I had problems with my incidence gauges (warped), and I asked Mark
Machado at Velocity (when he still worked there) what the incidence
angles really were. Here is the reply:
----------
-Could not find any documentation regarding incidence angles so we
measured
the jigs. The results are as follows (the data should be considered
preliminary):
canard - 4.6 degrees positive incidence
standard wing - 0.6 degrees positive incidence
LW wing - 0.9 degrees positive incidence
The incidence angle is based on the chord line of each individual
airflow
and its relationship to a level line. Positive is above level; negative
would be
below level.
Margin of error: probably plus/minus .1 degree on each measurement.
------------
As Alex suggests; leveling the fuselage when making incidence
measurements is crucial.
FWIW,
