GPS/WAAS/RNAV/RNP - An Introduction
Вставка

- This is an introduction to the instrument pilot terms: GPS, RNAV, RNP, WAAS, and PBN. I know these terms can cause more than a little confusion for new instrument pilots and I hope this episode helps as a basic introduction.

The rabbit hole is what keeps getting me with RNP/GPS/WAAS. one of the last things slipping me up before my CFII Checkride. Thank you for this!!!
Welcome!
As a 53 year old instrument student this was so helpful, thank you! I thought I had a good handle on positioning systems but as with all things aviation learning related I continue to be humbled at every turn. This video puts a lot of pieces together and is so helpful as is all your content. There’s a lot here to digest but your presentation style is easy to understand and so helpful, thank you for making this video.
Yep, I hear you, Kevin. I really should have started this before menopause...
So glad you found it helpful!
Out on deployment right now and still studying for my instrument rating, these kinds of videos make me feel like I've still got an instructor helping me out. Great Video Seth!
Thanks! Stay safe!

Guys in the Northern Hemisphere rarely realise that there is no SBAS in the Southern Hemisphere…… the Northerners have been lucky to have SBAS for many years now. The first SBAS system for aviation in the Southern Hemisphere will be SouthPAN for Australia / NZ region……sometime in 2027!!!!! So the best approach service delivery you can get in the South is Baro VNAV…..no LPV or LP+V.
Enjoy your SBAS
Awesome video, wish I had seen this series before my IR checkride!
Best of luck with commercial!
@@SethLakeDPE passed commercial without any problems and just passed initial CFI yesterday!
Great overview, Seth! Really nice work staying out of the weeds and overwhelming us.
Thanks, I did my best. Hopefully it was helpful.
I was really need this kinds of story telling tutoring thanks!
Amazing podcast. Thank you Seth!
🙏
This is great information. Thank you for your work on this
Good to hear! Thank you for the feedback!
This was great information. Especially for an instrument student such as myself. Thank you!!
So good to hear! Thank you for the kind
Thank you for creating this channel and giving us so much valuable information, learning more from your channel than from collage
Great to hear!
I wish this video had existed when I was an instrument student! Great explanation
Glad it was helpful!
Great video, thank you so much!!
You're welcome!
You're welcome!
Great another informative video. I reached out today by text and voicemail
Great! Please send me an email at seth@vsl.aero
@@SethLakeDPE I did
Thanks!
Thank you so much!
How accurate is the advisory GS to LPV? In an emergency situation could the advisory GS be followed? Kind of a loaded question but as an instrument student it is something I am curious of.
In most cases, especially on a LNAV/VNAV minimum approach, it is very accurate. Feel free to always follow the GS, but pay close attention to intermediate altitudes and be very cautious following the GS after reaching minimums.
As a rule, when you reach minimums and have the runway in sight, you need to follow the visual glideslope.
@@SethLakeDPE Thanks for the response!
Glideslopes are only used on precision approach. I think you meant to advisory vertical guidance or glidepath
i'm still confused about RNav i read "The term RNAV in this context, as in procedure titles, just means “area navigation,” regardless of the equipment capability of the aircraft. (See FIG ENR 1.17-1.) " maybe i'm over thinking it when wanting to explain it in a checkride
You are correct. The term RNAV means area navigation. You can navigate via RNAV with many systems. GNSS is the most common and the United States version of GNSS is called GPS. LORAN was also a type of RNAV system.
I think the part I am confused about is you said we can see rnav as capability and rnp as containment. But the sentence I reads its just area navigation, regardless of the capability of the equipment. But I love your videos you paint a very clear picture I guess I am just still confused on rnav Because you have RNAV1, 2 and oceanic modes that seems like it keeps it contained
depending if you are on terminal enroute or oceanic or remote areas, I'm
probably making no sense.
@@lauram7463 I appreciate your keen interest! Let's tackle the confusion: RNAV (Area Navigation) is indeed about the capability to navigate between any two points, not tied to any specific equipment. Think of it as the 'what' - what your navigation system can achieve, like reaching various destinations (RNAV1, 2, etc.) in different scenarios (terminal, en route, oceanic).
Now, RNP (Required Navigation Performance) is the 'how reliably' - it ensures your RNAV system stays within certain boundaries or tolerances. It's like a quality check, ensuring your navigation is precise and alerts you if it's not.
So, if a navigation system can get you from A to B (RNAV), that's great. But it's only RNP if it can tell you, 'Hey, you're straying a bit too far from your path.' I hope this paints a clearer picture!
I am not looking forward to instrument training. LOL. Again, thanks for the great video/content.
I think instrument training is the most fulfilling training you can take. Your going to love it! Keep up the studying!
@@SethLakeDPE Oh I know, it will be great. I have already started a little bit. But can't get to deep in the weeds before PPL check ride.
terrible, you should have thought about what to say instead of winging it
Some people don't like that I don't use a script, maybe someday. Feel free to enjoy other content.
Now I want to go bowling 🎳 😊..great job , thanks Seth .
