Welcome to Aerominds Training Centre! In this video, we are covering one of the most important instrument topics for DGCA CPL students — The Pressure Altimeter, including the Simple Altimeter and the Sensitive Altimeter — explained in the easiest possible way. This is a core concept from Instruments and Technical General, and it is directly linked with performance, navigation, meteorology, and flight safety. Many students try to memorise definitions without understanding how the altimeter actually works. In this lesson, we will break everything down step by step so that even a complete beginner can understand it clearly. This session is specially designed for: Students preparing for DGCA CPL / ATPL exams Student pilots currently flying Ground school students struggling with altimeter errors And beginners who want concept clarity instead of mugging up notes In this video, you will clearly understand: • The basic principle of the pressure altimeter • Why pressure decreases with altitude • Why pressure and height are not linearly related • How weather and temperature affect altitude indication • Definitions of Height, Elevation, Altitude, Pressure Altitude and True Altitude • International Standard Atmosphere (ISA) and why altimeters are calibrated to it • How aneroid capsules work inside the instrument • How mechanical linkage magnifies tiny pressure changes • Temperature compensation inside the altimeter • Difference between Simple Altimeter and Sensitive Altimeter • Multi-capsule system and why it improves accuracy • Three-pointer system and gear ratios (100:10:1) • Jewelled bearings and knocking devices explained • Variable datum setting and pressure subscale window • Why turning the knob moves the pointer • Why climbing does NOT change the subscale number • Common student mistakes in reading three-pointer altimeters • Drum-type (counter pointer) altimeters and why modern aircraft use them • DGCA exam traps related to pressure, temperature, and misreading This video focuses on deep concept understanding with exam-oriented logic. You will not just learn what the altimeter shows — you will understand why it shows that reading and when it can be wrong. If you are serious about becoming a safe and knowledgeable commercial pilot in India, mastering this topic is non-negotiable.
