This is ABSOLUTE Gold Right here. Anyone confused regarding this topic must watch this video. Properly explained for new training Pilots. Thanks a lot. I wish more success to this channel.
Difficult subject with exceptional clarity! Thanks so much! It’s one of the few areas I missed on the practical test because it is so complicated, and few ground instructors, or CFIs can explain this clearly, without time to prepare.
Aviation theory has always been my favorite channel for making things clear as day. Hope you’ll keep making videos like this which will cover everything, i mean EVERYTHING, we need to know while preparing for ATPL
Thank you so much for putting all of these concepts into practical sense for me! My brain does not process things in just plain language and when you explained things in how it's practical and their relation to other concepts, it makes so much more sense. Really appreciate it!
Thank you so much! I’ve watched other TH-cam videos about QNH, QFE and QNE altimeters but didn’t really understand them. But your video was very easy to understand 👩🏻✈️👍🏼
While flying in MSFS at night, I didn't properly adjust the altimeter, and when I descended to 2000 feet to prepare for landing, I was actually just 5 feet above the ground.
Hi hope you are good. I have a big list of interesting question for you pilot. Answer as much as you wish… 1. Who gives us trans level when it varies (atc , atis ,any others) 2. Trans alt is fixed for countries . How do they calculate it ? 3. What is the maximum thickness of transition layer. (the answer should highlight the importance of having the layer and not only 1 level reference but a layer...) 4.What are Common trans alt for some countries 5. Transition layer only climb and descent we never cruise there.Its not common for atc to say maintain FL or atltitude inside transition layer ( but if they ask maintain we should maintain... )but my question is that they ususally dont cruise there true... since we wanna climb and descend . And if controller said maintain a flight level or altitude in between the layer… it would be risk if no horizontal separation of aircraft also it would be risk if airclafy arf flying or descending around it true… 6.Why don’t all countries have the same transition altitude. 7. Is there a benefit of decreasing this transition altitude .I mean in Lebanon transition altitude is 13,000 ft while in germny transition altitude is around 5,000 ft. 8.Can we have sps standard pressure system 1013 hpa =qne at local conditions = qnh is it possible? 9.Whats if passing throght a surface inversion ? wouldn’t local presuure change.. would atc know or atis know if a surface inversion suddenly happened... 10.How many times do we usually change qnh : local pressure while climbing? While descending? 11.Who uses qfe the field of the pressure ? Russia? Airshows close close to the ground or even sometimes airlines to cross check things? 12.How is transition altitude determined? ( also note that Denali Mountain in USA is higher than trasn alt 18,000ft) (hmm i though trans alt should be clear of all obstacles) 13.What about the horizontal and vertical separation in transition layer? How is this done? Do different countries have different regulations and procedures for this? 14.What if it’s a busy airport like London heathrew airport and trans alt is low maybe I belive it's 3,000 ft . 15.1013.25 or 1013? Doesn’t it make a difference? Cant this rounding cause errors or accidents? 16.What is the relation between 1hpa = 27 ft around 9m …Is this number always constant ... shouldn't it vary with temperature or pressure? 17.If its foggy isn’t qfe field pressure better than qnh local pressure … also can you land if its extremely foggy and cant see anything? 18.There is an instrument in cockpit called radio altimeter (I n cat 2 or 3 ils) that works below 2,500 ft maybe that reads height (above that its doenst show )....it shows only in cat 2 or 3 but does it need the pressure as well? 19.What are rounded to 1000 ft and what are rounded to 500 ft ( trans alt and trans level) 20.How do you find qnh if you don’t have a control tower or traffic? 21.Do some counties have a fixed transition level ? 21.What if a country has many airports? Do they all have the same trans alt? same trans level ? hmm? 22.While descending some pilots put qnh long before reaching transition level ? hmm ?why? isn't this risk? Or im mistaken they apply qnh at
Very good explanations. Wasn't keen about the digital voice - but ok. Also, another way of phrasing decreasing temps is "From hot to cold, don't be bold." Thank you.
When tow aircrafts are moving to opposite direction and they must use same barometric pressure to maintain the adequate separation. Example, Either QNE or QNH, but ny question is how the different aircraft will know who is is using which one QBE or different one.
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?
Hi! the problem is that QNH is constantly changing for a certain area, so for aircraft flying at higher levels it is better to use a standard setting (QNE) to ensure all aircraft are separated properly independently of the true altitude above sea level.
@@AviationTheory oh! That means the mean sea level for different parts of the world is different? Didn't know that. Why can't we use qne for both high and low altitude then?
@@phoonjzc watch the video again, from12 minutes. If you use QNE near mountains there will be risk of crashing into the mountain. hence at lower levels (Transition Altitude) we need to use QNH
@11:04 how come 7650 ft !! can someone explain please? as per my calculations if mercury is is reduced by 2 inch for every 1000 ft, then it should be 7k+390 = 7390 not 7650! what am i doing wrong?please help

I'm an airline pilot from India. Thank you so much for explaining in such detail and depth. God bless you and good wishes in life ahead.
Difficult subject with exceptional clarity! Thanks so much! It’s one of the few areas I missed on the practical test because it is so complicated, and few ground instructors, or CFIs can explain this clearly, without time to prepare.
Wonderfully explained. This video explained the concept in 20 mins which couldn’t be explained in a 2 hour class.
As a PC flight simmer, I learnt a lot watching this superb presentation.
Thank you !

Was able to watch this without sound and still get it. Very good video.
Thank you so much! I’ve watched other TH-cam videos about QNH, QFE and QNE altimeters but didn’t really understand them. But your video was very easy to understand 👩🏻✈️👍🏼
Best video on that subject on TH-cam! Your videos are great, clear, super structured and very tangible, keep going and thanks a lot!
Thank you so much, I've spent the last few days trying to understand some of these concepts and this is just what I needed to get it to stick.
I would like to say "thank you so much" about your useful video. It's easy understanding and comprehensive!👍
Please make more helpful presentation!🥰
I only fly on the PC, but I want to have a realistic feel for flying.
I am very grateful for that excellent explanation. Many greetings from Austria

Excellent!
Hi it's fantastic explanation
Thank you very much.
Need more videos like this 😢
Excellent concise explanation. Better be careful where you want to use the units 'klopp skulls' though.
Thanks
Amazing content. Subscribed.
Thank you so much for this priceless information i’m very grateful
Thanks I am about to start my ppl ground lessons
Quite helpful!
Amazing. Finally
thank you
Thank you very much
Thanks for this video
I have to say thanks a lot.
thank you somuch
God bless you
Very nice 😍🙏✈️
Very good!
those videos are excellent !!
Please share some questions related to altimeter
Very good explanations. Wasn't keen about the digital voice - but ok. Also, another way of phrasing decreasing temps is "From hot to cold, don't be bold." Thank you.
Hi May I ask you what subject or books I need to study and become commercial pilot with my appreciation.
Helpful video 👍
Mnemonics Qfe=field elevation, Qnh=nautical here, Qne=nautical everywhere
The problem with having a computer read a script is that sometimes the pronunciations are pretty weird. For instance: HEC-to-pas-CAL.
When tow aircrafts are moving to opposite direction and they must use same barometric pressure to maintain the adequate separation. Example, Either QNE or QNH, but ny question is how the different aircraft will know who is is using which one QBE or different one.
Very important
Supreme 😍
so an aviation altimeter should work fine in a deep mineshaft below sea level then right?
In theory yes! The indicated altitude would be negative in that case.
Any entire series for ppl or cpl?
Vert informative
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?
Can someone please explain how two differents settings shows same altitude on the altimeter?
Does GPS help to avoid these kinds of errors?
1013 hPa is slightly inaccurate. Actually, it is 1013.25 hPa which pilots set, when they press "STD" on the barometric altimeter.
❤❤❤
How do we depart from Airport A to Airport B and how to change from QNE to QNH in an indicator. Best Regards
Air pressure decreases with altitude more rapidly in cold air compared to warm air. is this true or false?
True!
Why do we need to use QNE to measure flight level? Why are we interested in a virtual point? Shouldnt we be interested in the ocean floor instead?
Hi! the problem is that QNH is constantly changing for a certain area, so for aircraft flying at higher levels it is better to use a standard setting (QNE) to ensure all aircraft are separated properly independently of the true altitude above sea level.
@@AviationTheory oh! That means the mean sea level for different parts of the world is different? Didn't know that.
Why can't we use qne for both high and low altitude then?
Why not use QNE for everywhere as a standard since the mean sea level varies across different place? please explain in simple terms. Thanks
@@phoonjzc not the sea level, but the pressure at sea level changes constantly through temperature changes
@@phoonjzc watch the video again, from12 minutes. If you use QNE near mountains there will be risk of crashing into the mountain. hence at lower levels (Transition Altitude) we need to use QNH
Why terrain heights are not based on msl so we could use QNE

sorry , but at 4:16 is qne not incorect??
yes ok I got it we are going up as we go down..
