Ok, I guess I should have been a little clearer with my original post. I constantly find myself pointing towards the ground (still maintaining positive vertical speed) in order to maintain a minimal air availability loss. Once I nose up, it goes from 0.1 to 0.7. Maybe it's my misunderstanding of using air breathing engines as I'm still rather new to them, I was merely suggesting possibly getting a slider that shows if you're being wasteful or being conservative.
