Be careful of a "gotcha" on a checkride. LPV is not considered a precision approach for "planning purposes" ( Alternates), despite it having lateral & vertical guidance and a DA commonly as low as 200 AGL. Not to be categorized as a precision approach by ICAO. Although you do fly it the same way from a 'technique' perspective. You may file as an alternate airport if it just has an LPV and it's an acceptable alternate, but you have to use the non-precision 800-2 weather forecast minimums at ETA, if you want to file it as your Alternate airport on your IFR flight plan.
Finally, someone pointed out the significance of LPV not being considered Precision. I hadn’t previously heard and had not considered that as a result, you’d need the non-precision approach and respective alternate minima. Thank you for that.
On the G430 if WAAS fails there will be a flashing, yellow box at the bottom left of the screen that says INTG (which stands for integrity). In a G1000, it will give a couple different indications; a CAS message that says GPS loss of integrity approach downgraded, in the CDI it says the accuracy of the GPS (so if you were at LPV it would become LNAV/VNAV or LNAV), and finally the vertical guidance bar will change shape and color. These are the two avionics systems in use at AeroGuard Flight Training Center so we responded in regards to our fleet. Please consult the avionics manual for the specific aircraft that you operate for the most accurate information. We hope this was helpful!
Hi Nikita According to AIM 5-4-5(a)(7), the APV type approach is defined as a third category. Most confusion occurs because the procedure for conducting an APV approach is quite similar to a precision approach. That is further exacerbated by the ACS that allows for APV approaches with specific minimum criteria to be used in lieu of a precision approach for specific tasks to be completed on an IR practical exam. The reality is that it’s in a separate category, but practically it seems closer to a precision approach than a non-precision approach. Hope that helps!
Hi there! This does get a bit complicated and specific; Non-WAAS equipped GPS units may be used for IFR operations, and are limited to how they are certified, what other navigation equipment is onboard the aircraft, and the phase of flight the GPS is being used. AIM paragraph 1-1-17 has detailed information that will allow a pilot to better understand the requirements for GPS certified under TSO-C129 or TSO-C196(). These certifications are the non-WAAS certified GPS that still have functionality in the IFR environment. As a general rule of thumb, the use of non-WAAS GPS units are more limited than those with WAAS, but with proper RAIM verification, system functionality, and an alternate means of navigation (i.e. VOR) nearly every phase of flight can be completed using a GPS. That is true for both GPS procedures or as an overlay (i.e. flying a Victor airway with GPS instead of VOR). Hope that helps!
@@AllegeK If you have WAAS, and you complete a RAIM prediction for your flight, and there are no NOTAMs for RAIM during your flight (for your particular routing) then yes you can fly IFR without a VOR.
Hi there. According to AIM 1-1-18(c)(9)(a) it specifies “Code of Federal Regulations (CFR) part 91 non-precision approach weather requirements must be used for planning.” An example of this would be if a WAAS equipped aircraft is planning a flight that requires an alternate airport the pilot could select an airport with only a GPS approach but must comply with CFR 14 91.169(c)(1) and must assume only LNAV minimums are available. So even if the approach has an LPV minima line, for planning purposes, the pilot will assume only the non-precision lines are available. To further that example, the pilot should determine if there are non-standard alternate minimums for that approach first, if not, then the standards listed in CFR 14 91.169(c)(1)(i)(B) would be the weather minimums to use. Thanks!

Winner of the most acronyms of any video on UA-cam.

Explained well in short time
Indeed
Flying is complicated (at times). Good thing we have good teachers.
We agree, Beth is a great instructor! Glad you enjoyed the video
Building blocks!

Thank you, Jim!
Concise and exrremely valuable! Thank you!!
Does the GPS give a message if there is a WAAS failure like it does with RAIM?
On the G430 if WAAS fails there will be a flashing, yellow box at the bottom left of the screen that says INTG (which stands for integrity).

In your point of view, this third category of approaches - APV - is considered a PA or NPA?

@@flyaeroguard That was the most complete and fastest answer I could ever expect, thank you so much!
Great video....very well explained...but please its WAAAAS not WOZ .......thanks !!!!
Awesome 👏 Very informative! Thanks for the video
You're very welcome. Glad you enjoyed it.
is it illegal to fly using gps in ifr without WAAS ? just like you said?

@@flyaeroguard thank you so much! It helped a lot!
Then… does that mean you can fly ifr without vor receiver?

@@flyaeroguard Thank you so much again
Concise and informative. Really helpful Thank you 🙏🏽
You're so welcome!
Amazing content
Thank you!
When planning for lpv minimums at alternate airport, you DONT use standard non-precision minimums (800-2)…. You use lnav minima line…

Great breakdown of the approaches. You guys do a great job! I would only edit the grammar mistake at 2 minutes.... Localizer.
By using 3 or 4 abbreviations per sentence, it impossible to follow....... imo
Wow :)

It’s WAAS! Not WAZ🤦♂️🤦♂️
