METEOROLOGY | Altimetry (QFE, QNH, QNE) 

New lapel mic has just arrived so audio quality will be better for videos recorded from now on (hopefully). Thanks to those who gave that advice. -- Previous Lesson Video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XAs5Bkob4n4.html

Q nh =. Nautical Height Q fe = Fieid Elevation Q ne = Nautical Estimate or En Route FYI 👍

I always remembered them as FE = Field Elevation, NH = Nautical Height,, NE = Normalised Everywhere. If that helps anyone else remember them, you're welcome. After that and 27ft/hPa, it is just arithmetic and correct visualisation of the isobars in relation to each other. I'm lucky in that respect, as the product of a Chartered Civil Engineer and a Mathematics Teacher! Also, when looking at a low-level chart, raised obstructions have the altitude marked first, then the height in brackets. The first figure is what your altimeter will be reading if you hit the top of the obstruction, the second is the distance you will fall afterwards.

You're such a blessing ! You're one of my most fav RU-vid channels out there and I really appreciate all the time you take to make these videos. Ik it's old but feel like stumbled on gold haha

Greeting from Japan ! I watch Japanese RU-vidr who focuses on ATC, so your movie helps me to understand in multiple language :)

Thanks for the video. Great job!

Thank you for doing this. I think I understood altimeters a lot better than from other explanations I've seen now. Good job! :)

thanks for the vid, hope you have a nice day ;)

This made sense! Thank you for posting!

Funny, I had been wondering how altitude was really determined given the differences in terrain. Not a pilot but raised by one, so I think about this kind of stuff!!! XD

Well done - thank you.

Very well done! I’m a student pilot and I’m gonna take the theory exams in a few months, so every bit of practice i get is useful. Thanks mate 👍

Great video, thank you. 👍

This is the best explanation about this topic I ever saw. Thank you!

Thanks mate ! Great content.

Very informative, thank you:)

Keep it up please!!

Very well explained. Thank you.

Yes. I need it. Thx!!

This is massively helpful. Thank you.

excelent video, thank you very much

Great vedio, thank you sir for that

My only complaint is the lighting on the board. Other than that. Great content as usual!

Math problem at 17:57, plane is set to 1013.2 qnh, but the plane lands somewhere where its 1023 qnh. The messed up altimeter setting is now 270 feet off (negative). Airport is at 290, so the (now incorrect) altimeter will say 20. It took me like an hour to wrap my head around it.

Great information! Very interesting... Thank you for this video, keep it up...

Q code’s are still used in Amateur radio, mostly CW. I would like to know about the WW2 “R” codes that were used in the UK by the Bomber squadrons.

Maaan.. better than aviation school, keep posting more instructional :)

Sir. Its very. Simple explanation Really useful Thank you so much Iam from India. Iam a cpl trainee

Very good explanation! This subject is hard to understand for many people.

ahhhh so thankful i passed my atpl exams and dont have to worry about calculating them and practising them everyday xd

I'm confused from which altitude i have to calculate the temperature correction error. can you please help me

You like many, many other sources are explaining it as if QNE was only used above the transitiion altitude which isn't strictly true. QNE can be useful when the airpressure is outside the value that can be set on the subscale of the altimetere. I've also seen it being used in the handout for pilots of a gliding competition - not sure why, the weather there certainly wasn't extreme, I was wondering there are altimeters that can' tbe adjusted at all? Or the button has fallen off ;-) Various sources alternate between describing QNE as the standard pressure of 1013.25hPa or the altitude indicated when the altimeter is set to that standard pressure of 1013.25hPa. This is what Skybrary says: "QNE is different to the other altimetry Q codes in that it is an altitude not a pressure (although it is commonly incorrectly described as such)." I take Skybrary is as close to authoritative as it gets, so this is how I'm using the term QNE.

Good. Just a question. Is the formula QNH=QFE+Alt(feets)/28.5 Correct?

Please, buy a better mic. Otherwise thanks for the video, your explanations are amazing

Do you have Aeroméxico AM549 aborted take off comms?

Thanks, long duration but actually.. simple 👍 For the last question, i just subtract 1.023-1.013 = 10 hPa because i still remember that the last 2 digits behind the decimal are the significant figures rules in physics. Can i use that ?

Could you go over the proper steps to clear a power surge in the engine/engines?

Thanks. We mixing metric with Imperial? We missed Mars doing that...

Saw your handle in some of the avexam comments 😂

Dear VAS, some of my comments are missing from another of your video comment section. Do you ever delete comments? If so, did you delete mine? There was no objectionable language or ethnic content in them. I am curious.

where is p2?

Can you please do a gnav lesson on quj,qte,...

how did i get here so early lol

What if we are on sea level and set QFE while the airfield is actually above us?

But when is QFE used instead of QNH? I just don't get it imma bang my head into the damn wall

Hi from Iraq 🇮🇶

Saw a line of toilet seats on my feed before i saw it was VASAaviation and i was like.. oops. Those were planes.

Wonderful video, where are you from ?

Plz, get a better mic.
