Magnetic Compass Errors: Turning

[@TimAllen7]

If you undershoot North by 35 degrees, I believe your heading would be 325, not 335 as mentioned @ 8:45. Thanks for the video.

[@addano84]

Thanks for the comment! I was thinking the exact same and got a bit confused.

[@AviationTheory]

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.

[@a0981921289]

thanks! i got the same question. LOL

[@yangojulianwuerazo4748]

Same question here thanks everyone it means that we payed attention

[@tanusharma1158]

Exactly the same i was thinking

[@vincentqiao5930]

This is the only video on KZbin that explains magnetic dip clearly...

[@Simonesanderss]

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 🙏🙏🙏

[@jlawrence3659]

Bravo! Nobody *explains* the physics of these phenomena. Memorizing acronyms for things you do not understand is not learning!

[@vadymaderkas2329]

One of the best aviation theory channels that really explains everything "on fingers". Bravo, your knowledge shared is precious.

[@yamanawrooz5132]

One of the easily understandable explanation I have found online, thank you.

[@karanpatel3918]

Excellent explanation!!!!! Had an exam didn’t had a time to read just watch you video..

[@robertryan2400]

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.

[@MrSam-db1vw]

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

[@aleshaswann6381]

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!!!! 😆

[@anirudhagarwal950]

what was the confusion?

[@user-up3pm2bb6q]

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?

[@joely112001]

Now I understand !! Thank you had such a hard time with this topic :(

[@EdytaNiemiec-sz5ew]

Awesome video! Explains everything step by step! Thank you! 😊

[@thundermustard]

Very nice, I knew the results, not the reasons. Thanks!

[@animesh06yt24]

Thank you for making this beautiful effort !!

[@josephgeoghegan7915]

Excellent tutorial

[@leidynatalia6737]

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

[@ferofiz]

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

[@shuiyul1464]

that's why gyro and GPS are great inventions lol, it's a very good video anyway!

[@Tomer-The-Pilot]

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?

[@billyhssin]

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

[@kamelghazouani2076]

Excellent explanation 🎉❤

[@BlueManRedManYellow]

This was very helpful. Great video

[@sbieramark1633]

Awesome tutorial. Thank you

[@firstdayonline]

Thank you!

[@CashMoney5280]

great content! i appreciate the knowledge Thank you!

[@MA-xf2lu]

Thank you so much

[@tanusharma1158]

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

[@igorpedras4761]

Great video, but the pivot point "moves" in relation"to the magnet, not the CG, the result will be the same so no worries.

[@fernandoponcedeleon7963]

@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

[@AviationTheory]

Hi Fernando, that’s because of the design of the compass itself. You can find more detailed information in this video: kzbin.info/www/bejne/nGPSfo2ah9qJeLs

[@dannymaisey4320]

thanks for asking this, I was also confused about this, after watching the linked video explaining the compass design it made much more sense.

[@abhisheksukhani9124]

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.

[@ViperVideo]

The north heading with the airplane looking south is throwing me off

[@tristanang5027]

thanks buddy

[@hanxie5634]

Bravo

[@carlovazer8487]

But the errors is calculated by adding the bank to the value of latitude and then /2? Isn’t it?

[@lorenz6703]

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

[@domijayawardena9495]

Magmatic and vision

[@eliassimon7947]

Unos onus

[@user-gl2fn1jd2f]

you have northern hemisphere and southern hemisphere switched

[@AviationTheory]

Hi AD, what part of the video are you referring to?

[@massimilianoc2436]

This is only one piece of the story... There is no mention of the vertical components of the magnetic field...

[@aslesterg5803]

TQ！

[@antongabrielson8544]

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?

[@JC-cw1ww]

The AI voice is somewhat annoying. Other than that, great videos.

[@braininavatnow9197]

Get used to it it's the new Norm

[@hmabboud]

Thank you!
