The altimeter shall be kept at this pressure for at least 5 minutes, but not more than 15 minutes, before the test reading is taken. As you increase in altitude, the pressure goes down. Some people use an altimeter watch's scale to read the altimeter, while others use a watch's digital readout. Inversely, as you fly over an area of cooler air, the air pressure will decrease, and the altimeter will read that decreased pressure as an increase in elevation. Just type in an altitude or altimeter setting and click on Do it. B. Reading a radar altimeter is slightly more complex and you should check your specific aircrafts operating handbook to make sure you know how to read this altimeter. References.
