It would also be nice if the heli altimeter was at sea level, like a real helicopter. It's terrible when your trying to get enough altitude to go over a mountain and you're still not high enough to get over it. You could know what altitude you needed in the first place if it was set at sea level.
I honestly wonder who like the A2G over A2S. You're supposed to look down and watch your vertical speed gauge.
It would also be nice if you could scale gauges.
