🔴 RNAV & RNP THE DIFFERENCE EXPLAINED FOR PILOTS (2023) 

You are welcome!

Charles, Excelente observation. Congratulations! I have a question: Are RNAV and RNP considered a PRECISION APPROACH?

Just ILS

@@rivaldodasilvaalvesjunior9759 No. They're considered an "APV" (Approach Procedure with Vertical Guidance), according to ICAO, which lies between Precision Approaches (PA) and Non-Precision Approaches (NPA). I might be wrong, but I understand the concept of precision approach requires an electronically-generated glide slope, from an outside antenna, like a GS in an ILS. Hence, the ILS is the only PA.

​@@rivaldodasilvaalvesjunior9759no, hence higher minimums at some AD. They're Quasi -ILS. Or Quasi-GP.

@@santiagolozano5454 No, according to ICAO PANS-OPS ILS, MLS and GLS are precision approaches, but also LPV SBAS CAT I aka LPV200

Thank you

Any approach that is flown using the CDFA technique (Constant Descent Final Approach) has got a DA for minimums even if it's not a precision approach. Also please keep in mind that we no longer refer to Approaches as Precision or Non precision anymore. But rather, 2D approach (provides only lateral guidance) and 3D approaches (Lateral as well as vertical guidance). as for your first question I suggest you watch the video I have recently uploaded, it explains the difference perfectly. but in short, PBN (Performance Based Navigation) is the "umbrella" so to say under which RNP and RNAV requirements fall. PBN is a set of rules, whereas RNP is a set of accuracy and integrity and continuity of the onboard systems that will qualify you to maintain a specific accuracy in a specific airspace or area. Hope this helped

Thank you for sharing

Glad it was helpful! best of luck on your IR

Here where I’m doing my training, for example, there is always a notam saying that RA is unreliable.

@@lucascardinfranco2011 Ah - thanks.

Wide Area Augmentation System is type of SBAS (Satellite Based Augmentation System) used in the US. I have made a video explaining all about it, check out my channel

A gentle reminder though wouldn't hurt, Thanks for your comment

Thanks for watching, I am glad you liked it

Indeed, the terminology is changing

Glad it helped!

Most of us are guilty of it

Nowadays the names are being used interchangeably. However, keep in mind that RNAV (RNP) approaches are RNP AR (Authorization Required). other RNAV approaches (LNAV, LNAV/VNAV, LPV) are RNAV GPS (SBAS or RAIM) based.

I am glad you liked it

Good luck!! you can do it

@@ATPLStudent it did go well, and now im watching for CFII lol. thanks again!

@@omarfaris8273 good luck mate you got it :) Im here for the radio navegation atpl exam still ahah

Hey, thanks!

Glad it helped!

Glad it was helpful!

I am glad you liked it. thanks for watching

I am glad you've found it helpful

Localizer Performance, similar to LOC but SBAS based

You're welcome

You are most welcome dear

Thank you for your comment. I am glad you found it helpful

Our pleasure!

Welcome 😊

It is an approach where the lateral guidance is provided by the GPS while the vertical guidance is provided by a computer that uses pressure changes, hence the name “baro” to calculate the vertical profile.

@@ATPLStudent how can I now that the aircraft is baro-aided? We use a DA-40 and I can find the waas and raim in the gps database.

Check your aircraft flight manual…..there should be a supp that covers what you can do with your installed system…

I am glad you liked it, best of luck on your Ground School
