  Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Water on the Runway and Dynamic Hydroplaning

  Water on the Runway and Dynamic Hydroplaning Water on the runways reduces the friction between the tires and the ground and can reduce braking effectiveness. The ability to brake can be completely lost when the tires are hydroplaning because ... layer of water separates the tires from the runway surface. This is also true of braking effectiveness when runways are covered in ice. When the runway is wet, the pilot may be confronted with dynamic hydroplaning. Dynamic hydroplaning…

  Chapter 6: Flight Controls › Flight Control Systems › Servo Tabs

  airflow striking the tab counterbalances some of the air pressure against the primary control surface and enables the pilot to move the control more easily and hold the control surface in position. If the linkage between the balance ... fixed surface is adjustable from the flight deck, the tab acts as a combination trim and balance tab that can be adjusted to a desired deflection. Servo Tabs Servo tabs are very similar in operation and appearance to the trim…

  being disturbed. [Figure 5-21] • Neutral static stability—the initial tendency of the aircraft to remain in a new condition after its equilibrium has been disturbed. [Figure 5-21] • Negative static stability—the initial tendency of the aircraft to continue ... away from the original state of equilibrium after being disturbed. [Figure 5-21] Dynamic Stability Static stability has been defined as the initial tendency to return to equilibrium that the aircraft displays after being disturbed from its trimmed condition. Occasionally…

  Chapter 6: Flight Controls › Flight Control Systems › V-Tail

  This motion is called yaw. Like the other primary control surfaces, the rudder is a movable surface hinged to a fixed surface in this case, to the vertical stabilizer or fin. The rudder is controlled by the left and right ... slipstream flowing over the rudder increases its effectiveness. V-Tail The V-tail design utilizes two slanted tail surfaces to perform the same functions as the surfaces of a conventional elevator and rudder configuration. The fixed surfaces act as both…

  Chapter 8: Flight Instruments › Blocked Pitot System

  change due to the blockage; however, the static pressure will change. Because airspeed indications rely upon both static and dynamic pressure together, the blockage of either of these systems affects the ASI reading. Remember that the ASI has a diaphragm ... which dynamic air pressure is entered. Behind this diaphragm is a reference pressure called static pressure that comes from the static ports. The diaphragm pressurizes against this static pressure and as a result changes the airspeed indication via levers…

  Chapter 11: Aircraft Performance › Performance › Straight-and-Level Flight

  Straight-and-Level Flight All of the principal components of flight performance involve steady-state flight conditions and equilibrium of the aircraft. For the aircraft to remain in steady, level flight, equilibrium must be obtained by a lift equal ... Chapter 4, Aerodynamics of Flight, all parts of an aircraft contribute to the drag, either induced (from lifting surfaces) or parasite drag. While parasite drag predominates at high speed, induced drag predominates at low speed. [Figure 11-5] For example…
