In addition, each plane has its own specific view settings, meaning you will need to set these views for every model you will be flying if you so desire. My suggestion would be to go offline or into the Training Arena and set them first. You do not need to set them for every plane, but I would recommend picking a good 10 planes you normally fly and set the views so you are prepared when you get into the populated arenas.
Another thing to try is to play around with the views. Calculate the maximum viewing area for your specific view. Also note that sometimes the maximum amount of viewing out of the cockpit is not always the best view! Sometimes there may be a slightly better view. Try to think of where the enemy will most likely be when you are looking in that view, and not necessarily the maximum viewing area.
