Thanks goodness for this video. I finally have the answers I'm searching for without trawling through books and notes for hours! (CPL holder student pilot training for ME IR, who apparently has forgotten most of the Radio Navigation subject!) Thanks again!
Thank you so much! You helped simplify and clarify all of these concepts in just 8 minutes (ps. I'm a pilot and this helped me to prepare for some interview questions)
Sorry, but I think that's partially wrong. You're right about RNP routes requiring onboard monitoring and alerting about navigation performance deviations, but both RNAV- and RNP-approved aircraft should maintain flight within the navigation specification for at least 95% of the time. That's a PBN requirement and, nowadays, RNAV and RNP are both encompassed by the PBN concept (ICAO Doc 9613 Third Edition).
@@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.
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 keep missing what's the difference between RNP and PBN. Is there a chance that you could make a video about the difference? Also, why do LNAV and VNAV show a DA on the charts, even though they're not precision approaches? 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
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
For ILS and LPV approaches - why use the barometer height rather than the DH (radio height) if the barometer height can change? Why not just use RA (DH) all the time ?
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.
HOT tip to anyone making youtube videos. No one is going to subscribe because you asked them too. You get subscribers from making top tier content. Not from asking nicely. Kind of pointless.

Glad it was helpful! best of luck on your IR
2:00 for the definition, 5:00 for the approaches.
Its really good one. Simple, clear, no tonns of unnecessary info. Thanks a lot!
Thanks for watching, I am glad you liked it
Excellent video bro.

Brilliantly explained thank you sir

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 for the clarity of this information !
Glad it was helpful!
great show. when do you use a RNAV approach and when do a RNP approach
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.
Great presentation. Thanks
You are welcome!
Good overview.
excellent video
I am glad you liked it. thanks for watching
Good briefing
Thank you
Thanks for this video! It is too benefitly for me!
You are awsome . Greetings from PERU .
Hey, thanks!
I got my checkride tomorrow hopfully this will help, thank you!
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
Well done. Thank you.
Our pleasure!
Thank you
You're welcome
Nice job!!
Thank you very much!
You are most welcome dear

I have never heard of an IRS being used for RNAV capabilities. Can you explain this?
All your videos are great mate! Keep it up
Thank you for your comment. I am glad you found it helpful
Thank you!
I am glad you've found it helpful
Superb video, is helping a lot with the IFR ground school, but most importantly that it is staying in my mind
I am glad you liked it, best of luck on your Ground School
Excellent video. Just one thing to add. LOC BC is also non-precision approach 😊
Read about it in chapter 1 of the AIM, but still wasn’t too clear for me. This video helped a lot. Thanks!
Glad it helped!
Good video. Some minor details are incorrect though.
Thankyou very much for such an amazing explanation ✨😍
I am glad you liked it
The certification process is a pain , depending on FOI. Been there, done that!.stick to ILS,
Thank you for sharing
sir, what is WAAS?
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
How much does it cost to be a pilot in Qatar ?
For ILS and LPV approaches - why use the barometer height rather than the DH (radio height) if the barometer height can change? Why not just use RA (DH) all the time ?
Here where I’m doing my training, for example, there is always a notam saying that RA is unreliable.
@@lucascardinfranco2011 Ah - thanks.
Thanks for this😁😁
Welcome 😊
What is GPS baro-aided?
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…
LP?
Localizer Performance, similar to LOC but SBAS based

😍😍😍😍😍😍
👍👏👏👏👏
Do you guys also hate digging trough the easa documents?
Most of us are guilty of it
I'm not sure it this is now incorrect as approaches the were RNAV in Europe and now labelled RNP and what was RNP is now RNP-AR (RF legs)
Indeed, the terminology is changing

A gentle reminder though wouldn't hurt, Thanks for your comment
I’m struggling. Anyone knows if I can do an “RNP” approach with a C172?
