The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces. If rudder is continuously applied in level flight the aircraft will yaw initially in the direction of the applied rudder – the primary effect of rudder. After a few seconds the aircraft will tend to bank in the direction of yaw.
Any rotor system has a delay between the point in rotation where the controls introduce a change in pitch and the point where the desired change in the rotor blade's flight occurs. This difference is caused by phase lag, often confused with gyroscopic precession. A rotor is an oscillatory system that obeys the laws that govern vibration—which ...
Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...
Like the Airbus system, this state is entered when a number of failures occur in the EFCS or interfacing systems (e.g. ADIRU or SAARU). Moreover, in case of a complete failure of all PFCs and ACEs, the ailerons and selected roll spoilers are connected to the pilot controls by control cable, permitting mechanical control on a temporary basis. [5 ...
A control system includes control surfaces which, when deflected, generate a moment (or couple from ailerons) about the cg which rotates the aircraft in pitch, roll, and yaw. For example, a pitching moment comes from a force applied at a distance forward or aft of the cg, causing the aircraft to pitch up or down.
Abstract representation of a Fly-By-Wire flight system. A flight control computer (FCC) is a primary component of the avionics system found in fly-by-wire aircraft. It is a specialized computer system that can create artificial flight characteristics and improve handling characteristics by automating a variety of in-flight tasks which reduce the workload on the cockpit flight crew.
Adverse yaw is a secondary effect of the inclination of the lift vectors on the wing due to its rolling velocity and of the application of the ailerons. [2]: 327 Some pilot training manuals focus mainly on the additional drag caused by the downward-deflected aileron [3] [4] and make only brief [5] or indirect [6] mentions of roll effects.
In more modern aircraft, inputs may first be sent to a fly-by-wire system, which then sends a corresponding signal to actuators attached to the aileron booster systems and control surfaces. Yokes may feature a stick shaker , which is designed to help indicate the onset of stall , or even a stick pusher , which physically pushes the yoke to ...
