ATPL Tips - Altimetry 1; QNH, QFE, QNE & Pressure Altitude 

Hi Tom. Not sure you will read this as you don't seem to be around here anymore, but wanted to thank you for sharing your knowledge/methods. Passed my last ATPL exams today (gnav) and you helped a lot. Many Thanks🙏

Extraordinary videos, very well explained, very good sketch's only one recommendation. The QNH calculated by QFE and not vice versa (QFE is the actual measurement of pressure in the airport and QNH is the reference of this pressure to the mean sea level - MSL)

I can not understand why there are 6 thumps down. The explanation is brilliant. The are always wierdos in this world ! A million thumps up

This is not just a thumb up. A well done, great job.

Just excellent. way better than my ground school Instructors. way to go Tom!!

Hi Tom. Thanks for a great vid and excellent explanation. I'm studying for my CPL(H) but your vid just did it for me, out of ALL the info I could find. Keep'em coming, please.

awesome video! thank you for taking the time to put this together

Thank you for this, has helped me out a great deal!

Good explanation. Am beginning to understand the subject matter. Thanks. Very helpful

Hi Tom, your videos are by far the most helpful I've watched, thank you so much I wish you had some filmed course I would definitely pay for it. no brainer. thanks again!

Hey Tom . Thanks a lot for this video . I am preparing for CPL and this video just saved my life! keep producing such videos...thankyou!

Very easy to understand tutorial ...Great job !!!

Hi Tom, you are simply wonderful !! thumbs up buddy !

Thank you so much! Followed.

Awesome explanation Sir. Thank you

Thank you very much, very helpful mate !

Thanks.. This was really helpful.. Very nicely explained.. 👍🏼

Excellent as always Tom

thank you very much mate for this Great and clear explanation

thanks a lot mate... you are doing a good job , keep up

Hi my friend.. excellent work.One extra tip is to do QNH-1013 and not the opposite because when you find negative number it's more easy without drawing to understand that you must subtract.keep going the good work. Greetings from Greece

Your videos are so good, seriously. Please make more :)

Nicely explained and very clear diagrams. I am going to follow through with your other videos on this subject and I HOPE that I will understand when to usre each or which to expect from atc. Nice one.

Heyy there, Leme get straight to the point After watchin ur vid, everything literally became so easier to understand and i think no one can explain any better as u do so im hoping u will still continue to make more videos on navigation and meteorology and other aviation courses....I’d really appreciate it....

This was really helpful!! Thanks a lot!

I have learn it today i think i wont hesitate while doing my presentation👌😊

I have one question?when i studied Atpl the definition of qne was absolutely different.QNE was not pressure setting,it was an altitude.It was used for mountains areas where you can set on your sub scale QNH due to limitations (950-1050 hps if i am not mistaken).So Definition of QNE was ,it is an altitude not Flight level, when you set 1013 hps you see on your altimeter current elevation of aredrome where located in mountains areas where elevation is very high

These videos are all great! Thank you so much for making these, please keep going!

Thankyou soo much man❤️

I think I need to point out that the word "Elev" shouldn't be level with the minus sign or else the result would give an erroneous and ridiculous number. That is, the division sign should be the one with the Elev above it. Just saying.

thanks a lot

THANK YOU A LOTTTTT!!!!

This is more than prefect can you please send me the pdf that you told us about the Skitch of qnh and qne

I’m studying for my théorical drone pilot exam out here in France and so far , I have read in my books that it’s 1hpa=28 feet 😂, I watch videos of different explanations about this and most of them state 1 hpa= 30 feet ...

This is a good and carefully structured aviation teaching video. However, language is powerful and I believe that you forgot one crucial detail that is pedagogically not trivial in my opinion: It is vitally important to remind your listeners bluntly that both QNH and QFE are "altimeter settings" (specifically, pressure numbers we put into the Kolsman window). However, and I think this issue causes much confusion for any beginner, QNE is *NOT* a pressure number we input to the Kolsman window. QNE is an ALTITUDE. It is the altitude indicated on the instrument whenever the Kolsman window has been loaded with a very important but arbitrary value. Thus. . . . .QNE is the **Pressure Altitude** (as you mentioned in passing). If we set 29.92 (inches Hg) in the Kolsman window, the altitude shown by our altimeter is Pressure Altitude no matter where we are flying over Earth and no matter the local weather below on Earth or around us locally. Every pilot here in 'Murika must set 29.92 inches Hg in the Kolsman window before climbing above 17,999 feet MSL.

The way you said altimetery and spontaneously put your hand at the head it showed how much it might have bugged you as its bugging me right now

I have one question. I read in some books, QNE was not standard pressure (1013) but it was the altitude indicated by altimeter with 1013 setting when aircraft is on runway surface.

I need a help to make sure that i understood the concept correctly, please help. Example:- Airport elevation- 5600 feet. QNH- 1023 hPA QNE- 1013.25 hPA PA-? [Reference used -1hPA=30 feet] My Answer:- PA= 5600 + ((1013.25 - 1023)*30) 5600 + ((-9.75)*30) 5600 - 292.5 =5307.5 Since PA is the height from QNE (1013.25hPA) we substract or if follow the math, then plus minus = minus. However, if QNH would be less than QNE, then we would have added the calculated feet into the elevation rather substracting. Am i right?

Here is Q.. qnh is equal to 1013 and ELEV is 0 then we have a rare case of 0 PA.. what does that mean from pilot point of view? thanks and lovely video

Hey - I'm curious how'd you managed to set your calculator so it shows 2 last calculations stacked one after another. It is quite helpful I guess. Mine shows only 1 calculation with whole lot of space free.

What is the QNH and the density altitude?

Morissette Mountain

you left out inches. North America doesn't use hpa

Meaghan Freeway

New syllabus LO state 1hpa = 30ft.

Matha, physics

how we can account QNH ?

hello Tom, how can I contact you?
