Understanding the 4 main types of flaps (and why they matter): Flaps aren’t just for landing slower, they shape airflow, control lift, and affect how your aircraft performs during approach. Here are the key types you’ll need to recognise (and understand for the exam): • Plain Flap – Hinged at the trailing edge. Simple design, increases lift and drag. • Split Flap – Lower surface deflects independently. Creates more drag, useful for steep approaches. • Slotted Flap – Air flows through the slot, d

Do you actually understand the 4 types of drag? Most students memorise the terms… but few can explain what they actually mean in the exam or cockpit. Here’s the breakdown: 1. Parasite Drag Caused by parts of the aircraft that don’t contribute to lift, like the fuselage, antennas, or landing gear. The faster you go, the worse it gets. 2. Form Drag A type of parasite drag caused by the shape of objects. Think of the difference between a streamlined fairing and a flat surface facing airflow. 3. Ski
