I've thought of a way to measure this. Daniel, you can measure it directly
on your friend's Ercoupe. As he has a C-90, it could also be measured on
any Forney or Alon.
For this to be accurate, the main landing gear must have had proper
maintenance so the window sills are level (fore and aft) as the plane sits
on the ground.
On a very flat tarmac, I'd measure from the ground to the top of the
windshield bow.
Then, I'd measure from the top of the windshield bow down to the cockpit
floor.
Finally, I'd measure from the cockpit floor up to the bottom of the header
tank.
In the engine compartment, I'd measure from the distance from the tarmac up
to the carburetor inlet.
Daniel, we need to know which kind of nose gear you have - the single fork
or double fork gear.
