    ok so i stop trying for this photo so just 2 question for the next pictures:
    these are my 2 big problems to see for me:
    -How can i know in which color profile i'am because when i go to color profile in my image settings photoshop say that i'am in SRGB but you say i'am not so how can i see i am in the good profile
    - second question how can i know if i have too much or too little contrast ?
    Thank you .

    First question is an easy fix. Somewhere in your work flow there is a dialog box asking you which profile to assign. One of the versions you posted was indeed sRGB, which shows that it's completely up to you and you are able to adjust this. As for contrast, that is something that is subjective, and can fall into three problematic areas: too much, too little, and unappealing (aesthetically). Most contrast issues for JP fall into the latter two categories. Too little contrast can be see when most of the image is exposed correctly, but the shadows are very weak. The last type (unappealing) is much more subjective, and usually occurs when the the light overall is very flat, and there is little difference between the subject (aircraft) and the background.

    To be frank, the contrast is terrible in all three images, and none would be acceptable.

    1, 3: terrible
    2: contrast is a bit harsh, overall a bit too dark

    As Geri is hinting at, all three would likely be dark/contrast rejections. You might want to start with an image taken in decent light before adding/subtracting contrast to make your point.

    Maybe it looks oversharpened ? but i did nothing for the sharpen during the editing this time to follow your advice.

    This would be rejected for cropping ratio, cut off, centering, and color. Contrast is the least of your worries with this image.

    Ok so this image is dead for jetphoto because a part of the elevator is cut off in the original picture, but i would like to know the cropping ratio, it's because if i take another ratio the fence is really visible, is it a problem or not ? this is the original picture:

    The chopped off elevator is a killer.

    Normaly this one compare to the other one has good croping ratio, centering, the good color profile; and any part of the plane is cut off.
    May i have your general opinion for this one ?

    Ok thank you, two questions for you:
    -Is the first obstructed by the vegetation or is it something else ?
    -How can i see that a picture is backlit, and how can i fix it ?

    Vegetation.

    If the tail is fully in shadow, then we consider it backlit. It can't be fixed.

    Ok so normally this one isn't backlit and is it obstructed by the vegetation (around the wheels) or not ?
    is it acceptable ?

    Backlit no, but obstruction likely, since it looks like it could have been avoided with better positioning/timing.

    Maybe also obstructed but the vegetation is not really on any part of the plane.

    A little question for an other one, is this angle acceptable or not ?

    Obstruction not an issue, but contrast is borderline.

    This would be rejected for Cut Off, among other things.
