What Is Bernoulli’s Principle? A Simple Guide for Pilots

Pilot Institute

Wing Camber Wing camber defines how much more curved the wings upper surface is compared to the lower surface. They adjust wing camber, thickness, and aspect ratio to balance lift, drag, and stall characteristics for different aircraft roles. Engineers try to design wings that maximize lift while minimizing drag.

Adverse Yaw Explained: A Pilot’s Guide to Better Control

Pilot Institute

The lift and drag imbalance between the left and right ailerons creates adverse yaw. This creates more lift and drag on the upgoing wing (left) and less on the downgoing (right) wing. The differential lift and drag are the main causes of adverse yaw. Any increase in lift causes induced drag to increase as well.

Everything You Need To Know About Ailerons

Pilot Institute

The asymmetry between the top and bottom surface of the wing is called wing camber. The downward movement of the aileron increases the asymmetry and, therefore, the camber while raising the aileron reduces the wing camber. The problem is that the aileron can only be deflected to a point after which the drag becomes significant.

The aileron on the right wing deflects down, increasing the camber and creating more lift. While the tilting lift vectors are an important source of adverse yaw, drag also plays a part. Any time a wing creates lift, it creates induced drag. This drag imbalance amplifies the adverse yaw. The lift imbalance causes the roll.
