GPS Navigation Explained (Private Pilot Ground Lesson 38)

You need to know this information to use a GPS for VFR flight! In this video, I explain how the GPS works. The basics of RAIM, WAAS, SBAS, and much more! This is Private Pilot Ground lesson 38! This training is intended to follow the aeronautical knowledge areas in Part 61.105 section b for single engine aircraft.

Just finished a binge watch of your PPL vids in the playlist. I'm honestly shocked these videos aren't pulling higher numbers. I'm doing some pre-ground school studying (funds are my limiting factor). And these videos are clear, and very concise. The production value is amazing, and I know I'll probably wind up rewatching these over and over as I practice the basics. Top notch work.

[@FreePilotTraining]

Thank you! I really appreciate that! I’m finally starting to get some traction with my videos. I’m hoping that things will really pick up speed once people like you find them valuable! Thanks for the comment and thanks for watching! See you in the next one!

[@carsongee1247]

Great videos. All of them are. I'm watching every single one from oldest to newest - i have a lot to go! It's great seeing so much local-to-me charts (from Stillwater, Ok)! Looking forward to acquiring my PPL!

[@FreePilotTraining]

Thanks Carson! Got my PPL in Tulsa and flew into there a few times! Great little airport!

[@theboogeyman1571]

Using your videos in tandem with King schools ground school. Words do not do justice for how pleased I am with the information you give in these videos. I find you fill a lot of the knowledge gaps in the King schools videos. All the best to you man.

[@FreePilotTraining]

Thank you so much! My first few videos weren’t the greatest, but I decided to invest the time, and really make something that can help other pilots out, and it’s really paid off

[@thomaslee1982]

As opposed to scaring me off, quite the opposite is true for me. Very clear and well paced presentation. Thanks for the good info.

[@FreePilotTraining]

Awesome! That is great to hear! You’re welcome!

[@dazknight9326]

I use a heading set in the directional gyro as a backup, written down on my knee pad. Then track GPS till around 20 miles out. Then when Airport in site, use a heading track in the autopilot to get squared up 90 degrees to runway, or straight in on approach after Airport in site. Then fly on in at TPA.

[@FreePilotTraining]

I prefer using the GPS track to get started, looking at the track then using the gyro. I think you have more control that way.

Your videos are extremely helpful for sure! If your primary target viewers are students without aviation experience, like me, "put on" the mindset of someone brand new to the material. I've tuned in to the best online ground schools and noticed a common theme: their explanations are filled with assumptions that the students/viewers already have some familiarity/knowledge of the material. This is entirely false! The trainer who successfully "puts on" the mind of a brand new student, simplifies all material/explanations, eliminates assumptions, slows down and uses bright colors (cursor, arrows, shading, etc) to show us precisely what you're talking about on the screen and where it's located on the screen...this will prove to be one of the greatest strengths of a training program like yours. Thanks for your commitment to training us newbies; hoping your subscriber numbers only increase!!!

[@FreePilotTraining]

Thanks Jim! Comments like this is why my videos continue to improve! At first, I thought everyone wanted a ground course they could watch for free that is similar to those on the market, but in reality, folks like you we’re looking to fill that knowledge gap! Thanks for commenting! It means a lot!

[@casperdecker4288]

Best raim explanation on KZbin!! 👍👍

[@FreePilotTraining]

Thank you so much!

[@davidclaiborne5280]

I just wanted to drop a note to say I’ve appreciated this entire series. Very clear and easy to follow presentation. Thanks for putting this together!

[@FreePilotTraining]

Thanks David! I really appreciate comments like this. It really gives me some good motivation! See you in the next one!

[@user-fd1uc5cj3e]

Great VOR description 👍🏼👍🏼👍🏼 “seya”

[@FreePilotTraining]

Thanks!

[@SeemaGul-yb8ud]

Nice

[@FreePilotTraining]

Thanks!

[@keithhoward9238]

Outstanding work and always informative 👏 👍

[@FreePilotTraining]

Thanks Keith!

[@hhazelton4391]

Again, very educational! I'm hooked dude . Thanks

[@FreePilotTraining]

Awesome! No problem!

[@mistervacation23]

The best scenario is the open-ended statement, they had no functioning Navigator by the time they took off until the time they crash-landed

[@hmabboud]

Thank you!

[@FreePilotTraining]

You’re welcome!

[@98DEB]

Thank you

[@FreePilotTraining]

You’re welcome!

[@TheMyrakkel]

The ole 135a hasn’t been updated since 2011. I am putting together a piggy back serial to try and get this done. It still seems pretty much accurate, we’ll see how close it gets once I nail down this database update.

[@FreePilotTraining]

Wow. 10 years. My garmin 300xl hadn’t been updated since 2015 when I first bought my plane, and there were airports that weren’t in there and some of them had different names lol. I had to pick something nearby to get it to take me in the right direction lol

[@guillermobarrios8605]

Dude where did you get the "see ya" from? Where you deployed overseas?

[@FreePilotTraining]

I have been deployed. It’s just something Air Force Pilots say sometimes lol

[@asdrty258]

Gps accuracy is about 30 m #dvor

[@truestopguardatruestop164]

I think I might have a correction at minute 1:00 (more or less). With just one satellite there is no way you can accurately tell the time distance between the receiver and the GPS satellite transmitter, since the GPS is one way non-communicating signal, there is no way for a back and forth to operate to measure the ping distance between the two. Said that, as I understood it’s not about distance from each single satellite, but from the relationship between the signals of various satelittes. You see: satellites know for sure their position in the space (adjusted by ground every once or so) and the exact time through very very precise atomic clocks. What GPS satellites do is to broadcast a signal every lets say “round second” (example 1:01:00000), all of them do. Then you receive these signals from the satellites on your reach at different times, depending on the distance of each satellite. Since the receiver doesn’t have a synchronized atomic clock, all it has is the relationship of times of each signal. With those and the position said by each satellite then triangulates the position. If I have a source that can unveil the mathematics behind this I’ll post in the comment section below. Anyways, great video as always!

[@FreePilotTraining]

Great points. Thanks!

[@heartstone1203]

Why do you think the gps tracking for the public, when plains flying over the ocean, on Long flight disepears. Isnt it a global position system?

[@FreePilotTraining]

Well, I’m not an expert on oceanic crossings, but I don’t think ADSB is required when crossing the ocean, and they turn it off when they’re flying over international waters. They should still have GPS out there, but the accuracy doesn’t have to be as good. Probably because there are fewer satellites in range

[@lokabanditt]

@@FreePilotTraining if you think about it its kinda strange. Since its sepose to be a saftynet if enything would happen to the plaine and the passangers over these travels. gps is Created by the USA defens departement. And dont you think they have the finance to go arround this "problem" regarding singals? I dont buy the not anough satelites thing. Cus is more then anough of them

[@FreePilotTraining]

@@lokabanditt once again, my answer is a total guess. I’ll try to do some more digging cuz I’m curious as well

[@lokabanditt]

@@FreePilotTraining let me know if u find a suiteble answer about the subject. I Will try to do the same :)

[@FreePilotTraining]

@@lokabanditt will do
