Four Aerodynamic Forces • Lift • Thrust • Drag • Weight • When are they in equilibrium?
Bernoulli’s Principle • As the velocity of a fluid increase, its internal pressure decreases • High pressure under the wing and lower pressure above the wing’s surface
Controlling Lift • Increase airspeed • Change the angle of attack • Change the shape of the airfoil • Change the total area of the wings
Angle of Attack • Directly controls the distribution of pressure acting on a wing. By changing the angle of attack, you can control the airplane’s lift, airspeed and drag.
Angle of Attack • Angle of attack at which a wing stalls remains constant regardless of weight, dynamic pressure, bank angle or pitch attitude.
Flaps • Plain • Split • Slotted • Fowler
Ground Effect • Within one wingspan of the ground • An airplane leaving ground effect will experience an increase in what kind of drag?
Drag • What kind of drags rate of increase is proportional to the square of the airspeed? • Parasite Drag • What kinds of drag make up parasite Drag
Load Factor • Ratio between the lift generated by the wings at any given time divided by the total weight of the airplane.
Load Factor • A heavily loaded plane stalls at a higher speed than a lightly loaded airplane. • It needs a higher angle of attack to generate required lift at any given speed than when lightly loaded.
Aircraft Stability • Achieved by locating the center of gravity slightly ahead of the center of lift • Need a tail down force on the elevator
Turns • The horizontal component of lift. • Load Factor and Turns • The relationship between angle of bank , load factor, and stall speed is the same for all airplanes
Density Altitude • High • Hot • Humid
Surface Winds • Headwind or tailwind component • a 10 knot headwind might improve performance by 10% • a 10 knot tailwind might degrade performance by 40%
Performance Charts • Experience Test Pilots • Factory new Airplanes • Repeated Tests using Best Results • Format -Table -Graphic
Cruise Charts • Range is the distance an airplane can travel with a given amount of fuel • Endurance is the length of time the airplane can remain in the air
Cruise Charts • Maximum range is at L/Dmax or best glide speed • Maximum endurance is about 76% or best glide speed • Generally close to stall speed
Excessive Weight • Higher takeoff speed • Longer takeoff run • Reduced rate and angle of climb • Lower maximum altitude
Excessive Weight • Shorter range and endurance • Reduced cruise speed and maneuverability • Higher stall speed • Higher landing speed and longer landing roll
Forward CG Effects • Higher takeoff speed and ground roll • Reduced rate and angle of climb • Lower maximum altitude • Reduced maneuverability
Forward CG Effects • Higher stalling speed • Reduction in performance caused by increased tail-down loading • Reduced pitch authority
Beyond Aft CG Effects • Decreased stability and increased susceptibility to over control • Increased risk of stalls and spins of which recovery may be difficult or impossible
Weight Shift Computations Weight of Cargo Moved Distance CG moves Airplane weight = Distance Between Arm locations
Elt • Frequency 121.5 and 243.0 • Battery • 1 hour of cumulative use • One half the battery useful life • Test during 5 minutes after the hour
Diverting for Emergencies • Time is of the essence • Turn to new course as soon as possible • Use rule of thumb computations, estimates and shortcuts
Engine Temperature • Oil cools the internal portion of the engine • High temperature is often a sign of low oil level
Heating System • Heating in most aircraft is by exhaust manifold-type • Crack in the system can allow carbon monoxide into the cabin • If your aircraft backfires during run up, have it checked
Engine Failure(Takeoff) • Lower the nose and maintain a safe airspeed
Turbulence • Slow to maneuvering speed • Maintain a level attitude • Do not chase the pitot static instruments
Spatial Disorientation • Rely on instrument indications • Ignore body sensations
Emergency Descent • Reduce the throttle to idle • Roll into a bank angle of approximately 30-45 degrees • Set propeller to low pitch ( High RPM)
Emergency Descent • Extend landing gear and Flap as recommended by the manufacturer • Do not exceed VNE, VLE, VFE, or VA if turbulent
