WebDec 31, 2024 · Say that the 10,000-foot pointer was at the 1, the 1000-foot pointer was at the 2, and the 100-foot pointer is at the 3rd line past the 6. You would read the total altitude as 10,000+2,000+660=12,660. You are flying at 12,660 feet above sea level. 5. Look at the drum and then the pointer to read a drum altimeter.

WebTo calculate pressure altitude without the use of an altimeter, subject approximately 1 inch of mercury for every 1,000-foot increase in altitude from sea level. For example, if the current local altimeter setting at a 4,000-foot elevation is 30.42, the pressure altitude would be 3,500 feet: 30.42 – 29.92 = 0.50 in. http://learntoflyblog.com/2015/06/22/flight-instruments-the-altimeter-and-altitudes/

WebThat’s what our altimeter is set to and we’re going to leave it set to 30.00 all the way across the entire flight.
