Check Ride Prep F: Performance and Limitations Flashcards
Airfoil
Surface capable of producing lift
Relative Wind
wind wrt airfoil
Angle of Attack
angle btwn chordline and relative wind
Bernoulli’s Principal
As velocity of a fluid increases, pressure decreases
Left Turn Tendencies
-Most Prominent @:
-High Power
-High AOA
-Low Airspeed
1.Torque:
-newton’s equal and opposite rx
-only rolling
2.Slipstream:
-vorticies of air moves around plane, hitting tail, yawing left
3.P-factor:
-propellor
-down faster than up
4.Gyroscopic Effect:
-propellor
-a force felt on a spinning disk is felt 90 degrees in the direction of rotation
Load Factor
Actual load supported by wings divided by the total weight of the airplane
-effect of gravity on the plane in a bank
- 60 degrees = 2 G’s
Why is it dangerous?
- overloading the plane is not good
-increase stall speed
Va
Maneuvering Speed:
-@ or below we will stall before structural damage occurs, across only 1 axis of motion
-speed is based on weight
Stall
Loss of lift due to excessive AOA
Spin
P Power- lowers torque
A Ailerons- Neutral
R Rudder- full opp. rudder
E Elevator- Forward
Ground Effect
Condition of improved performance when operating near to the ground.
-airflow over the wing is restricted by the ground
