    Adding to above...

    Area rule is more about getting aero efficiency by drag reduction and thus reducing the apparent area of flat plate drag of a aircraft design.

    It has very little to do with the side area of the fuselage, eppenage or tail except the height of the tail. Thus not related to the volume of the rear.

    Conflating area rule to flying characteristics is not relevant.

    There seems to be more than usual Dunning-Krugers recently. I'm getting better at putting such people on ignore. Sadly, that is spoiling HBA for those are really are here to learn than to look smart.

    Never argue with a idiot, they will drag you down to their level, then beat you with experience.

    Yes Inverse Pressure Gradient Matching. I recall reading it here..was it Norman ?

    You have to see I am getting beating from everyone. But is an important factor....I think tandem seating would yield a better trainer.

    Inverse pressure gradient matching is a real thing....Mike Arnld explains it nicely. His term "poor mans area ruling " may be a bit misleading.

    Fact is that with similar size fleet Pipistrel Sinus is 15 times more safe ( 15 x less fatalities ) than an EV-97. You cannot deny this...not with Dunning-Kruger or any other "hitler-card like BS" you try to impose.

    This was one case...two died in an exercise where they tried to return to airfield after engine quit ( idle ).

    https://www.turvallisuustutkinta.fi...tutkintaselostus/b62009l_tutkintaselostus.pdf

    I flew the same maneuver with a friend of mine week after the incident with a Rallye Club ...and we had no difficulties.

    I think the EV-97 is ill suited for this kinda maneuvers.

    Rallye has proportionally bigger rudder and fuse is more streamlined all the way. It does not planket either. Also the elevator has been lifted higher...which could be a great benefit here..in regaining the flow back after a stall.

    https://en.wikipedia.org/wiki/SOCATA_Rallye_family It has way higher wing loading too.

    As I mentioned earlier, all my information is based on the US registry and US NTSB database. Not saying such accidents haven't occurred elsewhere, just that they haven't happened in the US.

    So you killed the engine without warning to the pilot to see how he responded.

    I'm guessing not.

    Without that surprise/stress factor, it isn't a fair comparison.

    I see the Finnish report you posted specifically calls out the instructor as being inexperienced, and not competent to perform the maneuver. Would you describe your friend in the same way? If not, then it's a bad comparison.

    He is very experienced and I actually did get goose bumbs for doing it, but he had it under control...during this maneuve the particular EV-97 had stalled already twice. We also have to remember that Rallye has slats and Fowler flaps. It is altogether a different kinda beast. I think my pilot friend was extremely upset and couldn't figure out why they failed...that is why he wanted to show me how elemental the move is ( in his opinion ) in a Rallye.

    I have actually also trained it with jets too in FSX...and you really have no second to loose or make a misjudgement..that is why they call it the move "impossible turn".

    I counted that new solar cells would propel sleek flying wing of 14 m span giving 11 kw....if 3 pedalled inside it might have significant add...if there are clouds or head wind etc. HPAs can only rely on 250 watts.

    I pedalled a bike 150 km last week.

    So I have a question:

    Why don't you go to the aviation authority in your country and tell them the EV-97 is deficient? You can present your evidence to them and they will quickly move to ground the airplane, no?? Certainly they will not allow a dangerous plane to fly?

    What, you mean you studied this subject in depth for years and read entire books on the theory and practice instead of reading the first result of a Google search on this one term you just heard about and mocking others for not knowing what the author renamed it to? Amateur.

    I agree... I did mention that it is a "sling" ...RITSA in finnish...and they gave me a weeks worth bananas from local aviation forum.

    Thing is that Eurostar/Sportstar is a decent aeroplane in the hands of an experienced pilot....who know how aeroplanes fly. I can fly any kite at ease in FSX. F-35 possibly the most demanding of them...and MIG-21 F13.

    Okay, that's it, I'm out of here. Quoting a flight simulation game for your aviation expertise.....

    Thank you Fergie. I wasn't sure if it was the same one or not. Mea culpa on mixing up the aircraft type.

    I assume flight simulation is the only way to fly F-35 before you actually one.
