I'm in the process of vectorizing all the charts in the PA-28-161
Warrior III POH. I am mostly doing it to make it easier on me and my
students when reading them. The takeoff roll charts you almost need a
microscope to get an accurate reading, the lines are so close together.
I plan on doing all the ones in my Warrior III POH, then I'll plan on
doing the PA-34-200T manual I have, then hopefully if I can get my
hands on one, I'll do a Baron 55.

Anyways, is anyone else interested in these charts? Is there any other
service out there that does the same thing I'm doing? Here are a couple
examples of what I have so far:

If anyone has a POH with hard to read charts, and they'd like me to
vectorize them, fell free to contact me with some scans.
