In the 3rd video of the instrument mastery series, I explain the Vertical Speed Indicator, or VSI. This does what its name suggests. It tells you your vertical speed, and while not required, it's sure nice to have. I explain how it works, and how it behaves if there's a malfunction. After watching this video, you should know what you need for your FAA exam and real life.
121.Mike is all about flying. You'll learn what you need to pass your FAA knowledge tests and how to apply this knowledge.
