Propeller Turning Tendencies & P-Factor - Video Transcript . During takeoff, the air accelerated behind the prop, known as the 'slipstream', follows a corkscrew pattern. Very common is to adjust the glide by warping or adding small tabs to the flying surfaces (usually giving a large circular glide path), then adjust powered flight by adding down and right thrust (to counteract the left turning and climbing tendencies from torque, P-factor, and increased flying speed). Lift, magical as it may be, isn't perfect. We'll go over each of these in some more detail, but the four that we're going to focus on are torque, spiraling slipstream, precession, and what most people call P-factor (asymmetric thrust). Since the same left-turning tendencies of a single engine airplane affect a multi-engine airplane, counter-rotating propellers have been developed to help combat those tendencies. Here's how they work, and why you need right rudder during takeoff to correct them. The single engines like the Cessna are showing right turning tendencies instead of left turning tendencies. Step on the right rudder to cancel them out, and you'll maintain a perfect centerline throughout your takeoff roll.
