Calibration of Altimeters Under Pressure Conditions Simulating Dives and Climbs
Abstract
A method has been developed for the dynamic calibration of aneroid altimeters under conditions of rapidly changing pressures simulating pressure conditions in climbs and dives. It consists essentially in photographing under stroboscopic lifts, the altimeters and an especially desired liquid manometer, which measures the difference between the rapidly changing pressure to which the altimeters are subjected and an accurately known constant pressure. The probable accuracy of the method is about plus or minus 3 feet at low rates and plus;us or minus 10 feet at 30,000 feet per minute.
