I realise somewhat removed from the usual Super Cub topic.
In UK Australia if the POH does not publish a PEC for the pitot/static system we have the practice to add 50 foot to a precision ILS minima. If the POH publishes a PEC, typically either zero or 30 feet, then minima is adjusted with this figure.
The FAA has a 75 foot tolerance on the ground ramp altimeter check, and has a duty of care on altimeter errors. But does either the AIM or the Instrument Handbook define position error correction and discuss adjusting minima?
Obviously if the altimeter over reads by 75 feet there is a duty of care to consider adjusting minima?
This is not pressure error correction related to low temperature or high pressure outside the calibration (31 inches) of the altimeter.
