Instruments Navigation Aerominds - Air Navigation | Instruments | Chapter 4 - Airspeed Indicator (Part 2) | DGCA CPL NOTES AND EXAM MCQ

Welcome to Aerominds Training Centre! In this video, we cover one of the most important and most misunderstood topics in aviation theory — Airspeed Types (IAS, CAS, EAS, TAS) — a high-weightage and concept-critical subject for DGCA exams. This lesson is specially designed for students who are completely new to aviation and want crystal-clear understanding instead of confusing textbook definitions. You’ll learn: • What Indicated Airspeed really shows inside the cockpit • Why IAS is not the true speed of the aircraft • Instrument Error explained in simple words • Position Error and why airflow around aircraft causes it • How IAS is corrected to get CAS • Why aircraft limits are based on pressure, not speed • Dynamic Pressure explained like a beginner • Why stall speed stays same in CAS at any altitude • Why CAS is important for safety limits but not navigation • Compressibility Error explained simply • When compressibility becomes important (300-knot rule) • How CAS is corrected to get EAS • Why EAS represents true aerodynamic force • Density Error explained step-by-step • Why ASI underreads at altitude • How EAS becomes TAS • Why TAS is used for navigation planning • Complete correction chain: IAS → CAS → EAS → TAS • DGCA exam tricks, traps, and conceptual questions This video focuses on deep understanding and logical clarity so you can solve any airspeed question — numerical or conceptual — without memorising formulas blindly. Whether you are a student pilot, preparing for DGCA CPL/ATPL exams, or just starting your aviation journey after 12th, this class will build your foundation strong from the basics.
