Different. Very cool. I really like the font work. Not sure it's immediately recognizable as an aviation "interest". I do like the EFIS reference though. Good stuff!
#52 Can you lightly shade the portion of the icon below the horizontal line?
Again, very cool. Aircraft in silhouette needs to be recognizable as a homebuilt. The one you are using looks like a fighter or possibly a military trainer.

You can find lots of photo of aircraft with the profile I'm after.
Also www.velocityaircraft.com for something a bit more radical.
