What are the rules for altimeter calibration? 9) When in-flight operating below 18,000' MSL 10) When in-flight operating above 18 ,000' MSL (FL 180) 11) When operating locally in the traffic pattern without a current altimeter setting 12) What indicated altitude would altimeter 1 display if the calibration window was set to 29.72 instead of what is currently entered

13) When flying from an area of high pressure to low pressure without re-calibrating the altimeter, how does indicated altitude compare with true altitude?
