Servo tabs are small control surfaces used to assist in moving larger control surfaces (such as ailerons, elevators, or rudders) to reduce the control forces required by the pilot. The surface area of servo tabs can be calculated using basic geometric principles. Here’s a formula to calculate the surface area of servo tabs:
- Surface Area of Servo Tabs:Measure the length of one servo tab (from the root to the tip).
- Measure the width of one servo tab (perpendicular to its length).
- Calculate the surface area of one servo tab using the formula:
- Multiply the surface area of one servo tab by the total number of servo tabs on the aircraft to find the total surface area of the servo tabs.
