What causes Limit Load Factor to be Exceeded
Level altitude Turns increase load factor exponentially.
Vertical gusts can increase angle of attack to resulting in increased load factor
Speed determines the amount of excess load that can be imposed upon the wing.
What is the load factor range for Normal, Utility, and Aerobatic
Load Factor range for Normal category is (3.8) - (-1.52)
Load Factor range for Utility category is (4.4) - (-1.76)
Load Factor range for Aerobatic category is (6.0) - (-3.0)
Increased load factor and stall relation
Load factor increases weight which increases stalling speed. Load factor increases as bank increases, and wings stall because you increase your Weight which means your aircraft is producing less lift with the increased weight, increasing stall speed.
Maneuvering speed defined
Maximum speed which the limit load factor can be imposed without causing structural damage
Maneuvering speed and Weight relation
Maneuvering speed increases with increase in weight. The described maneuvering speed is set to Max Gross Weight. You must calculate Va for your weight of the aircraft before taking off, so if you reach limit load factor you stall before you break.
Loss of control inflight (LOC-I) definition
Defined as the deviation of the aircraft from the intended flight path
Spin Defined
Controlled or Uncontrolled maneuver in which the aircraft descends in a spinning path, caused by aggravated stalls.
Spins Cause
Exceeding critical angle of attack while applying excessive or insufficient rudder/aileron
When are spins most likely to occur
Engine failure during takeoff climb out
Crossed-control turn from base to final
Engine failure on approach to landing
Go around with full nose-up trim
Go-around with improper flap retraction
How do you recover from a spin
Throttle Idle, Ailerons Neutral, Rudder opposite of spin, then Stall recovery
Adverse Yaw cause
In a roll one aileron is deflected downward and the other is deflected upward, the aileron that is deflected downward produces more lift and more drag causing a yaw opposite to your turn
What is Gross weight
The maximum allowable weight of both the airplane and its contents.
What is useful load
Weight of the pilot, copilot, passengers, baggage, usable fuel and drainable oil
What flight characteristics will be affected when aircraft is overloaded
Higher Takeoff Speed
Longer Takeoff Roll
Reduced rate of climb
Lower maximum altitude
Shorter range
Reduced cruising speed
Reduced maneuverability
Higher Stalling Speed
Higher Landing Roll
Longer Landing roll
Excessive weight on nosewheel
What affects does a forward CG have
Increased Stall Speed (Higher AoA to remain level)
Decreased Cruise Speed (More drag at higher AoA)
Increased Lateral Stability (More leverage)
What affects does a aft CG have
Decreased stall speed (Lower AoA to remain level)
Increased Cruise speed (Lower AoA)
Less Stable (Less leverage)
Poor Stall/Spin recovery (due to less stability)
What are the weights to Gasoline, Oil, and Water
Gas 6lbs
Oil 7.5lbs
Water 8.35lbs
Is it okay having a change CG not logged
No, its a requirement for an A&P to annotate and log any change of the CG
What are the main elements of aircraft performance
Takeoff and Landing distance
Rate of climb
Ceiling
Payload
Range
Speed
Fuel Economy
Maneuverability
Stability
What factors effect an aircraft on takeoff and landing
Air Density
Surface Wind
Runway surface
Upslope or Downslope runway
Weight
How does weight affect takeoff and landing performance?
higher takeoff speed, Slow acceleration, Increased drag and friction, increased landing speed, increased ground roll, decreases climb rate, and longer takeoff roll
Effects of increased density altitude
increased landing roll, increased TAS on approach/landing, reduced rate of climb, increased takeoff distance,
What does air density have a direct relation too
lift produced, propeller efficiency, drag, and engine performance
What affects air density
altitude, temperature, and humidity
