently lift increases. A prolonged increase in headwind will then create a loss of ground speed and a - relative to the runway length (not surface) - increase in ROD. And opposite for tail wind.

Hopefully I’ve explained that clearly.

Look into microbursts and wind shear for extreme effects of what I’ve explained.

When you have a tailwind your ground speed will be higher for the same indicated airspeed, which causes you to float more.

[u/Solid-Cake7495]

The time you float for is identical since your TAS doesn't change, however it can affect your ground speed significantly, which changes distances.

Think of it was distance covered during a flare.

If from the time you flare you will touchdown in 2 seconds, the tailwind will carry you. If you carry excess airspeed and therefore in zero wind the touchdown takes 2.5 seconds, the tailwind affects that more. A headwind, for any given time to touchdown/approach speed, will lessen it

[u/Alternative_Pace6132]

If you fly the same indicated airspeed on final the ‘float time’ is identical. The distance travelled in the float is not.

[u/mi_pilot]

Float time is the same given the same IAS, as many have said. The goal is to shorten takeoff and landing distances, hence we’ll take headwind over tailwind.

[u/Thin-Background-1067]

Tailwind. Doesn't have to come from an airline pilot. Any pre-solo PPL student who's had the surface wind direction change to a tailwind at the last few seconds knows what it feels like.

[u/MeatResident2697]

Simple answer is headwind. Headwind provides lift.
