What is motion?

The act or process of changing place or positions

1

What are the 3 types of motion pertaining to flight?

Acceleration
Speed
Velocity

2

What is acceleration?

Rate of Change in the speed or velocity of matter with time

3

What is speed?

Rate of movement in terms of distance measured in time

4

What is velocity?

The quickness or speed of an object in a given time and direction

5

What is newtons 1st law of motion?

(Inertia) an object at rest will remain at rest, or an object in motion will continue in motion at the same speed and in same direction until acted on by an outside force

6

What is newtons 2nd law?

(Force) 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 and inversely proportional to the mass of the object being moved

7

Newtons 3rd law?

For every action there is an equal and opposite reaction

8

Bernoullis principle?

Fluid flowing through a tube reaches a narrowing the speed is increased and pressure is decreased.

9

General lift of an airfoil is dependent on what?

The airfoils ability to create circulation in the airstream and develop lifting pressure over the airfoil

10

What causes a wavelike effect to the wing?

The disruption in the flow of air due to the camber of the upper surface of the wing

11

How is lift accomplished?

The difference in airflow across the airfoil.

12

What are the forces affecting flight?

Lift
Weight
Drag
Thrust

13

What is lift?

The force that acts in the upward direction to support the aircraft in the air. This must be greater or equal to weight for flight

14

What is drag?

the force that tends to hold aircraft back

15

What causes drag?

Disruption of the air about the wings, fuselage, and all protruding objects

16

What is thrust?

The force created by the engines and acts in the fwd direction. Must be greater than or equal to drag

17

What are the aircraft axis?

Longitudinal
Lateral
Vertical

18

What is longitudinal axis?

An imaginary line running down the center of the aircraft (roll)

19

What is lateral axis?

Imaginary line running from wing tip to wing tip (pitch)

20

What is vertical axis?

Imaginary line from top to bottom (yaw)

21

What are the movable surfaces on a fixed wing ac?

Ailerons (roll) aileROLLons

Elevators (pitch) up and down

Rudders (yaw)

22

Non axis flight controls?

Flap: extra lift

Spoiler: spoils wing lift

Speed brakes: reduces speed by drag

Slats: lateral handling at low speeds

23

What is angle of attack?

Angle of the airfoil chord at which it meets the flow of air

24

What is autorotation?

A means of safely landing an aircraft without use of engine power. The use of the collective downward allows rotor to maintain rpm

25

What are the basics of a hydraulic system?

Reservoir
Pump
Tubes
Selector valve
Actuating unit

26

Basics of landing gear

Shock strut
Tires
Brakes
Retracting and extending landing gear
Side struts and supports
