Also doing my ATPL and this was such an incredible video, I gave it to all my friends doing RNAV. The few aviation videos on this channel are by far the most elite videos for learning! Thank you so much

Awesome help

thank u for this video. currently in my rnav studies for ATPL and my mood was at least 10 times to frisbee my laptop into the wall..... thank u for explaining it in a way i can understand...

Happy your laptop is still intact :) Thanks for watching!

Rohde & Schwarz saving the day. Love that company

We have been using using GPS and SBAS for instrument approaches for decades now. SBAS was supposed to replace Cat 2 and 3 ILS but I guess it hasn't caught on.

First time commending ... gograts on the quality of your videos...i will sure suggest your channel with my fellow student colleagues

5:11 That's Sydney Airport YSSY

Yep - good catch! I believe Sydney was the first airport in the southern hemisphere to implement GBAS (trials with Qantas starting in 2012, fully operational in 2014).

SBAS can provide guidance for an equivalent CAT1 precision approach?

No, it's not possible. SBAS is used as a RNAV/RNP approach, with LPV minima or even LP minima. When you join the final approach, it usually shows WASS displayed on your equipment.

I take issue with the statement that non-augmented GNSS does not have sufficient accuracy or reliability for aviation. That just isn’t true. The level of position accuracy required is dependent on the performance based navigation requirement (RNP) of the phase of flight or approach being flown. In enroute airspace or for the purpose of flying a non-precision GNSS approach, augmentation is NOT required but that has to be considered in the approach design. Obviously GNSS based precision approaches will require GBAS but that is a very specific instance. I live in Australia, we do not have SBAS, we fly IFR and shoot approaches IFR using GNSS every-single-day.

I was under the impression that WAAS, which has an accuracy of approximately 1 meter, CAN be used for conducting precision approaches. Every other instructional video and text that I have read says so. Is this video outdated or incorrect, or am I incorrect in my understanding?

Good question: I would refer you to the FAA AIM, section 1-1-20b. Specifically: "A class of approach procedures which provide vertical guidance, but which do not meet the ICAO Annex 10 requirements for precision approaches has been developed to support satellite navigation use for aviation applications worldwide. *These procedures are not precision* and are referred to as Approach with Vertical Guidance (APV), are defined in ICAO Annex 6, and include approaches such as the LNAV/VNAV and localizer performance with vertical guidance (LPV). These approaches provide vertical guidance, but do not meet the more stringent standards of a precision approach. *Properly certified WAAS receivers will be able to fly to LPV minima and LNAV/VNAV minima, using a WAAS electronic glide path, which eliminates the errors that can be introduced by using Barometric altimetry."* [Emphasis mine]

@@pauldenisowski Thanks for the reply! I went to that source (AIM 1-1-20b) and I can't find anything that you just wrote. That section talks about the issuance of special instrument approach procedures under certain circumstances and who they should contact to receive special IAPs. But I did do some digging on the interwebs and found that WAAS is not a precision IAP, even though properly equipped GPS receivers with WAAS capability can descend to LPV minimums on an MDA approach. It's all jogging my memory from my Instrument rating days. 🙂

@@ianperry9571 Sorry, the section is AIM 1-1-18b (edited my original reply). Both FAA and ICAO seem to have a very specific definition of what constitutes a "precision" approach. Clearly WAAS provides some substantial benefits for approach, but GBAS takes the application of GPS in aviation to another level (no pun intended :)) Thanks again!
