I use a formula DA= PA + ( D x 120 ) and D = OAT - ISA.... Also, I just have one question while using the chart, is that if the QNH is 28.96 for example, we will need to calculate the PA 1st... but once someone told me that we will need to add or substract the elevation accordingly but it's "reverse"... for example if it is + we should substract and if it is + we should add the field elevation... Is it due to an exception ? or is it just way off and we should just apply as it reads ? .....
I have this same chart in my Gleim Private Pilot Book but and it seems to work great. I've also seen online calculators that factor in dew point. How does that affect DA and why is it disregarded in this chart?
cool video dude, the way I was taught ( with good mental math) is take the pressure altitude +/- (120 x T) where T is the temperature from standard temperature. It is a really quick way to do it in the cockpit. During the summer here in Utah with the field elevation of 4500 feet, on really hot days it was no surprise to see 7-8000 DA, factored in with low pressure and high humidity made you watch your power flying a robinson helo
hey great video. can you make a video about how to interpolate using this Density altitude chart?

you said 28.0 and are pointing at 28.8.... How do you know where to start out and does it change by itself while your in the air??

Wait,I thought this video was about a "dense attitude".I was sure it was gonna be about my ex-wife.

Very good Jason. Perhaps next time you can explore other ways to calculate DA. ex temp anwser x 120 = a... You know the one.
