QNH, QFE and QNE - [Altitude, Height and Flight Levels explained]

The QNH and the QFE are pressure references, the QNE gives you the feet difference between your aircraft and the standard 1013hpa pressure reference.
The QNH is the pressure at the mean sea level expressed in Hpa, this pressure changes from place to place depending on the weather.
As you know with the night and day the level of the sea changes, and when talking about the QNH an average sea level between night and day has been used.
If you use the Mean Sea Level as your Altimeter pressure reference you will fly following Alitutdes.
It is important to use the QNH during the departure because you want to be separated from the obstacles and since the terrain uses the mean sea level as a reference you want to use the same reference, otherwise, the separation won't be possible.
The QFE is the pressure at your Airfield, an easy way to remember this is to take the F of QFE and associate it with the F of the Field, in this way you will never forget what the QFE is.
If you set the Pressure at your Airport as a reference you will fly following heights.
The QNE uses the Standard pressure reference of 1013,25 hpa which is used after passing the Transition Altitude.
If you use the 1013,25hpa as a Pressure reference you will fly following the Flight Levels.
Even if we commonly refer to QNE as a pressure reference if you really dive in deep you will find out that is not a pressure reference.
Watch the RUclips video below to get the full QNE detailed definition:
• QNE Is Not A Pressure ...
If you want to know more about the Transition Altitude watch the videos below:
• Altimeter Setting - [T...
• QNH and QNE Altimeter ...
As you can see an Aircraft flying at a constant level can fly using different pressure references.

Any question regarding QNH, QFE or QNE? Leave a comment below and I will help you out!

[@vantranthi398]

I knew that in some book they called QNE being pressure alttitude of an aircraft when it is on runway, so QNE is not a pressure value. 1013hPa ia standard pressure. Is it right?

[@PILOTCLIMB]

@@vantranthi398 This is true on a standard Atmosphere condition however, in real life the QNH varies thus, with a QNH of 1000hpa, at your airport, for example, the QNE is not your elevation anymore. Yes, many times we refer to QNE as the pressure reference however, if you look at its very correct definition is the difference expressed in feed between the 1013.25hpa and the aircraft.

[@vantranthi398]

@@PILOTCLIMB thank you very much for your reply. I have more questions
1) As you told “ QNE is the distance btw 1013hPa and aircraft”. We all know “distance btw aircraft and 1013hPa is Pressure altitude”. So why in some books people need to use QNE as pressure altitude?
2) 1013hPa is standard pressure, why in some book people need to use QNE as standard pressure.
Should we confuse pilots by those 2 things?
3) In our area we follow ICAO and WMO terms. Would you tell me in which doc/book I may have QNE definition?
Thank you in advance

What is meant FL 380 in aviation?

[@PILOTCLIMB]

@@doonaviation5864 Hey, Thanks for watching!! FL380 equals 38000 feet from the Standard Pressure Reference of 1013.25Hpa.

[@ClanLawrence]

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.

[@PILOTCLIMB]

Thanks for your feedback! I made a separate video about the topic you commented!

[@ClanLawrence]

@@PILOTCLIMB Yes. Your definition of QNE is incorrect in that video too.

[@benokohministries]

If you’re some where at 3,000 ft on final approach, and the QNH is 10.20 Hp, and field elevation is 433 ft, how then do you calculate how many feet to land? From the altimeter should you aim to torch down at 433 ft being the field elevation? I have tried aiming to land at 433 ft from the altimeter, but it doesn’t work. I would finally torch down at 344. Pls how do I calculate it right?

[@PILOTCLIMB]

Make sure that the QNH is correct, also check the Threshold elevation that sometimes is different than the airport elevation.

[@hajeralthehli86]

Hello Captain, could you please explain to me how the aircraft get separated since all planes maintain the same standard setting 1013 hPs during the cruise phase. Thanks

[@PILOTCLIMB]

Since they use the same pressure reference if they fly at different Flight Level they are separated. Check my videos regarding altimeter settings..

[@muhammadfahamfaisal5880]

[@martin81bayern]

Thanks for the explanation.
But in theory it would still be possible to do all the vertical seperation and flight level stuff based on QNH instead of QNE and considering that there is a bottom layer of terrain which cannot be used for aircraft separation.
QNE seems to be a helper for the "terrain problem" only. Nothing more and nothing less.
Many of abbreviations for relatively simple things... the aviation business really loves complex sounding abbreviations :D
Greetings from south Germany

[@atifnuman3354]

Why don't we use QNE always instead of changing from QNH at transition altitude

[@atifnuman3354]

We can also get altitude of terrain in QNE reference

[@PILOTCLIMB]

The EARTH is obviously not a ball when a plane can fly at a set altitude for miles and miles and miles because of how all elements find their LEVEL.!!!! There is NO Coriolis effect affecting a plane's flight.!!!!! DUH.!!!!!!

When you say that the mean sea levels changes depending on the water, and when the Mountain takes as reference the QNH, should have also not change the Information regarding the height of the mountain on the charts all the time ? I this case there must be a safety separation to the height published on the charts of the terrain, which enusures Terrain separation even when the QNH changes are big ?

Hi, I would like to ask you something if you don´t mind, just an observation, when I was studying, long time ago, QNH was the pressure at the MSL, but calculated from the pressure at the airport and then reducing as per standard 1" ----1000ft in this way calculated the QNH. Is this still the way I supposed or not?. Thanks in advance

[@PILOTCLIMB]

Hey, many thanks for watching, and welcome on board!!
Yes, as far as I'm aware, the QNH is still calculated starting from the pressure and the elevation of the airfield.
Once you know the Airfield Pressure (QFE) and Elevation you can find what is the local QNH by applying the standard pressure variation of 30feet per Hpa.
The temperature that is used to calculate the QNH from the QFE is the ISA.
Don't hesitate to ask questions when watching the rest of the videos!
I wish you a great weekend!👍
