Ground effect

Discuss.

Please....

It should make it easier to get heavily loaded aircraft into the air before they run out of runway.

Maybe you could fly faster in it too?

After this feature was added...
Can I get excited in NOE Flight?

There are probably better people that can explain it better than me, but I'll try.

Ground effect is seen as the air being "compressed" between the ground and the wing when very near the ground as in take offs and landings.  For example, in landing, as the wing nears the ground, the air that is being deflected down due to the higher angle of attack during the flair, is "compressed" between the runway and the wing providing some small additional lift.  This effect is part of the reason some aircraft have a tendency to "float" on landing.

Ok all you aeronautical engineer types how did I do?

Thanks for the thread, Nash

Great response Sharky!

Haven't had to explain this in a number of years but as I recall, you'll find ground effect within 1.5 wing span altitude above the ground and in effect in this area you may be able to fly where otherwise you would drop like a rock.  Good for planes low on fuel, badly damaged birds etc. Any more current CFI's out there please refresh my memory.

Right on Sharky, Should see some blasting of the end of the runway on landing, but prop drag should help, also more stalls on takeoff  when in ground effect you think you are really flying and pull up into the "thin" air with low air speed, oops not enough lift.

Will this make aircraft a bit more trickier to land now?

-Westy

(and I ask myself, "self. you never land so whay are asking this...")

[Sharky]

Actually Westy I think it will make it easier to get them to sit down nice and soft.

You'll just be more prone to running outta runway.
