This is an awesome explanation, I particularly like the arrows. Thank you so much!!! Such a great idea and never seen that anywhere else. Are there any explainer videos where "drift" is added into the mix? This seems to come up in all the exam questions.
Thank you. I am presently in the process of preparing a load more videos, which will be added to my new question bank which is due for release early in the new year.
Cat3C Just calculate it the other way around, the true heading of 123 degrees will give 127 degrees of magnetic heading (westerly variation is always added to true heading) the substracting the given -3 degrees of deviation will give 124 degrees compass. Calculating with the basic west is best east is least form PPL theory will give the same answer.
First of all, RTFQ! The question does not NOT start from a true heading, that is what we need to calculate, so you are starting from an incorrect position in the first place. We start from 124C. That established, a negative deviation is a WESTERLY Deviation. DEVIATION WEST, COMPASS BEST (or Magnetic least) 124C - 3W = 121M Next, VARIATION WEST, MAGNETIC BEST (or True least) 121M - 4W = 117T OK, supposing we did start from 123T: 123T + 4W Variation = 127M 127M + 3W Deviation = 130C (Oops, that can't be right!) The negative deviation is westerly NOT easterly, and the subtraction of deviation only works along CDMVT when going from left to right. Instead of starting from 123T and explaining how you have then come up with 124C, please explain how you have started with 124C and come up with 123T. Maybe I can explain better where you've gone wrong. Are you using the reverse mnemonic TVMDC? The CDMVT 'arrow method' as shown in the video is unbreakable, provided you follow the (very simple) rules. I have been using it to teach ATPL students for the best part of 10 years.
The true answer is 117°. Here is an other explanation. Our instructor taught us an other technique. T = True heading VAR = Magnectic Variation M = Magnetic heading DEV = deviation C = Compass heading "
Best explanation ever! These videos are a gold mine!
@Cat3C
Sir, please make more content....❤
You are just a true blessing that I found on youtube!!
i had to leave a feedback. you have always explained things very well. props to you. and wish to learn more from your videos.
Most beautiful explanation ever..😭💥❤️
what a brilliant explanation
Best explanation and a very easy question

@@taffpike4277 Wonderful - you're doing a great thing. Amazing clarity.
Amazing ❤
Brilliant
Obrigado
Thank you Very Much Dear Captain
T V M D C
so nice
Thank you sir
Go to atplontrack.com and see my other GNAV and other explanations. I will be adding more videos to atplontrack.com in the very near future.
I find the milk not so relatable, i use - (C)an (D)ead (M)an (V)ote (T)wice?
This answer is just wrong, correct answer is 123 T.
I just love it when someone makes an absolute statement such as "THIS IS WRONG' without providing an explanation.
Over to you!
