Literally been trying to understand this magnetic dip error thingy for pass 24hrs and a lot of the other videos I watch can easily confuse new learner but your illustration hit the nail on the head. Thanks.
Total nerd here! DVMONA! Deviation errors - the errors associated with electromagnetic interference from electrical components in the aircraft Variation error - the difference between true north and magnetic north which is what the compass points to Oscillation errors - the errors associated with the magnetic floating and bouncing around in the kerosene-like fluid Magnetic Dip Errors - errors associated with the fact that the magnet has a weight on its southern end (when facing north) that counteracts the force of the magnet trying to dip down following Earth's lines of magnetic flux to magnetic north which then causes the Northerly Turning errors and the Acceleration/Deceleration errors. As the aircraft is accelerated or decelerated the weight on the magnet causes it to swing around backward/forward respectively, which is why the acronym ANDS came about. The magnet shows a northern direction when accelerating and a southern direction when decelerating. The magnet shows a northerly heading when turning away from it momentarily which is why at 1:50 we see the compass remain on about a 010 degree heading. When trying to roll-out on a heading can be tricky because of these errors. For example for a 360 compass heading, you would have to undershoot by 30 degrees and if rolling out on a 180 heading , you would have to overshoot by 30. The acronym UNOS came about from this to help us remember to undershoot north and overshoot south. -Via her boyfriend/CFII Cesar S.
Thanks for the inflight demonstration of this. I found it very hard to do well in the cockpit even after reading books and watching illustrated videos. Seeing it in action helps a lot!
This helped a lot. I was very confused with the Acronym UNOS for a very long time so I kinda pieced together 2 acronyms with NOSE. For the initial part of the turn, you want to use NOSE (North Opposite; South Exaggerated). Not needed beginning on West/East Heading. For the end stage of the turn, you want to use UNOS (Undershoot North, Overshoot South). Not needed ending turn on West/East Heading. To see how much you would turn: (30 degree latitude / 2) + 15 = 30 degree, so aim for 150 if aiming for 180 (South) and 330 (North) As shown in the video if turning from the West. Found this worked best for my IFR training, especially when trying to describe VD MONA.

This was super quick, simple, and helpful. Also really great quality and the explanations were so clear. Thanks!
Straight from the cockpit
Excellent effort and well explained video
Thank you

Whats true north?
First video with unos that made me understand the concept. Thank you!

great video...i asked my cfi about ANDS & unos, he had the same answer I did...only the definition?.......you nailed it! thank you.

Your “BAM” is so addictive man 😂😂
Rockin' the shirt, man! Givin' us just the tip. Awesome! Seriously... great stuff.
Beautiful! thank you so much my brotha! i have my ifr checkride in september and this was the part im most nervous about! im subscribing!
Clayton Licciardello I have my CFI check ride on 8/20. Hope to have time to make more videos after all that is done!
Thank you so much
Amazing
thanks a lot for the explanation!
BAM! Great video!
That was perfect! Thank you for the video! I appreciate it very much that you spent the time and money to make this!
Its tough using the compass on an ils because you cant really use the compass to make a 2 degree coorection
A "vertical card compass"
Lmao! Tbh the name brought me here
roll out heading on south and north= (latitude+bank angle)/2
