What is RAIM | Receiver Autonomous Monitoring | How GPS Works

RAIM uses more than the minimum required number of satellites to perform checks on the position calculated, identifying faults in satellites and ensuring integrity of position reporting.

My CFII gives me oral exam practice questions after each training flight. Today's was: "explain RAIM". I choked. So I went home and reviewed this video several times. How is this (below) 30-second summary of FlightInsight's phenomenal 4+ minute presentation?
-- Receiver Autonomous Integrity Monitoring allows your airplane's GPS navigator to confirm that it's receiving a sufficient number of valid satellite signals to correctly determine its location and altitude, while rejecting any faulty signals from malfunctioning satellites. This assurance of positional integrity requires at least five functioning satellites in view. Various websites and applications confirm RAIM availability for our intended flight path and time. If RAIM is, or becomes unavailable, then GPS cannot be used for navigation. --

To be honest i tought this was harder to understand
and then this King appears and explain it to you easy under 5 min

I just can't believe the quality of this channel's videos. Everything is perfectly clear. Simplified but not overly simplified.

Dan- I have been digging into GNSS, GPS, SBAS, WAAS, RNP and PBN. Your newest video was very timely.
Now you need to sort out the alphabet soup of the aforementioned acronyms!!
I always learn something from your work- realizing how much I don't know!
Happy New Year!!

I love your videos! I'm studying for my instrument checkride and these videos make it so easy to review.

And this is probably the best argument in favor of WAAS. If you have a WAAS capable receiver you don't have to do RAIM predictions. (You probably should still do them, though, just in case.)

Thank you! I really appreciate all this knowledge you share with us. Very interesting!

[_Breakdown]

GPS system - - 0:27 - - requires reception of signals from a minimum of 4 satellites.
RAIM (Receiver Autonomous Integrity Monitoring) - - 1:56 - - requires a minimum of 5 satellites.
(Note - - separate video - - ADS-B requires a clear line of sight of 288 miles)

Is the Enroute-2nm, Terminal-1nm, App-0.3 to 350ft assured when we have RAIM availability? not a WAAS?

IN GPS RADAR THERE NEEDS TO BE 4 DIFFERENT SATTELIHTS AT A TIME?

[faaacademyairportcertifica]

IF ONE OF THE SATTELITES ARE MISAIMED THEN A FIFTH SATTELIGHT IS NEEDED? A FALSE POSITION IS GIVEN?

[faaacademyairportcertifica]

THE LEGACY CAN CALUCULATE IF RAIM IS NEEDED? IT CAN BE USED IN IFR BUT IF RAIM IS LOST THEN THEN APPROACH HAS TO BE CHANGED TO RNAV OR OTHER?

[JustSayNO]

While preparing for my instrument oral exam, I came up with this question. Hopefully somebody can answer:
If while flying an approach in IMC to an airport having only RNAV approaches, there is suddenly a RAIM flag during the approach, how do you fly the missed approach, since it too requires GPS navigation?
