the difference in the correction at the same reading for pressures decreasing and increasing. The maximum value for the instrument is about 90 feet, or 0.6 per cent of the Trm-srimrrm range, and is no doubt materially lower for the pressure element. There is remarkably little difference in the… … Instrument reading, thousand feet. Flora* S-—Scale correction of BS-Navy altimeter, corrected for air temperature. (Tern perature scale set at -Hi* C.) CONCLUSION The possibility of constructing a pressure element for altimeters which will eliminate the necessity for a variable multiplying ratio in…
