Finally someone explained it. How the hell is Boldmethod the only place where you can find actual explanations on all of these things...

Aleks, thank you so much for devoting so much time and sharing your knowledge of aviation on these live sessions. I always tell everyone that you were my II instructor because the one I was assigned was mentally checked out, ready to move on to the airlines, and only doing it to pad his pass rate for a Gold Seal. These webinars were crucial to my development as a pilot and II. Thanks to you and the Boldmethod team, I was able to develop and teach high quality lessons to my students that they all thoroughly enjoyed. All 8 of them passed their instrument rides the first time and thanked me for my efforts to help them understand the complex environment that is instrument flying. Your readily available service has greatly enhanced the overall safety of the National Airspace System and I would even be so bold to claim saved lives. I hope you are recognized for your service to aviation and know how greatly appreciated it is by the whole community.

As an instrument approach procedure designer at the FAA, I found this video to be very informative.

Dear FAA, why can't we have a worldwide standard based on ICAO?

Honda HR-V The Crossover that gets it right That’s way above my level. I know we’re adopting more ICAO standards a little at a time. I imagine it has to do with the amount of work that would be required but I really can’t say for sure.

@Johnathan Celso I came to the United States as a child in 1973.. When I get in class the teacher tells us that we are moving to a metric system and that soon, all the speed limits are in kilometers... almost 50 years later I am still waiting...

As the God Himself, I find you and other idiots who say they were the father\son\coworker of someone mentioned in a YT video so annoying...

There is so much in here that I have never seen laid out like this before. This video is absolute GOLDEN for any IR student.

best explanation on RNAV approaches I have ever heard!!!! Great job mate

This video is simply the best I've seen about RNAV. I'm a Brazilian Air traffic controller and I work on a ACC. This is amazing and now I understand the difference between the procedures. Thank you very much!

I'm a pilot in IFR training. This was the best rundown on this stuff I've seen and I've used many different products. You guys are great, and I've got several of your courses. Bravo!

I’m loving these live streams. Seriously, you guys are brilliant! Thank you for being so generous with your time and knowledge.

The technical quality is absolutely superb, and the introduction is simply outstanding!

Excellent explanations and videos! I'm a 50 year pilot and new CFI working on CFII now so I plan to have my instrument students view this very clear explanation of the various flavors of GPS approaches. THANK YOU for sharing these with the community.

Currently I am working on my IR/ME here in Europe. During my PBN lesson , at the end our instructor said: "listen guys if you feel lost in the topic I will show you an awesome video". Guess what. He showed exactly that content. It speaks for itself. Thank you theboldmethod

Great videos! One suggestion - maybe about every tenth time you mention an acronym, you might use its expanded name, just to help us embed them in our minds. You guys do a great job - and we benefit from you being based in a mountainous environment so you are more attuned to the challenges of tricky approaches vs those of us in other parts of the country.

The absolute best description of ‘GPS RNAV’ system I ever received! Flight Safety and other ‘professionals’ school instructors that I crossed path don’t hold a candle to this informative quality!

I’m an IFR student and this video was ridiculously informative. Wow! So helpful. I know this was a few years ago, but thank you!

The best instructional videos I ever watched . The explanations are very clear ! Congratulations

First video I had to watch 3xs. There’s so much info 🙌🙌🙌

Me too!

The greatest explanation ever. It's usually hard to find such detailed videos regarding Approaches(or other aviation topics) on youtube. In general, what we could find is people talking about what's in the books and not what's going on in the real world. Your practical examples are amazing and I could relate it with what I am working on as a Flight Management Systems Engineer. Just a small suggestion - the title of the video says "The Difference Between LPV and LNAV/VNAV Approaches" however, you have gone beyond just explaining the difference between the two and have covered a wider aspect of approaches, which is great. Consider changing the title to something more generic so that the video gets hit more with generic key words.

This is probably the most detailed RNAV/RNP video on youtube.

Hi from Belgium! Great material! Just for your information, in European airspace, all RNAV (GNSS) procedures are beeing renamed into RNP starting May first 2019 in compliance with ICAO naming standards. By end of 2020, there should only be 3 types of headers left: RNAV (old type tech like vor rnav w/o performance and alerting capability), RNP (typically replacing RNAV(GNSS) current title), and finally RNP(AR) if authorisarion required. The FAA will not change the naming convention for the time beeing and will stick to the current denominations.

Arno Fontana Great info for me as Portuguese student pilot thank you.

Best explanation I have ever heard of these various modalities for IFR approaches. Thank you. Great work!!

nice job, only person I found who knows what they are talking about and how to explain it

Hands down the most informative presentation on these topics I've ever seen. Thank you!

Really appreciate the detail that you guys went into to explain the various RNP and scaling differences between LPV and LNAV/VNAV. I had been fumbling though the aim for weeks searching for an answer but couldn't find one till now.

One of the best instructors that i have ever come across!!!.Thanks for the video.Definitely it gave a clear picture to me regarding the RNAV approaches.

Best explanation of approach types ever. Very concise and very understandeable!

I wish I had watched this several months ago! Great information and you cleared up a lot of my questions that Jeppesen didn’t cover. Thanks!

This is so good! Too bad I missed it live. I've gained a hole new level of respect for this channel.

I was looking for a quick explanation, but I really got a nice education. I wish I saw this before my instrument check ride.

This is the best tutorial one can get about RNAV. Thanks a million.

Wow... After the seeing this video, I became the most knowledgeable pilot instructor in my company regarding RNP/Rnanv ..... Thanks a lot....

Thanks for a brilliant explanation to the differences. You have taken a seemingly difficult topic and broken it down into simple compartments. Really learnt a lot!! Keep going.

This was a great presentation. Love the way you integrate the questions and answer them as they come up. I learned a lot! Currently working on my INRAT and this answered a lot of things that you can’t assimilate in a heavy task environment while flying an approach. Thanks!

Love these videos! Absolutely the best on KZread. Can you please make a video on raim, waas, and explaining how gps works.

Top notch. I will watch again as it was so useful for experience pilots like me who is transitioning from round dials and pointers; ADF, ILS, LOC,VOR , DME to the Garman 1000nxi glass cockpit and a FADEC system aircraft. Looking forward to a great learning experience.Thank you for your time and energy.

Just a little note. When talking about level of service we can actually chose between LPV, LNAV/VNAV or LNAV in our FMS by selecting LOS (level of service). We have to do this on a regular basis as our company is not approved for LPV appr.

Excellent overview of the RNAV approach and GPS capabilities and procedures. I will be getting back into IFR flying after many years away and this has been very helpful in getting me back up to speed on the latest tech improvements to IFR flying. I hope to see more videos in the future on all aspects of the IFR system. Thanks again.

I am starting my IR very soon and this content is just awesome....it pulls all things together. Thank you TheBoldmethod

Best ice videos online!love the quality and the detailed explanations! Keep it up!thanks!

Just a big thank you, for clearing up all the new changes to WAAS GPS approaches. I learned a lot. I’m very grateful for this video, and think it was excellent. John MacD

Pleaseeee continue with the live streams! You guys are amazing, much much appreciated

Hey, I know comments can fall by the wayside, and therefore i hope someone reads this... PHENOMENAL methods of conveying information. I learned SO MUCH. Absolutely incredible teaching. Ill be binge-ing all things Boldmethod.

It's been said before but I'll say it again -- OUTSTANDING video. Huge thanks for all the nit-picky details.

As usual, excellent presentation. Your wide-range of knowledge of the system is remarkable. Thank you for what you do for aviation!

Thanks for sharing your "big brain," good block of instruction! I may be 'late to the table,' but better late than never. Great video sharing changes in LNAV for a guy that started flying back when ADF and VOR ran the approaches.

Great video. Very informative and taught so anyone can understand the information presented. I’m getting back into IFR flying after 20 years. A lot has changed and this video helped explain much. Thanks.

The presentation was really good, thanks for shearing the knowledge with us!!!!

Thanks from an old cfii. Your making me want to fly again. Yea I was a cfii in the 90’s and this is like a whole new language. But it’s fun to learn about.

Very much appreciate the videos. Yes it's fun to ride along with others but it also very good to go back to class and spend time in learning as well.

Amazing presentation guys! You are doing a great service to the Aviation community by sharing this wealth of Knowledge. Thank you very much for your Time & Effort. Looking forward to many such videos.

VERY informative! I've 'saved' this as 're-viewable favorite'; as I expect to use this and other 'Bold Method' videos as a 'sustainment training' resources. Excellent job!.. BTW, on another 'note'.. As a life long surveyor, I believe that your explanation of: 'somewhere in that circle'; when one has experienced loss of 'WAAS" and has been notified of downgraded navigation, this is then called, or the equivalent of: 'circle error probable' or 'CEP'... and should still meet acceptable standards (with a minimum of 5 satellites) to be considered 'safe' and useful for navigation.

Thank you so much! Totally agree with the others, BEST explanation of RNAV I have ever heard. Don’t laugh I am not a pilot, but a new flight simmer, and could not find a better explanation than yours, I am walking away with a solid foundational understanding. SUBSCRIBED & LIKED & COMMENTED checked!

Great video. As a side note, on the proline fusion system, you are able to manually deselect WAAS and select RNP Baro.

Thanks . this presentation was very informative . looking forward to watch more videos from you guys . Bass

This was great! Being an ifr student, understanding the differences was not real clear until now... Thank You!

Thanks for the great contents always! I believe that one of the approach capabilities at 27:20, the second one, has to be GPS + Baro Vnav instead of Baro-aiding.

This was a very great video that explained a lot about my misconceptions about RNAV! Even though this video is tailored for the airspace in the United States, I still understood it, coming from someone who took training in the Philippines. That being said, I'd like to contribute a little bit to this topic and offer my two cents after watching the replay of this livestream. There were two interesting questions in the chat that were left generally unanswered (but was partly answered in the chat) that interested me: 1) Are there approaches where LNAV/VNAV is listed but LPV is not included? 2) What is RNAV (GNSS)? So I looked around and researched a bit, and looked at the Jepp charts for 3 different countries (one airport each) in Southeast Asia: Japan, Philippines, and Singapore, and what I found out was this... 1) Yes, there are approaches where LNAV/VNAV is listed, without LPV... outside North America (A lot in Mexico, actually, strangely there is WAAS coverage there if I understand it correctly. Correct me if I'm wrong. I also checked the charts for a couple of Canadian airports, which have LPV.) Since the three aforementioned Asian countries are not covered by WAAS (since it's an FAA, North American thing), either they aren't covered by any SBAS (for Philippines and Singapore), or no LPV minimums exist pending development (Japan). Japan has their version of the WAAS, called MSAS. However, it currently offers horizontal guidance only, with LPV in Japan to be implemented in 2023. So until then, A/C flying in Japan will have to make do with LNAV/VNAV. 2) As answered in the chat by Boldmethod, "GNSS stands for Global Satellite Navigation System. It's an umbrella term for GPS, GLONASS, or any other satellite system" So then I had my own question... "But what does this mean in the Jepp chart, really?" After comparing four countries' Jepp charts (I included Canada this time), the answer (probably) is, it depends on the local regulations, the airport, or the approach itself. Japan: [RJSK RNAV (GNSS) Z RWY 10] GNSS Required, RNP0.30 Required (Note how the chart is titled "GNSS" and not "RNP", and that RNP0.30 is listed) [RJSK RNAV (RNP) RWY 28] GNSS and RF Required, SPECIAL AUTHORIZATION REQUIRED, but RNP0.30 listed at Minimums table (Note: It's titled "RNP", so now it has to have the "Special Authorization Required" note) [RJSS RNAV (GNSS) Z RWY 09] GNSS Required (RNP is not listed) Singapore: [WSSS RNAV (GNSS) RWY 20R] (No special notes, just Baro-VNAV not authorized below...) *Did not see any "RNP" titled charts Philippines: [RPLL RNAV (GNSS) RWY 06] (No special notes, just Baro-VNAV not authorized below...) [RPVK RNAV (GNSS) X RWY 05] (RNP 1 required) *Did not see any "RNP" titled charts Canada: [CYVR RNAV (RNP) Y RWY 08L] ("Authorization Required") [CYVR RNAV (GNSS) Z RWY 08L] (No special notes, RNP is not listed) So, outside the USA, I will guess that "GNSS" titled Jepp charts differ depending on which airport/country/approach you're in. :) My two cents. Loving your streams, guys. Can't wait for the Instrument!

Just ran across this recently. 11/14/2021. Very helpful explanation of confusing subject and confusing terminology. Thank You

Just want to say that you guys have great videos. Current 747 Captain and if anyone needs to brush up on stuff, it’s me. Every student pilot or whatever should be subscribed to your channel.

This was an incredibly informative video, it puts a lot of information I had to research and put together on my own in one place. I’m saving it as a reference.

Fantastic video...This is going to become a required viewing for my instrument students. Thanks guys!!

Your guy's videos are awesome. They have helped me so much with my CFII

very, very good. William Duhame says it best. I have never seen all this information in one place. Thank you.

This is so pro. Please keep it up. I fly a HondaJet and I am finding your videos a go to source. Thank you. Don

So glad I found this. Many questions answered. Thanks.

I learned very much watching this presentation. This will really help me as I go fourth with my IFR tng.

Excellent video. Thank you!

An excellent presentation, especially considering the complexity of the subject. As the Operations Manager for our flying club, I will be forwarding this link to all members. Thanks. Mike Laurenzano

Outstanding presentation regarding RNAV/RNP navigation. Thank you.

Amazing better than any course I ever studied on these topics

I doing my CPL.MEP.IR at the moment and this was a BIG help thank you

Very good information. Very well structured. Thank you for taking out the time and doing this

This class is SO good. Thanks!

Absolutely fantastic job done! Thank you!

First of all I want to congratulate you with the very nice presentation. I am from Belgium Europe and I enjoyed the presentation very much. I would like to ask you the following question. On your slide which is titled “Navigation Accuracy By Flight Phase” we can see the different navigation specifications. For the navigation specification “RNP APCH” we can see the navigation accuracy RNP1 for the initial segment and the intermediate segment and the navigation accuracy RNP0.3 for the final segment. I understand that RNP1 means that we have to have a 1 NM accuracy in 95% of the time and RNP0.3 means that we have to have a 0.3 NM accuracy in 95% of the time. For the navigation specification “RNP AR APCH” we can see that the navigation accuracy even goes down to RNP0.1. Somewhere on the internet I read that RNP approaches with RNP values down to 0.1 allow aircraft to follow precise three-dimensional curved flight paths through congested airspace, around noise sensitive areas, or through difficult terrain. Now I have the following question: an RNP system which fulfils the RNP0.1 requirement will garantee that we are within 0.1 NM of our planned flightpath. Does this mean that we fly within a circle with a radius of 0.1 NM perpendicular to our planned flightplan or do we have to see that 0.1 NM accuracy only laterally to our planned flightpath? Kind regards, Johan.

Such a handful of information that u provide. Huge thanks !!

9 haters I hate haters This guy is doing great work thanks a lot 🙌🙌

Excellent video! You are bright and I learned a lot!

Insane level of knowledge on this topic

Thank you for your video.I do fly Phenom300 in France G1000/G3000 and this was a really good refresh!!! Fly safe ;)

I learned so much from this video, it's ridiculous. Thank you!

Thanks Alex and Colin that is absolutely fantastic as usual 👍🏻👍🏻👍🏻

Excellent, thank you!

wooow! a FANTASTIC job! huge thanks!

These videos are super helpful. Thanks so much!

Gosh, I wish this guy could be my instructor. He really explains things well...

Excellent explanation. It will be nice if you upload videos about PBN concept and how VNAV is executed by the systems.

So plain , so great, so clear ! !

Awesome training thank you so much

Thanks! Great job.......AGAIN!

lots of questions answered thanks

Outstanding Work

superb content. the best on the net. expertise that professional pilots pay good money to learn

Awesome, of great help in understanding RNP approaches

some of the best IFR videos on yotube, for real! :D *thank you!!*

These videos are awesome.

Aleks Udris has a phenomenal aviation knowledge.

Great videos. Just a footnote: a laser ring gyro does not spin up like the Appolo era mechanical gyros (yes, they are a product of the space race). A laser ring gyro only measures rate of turns on a specific axix. So you need 3 to measure all 3 axix. They use the Sagnac principle to measure constructive and destructive fringe interference projected over a sensor. They "align" instantly upon power-up. The time required for full alignement is only required to sense the Earth rotation to figure out the latitude and the True Heading. Very neat peace of hardware

Great presentation. Very informative.

Great presentation. Thanks

Excellent, Excellent, Excellent!
