| 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.
