John,
yes, it should take less than a year, but we finally determined that the
tubing from the pitot mast to the instrument would have to be changed,
no easy task! He found
more than one splice in the system, which could leak at any given time (
I guess). Every time I take it for an oil change we joke about tearing
into the wing to fix it.
I have just learned to fly with it the way it is and just use it for a
reference point in all my flying. Keeps my head out of the cockpit for sure!

If closing the canopy affects the airspeed indicator (without
affecting the airspeed, of course,) then you have a leak between one
of the pitot or static systems into the cabin. The static system me
be simply vented into the cabin, but it shouldn't be. Should take
less than a year to correct...

I have the exact problem with my coupe. My mechanic hasn't been able to
fix it yet!! and thats 1 year!!! I do notice that it gets better (5
mph) when I
fly with the canopy closed. Hope you find the answer, I just fly it
by "feel"
and was taught to fly it that way by my CFI.

Thanks to everyong for all the good information.
Checking me AherSpeed" that's why I'm here.
When we bought the plane and flew it home, we were impressed by the
cruise airspeed showing 105 to 110 mph. We flew loose formation with
a Cessna 175 that we took to get the plane; he was showing 80mph with
one notch of flaps just to rub it in.
We've all noticed that if you fly the correct indicated airspeeds it
gets too slow and drops in, so we've been adding about 10 mph.
We installed a GPS in the panel, flew each cardinal heading at 100mph
indicated, GPS four way average was 88 mph (77 knots). So we are
looking for about 12 mph extra. I suspect the static system has a
problem, probably beyond the "calibration ring". We'll look at it
tonight.
We set out last evening to check out the static system and got side
tracked with the pitot ring thing, and a student preparing for a
checkride.
