1. Many countries also use the millibar or hectopascal to give aviation altimeter settings . 2. Normally, pilots are given a current altimeter setting when they first contact approach controllers. 3. As for flight levels, the minimum flight level assigned depends on the local altimeter setting . 4. The altitude transmitted is pressure altitude, and corrected for altimeter setting at the ATC facility. 5. However, the altimeter setting at Candler Field on the morning of February 26 was 28.94. 6. The incorrect altimeter settings may have caused this descent to continue below the published decision height. 7. :Because of that weather changes, the altimeter setting is NOT the same as the barometric pressure. 8. The altimeter setting window of the sensitive aircraft altimeter is named the " Kollsman window " after him. 9. Altimeter setting messages should be sent on their own and not included in other messages to avoid confusion.10. Some Q codes are also used in aviation, in particular QNE, QNH and QFE, referring to certain altimeter settings .
