Adjusting FOV can help you seeing things, but a big FOV number will also twist the way you see the world around you. For AH3 it was decreased to 80 for the most common monitors, the way it is in most other flight sim games, later it was increased to what it now defaults. If you increase it to 150 you'll see your wingtips in front of you like Superman's fists and both your gunsight and the target you're aiming at through it will be farther away and smaller.
You can also use the F7, F8 and F9 buttons to temporarily change the way your hat shows the view. F1 will reset the default setting - which in turn can be modified to suit your liking.
An UP button is very useful as popeye said. I've also grown accustomed to a dedicated Front-Up button for chasing an enemy.
Play with the settings to find what suits you best. There's quite a lot you can do.
