Fundamentals Of Flight

Question 0

What are the 3 types of motion pertaining to flight?

Answer 0

Acceleration
Speed
Velocity

Question 1

What is motion?

Answer 1

The act or process of changing place or positions

Question 2

What is acceleration?

Answer 2

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

Question 3

What is speed?

Answer 3

Rate of movement in terms of distance measured in time

Question 4

What is velocity?

Answer 4

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

Question 5

What is newtons 1st law of motion?

Answer 5

(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

Question 6

What is newtons 2nd law?

Answer 6

(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

Question 7

Newtons 3rd law?

Answer 7

For every action there is an equal and opposite reaction

Question 8

Bernoullis principle?

Answer 8

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

Question 9

General lift of an airfoil is dependent on what?

Answer 9

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

Question 10

What causes a wavelike effect to the wing?

Answer 10

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

Question 11

How is lift accomplished?

Answer 11

The difference in airflow across the airfoil.

Question 12

What are the forces affecting flight?

Answer 12

Lift
Weight
Drag
Thrust

Question 13

What is lift?

Answer 13

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

Question 14

What is drag?

Answer 14

the force that tends to hold aircraft back

Question 15

What causes drag?

Answer 15

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

Question 16

What is thrust?

Answer 16

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

Question 17

What are the aircraft axis?

Answer 17

Longitudinal
Lateral
Vertical

Question 18

What is longitudinal axis?

Answer 18

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

Question 19

What is lateral axis?

Answer 19

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

Question 20

What is vertical axis?

Answer 20

Imaginary line from top to bottom (yaw)

Question 21

What are the movable surfaces on a fixed wing ac?

Answer 21

Ailerons (roll) aileROLLons

Elevators (pitch) up and down

Rudders (yaw)

Question 22

Non axis flight controls?

Answer 22

Flap: extra lift

Spoiler: spoils wing lift

Speed brakes: reduces speed by drag

Slats: lateral handling at low speeds

Question 23

What is angle of attack?

Answer 23

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

Question 24

What is autorotation?

Answer 24

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

Question 25

What are the basics of a hydraulic system?

Answer 25

Reservoir
Pump
Tubes
Selector valve
Actuating unit

Question 26

Basics of landing gear

Answer 26

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