How can you adjust an altimeter if the pressure isn't correct in the
window for the altitude? I started talking to my examiner about it on
the checkride and he said that a lot of people adjust it themselves
(not an avionics shop, etc), and he said you take the front off (I
think) and theres a screw to adjust it? The plane would be used for
VFR only...

Is there an adjustment that can be made to the encoder as well if it's
off?
