    but they will have to change it sooner or later…the final pak-fa will have completely different engine with different weight distribution etc….
    TsAGI is competent and will do the recalculation fast :diablo:

    I would not disagree. It just shows that the current prototype is just an YF-PAK if you want to say so.

    TVX would help as it is also useful for flight control at high speeds and also reduces the power settings at take-off- TVS for the EJ200 is more or less ready, but the customers have so far not asked for it.

    Engine inlet design is a fundamental part of the aircraft. The position of the engines is fixed and has a huge impact on the weight distribution. the inlet size and form is very important to make sure that the engine get use able air during the whole flight regime. A big redesign would mean another prototype.

    Some of the recent photos show some exposed compressor blades.

    And the MiG-29K flew in 1989? Why must every discussion always end in a pojntless contest on which fraction makes the best fighter.

    The MiG 29A or C are the versions relevant to the discussion.

    No. He is not asking for the same service. He is demanding a better service, at the same price. His weight makes him incapable of using the same service.

    BTW, 203 kg is not slightly overweight. It is grossly overweight.

    He must have eaten more than two average people to get to that weight. Were the people who sold him that food guilty of discrimination, for charging him more than they would have charged for half as much food? If I buy a cake for myself & my partner, & he buys the same cake & eats it all himself, is he discriminated against by being charged the same for his cake as we are for the cake we share?

    This is exactly the same: he weighs much more than the two of us combined, & takes up as much seating as we do between us. He should therefore pay what we pay, not half as much. If he needs two seats, he must pay for them.

    In legal terms he asks for the exact same service. And personally I think it does not address the main problem, which is safety, when you sell 2 seats to a fat person. 2 seats do not make him fall out of an emergency exit any faster.

    If they would not only sell 2 seats but also make sure that he is placed directly next to the main doors, then it would make sense and a court would be hard pressed to find a discrimination issue.

    Interestig. KLM/AF und Alitalia all operate the EMB170-195 series already, so the 20 planes ordered would be a rather small fleet. Well unless AF/KLM is planig to buy more as a replacement for the Fokker 70/100 left.

    That is discrimination. He would have to pay more for the same service, because he is slightly overweight.

    The safety issue is serious imho, but that is not solved by having those people pay more.

    To avoid discriminating people with a slightly higher bodyweight option 1 seems the best to me. Bigger seats for everybody, but also higher prices, because it would still be cheaper for those, that now are forced to buy 2 seats. So regardless of weight, skin colour or gender you would pay the same for an airline seat. And that will ne the outcome. It is happening more often and some day a slightly overweight person, like the guy, will take it to the European court for human rights and win.

    The man was not too fat, the seat was too small.

    If you say so. But there is no reliable data to prove it. In fact after Desert Storm many Soviet Air Force officers were quite surprised on how well the last generations of the AIM-7 worked.

    But even if the missile worked, the radar of the MiG-29A has so much problems keeping tracks of beaming or receding target due to sidelobe reflections from the ground, that it is very likely to lose track anyway. Add to the fact that the radar itself does the illuminating, while the F-15 uses a wide beam illuminator, this becomes even more of a problem.

    The R Version had serious problems when used against targets flying below the launch aircraft, the T was mainly to be used in a tail chase scenario.

    And finally afaik there was some limitation to manoeuvring when the MiG-29 did carry only one R-27 and it was recommended to launch both missiles at the same time.

    But I agree that the missiles used in the African wars, were mostly not in the best condition and R-27 is not a bad missile, but closer to AIM-7F than AIm-7M.

    RCS can only be guessed for both planes. There is no reliable data.

    If the AIM-7 has a kill rate of 100% then you need only one to kill a target, but in reality, it does not, so you also need two or three AIM-7 per target so the Soviet practice was the same as the real AIM-7 kill rate will indicate, a 50% kill rate.
    So you need two AIM-7s per target as the AA-10 needs

    If the missiles would be equally good, which is doubtful. AIM-7M showed above 35% hit probability, AA-10 showed less than 20% with most sources calling it next to useless against fighters.

    Comparing a fighter by numbers is pointless. One would have to consider the tactical situation of a simulated engagement to draw a conclusion for exactly that type of engagement.

    I wnder why they need new fighter aircraft in the first place. Greece has enough F-16s and M2000s to go to 2020 with them.

    If we consider the actual combat use of the AA-10 especialy in conflicts over Afrca used by SU-27 and MiG-29 flown by Soviet merceneary pilots, thean the Aim-7M was a way better missiles, as it achied a 40% hit rate during Desert Storm, a percentage the AA-10 could not even dream off.
