In my humble opinion, the easiest way to shoot flight deck pictures of this nature (i.e with a large amount of the window in view, where the outside is very bright and the panel is very dark), and still get a reasonable contrast balance across the whole frame, is as follows. You need a reasonable camera to achieve this - one that allows exposure readings to be locked whilst the view reframed, and also a system that provides fill-in flash:
1. Take an exposure reading of the outside world, though the flight deck windows, making sure only the outside is in the frame and not the much darker panel. Do not take this meter reading with the flash active (see later).
2. Lock the outside exposure reading (shutter speed and aperture setting) into the camera's meter, so that the reading won't change when you re-frame the subject (see next step).
3. Active the camera's flash (internal or external) and reframe the view so that the flight deck panel is included, as well as the windows. In doing this, try to ensure that the camera's metering area is on the panel, not the daylight outside (it usually will be!). However, whilst doing this do not change, or allow the camera to change, the meter reading taken of the outside world in step (1).
4. Shoot the panel with flash, with the camera still set to the outside world shutter/aperture settings. The camera's shutter and aperture settings will be correct for the outside world, and so the outside world should be exposed correctly. If the camera's flash is worth anything at all, it will fill in flash the panel will enough light so that a correct exposure is achieved of the panel whilst still using the shutter/aperture set for the outside world.
One word of warning: when taking the reading of the outside world, do not let the camera select a shutter speed that is higher than the camera's flash sync speed or you will end up with only a partial picture. If necessary, change the exposure setting for the outside world meter reading until the shutter speed it is equal to or less than the camera's highest flash sync speed.
Hope this helps,
