Altimeter Setting Transition Altitude QNH and QNE

Below the Transition Altitude, you have to use as an Altimeter reference the Pressure at the Mean Seal Level also called QNH. • Two Aircraft departing from 2 different airports will use the QNH, however, this value changes from one place to another depending on the Pressure on that area. • So, if you depart from an airport with a specific QNH you must change constantly the altimeter pressure reference in order to keep the Mean Sea Level as a reference. • As you can imagine this is not an easy task. • The Transition Altitude has been established in order to provide you with a clear and specific Altitude where you have to change from the Sea Level Pressure to the Standard Pressure of 1013 hpa also called QNE. • By selecting the QNE you will use the same pressure reference of all the other Aircraft flying above the Transition Altitude. • Using the QNE as a reference you will be flying FLIGHT LEVELS and not Altitudes because you are not using the QNH as a reference anymore. • Why don't we use the QNE all the time then? • Well, you need to use the Mean Sea Level Pressure as a reference until you are clear of terrain. • The terrain is expressed in Elevation which, uses the Mean Sea Level as a reference. • If you want to separate yourself from the obstacles you need to use the same reference. • So, When you take off you must use the QNH until the Transition Altitude then changes to QNE and fly FLIGHT LEVELS. • You can find the QNH from the Atis, metar, ATC. • The Transition Altitude is indicated on the AIP, ATC, ATIS, and IFR charts. • If you want to know more about IFR training watch the video below: • IFR introduction: • IFR TRAINING (Part 1) - Instrument Fl... • SIDs: • Standard Instrument Departure (SID) P... • STARs: • Standard Arrival Route (STAR) Explain... • Approach Chart: • Jeppesen Approach Plates - [Bried an ... • ============================================================== • Disclaimer: • THIS VIDEO IS FOR ENTERTAINMENT PURPOSES ONLY. • NOT FOR REAL-LIFE OPERATIONS. • PLEASE REFER TO THE OFFICIAL MANUAL AND DOCUMENTATION. • ==============================================================
