Thanks for the video. Really helpful. The only thing I would add to eliminate some confusion is that you alway keep standing pressure 29.92 on top when you are adding or subtracting from current pressure setting. For example, in the second example: it should be 29.92 - 30.42; which should yield-.5 x1000= - 500. This should tell you that you need to substrate this number from your field elevation and altitude you planned to cruise.
I've been having trouble grasping how this whole pressure altitude thing relates to real-world scenarios. Thanks so much for this simple and vivid explanation, very helpful. This will totally help with my upcoming FAA written test as well!
This was an easy trick that was helpful to me to calculate and be sure you get the addition or subtraction correct... Start with standard pressure at the top of the calculation(don't put the larger number at the top of your calc). For example, 29.92-30.42=-.5(x100=-500), subtract 500 from field elevation or cruise altitude. 29.92-29.42=.5(x1000=500), add 500 to field elevation or cruise altitude.
Please note that in the first example, I meant to show/say 29.42", not 28.42", which gives the 0.5 result/500'.
lol, I was just staring at that wondering what the math was. Good video
that last example is absolutely priceless 💡

Thank you for this video, it was very helpful.
Glad I could be of help.
Incredibly helpful
Glad you found it helpful.
Very good thanks!
Thank you too!
Thanks
EX 1 So, 29.92 - 28.42 = 500 ? My calculator says 1.5. Please explain.
Damn! Yes, I made a mistake. I meant to show/say 29.42", not 28.42". I will have to make a note about that.
