QNH and QNE Altimeter Settings - [Simulator illustration of Transition Altitude]

In this video, we are going to talk about the QNH, QNE, altimeter settings, pressure reference, and Transition Altitude.
First, you are going to see a quick refresh from yesterday's video, then we will jump into the Simulator in order to perform a practical part.
The Altimeter in order to work needs a static port and a pressure reference set by the Pilot.
The pressure reference is not fixed and changes depending on the weather and the Altimeter setting you want to use.
QNH is the pressure at the mean sea level and it is used to obtain the ALTITUDE from the Altimeter.
So, if you use the QNH as a reference and you are located over the runway the Altimeter will show you the runway elevation.
If you select a lower pressure reference, for example, from 1030 hpa to 1025 hpa your indicated Altitude will decrease even if you haven't moved at all.
This is so because the 1025hpa is above the 1030hpa pressure reference (the higher you go the lesser the pressure). The opposite is also true if you select a higher pressure reference.
In the video, I make an example of this phenomenon inside the simulator.
Once you pass the Transition Altitude you have to change from the QNH to QNE (which is the standard pressure setting of 1013hpa), so if your QNH is lower than 1013hpa your indicated Altitude will increase, and vice-versa if the QNH is higher.

Thanks for your support

Good Day Capt.... Thanks you for a clearly illusion about QNH, QNE, Radio altimeter on flight simulator. It help us easier now to understand it... Have a nice weekend.. 😎👍

[@PILOTCLIMB]

You are more than welcome!! I'm glad the video helped you!! Have a great weekend!!

[@karimgaffar]

Great explanation especially when you explain it on the simulator thx cpt

[@PILOTCLIMB]

You are welcome!! Thanks for watching!!! 👍

[@PILOTCLIMB]

Leave a comment with your answers and questions!! I will answer you soon!! Happy Landings...

[@fanoooooo6]

thanks captain , easy to understand

[@PILOTCLIMB]

I'm glad the video helped you!! Thanks for watching!

Hello captain, would you please advise which flight simulator you are using please?

[@PILOTCLIMB]

Hi, I use Xpland 11 and Prepar 3d

[@rachidammoury2978]

Hello Captain, thanks for this clear explanation.
Just a quick one, so the altitude shown on the passengers' screens is inaccurate? Since at any point during the flight, we can know the exact height from QNE but not the exact Altitude.
In this case, how's the altitude, shown on the passenger's screen, is calculated.

[@PILOTCLIMB]

I'm not sure where the passengers' entertainment system takes the info from, I guess the altitude you see there is the Flight Level, using 1013.25Hpa as a reference.

[@shafiahmedzai1553]

I have a question: if aircraft A has set a QNH and Aircraft B has set QNE and they are approaching each other in the mid air, then would the tcas assist them to avoid collusion?

[@PILOTCLIMB]

Hey, great question!! As far as I know you should still get the TCAS since this system interrogates the transponders and the transponders report the Pressure alitutdes.

[@sagardeepraj3344]

hi captain ! what is the difference between QFF AND QNH..?

[@PILOTCLIMB]

Hey, I hope you are doing great!! Very good question, the QFF is the pressure at the mean sea level (like the QNH) taking into account the temperature (not like the QNH that assumes that the temperature is the Standard). Let me know if you have more questions. 👍

[@sagardeepraj3344]

@@PILOTCLIMB thanks captain 😄

[@ishansingh1668]

4:10 the altitude will be lower.

[@PILOTCLIMB]

Hey, thanks for watching...the Altitude is higher because the QNH (in the example) is below the 1013hpa, thus the Altitude is higher than the Flight Level..
