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. |

Any aircraft which does a stall turn stops momentarily 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. |

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

I found no evidence on a google web/groups search. If you are flying an airplane at 60 kt IAS into a 60 kt wind you are not moving forwards or backwards. 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? -- James... www.jameshart.co.uk |
