    FFS, i’m happy to be shown and a link to back yourself
    some of your claims seem very wild to me, eg canards roll at a higher aoa than a hornet
    i’m quite happy with a nasa link that show aoa and roll with and without vc

    dear, dear, for someone who lives in australia you know very little
    2010 is the time for the fa-18 to replace the f-111
    2010 was never a date for the f-35
    ..typhoon was rejected because we decided the f-35 had greater capability
    ..our cost for r&d was us$144 mil
    ..we have the sourse codes we need and are working on our regional software
    ..we are commited but we havent signed as yet

    trying to roll at too high a aoa, it will drop a wing and go into a spin, they called it stalling a wing but if you want it may be loss of vortex lift on one wing
    dont tell me, show me with a link to back yourself, again its circle time, canards have higher aoa than the hornet isnt what i have read

    Do I agree about what?
    Again, you’re pushing for moot spots.

    Hornet must go beyond 1g envelope (post stall/PS) to reach alpha 55° and then it has such and such rolling ability.
    So, what we’re talking about is rolling in PS regime.
    I haven’t seen data on Rafale on that, but if I had to guess, I’d say it rolls better at same alpha, due canard position and “smoother” lift falloff after stall point, as opposed to F18.

    at 55 deg the hornet cant roll or it will stall a wing, going by what has been said it will roll at 35
    mate we go around in circles, its fun if we are taking the mickey out of each other, but you seem to be serious at the moment
    for a serious exchange, dont guess and back yourself with a link, so i can clearly understand what you mean

    TooCool
    i’ll agree with that, its as i understand it, the canards provide higher aoa over just a delta
    not real sure about it not being aerodynamic ones you may need to explain what you mean more if you dont agree with 30 and 55

    ok lets go with that, do you agree its about 30 for the euro and about 55 for the hornet

    25° is a FCS limit for F16, so no we aren’t talking about different things, although you seem to miss the concept of stall and what it means.
    Go and type in google “Stall” and spend a day or two learning flight basics.
    If you have done a good job, we won’t have this conversation anymore.

    To talk about alpha at which a plane can roll will mess things even more up, because there is no a point at which a plane can roll normally and at 1° further, it can’t roll anymore.
    The rolling ability decreases with alpha increase gradually and actual data on this are even more rare and how do you propose to discuss that when you still don’t get the concept of stall and what happens before a stall point and after?

    stall is when the wing doesnt provide lift, do you have a different definition
    http://en.wikipedia.org/wiki/Stall_%28flight%29
    what do you consider the max aoa of the planes so that i know where you are coming from

    there is a f35 thread already running and i guess you havent heard about air power australia, kopp and co

    no, the max for the f-16 is about 25-27, again we are talking 2 different things
    why dont we talk max aoa that you can roll at, its hard to mess the understanding of that up ?
    or do you just want to carry on, or can you back what you’re saying with links, then i can read what point you are trying to make

    are we talking different things ?
    the max angle of attack for a f-22 is 60-70, but it will do 110

    um, the fa18,f-35 doesnt have tv and both have about 55 deg, dont rely on your memory, show a link

    i dont remember the air speed, got a link to the 120kts ? or are you making it up
    rolling is about 2/3 of max aoa from what i was reading, or a wing could stall
    but you are more than welcome to put your view backed by links

    would you like to reread what was earlier posted and links given
    you may remember it was about 30 deg aoa for the eurocanards and 55 deg for the fa-18,35 and 60-70 for the f-22

    is there anything you dont spin ?
    the purchase cost was aud 2.9 bn with associated support systems

    do you have the extra costs to keep the f111 flying till 2025 over the fa-18f, ?
    leaving aside the extra capability that the s/hornet give us, i think it would still be cheap
