🤦 world aint nothing flat let me welcome you into the world of military especially the navy and airforce and its simple the 2 reason why radars are used to guide bombs is to guide bombs to the target 1 and 2 if you launch a bomb from a destroyer sub or aircraft it'll fly straight depending on altitude but not so much as to flying 30k above ground doesn't take much but missles still curve to the earth curveviture meaning the missles go up and down cause its gotta turn with eath curveviture is more noticeable when firing it from a destroyer watch a cruise missile goes up and down cause its compensating with earth curveviture not jus to go up and down shoot a missle straight and watch it fall down without guidance cause its not compensating for eatrh curveviture
Thank you. Echoing what others are saying. This is an excellent tutorial, and has to be one of the best on the subject matter for flight simmers by a country mile. To the point and crystal clear. Well done and thanks again.
@@jonbeckett Totally. Baro, alt., QNH etc etc. It's stuff that I understand now - but had zero idea of 3 years ago. No one really explains is concisely, I think a video like this will help a lot of people plug their own gaps too. I knew of - but didn't really understand - the level. I do now.
Well, what a great video, a nice step by step explanation of areas that weren't quite clear in my old head. It's a pleasant change from other "instructional" videos I've watched (A320) where the presenter is zooming through the video, flicking the switches, not explaining what is doing what, as he's too busy yacking on about his days flying Spitfires for Monarch Airlines 🙄
A mench that US transition altitude [10k ft] and that used is in most other countries [varies] might have been useful. Otherwise, excellent explanation and presentation as always.
Probably a stupid question, but how do airliners stay at a fixed flight level if the temperature changes as they fly large distances? If the local temperature drops as they fly over the ocean would they need to adjust their actual altitude to maintain the same indicated flight level?
Once above the "transition altitude" (which varies), all aircraft tune their altimeter to "Standard" - so they all agree with each other. It is important that they all agree with each other's altitude - not with a specific altitude above the ground.
@@jonbeckettSo if a particular region is warmer than standard, do all the aircraft in that region adjust their altitude so that they maintain their assigned FL? Kind of like the rising tide lifts all ships. They change actual altitude but all change together so they can maintain separation?
@@darmok072 Everybody sets their QNH the same - so if one person thinks they are at 36,000ft and another thinks they are at 35,000ft, they SHOULD be 1,000ft apart. Neither might be exactly that over sea level though.
Hey Jonathan, I’m going to apologise in advance because I’m sure you’ve probably answered this I the video and I’ve missed it but how do you know what to set your QNH to when one the ground in departure airport because I know it’s not always 1013 HPA or 2992 IN?
@@jonbeckett If I understand correctly, I first set the Query Field Elevation at departure, which I find on the map of the airport of departure. During the flight I set the Query Nautical Height to 29.92 inches during the transition altitude. And before landing I set the QFE of the airport upon arrival with the data of this airport. so when planning the flight I need to know all the details of these airports!
Why the control tower keep given you the QNH after you set it in STD AND WHAT INSTRUMENT do you set if the other one is in STD? In an Airbus if possible. Thanks
I don’t feel like watching a 15 minute video for this, stupid A320 telling me to descend FL 350 and I at FL350 I’m sick of AtC yelling to decent to correct flight level
Before anybody mentions it - when I said "the earth isn't really a sphere", I meant that it's slightly flattened - NOT flat :) lol
I used to think that as well until Pythagoras put me right. 😅😂
Way too funny, i even thought it was flat, and 5G was the cause of Covid, you live & learn 🙂
It's an Oblate Spheroid.... if I recall my school geography days.
Good save cuz the world ain’t flat

Explained better then anyone else online.10/10
Well done on being pretty much the first one to do a video on this since MSFS.
Really? I'm just plugging gaps in my own knowledge along the way, and thinking "I wonder if anybody else is interested in this?"

You made that easy to understand. Thank you!
Amazing guide, easy to understand, props to you mate !!
Big thanks for this, very useful 🙂
Very good explanation
Cheers :)

You're welcome.
Thank u my mentor ❤❤
Excellent stuff, cheers JB.

US transition altitude is 18,000ft.
@@jonbeckett That's inflation for you!
Great explanation and nice clear slides to demonstrate what you're saying!
Glad it was helpful!

Press B. It shortcuts it to the local QNH.
@@jonbeckett In X plane you cannot press B, these are the brakes!
where can you find the right information to set your QNH?
@@pfv3462 You might have to adjust it by hand in X-Plane :)
