One important thing this video (along with most other explanations of compass errors) leaves out is that the amount of error varies depending on the actual heading. He described the calculation for turning to 360 or 180 but ignored turning to 330/030, or 300/060, etc. Maximum error is experienced for cardinal north/south and reduces linearly until reaching zero at cardinal east/west headings.
I am doing check-ride prep for student pilot, and I was under the hood and my CFI covered both the attitude and heading indicator. I had me turn to headings and I had to use the compass and turn coordinator. He then had my turn in a VOR and it was not easy using the compass. Even when I timed it I was off.
I watching this video for flight school in Japan! There are no good Japanese explanation of this so I watch your video! Thank you for easy understand explanation
If a turning error is worst for northerly and southerly headings, and virtually non existent for east and west, then can one assume they’re proportionally less severe for NW, NE, SE, and SW? That is, your calculated under/overshoot should be decreased for headings less severe than 360 and 180. I suspect rolling out by your full overshoot value on a final intended heading of 100 would probably leave you pointed the wrong direction.
Thank you so much ! You should just inform that acceleration errors ANDS is only for northern hemisphere and its the opposite for the Southern Hemisphere ASDN
Would really like a video with your airflow animations to clearly explain why the inside wing has a higher AOA than high wing when doing a descending turn and the opposite when doing a climbing turn . This is not obvious and stories about spiral staircases have not helped the penny drop . I have a coupe of thousand GA hours and am still confused. The last video which would be great is to explain the couples when deploying flaps on a low wing ( nose pitches down ) vs high wing ( nose pitches up ) - This nearly caused my expiry when doing a conversion to highwing and on go around I was so used to pulling back on the stick when rotating with flap in first down position BUT on a high wing application of full power caused nose to pitch up + I was pulling back on the yoke - OOOPS !
Why can't man has been able to figure out something that can take care of these errors automatically. When you are already stressed because of the instrument failures, who will get that calculator out in their mind, while keeping a hand on the stick or yoke. Looks like Elon Musk needs to work on this challenge that going to moon.
It has already been solved. Modern aircraft and older aircraft with upgraded panels all have ADHRS (digital Air Data and Attitude Heading and Reference Systems) which were referenced multiple times in the video. These days, precise compass turns would only be needed as a backup in case of a systems failure while IMC. In an airliner that would be multiple simultaneous systems failures.
Please stop explaining magnetic field of flat earth plane surface on the ball... Ball is the projection of earth planar surface...not opposite... You are not flying on the ball... , 👎👎👎
Lol “don’t worry this is aviation and we have an acronym for everything”
It's true... Us pilots need all the help we can get. I do anyway. haha.
This man makes everything ten times more understandable.
It’s all untrue tho.

Thank you for sharing these outside of your school.
Greeeeeat explanation!!! Congrats for your work! I couldn't get a better explanation anywhere, I really appreciate it

Anyone find out the UNOS of this video was totally wrong?
I don’t even know anything about pilots and I just watch these videos because I got interested because of the runway video

I appreciated the humor in this video
Good video Dr. Thomas and crew!
This was very helpful! I love those acronyms
great review, thanks and keep them coming...
This is why the iPad and ForeFlight was created.
Long live Dr. Bob!

Compass points North as the center of Earth where the magnetic pole is.
Great video explaining ANDS & UNOS
For the southern hemisphere the common mnemonic is north is nippy and south is sluggish
No mention for visual land based confirmations needed having VOR radio communication.
pfff just on time!!! im doing prep for gnav exams and EASA is not kidding... :/ GREAT JOB BTW! :D
And ^THIS^, boys and girls, is "why" you should not ignore learning how to fly using the basics and with paper charts and an E6B.
We dont live on a globe but actually a topographical plane
best explanation !! loved

Thank you so much for this video I love it thank you very much and looking forward for new videos
Wizard Powers - 3:33
I needed this, thank you!!
At 2:24 it seems they think the globe has ±100˚ of latitude!
👍
Thanks. I was stuck
Big help sir. Thank u so much
Thanks a lot🙏💕
I understand it earlier,but didn't understand the southern hemisphere is different
Thanks a lot...😅😅
When it is pointing straight north is it at 0 or 36?
Both. It’s however you want to look at it. Both 360 and 0 are North. Most people look at it as 360 though.

It's because we are going into this with the presupposition that we live on a globe and that is simply incorrect.
So now you have to be a mathematician to use a compass?? 😂🤣😂🤣
First comment yay
Good
so confusing graphics
Please stop explaining magnetic field of flat earth plane surface on the ball...
Ball is the projection of earth planar surface...not opposite...
You are not flying on the ball...
, 👎👎👎
Blah blah, Just reading. Not all teaching is for everyone HHAHAA
