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!!!

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.

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

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.

@SethLakeDPE 2 жыл бұрын

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.

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

@SethLakeDPE 5 ай бұрын

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.

@lauram7463 5 ай бұрын

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.

@SethLakeDPE 5 ай бұрын

@@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!
