Degraded / Jammed Elevator

A degraded or jammed elevator will result in less effective elevator maneuverability in pitch control. Center of gravity position with a jammed/degraded elevator The best position for the center of gravity with a degraded/jammed elevator…

Yaw and Roll Dampers

The purpose of a yaw damper is to (1) prevent Dutch roll and (2) coordinate turns. The purpose of a roll dampers is to (1) damp/remove Dutch roll, (2) provide roll damping in turbulence, and…

Flaps

Leading-edge slats Leading-edge slats increase the wing’s chamber area and mean aerodynamic chord (MAC), thereby increasing its coefficient of lift (CL) maximum, which reduces the aircraft’s stall speed. Krueger flaps Krueger flaps are leading-edge wing…


Spoilers

Spoilers

What are spoilers, and how do they work? Spoilers consist of opening panels that extend from the upper surface of the wing and have the effect of spoiling/disturbing the airflow over the wing (drag), thereby…

Control Surfaces

Primary/main flight controls Elevator: Controls the motion around the lateral axis, known as pitch/pitching. Ailerons: Control the motion around the longitudinal axis, known as roll/rolling. Rudder: Controls the motion about the normal/vertical axis, known as yaw/yawing….

Stability

What is directional stability? Directional stability is the tendency for an aircraft to regain its direction (heading) after the aircraft has been directionally disturbed (e.g., an induced yaw) from its straight path. This is achieved…

Aquaplaning / Hydroplaning

Aquaplaning is the phenomenon of a tire skating (not rotating) over the runway surface on a thin film water. It is caused by the buildup of a layer of water beneath the tire, which becomes…

Windshear and microburst

What is windshear? Windshear is any variation of wind speed and/or direction from place to place, including updrafts and downdrafts. The stronger the change and/or the shorter the distance within which it occurs, the greater…

The Right of Way

With two aircraft converging in the air, which one must give way, and how? When two aircraft are converging, i.e., at a constant relative bearing at the same altitude, the aircraft that has the other…
