- Welcome to another Super Sunday video, where I will explain what are the standard and most known pressure settings. There are three very crucial pressure settings like QNH, QNE and QFE. Every pilot should know what these three pressure settings mean, otherwise sit down and enjoy the video.

Finally a dead simple explanation of QNH/QNE/QFE! Well done.
Thanks nice to hear that!
@@ALL4AVIATION Agreed. Well done! I scoured the internet and CZcams trying to find a straight forward answer and yours was that. Thank you!
@@FlyingV53223 Thanks!
Thanks for the interesting and short video. Nice simulation background!
Thank you!
Thank you very much man. You helped me a lot
No problem 😉
QFE is still being used at OMSK (UNOO) in the Russian Federation. Below Transition Level they clear the flight to Meters and not feet as well.
Great, thanks for feedback! I did not know that only at some parts of Russia they still use meters below TL.
Thank you
Very handy, Gal.
Thanks
very good
Good. Just a question. Is the formula QNH=QFE+Alt(feets)/27 Correct?
Affirm that is correct. Alt(feets) should be airfield elevation.
Or maybe, QNH=QFE+ALT (feets)/28.5 Is it ?
Yep taking 28.5 is totally okay for prediction or even taking 30 should be good.
When do I press the "Approach" button before landing?
You should press the Approach button as soon as controller clears you for the ILS approach on the final track towards the runway. Or everytime when you would like to start your aircraft to follow the ILS approach. There are also other approaches which are used with Approach button but ILS is the most used one.
Is qnh altimeter? If not where can i set my altimeter
Please show in the a320
@@prestonarmy1 The QNH is the pressure setting which you need to use when below Transition altitude. That means that when you will stand at the airport the altimeter which shows the elevation will read the real elevation of the airfield. QNH is normaly defined in METAR reports and pilot setts the right QNH by rotating the knob bellow the figures defining the QNH. This knob is located left (Pilot) and right (Copilot) of the Autopilot panel. By setting the correct QNH the altimeter will change the value of elevation to a proper one.
@@ALL4AVIATION i know the QNH knob but when ATC tells me to update my altimeter i can’t figure out where that is so i just end up updating my qnh. Also thanks for the help because i know newbies can be frustrating and annoying. (Show in A320)
@@prestonarmy1 when you set the QNH to the right balue then the altimeter will show rhe so called QNH height. In A320 that means that the altimeter will be corrected and ylu can se the QNH height on the right part of the PFD-primary flight dispay. If you will use the right QNH that means that the altimeter-altitude knstrument will show the right value.
@@ALL4AVIATION oh ok
Sorry, but your explanation and definition of QNE is incorrect. This seems to be a common misconception all over the internet, from some sources that should know better. What you are describing as QNE is the Standard Pressure Setting (SPS or STD). QNE is a different thing altogether. QNE is not a Subscale Setting, it is an altitude reading, more specifically it is the indicated altitude of an aircraft on the ground, at the runway threshold, with 1013 set on the subscale. It is used very rarely, in conditions of exceptionally low pressure where the QNH or QFE is so low it is past the range of the Altimeter Subscale and so is impossible to set.
Hey Chris, thanks for your explanation!
