I can’t even express how grateful I am! If it wasn’t for your videos I couldn’t understand any of this! Honestly at this point I stop reading the book. I tried so hard and yet at the end of the chapter I felt so lost and confused 😐 Sometimes less is more, and is incredible how you can explain everything so well without being too technical and complicated! Thank you so much 🙏🙏🙏
Good job I became fond of this channel because there is no more memorizing without understanding thank you for deep explanation with illustration keep it up
Thank you Tim Allen for pointing out the mistake . I was starting to get frustrated with the math and questioning my competency. Other than that , this is a very helpful video.
This video is a godsend! However, why is it that in the example shown at 7:45 we compensate when turning *to* a North or South heading while turning errors occur when turning *from* a North or South heading?
many thanks for your videos and they are very helpful! I would like to ask for a clarification for the consistency/inconsistency at @11:15 and @14:35, which is for the opposite movement of compass card during a lagging turn of compass error. should the compass card in 14:35 will move to opposite direction (from 090/E to maybe 080) first, and then at a slower rate to the correct heading of 180? Many thanks for your help in advance! and i think we can also memorise the undershooting of compass direction by memorising it is for same direction for hemisphere and turning (NH+NT => lagging turn and hence undershoot), and same for SH+ST! cheersss
I am in a state of confusion, but something is telling me that there isn't a better explanation video for these magnetic compass errors so thank you for making the most sense. Jokes aside you're a real life saver!!!! 😆
Great video but I have some confusion. At 6:16 you talk about turning "from" a north heading but then at 6:55 the example talks about turning "To" a north heading. If turning from a north heading you would be headed north but turning to a north heading you would be heading East or West before that turn. Am I missing something or is this an error?
Why do the books (instrument flying handbooks FAA source) explains that in turns from the north, compass leads the turn and in turns from south it lags rather than lead? I am so confused by this… though I agree with your video it makes so much sense
PERSONAL NOTES Northern Hemisphere Turning from North heading - Compass will deflect to opposite side then turn in the right direction at low rate (Compass lags the turn) Turning from South heading - compass will move in direction of turn at high rate (Compass leads the turn) UNOS Turning into Northern heading - Undershoot North Turning into Southerhn heading - Overshoot South SOUTHERN HEMISPHERE Turning from South heading - Compass will deflect opposite direction then turn to the right side at a slower rate (Compass lags turn) Turning from North heading - Compass will turn into the right direction at a faster rate (Compass leads turn) ONUS Turning into a Southern heading requires undershoot Turning into a Northern heading requires overshoot
@Aviation Theory Hi! I have a question, in minute 4:40 why are those 2 compasses switched? if the plane is heading north, why is the nose of the plane pointing to the S instead of the N like it shows on the compass right next to the plane? same thing happens with the example of south heading, you guys put the nose of the plane pointing te N instead of the S
Hi Fernando, that’s because of the design of the compass itself. You can find more detailed information in this video: ua-cam.com/video/f2oMZdRuVBY/v-deo.html
can you answer one of my question? we are at 69 (east heading) in northern hemisphere. we need to go to 34 for which we had to turn towards north. if the compass lags 35 degrees then how will we compensate it here. As far as i know that when in northern hemisphere , we turn north, we must undershoot the lag from the desired heading, but i am confused with the numbers as if i had to reach 34 and it lags 35 , the heading must be 69 which is the current heading . so just explain me this by telling me exact heading
I'm still very confused. In a coordinated turn, the 'felt' force will be straight down relative to the plane (ie straight down into your seat as felt by the pilot) so why would the compass experience a force to the outside of the turn or a sideways force? If I understand the physics of an aircraft turning, then the only instance where centripetal force will cause a sideways force (relative to the aircraft) would be in a skidding condition
I thought that the bank angle of the airplane and thus the compass is what accounts for the magnet swinging in the opposite direction initially on northerly turns. At least that’s what King Schools teaches. Perhaps both the centrifugal force and the bank angle cause that temporary reversal in tandem?
If you undershoot North by 35 degrees, I believe your heading would be 325, not 335 as mentioned @ 8:45. Thanks for the video.
Thanks for the comment! I was thinking the exact same and got a bit confused.
You are right Tim! I made a mistake while making the animation of the video and it came out with 335 instead of 325, my fault.
thanks! i got the same question. LOL
Same question here thanks everyone it means that we payed attention
Exactly the same i was thinking
This is the only video on UA-cam that explains magnetic dip clearly...
Bravo! Nobody *explains* the physics of these phenomena. Memorizing acronyms for things you do not understand is not learning!
I can’t even express how grateful I am! If it wasn’t for your videos I couldn’t understand any of this!

One of the best aviation theory channels that really explains everything "on fingers". Bravo, your knowledge shared is precious.
Excellent explanation!!!!! Had an exam didn’t had a time to read just watch you video..
Very nice, I knew the results, not the reasons. Thanks!
One of the easily understandable explanation I have found online, thank you.
Good job I became fond of this channel because there is no more memorizing without understanding thank you for deep explanation with illustration keep it up
Awesome video! Explains everything step by step! Thank you! 😊
Now I understand !! Thank you had such a hard time with this topic :(
Thank you for making this beautiful effort !!

what was the confusion?
Thanks, that was amazing🙏🏻

I absolutly love your videos! They help me a lot to understand the ATPL meterials. Do you have a plan for the rest 11 exams?
PERSONAL NOTES
Northern Hemisphere
Turning from North heading - Compass will deflect to opposite side then turn in the right direction at low rate (Compass lags the turn)
Turning from South heading - compass will move in direction of turn at high rate (Compass leads the turn)
UNOS
Turning into Northern heading - Undershoot North
Turning into Southerhn heading - Overshoot South
SOUTHERN HEMISPHERE
Turning from South heading - Compass will deflect opposite direction then turn to the right side at a slower rate (Compass lags turn)
Turning from North heading - Compass will turn into the right direction at a faster rate (Compass leads turn)
ONUS
Turning into a Southern heading requires undershoot
Turning into a Northern heading requires overshoot

Hi Fernando, that’s because of the design of the compass itself. You can find more detailed information in this video: ua-cam.com/video/f2oMZdRuVBY/v-deo.html
thanks for asking this, I was also confused about this, after watching the linked video explaining the compass design it made much more sense.
that's why gyro and GPS are great inventions lol, it's a very good video anyway!
Awesome tutorial. Thank you
Thank you!
can you answer one of my question?
we are at 69 (east heading) in northern hemisphere. we need to go to 34 for which we had to turn towards north. if the compass lags 35 degrees then how will we compensate it here.
As far as i know that when in northern hemisphere , we turn north, we must undershoot the lag from the desired heading, but i am confused with the numbers as if i had to reach 34 and it lags 35 , the heading must be 69 which is the current heading . so just explain me this by telling me exact heading
Thank you so much
Great video, but the pivot point "moves" in relation"to the magnet, not the CG, the result will be the same so no worries.
I'm still very confused. In a coordinated turn, the 'felt' force will be straight down relative to the plane (ie straight down into your seat as felt by the pilot) so why would the compass experience a force to the outside of the turn or a sideways force? If I understand the physics of an aircraft turning, then the only instance where centripetal force will cause a sideways force (relative to the aircraft) would be in a skidding condition
13:58 031 will be after we've crossed the mark of 3. In the video its shown like 029. Amazing video otherwise, thank you so much.
thanks buddy
The north heading with the airplane looking south is throwing me off
Bravo
But the errors is calculated by adding the bank to the value of latitude and then /2?
Isn’t it?
you have northern hemisphere and southern hemisphere switched
Hi AD, what part of the video are you referring to?
Only half of the explenation!! What about the effect of the bankangle??? With this explanation you get the right answer but with the wrong reason
Magmatic and vision
The AI voice is somewhat annoying. Other than that, great videos.
This is only one piece of the story... There is no mention of the vertical components of the magnetic field...
Unos onus
TQ！
