I don't think all aircraft have canopies that open.
I'm still fussing with key assignments I can't enjoy the sim until I can actually fly in it without both hands and feet trying to operate even the basic of functions

It seems to do anything you must have at least three hands one for the joystick, one for the keyboard and one for the mouse and then you must be a contortionist just to try and attempt many of the key arrangements not too mention the capacity to remember all of them all while trying to fight the baddies, rediculous

"Ctrl-Alt-Z-Shift-T-5" all just too scratch your head or other parts

Which is why I'm trying to set it up to fly like FS9, can do almost anything I want with the joystick and minimal amount of keyboard giving me time to fly and fight instead of looking down to see what code I need to type in to raise my flaps
