- Everything you need to know about the magnetic compass as a pilot! In this video, I discuss turning errors and acceleration errors caused by magnetic dip. I also explain variation and deviation. This information will help you study for the Private Pilot written exam and the oral exam for your check ride. This training is intended to follow the aeronautical knowledge areas in Part 61.105 section b for single engine aircraft.

I’m in love with this channel! 95% of ground school for me was via an online course. These layman explanations are really driving home understanding. Thanks for all that you produce!
Awesome! I love hearing that! You’re welcome! More to come!
I learned more in this video than I’ve learned in the past 2 years with different CFIs. God bless you Josh. You’re the man 🙏❤️
Thanks! That means a lot!
@@FreePilotTraining ❤️
This is one that im going to need to watch several times.... More views for you!
Love it!
Thank you so much! These are the best aviation training videos on RUclips. Keep up the great work, it won't be long now before the RUclips algorithm catches on and your videos will start being recommended to a wider audience and you'll be getting a lot more views.
You’re welcome! And I REALLY appreciate you saying that! These videos are a lot of work, but I know that a lot of people are getting good training from them, so I’m going to keep pushing forward!
best dad jokes out there. please keep it up dude, am a dad and am loving it.
😆 Thanks! I’ll do my best
Awesome 🔥 Need more detailed videos
Well explained. For sure I will have to review the video multiple times. Even if it is all known, it is good to have it summarized so well. I am getting ready for the check-ride and the HI in the plane doesn't work so I always have to navigate by the compass. Old school yes, but more difficult. Thx for posting!
Thank you! Good luck on your checkride
Really well explained. i send my students your videos to study and understand
Awesome! Thanks for that! Weight and balance video coming soon!
Just to reiterate what has already been said, such great content and understandable explanations! I've been paying for online ground school and they just vomit information at me with no explanation. I find myself watching a video, then coming to your channel just to understand what i just watched. Keep doing what you're doing, you are making better and safer pilots! Providing a very valuable service that will directly benefit many pilots, and passengers!
Thank you so much! At some point I’m hoping to eliminate the need for online ground courses all together. 🤞
Clear and concise explanation, totally made sense. Loved the little extra with the cross country planning real-life example at the end. Awesome content, great delivery. Thank you so much!
Thanks! I appreciate that!
Another great video ✔️ Keep 'em coming 💪🏽
Thanks John! I’ll do my best!
Thank you, never knew compasses had so much lag/ over reading. Thank you for very useful acronyms!
You’re welcome! Thanks for watching!
thanks for explaining this!
You’re welcome!
Excellent explanation! Thank you.
You’re welcome!
Excellent channel. Thanks for sharing your expertise and experience with all of us.
Thanks! I appreciate that!
Best flight training channel. I always check here first if I can't understand something very good stuff!
Thank you so much
Nice job!
Thanks Jeff!
As always, thanks man!
You’re welcome!
Hey man, im going for a trial flight on the 29th June, i cant wait, as soon as i had my trial flight, im gonna book a class 2 medical, then take ppl lessons
So this is excellent information for me, its easier watching a video like this than it is ploughing through the ppl books, not that im not going to read them, but this gives me a greater understanding of what the books are trying to tell me
You’re gonna love it! Thank you so much! I’m the same way
Absolutely glad with his explanation, very understanding methods, congratulations 👏
Thanks!
First video I've watched out of 4 that explains this simply, great stuff as always man, thank you!
You’re welcome!
That's the best explanation of that that I've ever heard. VERY GOOD, SUPER COOL, THANK YOU!
I appreciate that! You’re welcome!
Nice explanation. Now subscribed!
Thanks Phil!
Best ground school youtube for ppl ever
Thank you! That means a lot!
Wow incredibly informative video!!! Thanks a lot. I've recently discovered your channel and it's just continuously playing on my phone lol.
Thank you so much! Glad you’re finding it useful! See you in the next one!
Great 👍
Awesome video!
Will watch it a few times to make sure I get all of that. LOL!
Thanks
Thank you! Yeah, it’s a lot to digest. And you’re welcome! See you in the next one!
These explanations are better than kings Ground School, thanks a lot.
Thanks! That means a lot!
Hey pal, absolutely love your videos. Thank you! ... I'm really having trouble understanding what you said, though, about these turning errors. I actually looked in the PHAK and it's seems you've described UNOS backwards. They way I see it; turning to north, the compass lags so you need to do the same in order for it to catch up/so that you don't fly beyond your intended heading. Turning south, again, the compass jumps ahead so you should go past the intended heading to compensate because the compass is way ahead of you. I have a few different sources of material laying in front of me that all seem to be agreeing with what I'm thinking. Unless, I'm truly out to lunch. I appreciate your time, bud.
'If a turn is made to a northerly heading from any direction, the compass indication when approaching north lags behind the turn. Therefore, the rollout of the turn is made before the desired heading is reached' - PHAK
Thank you! It looks like I did make a mistake here. All the examples are correct, BUT when I said that the compass will undershoot turns TO the north. That is wrong. It will undershoot turns FROM the north. It will overshoot turns FROM the south. Because of that YOU should Undershoot turns TO the North and Overshoot turns TO the south. I can’t believe I messed that up. Sorry about that. I need to get that fixed as soon as I can
@@FreePilotTraining No worries at all! I hated to say something but I was going nutz-o trying to make sure I had the correct info. Again, I really appreciate the content you provide. Thanks so much for the timely response! Take care
@@flygy481 i really appreciate you letting me know. I’ll have to get this fixed ASAP.
Good video! Check ride in less then month! These vids are short and to the point.
Thanks Bob! And good luck on that checkride!
@@FreePilotTraining Passed!! Your videos really helped get me over the finish line! Thanks again
@@firepilot109 Yes! Congrats! So happy these videos helped you!
Supposedly you can use the mag compass as an emergency turn indicator (if your T&B goes out or you don't have one) by flying a S heading, at least in smooth air.
That’s cool! I’m going to research that and maybe make a video! Thanks for the comment
These videos are such an amazing resource -- you're turning my RUclips procrastination time into productive ground school study time! Thank you so much for making these videos
Thank you! I love hearing comments like this! It’s so motivating
Great video, thank you.
The part towards the end of the video discussing magnetic deviation. When working on your flight plan, the Deviation only applies when flying using the magnetic compass correct? It would not apply when calculating the needed magnetic heading to use with an HSI in a glass cockpit, correct?
No problem! It applies when you use the compass and an analog Heading Indicator because you use the magnetic compass to set the HI. Digital HSIs use magnetometers
do I have to use this compass card everytime I make a turn ? or it's just important when it comes to update my heading indicator ? Thanks for the great content .
Nope just use it to update or when your heading indicator is inop
Learning a lot but this one might have burnt me. Lol
I’ve watched close to 6 hours of your videos today so that could be it. I really hope I’m shown this in plane while flying. I’m a hands on kinda guy. 🥺
Don’t worry. A lot of this will really click when you get in the plane. To be honest, some of this stuff (like this video) you won’t use too much. But you have to know how to do it for the checkride.
Not sure if it's just me but your drawings of N being red when you show the globe are different when you put the magnet on the compass. That also makes me not sure of where the heavy part is, when looking at the illustrations.
Thanks for the heads up. I probably need to remake this video at some point to make things more clear
if you are in straight and level flight regardless of your heading; do you still need to correct for compass errors apart from deviation errors.
No. They are typically not a factor in straight and level flight
I knew that, but I don’t remember why. I have been a pilot and a sailor. And helped a compass adjuster on sport fishing boats.
That’s cool! I guess all these things apply on the high seas as well
Thank you for all of these. I'm Terrible about sitting down and reading from a book, but hands on and videos, or "watch and try" work well for me. These are invaluable to aid in my ground school studies, and not agitate my ADD LoL. Keep up the awesome work!
You’re welcome! I am the same way! That’s why I started this channel. I just couldn’t find any training that was free, complete, and still watchable. Hopefully that will change soon 😏 thanks for the comment!
@@FreePilotTraining now if I could just get you to come to the midwest and teach me....😂😂
I scratch my head at this topic. I have a hard time memorizing this. I just know that the compass is only really accurate in straight and level flight. That's when I reset my heading indicator and then I use that.
Yeah, you will most likely not be asked about this
@@FreePilotTraining thank goodness!
Amazing video, hope it would help me in my check ride.
Thanks man! Good luck on the checkride!
One can't help wondering if there was a better design for the compass since all the knowledge was geared around the shortcomings of the design!
Maybe you could be the guy to invent it!
For turning error, what would happen if we turn right ?
Great video! Nice reminders as I head into my checkride.
And LOL re: the flat earth warning!
Thank you! Good luck on that checkride! Lol, I know...cracks me up
Now I'm prepared if I'm asked how much the turning error is for my flying area. Answer; 37 degrees. I feel smart now. Thanks :P
😂 you’re welcome!
A way I read to remember the difference between magnetic variation and magnetic deviation is to know variation comes from outside the airplane and deviation comes from inside the airplane, and deviants fly airplanes from the inside. Lol
Love that! Thank you! Lol
East? I thought you said "Weast"..
TOP OF THE EARTH? THE EARTH IS FLAT!
😂
I do
I do in my way ( B GD G)
as Eng done ! Today & tomorrow ?
Remember p.
How cruelly you Lee ! !
👆 dealing
With me ?
I forgive you / forget all
As usual / My Nature
But someone may not ?
Love the explanations but I can’t help feel like 1/2 the written is to learn tech no one uses anymore. Can we acknowledge computers and glass cockpits exist. 😂
So, the more I learn about all this stuff, the more important I see that it is. We are not taught why it’s important, and I’m working to change that
Just assume!
😂
And here's me thinking how complicated can a compass possibly be ?
Lol. It’s amazing how complicated it actually is
Coz
There is a Rule
Ya Rule? What Rule?
Otherwise that Rule
You can't ✈ 🍁
So I pray you GOD
save from that inevitable Rule.
E = mc² .
Ridiculous...you got a flat earth content warning? YT is absurd.
Great video just like the rest of them
Lol I saw that! I didn’t even say the words “flat earth,” but apparently their AI can identify that photo. That’s crazy to me. Thanks man!
Really good common sense instruction T V M D C
Thanks Chuck! Y W! See you in the next one!
The only problem is the examiner wants SIMPLE awnsers, otherwise more complicated questions. 🙄 Keep your awnsers short and simple, ANDS and UNOS.
So true. Make it painful for them by forcing them to ask for more details
What happens if you fly past the edge of the earth?
😂 that’s a great question... I’m assuming the airplane will fly better because there’s no gravity
This is incorrect. The compass overshoots turns to the north. You as the pilot need to undershoot to correct for this.
You must be in the southern hemisphere
@@FreePilotTraining no. That applies to the northern hemisphere. The acronym is to remind pilots what to do. Not what the compass is doing.
🚨 3:30 gotto play physics police: it can't be more weight on the left side because the right side is heavier as it is being pulled down more by gravity.
However the blue side is likely to have a higher moment of inertia (calculated by integrating mass over distance to the rotation point. This relationship is to the power of three!). Due to the higher moment of inertia the compass can sway more in a turn (moment of inertia is conserved or lost due to friction or conversion to other moment of inertia planes).
Dude, that is the whole premise in dip error. Try reading the Pilots Handbook of Aeronautical Knowledge. I’m not beyond making a mistake, but I didn’t just pull this concept out of my butt. It’s a proven concept that’s been around for years
@@FreePilotTraining what part didn't you get?
@RIB0S0ME The right side is not being pulled down by gravity, it is being pulled down by the magnetic field dip, explained at about 2:03
Why don't you just buy yourself a high-dollar compass won't that work
I really hope as a pilot you do subscribe to the flat earth theory
Lol. I wish I could believe it. There’s just not enough evidence to me
Seriously funny flat earth joke, dude! 😆
😂 I gotta make it fun
That’s not what happens in reality.
