In a steam driven aircraft, barometric altimeters should be preflight tested by the usual winding the subscale up and down 10mb, checking +/- 270' then checking displayed reading against a known pressure setting.
Do EFIS altimeters have to be similarly preflight tested or do they self test?
Does the CAA have a required preflight test for the purpose of instrument rating tests etc in an EFIS cockpit?
What are your standard practices in EFIS a/c?
