Thanks for your videos. Just want you to know that I really appreciate all of the knowledge that share with us to add to our sim experience. Ive gotten a lot of information from your vids, along with a couple other channels, since coming into the hobby this past summer.

[@JoeDFWAviation]

I was having RNAV approach problems until I saw your other video covering LNAV/VNAV for RNAV approaches. Thank you for that, I figured out the RNAV approach now.

[@larsw8776]

I always fly the RNAV approaches in VNAV/LNAV and now I know why. Thank you, again, for your invaluable explanations and how-tos.

[@ironlemon666]

I wish I had this video on hand when I was flying the HS B789 to Kathmandu a couple of days ago. There’s an RNP approach to RW02 there that makes a left-hand swerve around a mountain before the short final and for some stupid reason I was thinking the IAN mode will fly that arc instead of just following the extended centerline like an ILS. I pressed the APP button and almost crashed straight into a mountain 😂 Glad I was able to disconnect the AP in time and somehow follow the approximation of the RNP path manually as it was quite foggy. That was as close to wetting my pants as it gets in a sim 🤣

[@Deyan_B_Travels]

You've just answered a question I had for a long time. Thank you!

[@kamranbidar5529]

thank yo so much for your valuable training stuff sharing with community you are a real gift for us wish you all the best

[@nDrewbeatz]

Great stuff, always appreciating these type of videos as they are so informative. I was wondering if you can do a RNP RWY21R at Tocumen

[@johnboy8846]

Another informatve video, thanks

[@HawkEyes223]

Thank you once again!! :D

[@kevinreed3236]

nice job again!

Thank you, Emi :)

More on an NLS? Thanks for the video!

[@gilles2nice]

Hello, Thanks for your very interesting work. I learned a lot of quirks about the 737. I have a request : Could you do a video on how to utilize the whole radio panel on the 737. What you do when you speak to the cabin crew and what you do when you speak to the pax ? Thousands of thank you Gilles

[@A330Driver]

Thanks Gilles! Does this video help? kzbin.info/www/bejne/lZ_chmaEm5Jge6csi=A6FwxBoySO7y4RjD

[@delalima]

thanks for choosing tegucigalpa , i am from honduras

[@Iron266]

If it were a LOC approach, would you engage VOR/LOC and leave VNAV on? Also, on an unrelated note, what rules of thumb do you follow when deploying flaps and gear? I know it may vary between airlines, but some general guidance on it would be helpful to learn how to make an efficient approach. I have a full 737 MAX cockpit simulator, and your videos help me understand the aircraft tremendously!

[@A330Driver]

Hi, yes, by SOP LOC approaches are flown with VOR/LOC and VNAV. On an unrelated answer, this one should help ;-) kzbin.info/www/bejne/aoWumKGun6eYr6Msi=rArtC81x8azK8FwM

[@AirspotterUK]

Can you creat a video about the ETP, where to find the info and how to programme the FMC please?

[@countryflyboy8255]

Wow looks like you were pretty close to the ground in that last 6 or 7 miles. Is that a real approach into that airport in real life ?

[@beefjezos2713]

Yes, its Tegucigalpa Honduras. However, unless youre using the Navigraph nav database the approach really does not work well as it involves RF legs which the PMDG isn’t able to model correctly.

[@hugolo972]

I noticed the plane was too high for the approach , is it because of inaccurate QNH setting

[@wx_zulu]

I was wondering the same thing. I mean that should've been a go-around, right?

[@global6000]

Can I say that a non precision approach like this one at Tegucigalpa is an RNP AR approach? I see that most often GPS approaches with a turn are RNP AR approaches. Also, on an airbus this is 'easier' as you just put it in the MCDU? Airbus seems to have more clear FMA annunciators as well. What is your look on this?

[@A330Driver]

A procedure is an (AR) procedure when the chart says it is. AR stands for approval required and means the airline needs to get authorization to be allowed to fly the approach. Nothing more and nothing less. I agree on Airbus FMAs being more clear to the pilot.

[@micheljobe8706]

@@A330DriverYes, there is more: crew and aircraft qualification. “RNP (AR) approaches include capabilities that require special aircraft and aircrew authorization similar to category II/III ILS operations.” (taken from the Wikipedia page on RNP for convenience, but can be found on ICAO documents as well)

[@J0rdanIRL]

You have mentioned your dislike for IAN before but I do have one question, does IAN offer any considerable advantages over LNAV/VNAV? I feel like it wouldn’t exist otherwise

[@A330Driver]

The big advantage of IAN is that you can fly a non precision approach with the same SOP as an ILS, thus increasing commonality and making it easier for crews to fly an NPA. However airlines seem to disagree. I only know one airline (a US carrier) who actually has IAN mode on the 737, all others I know don't even have it in first place.

[@markusthl]

​@@A330DriverI think Transavia has it as well on their aircraft.

[@tomstravels520]

I would say as soon as you have locked the G/P you can set missed approach altitude. Not like the LNAV/VNAV where you have to wait incase it levels of

[@micheljobe8706]

Well Emi, you probably know that, if it was for real, you wouldn’t be legal on this one since, unfortunately, PMDG’s 737 is not able yet to fly RF legs, meaning not certified for RNP(AR) approaches. Ok, no large turn on this one for RWY20 so you could pull it with enough terrain clearance, but I wouldn’t have tried the one for 02 where there is a leg going around a 5000’ hill ! 😉

[@A330Driver]

If we're going technical I could say no FS addon is legal to fly RNP AR anyway since none of them has been demonstrated to an authority and has obtained permission to carry out the procedure or has established escape routes in case of loss of RNAV capability throughout such a procedure. With (AR) procedure we just need to take some shortcuts in FS.

[@micheljobe8706]

@@A330DriverOf course… it’s not so much about the legality (we’re simulating after all), than the fact that the LNAV system of PMDG’s 737 draws straight lines in between the RNAV points, and thus brings you outside of the RNP of 0.11 for such approaches, to the point where it could bring you into a CFIT if there was a large turn in between two points. So, my remark about “legality” was more about terrain clearance than legal matters (aircraft is not equipped for that approach)

[@miguiaus9993]

@@micheljobe8706 PMDG has not been able to update their LNAV for more than 8 years now. WT Boeings are far more advanced in that regard. Or the Zibo of course.

[@Pilot-V]

very interesting, never noticed lnav flaws on the pmdg but after reading that you're completely right @@micheljobe8706

[@beefjezos2713]

@@micheljobe8706you are asking him to admit in any capacity that PMDG LNAV is severely limited which he unfortunately is never going to do.
