The level is also used for checking the washout of the flight control
surfaces as well as their travel when installed on the wing. I found the
level extremely handy to insure that my left and right tailplanes were
installed at the same incidence to one another. I found that the 0.1
degree resolution to be much more than adequate for all of the jobs.
