Why should an Altimeter agree within 75ft of airport elevation?
Asked by: Steve 7530 views Commercial Pilot, Flight Instructor, Private Pilot, Student Pilot, Weather
I learned from my instrument training, and while doing my instrument cockpit check, the altimeter is to read within 75ft of airport elevation.
Aviation weather book recommends 20ft, otherwise must be removed from service.
Does anyone have any idea why they mandate such numbers on flight ?
