Position errors on an altimeter?
Well, yes? I understand it to mean errors due to position of pitot/static - airflow etc. So altimeter associated.
Must confess though to being motivated by wanting an exchange with the Bose! Been reading your posts for a couple of years now, and I'm a big fan! Sycophancy over, box ticked. Keep up the good work. Off flying now.
