Why Your Airspeed Indicator Is Lying (IAS vs TAS Explained)

Most pilots think airspeed is simple—just read the indicator. But indicated airspeed is NOT your true airspeed, and that difference matters more than you think. In this lesson, we break down: Why your airspeed indicator doesn’t show your actual speed How temperature and pressure affect true airspeed The difference between IAS, CAS, TAS, and ground speed A real example showing why 100 KIAS can equal 110 KTAS How to quickly calculate TAS in flight Using a Garmin 430/530 to automate the process Understanding this is critical for: Performance calculations Navigation and wind correction Avoiding common pilot errors If you want a deeper understanding of airspeed, performance, and real-world flying techniques, check out the full course here: 👉 https://www.flight-insight.com/courses
