Fundamentals of Flight

Question 1

Acceleration

Answer 1

Rate of change of the speed and or velocity of matter with time

Question 2

Speed

Answer 2

Rate of movement in terms of distance measured in an allotted amount of time

Question 3

Velocity

Answer 3

Quickness or speed of an object in a given time and direction

Question 4

Newton’s First Law

Answer 4

An object at rest will remain at rest, or an object in motion will continue in motion at the speed and in the same direction, until acted upon by an outside force

Question 5

Newton’s Second Law

Answer 5

If an object moving with uniform speed is acted upon by an external force, the change of motion, or acceleration, will be directly proportional to the amount of force

Question 6

Newton’s Third Law

Answer 6

For every action there is an equal and oppsite reaction

Question 7

Bernoulli’s Principle

Answer 7

Fluid passing through the constriction is increased and it’s pressure decreased

Question 8

Lift

Answer 8

Upward direction

Question 9

Weight

Answer 9

Gravity acting downward

Question 10

Drag

Answer 10

Holds an aircraft back

Question 11

Thrust

Answer 11

Forward direction

Question 12

Longitudinal axis

Answer 12

Imaginary line running down the center of the aircraft between the nose and tail

Question 13

Lateral axis

Answer 13

Imaginary line running parallel to the wings

Question 14

Vertical axis

Answer 14

Imaginary line running from the top to the bottom of the aircraft

Question 15

Ailerons (roll)

Answer 15

Longitudinal axis

Question 16

Elevators (pitch)

Answer 16

Lateral axis

Question 17

Rudder (yaw)

Answer 17

Vertical axis

Question 18

The cyclic stick (roll/pitch)

Answer 18

Tilts the plane of the rotor blades forward, aft or sideways giving the helicopter its directional motion

Question 19

Tail rotor (yaw)

Answer 19

Increases or decreases the amount of horizontal thrust the tail rotor produces

Question 20

Collective

Answer 20

Lift may be changed by collectively increasing the angle of attack or pitch of the rotor blades

Question 21

Angle of Attack

Answer 21

The angle at which the airfoil or fuselage meets a flow of air

Question 22

Basic aircraft hydraulic system

Answer 22

Reservoir to hold hydraulic fluid, pump to provide a flow of fluid, tubing to transmit the fluid, selector valve to direct the flow of fluid, an actuating unit to convert the fluid pressure into useful work
