Quickly Learn the differences between ILS, LNAV, LNAV/VNAV, and LPV approaches. Instrument Landing System, or better known as ILS, are very similar but one is ground based and one is satellite based but look almost identical. LNAV, or lateral navigation provide guidance along a course, but add vertical navigation (VNAV) and vertical guidance can be given to achieve lower minimums (most of the time). LPV approaches mimic and ILS approach with the pseudo localizer gaining sensitivity as the aircraft approaches the runway.

Short but informative. Amazing!
LPV is still considered a NPA though. If you want to know more, there’s a great boldmethod live video about PBN which is a commonly misunderstood concept in my opinion. Nice short!
LPV is a non-precision approach but is actually classified as an APV approach which is an approach with vertical guidance in the United States. Some countries do consider it a precision approach.
Short and sweet!😁🛫 and to the point! Of touch down hopefully!
Shortest and sweetest
Thanks
Great video!!!
So the LPV is the ILS based on GNSS?
Yes, same indications as the ILS for the most part, but LPV usually has slightly higher minimums.
Make a isolate video on it
LNAV/VNAV needs WAAS doesn’t it
Not if Baro-VNAV equipped.
Here is the source for that answer: LNAV/VNAV approaches provide both horizontal and approved
vertical approach guidance. Vertical Navigation (VNAV) utilizes
an internally generated glideslope based on WAAS or baro-VNAV
systems. Minimums are published as a DA. If baro-VNAV is used
instead of WAAS, the pilot may have approach restrictions as a
result of temperature limitations and must check predictive RAIM
(Receiver Autonomous Integrity Monitoring).
See AIM 1-1-19, 5-1-16, and AC 90-105.

@@thecorporatepilotdad wow thanks for responding so quick! I have my CFII check tomorrow so this was very much appreciated
@@connorjensen2784 I just happened to be sitting at the computer when you left the comment. Best of luck on your CFII ride tomorrow. CFII is one of the easier checkrides (IMO).
Thanks for the video! What about RNAV? 🤔
RNAV/GPS approaches are the approaches with LNAV, LNAV/VNAV, and LPV mins.
@@thecorporatepilotdad Thanks for clarifying that! Cheers
Erm, some LPVs take you down to 200 AGL
Who said they didn’t? The LPV in the video has higher minimums.
@@thecorporatepilotdad Got it, you were talking about specifically these two approaches, I thought you were talking about what the typical mins are for each type of approach. My bad.
@@alexkochikyan nope, just the approaches in the video. No worries.
my new lord and savior corporatepilotdad at it again helping me through training 🙏🙏
You may have said it before this comment, but are you currently doing real world flight training?
@@thecorporatepilotdad just got my ppl about to start my instrument training
@@Deanjacob7 That is great. The instrument ticket is easier in my opinion. There are new regs to learn, different procedures, but for the most part, you're doing what you already know how to do. MSFS is a great tool in doing instrument training but be careful to NOT develop procedural bad habits in the sim that can be carried over to the airplane.
@@thecorporatepilotdad I appreciate your help
which is more efficient an ils or lpv?
LPV approaches can provide a reduced workload in the event of a missed approach by not having to change nav sources. GPS based approaches are not subject to interference from aircraft taxiing in front of antennas, and last of all, GPS based approaches are far cheaper to install than a ground based ILS system.
thank you@@thecorporatepilotdad
