An aeroplane that can stand still in air

As usual, Keith tries to speak as an authority and is dead wrong as
usual. I have a demonstrator video of a Su-35 stopped in mid-air
(briefly) during a difficult manouver and there are plenty of others
who have seen the Su-37 do it too.

Virtually ANY high-performance airplane can "stand still in air" for a brief
instant -- just pull it up into the vertical and reduce the power. It will
eventually stop, just prior to a brief tail slide and eventual "falling leaf"
maneuver. I've done it many times in the A-4 and A-6, and once in an F/A-18D.

OTOH, I doubt there are any airplanes out there beyond the VTOL/STOOL crowd that
can come to a controlled, sustained stop in mid air. I suspect that those doing
"difficult maneuvers" in the horizontal plane maintain at least some forward
speed throughout. Otherwise, there would be no control authority.

What is a "stall turn"?

An airplane that is stalled usually maintains significant forward speed.

If you are flying an airplane at 60 kt IAS into a 60 kt wind you are not
moving forwards or backwards.

Actually, the airplane IS moving "in air" -- it is only stopped with respect to
the ground.

Hi,
Is there an aeroplane that can stand still in mid-air ?

Harrier/AV8

I used to think that SU - 30 could do it. Is that true ?

No

Keith was probably right - the original question was SU-30 related, and
you've proved him wrong quoting the SU-35 and Su-37????

Funny, I don't recall ever having any foreward, or other, speed during a
stall turn.

You are, as usual, full of it. The Su cannot "stop" in mid- air for more
than a fraction of a second.

....and I can't remember ever performing a "stall turn." Please describe the
maneuver and its parameters.

I found no evidence on a google web/groups search.

I've seen a Tiger Moth do this for about a minute during an
unofficial display, so it's hardly high tech!

About 40 years ago a private pilot was fined for flying over
Portsmouth (UK) backwards.

I wonder what they answered when asked speed and heading?

Pull up into a vertical climb in a light aircraft and you'll
soon find out
