Pressure Altitude : Everything You Need to Know

Hello and thank you for watching the ACS Library! Today's video is a little off script. We cover Pressure Altitude.
Pressure Altitude must be calculated in order to find Density Altitude. Pressure Altitude may also be used in Performance Calculations.
In this video we define Pressure Altitude, explain how to calculate Pressure Altitude, and provide an example problem.
I hope that after watching this video, you feel less pressure (ba-dum-tss🥁) in preparation for your checkride or flight review.
For those who would like to contribute to The ACS Library, I invite you to do so through Venmo. Just search @TheACSLibrary
Thank you for watching!

I just have to say this channel does gods work. Thank you so much for making these and more so for making them fre

Haha thank you Connor! I appreciate the big compliment

Really coming in clutch with the recent updates!

I have always been confused on whether or not to use the ambient pressure lapse rate for altimeter setting at cruise altitude and this cleared that up, thanks!

Thank you for taking the time to comment Jaden! Pressure/Density altitudes were so tough for me to grasp at first. I'm glad the video helped!

@cheapskateaviation 2 года назад

Thanks for another great video. That being said, it's probably worth noting that for most performance calculations, density altitude is much more important than pressure altitude.

@theacslibrary4404 2 года назад

Absolutely! I don’t think I’ve used a performance chart yet that doesn’t factor temperature into the mix.

this song fits perfect with your video title

duke c Thank you! Haven’t managed to find a good one for density altitude just yet though haha

why we add 220 im confuse 🤔

What is the pressure alt at a certain height? So if at sea level it reads 30.14, and im going up to 4500 ft, how do u find pa there

@theacslibrary4404 2 года назад

So at Sea Level it read’s 30.14. That means the pressure altitude there is -220 feet. To find pressure altitude at 4500’, just add that -220 to your desired altitude. At 4500, it would be 4500 + -220 or 4500 - 220. The pressure altitude in your area, at 4500’ MSL would be 4280’.

Totally off topic maybe I missed it but I don’t see a video on human factors? Also I’m done with the first half of the ACS library if you want in do you have an email I could shoot it over to?

@edpaulomcdonnell-velasquez970 Год назад

It has every video from 1 through weather theory

Using a calculator my numbers don't match at all.. There is something missing

@theacslibrary4404 3 года назад

Hi HavanaFly! Sorry to have taken so long to get back to you. The most common culprit would be being in Radians mode on the calculator instead of Degree mode. Please, let me know if this doesn't help!
