VNAV Explained | Real 737 Pilot

I still get many questions as to how exactly VNAV works in the 737. In this video I'll give you a detailled explanation on how VNAV works and what the different modes do and when it's appropriate to use them.

Your videos are a great asset to the flightsim community and I would highly recommend that anybody interested in flying the PMDG 737 go watch your videos. It's almost like having your own flight instructor. Your videos have given me a MUCH MUCH better understanding of the 737 -700 and it's systems and have made it an absolute joy to fly. Thank You for the help, cheers!

P.S. I don't subscribe to any YouTube channels, it's just not something I do or care to do but I have subscribed to your channel and that says something as to the quality of your videos. Great job.

Great video as always! In my opinion you are the ultimate flightsim reference for the 737!! Always straight to the point, no bla bla bla… but your microphone quality is a striking contrast to the overall high quality of your videos!! Thanks for the videos they are very helpful!

As an airbus pilot, this is what I needed

[agenttex]

Thank You - I’ll watch this several times to get it all and put to practice…

Another excellent Tutorial, you are the Master, thank you! Coffee will be served :)

Thanks for such great content about VNAV. I've learned a lot from your videos and it's more fun to fly the PMDG 737 with your videos. I've always wondered why the 737 has such a large flap ratio, and in other planes smaller (for instance 747 has ratio 1, 5, 10, 20, 25, 30; a320 has only 4 levels).

Hallo Emanuel, Frage: bei 33:01 descent passing 4500ft to 4000ft selected ALT- da ist ein weißes Rechteck um die 4000ft selected ALT über(!) dem ALT tape/ indication, rechts neben VNAV/PTH. Was bedeutet das? Danke sehr!

These videos are amazing. Seriously dude, you've taught me so much about aviation & flying airliners. Kinda made me wish I'd done my life (career) differently now.

I don’t understand if the speed during the approach phase is managed by the fmc or less, because every time you adjust the flap you also adjust manually the speed. Question is the aircraft slow down according to the fmc? In any case when you catch the G/S in the fmc you now have MCP SPD. So I’m little confused. It seems that the auto Throttle works completely different from A 320 where even if when you disconnect the autopilot the auto throttle still control the speed according to MCDU.

Very helpfull as always. You and Mentour Pilot are good pedagogs!

Hi ! Really really great movie ! Lurn a lot of things, thank you Emanuel, it's perfect !

[yams]

Always appreciate your knowledge (need your brain) and how you explain things, makes it easy to understand

[patches]

Thank you for the lessons! Love your insight and learning more about the 737 😀

But as the FMC changes altitude levels to what is programmed, you do have the get ATC approval to change your FL, correct? I suppose you do this just before you reach the way point?

[GCSon-dupq]

Many thanks!! I have a question. At around 38:14, you hit SPD INTV, but the Pitch mode in FMA is still VNAV PTH instead of changing it to VNAV SPD, so we could know that the FMC is now in Approach mode instead of DES mode. I'm doubtful that the plane is in CRZ mode and even not started the initial descent. How come FMC thinks that it is in Approach mode?? Isn't this a bug in PMDG VNAV software?

[Stucun]

Thank you! Great information as always :)

[Stringbean]

Is there any drop in quality when it comes to its study level features? In other words, apart from its obvious size, is the -600 identical to its bigger brother by PMDG? Just asking because it's so much cheaper.

[Groveish]

If you're flying in North America, do you put inHG to QNH part in DES page?

[georgechadwick]

When I miss my T/D because of vatsim the aircraft decreases speed. What is happening and how do I start a vnav descent after my T/D?

[ReefAndReptileAutomation]

Hey there! Where is the FMC getting the des winds request from? is it that .wx file you must put into the folder or does it get it from weather data?
