The surface area of the horizontal stabilizer, often referred to as the tailplane, on an aircraft can be calculated using basic geometric principles. The horizontal stabilizer is an essential component that provides stability in the pitch axis. Here’s the formula, definition, and SI unit:
- Surface Area of Horizontal Stabilizer:
- Measure the length of one horizontal stabilizer (from the root to the tip).
- Measure the width of one horizontal stabilizer (perpendicular to its length).Calculate the surface area of one horizontal stabilizer using the formula:
- Multiply the surface area of one horizontal stabilizer by the total number of horizontal stabilizers on the aircraft (usually one) to find the total surface area of the horizontal stabilizer.
