I've got a nifty (and accurate) EI fuel computer on the airplane and I like it, but I'd like to have a proper fuel gauge. EI makes a nice one of these as well and I've got one on the way.
Reading the manual (because I do that sometimes) it indicates that the fuel gauge must be calibrated with the aircraft in a "cruise angle of attack."
Okay. I get this. But I also know that my cruise AOA can vary a few degrees, and I also know that the -6A sits a little nose-high compared to a level flight attitude.
So what I'm wondering is just how much effect this slightly-nose-high attitude really has on the fuel calibration. Is it significant enough that I really need to consider leveling the airplane to do this?
I'm happy to do this - I'm just wondering how much error it would introduce if I didn't.
