This video is a free walkthrough tutorial that explains high density altitude and its effect on aircraft performance in preparation for the sUAS FAA Part 107 exam for commercial drone license. The video goes over six typical questions on density altitude as part of the weather study topic that you can expect on your exam too.
I explain the difference between density altitude vs. pressure altitude and go over conditions when they would be the same or not. Also, I cover four factors that affect density altitude and aircraft UAS performance, namely barometric/atmospheric pressure, ambient temperature, relative humidity and altitude.
Most of the test questions and material I cover in this video come from the study guide I used to prepare and successfully pass the exam with a 90% score in 2022. Take a look at this study guide here (updated for 2024): 🔸 https://amzn.to/463UQrV
