Can I safely assume that Maneuver Chart "E" is incorrect? It indicates "0 - 1 - 2 - 3" turning right and "1 - 2 - 3" turning left. The rules state that a plane can not turn more than 3 hex sides.
Maneuver Chart "E" indicates 0-1-2 turning right and 1-2-3 turning left; not sure where you're getting the fourth value from on the right turn. The lesser cost for turning right reflects a rotary engine which had a tendency to pull the plane in that direction.
(I hadn't had the game off the shelf in decades, but your post roused my curiosity.)
