Wow, congratulations on the add Fabrice!
I did not doubt of the space of improvements with .RAW, I just thought the badexposure rejection is because of the not-fully pictured info on the LCD
screens of the cockpit, which is not fixable. Even in RAW.
Raw is better format right???
Yes, if you have the knowledge and the storage space.
RAW will give you more freedom with post-processing without a quality-loss like a .jpg has. Also it brings out more details of an image, that's proven.
The problem is you need quite a lot of storage space to shoot RAW all the time. E.g. if you're going to a longer journey, you will need some kind of big Image Tank or a laptop as RAW files are very big!
