It's pretty much impossible to explain aerodynamics without heavily simplifying it. Aerodynamics is a field for engineers, based on differential equations that don't have much use in the cockpit.
When you bank while maintaining altitude, your stall speed increases. It's something that you need to be aware of, especially when you're in the traffic pattern. So why does stall speed increase when you start rolling left or right?
If you've ever flown an airplane at max gross weight, you've definitely noticed a decrease in climb performance compared to when you're light. Here's why it happens.
Have you ever seen your descent rate exceed 1,000 feet per minute on an instrument approach? Here's why you should take corrective action if it happens.
You're flying an ILS through icing conditions and your airspeed suddenly begins decreasing. Your pitot tube is covered in ice. What would you do? Here's what happened to this pilot.
