Norwegian investigators have determined that weak altimeter procedures resulted in a Wideroe De Havilland Dash 8-300 crew’s forgetting to set and check the correct QNH pressure during an approach to ...
Aircraft altimeters measure pressure and are calibrated to a standard atmosphere (ISA), but real-world pressure and temperature deviations introduce significant errors, causing the aircraft's true ...
French investigators are highlighting the importance of validating altimeter pressure settings, after a Hop Bombardier CRJ1000 descended below the glidepath on approach to Nantes. The aircraft (F-HMLD ...
