107 General Aviation Fundamentals Flashcards
Define Newton’s First Law of Motion
An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.
Define Newton’s Second Law of Motion
An object pushed with 10 pounds of force will move faster than with 5 pounds
Define Newton’s Third Law of Motion
For every action, there is an equal and opposite reaction.
Describe Inertia
an objects willingness to remain at rest or in motion
Describe Acceleration
The rate of change of the speed and/or velocity of matter with time
Describe Speed
The rate of movement or motion in a given amount of time.
Describe Velocity
rate of movement in a given amount of time AND direction
Define Bernoulli’s Principle
When a liquid flowing through a tube reaches a constriction point, the speed is increased and its pressure is decreased.
Describe Lift
The force that acts in an upward direction
Describe Weight
The force of gravity acting downward
Describe Drag
The resistance to motion
Describe Thrust
Force developed by the engines acting in a forward direction
Describe the Longitudinal Axis
Line down the center from the nose to the tail of an aircraft, roll
Describe the Lateral Axis
Line parallel to wings, pitch
describe the Vertical Axis
Line from top to bottom, yaw
State the three primary movements of aircraft about the axes
Pitch, roll, yaw
Identify and state the purpose of the primary flight controls for Fixed-Wing Aircraft
Yoke, throttle, rudder pedals, Aileron, Elevation
Identify and state the purpose of the primary flight controls for Rotary Wing Aircraft
Collective, cyclic, tail rotor pedals
State the purpose of Flap
Gives aircraft extra lift
State the purpose of Spoiler
Used to decrease wing lift
State the purpose of Speed Brakes
Used to reduce the speed of aircraft
State the purpose of Slats
Attached to leading edge of wing for boundary layer control, increase/decrease angle of attack
State the purpose of the Horizontal Stabilizer
Stability of vertical and longitudinal axis, directional stability
State the purpose of the Vertical Stabilizer (what planes have on the tail)
Stability of longitudinal axis, directional stability
State the purpose of the Tail Rotor
Counteracts torque action of main rotor by producing thrust in opposite direction
State the purpose of the Trim Tabs
Located on the back of an elevator to keep the aircraft level
Explain the term Angle of Attack
The angle at which the airfoil encounters the air
Explain the term Autorotation
Use of reverse airflow to safely land helicopter, trading Nr for Np.
State the components of a basic hydraulic system
PARTS: Pump, Actuator, Reservoir, Tubing, Selector Valve
Describe and explain the main components of landing gear
Shock struts, tires, brakes, retracting and extending mechanism, side struts and supports,
