Lift Coefficient
The Lift Coefficient is a number that tells how well an aircraft's wings or other parts can create upward force (lift) during flight. Think of it like a report card for how effectively a wing design performs. Engineers use this measurement to compare different wing designs and predict how well an aircraft will fly. It's similar to measuring how well a boat floats or how aerodynamic a car is. When you see this term on a resume, it usually means the candidate has experience in aircraft design, wind tunnel testing, or computer simulation of flying vehicles.
