Aviation Information

Question 1

Newton’s laws of Motion

Answer 1

3 total laws

1: Focuses on inertia
2: defines when an accelerated motion is applied to a force

3: the relationship of motion between any two objects

Question 2

Newton’s first law of motion

Answer 2

Law of Inertia

States that an object at rest will stay at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Question 3

Types of friction

Answer 3

4 types

1: sliding or kinetic friction
2: fluid friction
3: rolling friction
4: static friction

Question 4

Sliding or kinetic friction

Answer 4

Results when the surface Of one object slides along the surface of another object. This is commonly seen when pushing a solid object such as a plate or book along a tabletop

Question 5

Fluid friction

Answer 5

Is the resistance on an object when it is moved through either air gas or water liquid. This is witnessed when a fish moves through water a bird flies through air or an airplane Creech drag

Question 6

Rolling friction

Answer 6

Is similar to sliding friction except rolling friction occurs when an object rules and set of slides across the surface this is observed when a bowling ball rolls down an alley the ball once pushed moves at a particular Rate or velocity wall also resisting the movement due to qualities of the surface on which it is rolling

Question 7

Static friction

Answer 7

Is what keeps an object at rest when the object is acted upon by an external force. A trash can initially remains in place due to static friction when an attempt is made to drag it across a floor.

Question 8

Newton’s second law of motion

Answer 8

States that when a body is acted upon by a constant force, it’s resulting acceleration is inversely proportional to the mass of the body and directly proportional to the applied force.

Question 9

Newton’s third law of motion

Answer 9

If two objects interact, the force exerted by the first object on the second object is equal in magnitude and opposite in direction to the force exerted by the second object on the first object.

Question 10

Newton’s law of universal gravitation

Answer 10

A particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

Question 11

Bernoulli’s principal

Answer 11

With in a horizontal flow of fluid points of faster fluid speed will experience less pressure than periods of slower fluid speed

Question 12

Four forces of flight

Answer 12

Weight: the force of gravity pushing aircraft down

Lift: force required to raise aircraft

Thrust: force applied in order to move the aircraft forward

Drag: force that slows down the aircraft in preparation for landing

Question 13

EWCG

Answer 13

Empty weight center of gravity

Provided by AC manufacturer along with a weight limit, which is specific to each AC

Question 14

MEW

Answer 14

Manufacturers Empty Weight

Total weight of the aircraft as it was built. Includes systems and components required for the AC to operate. Does not include weight of baggage, passengers, or either usable or unusable fluids or fuel

Question 15

OEW

Answer 15

Operating empty weight

This is the MEW plus the weight of the crew, fluids, unusable fuel, and the equipment required for flight. Does not include baggage, passengers or useable fuel.

Question 16

AUW/AGW

Answer 16

All-up weight or Aircraft gross weight

Total AC weight at any given moment during a flight. The AUW decreases as fuel and fluids are consumed during the operation of the flight.

Question 17

MLW

Answer 17

Maximum landing weight

An AC weight limit for landing. Exceeding this weight increases stress in the landing gear and may affect the distance required for a safe landing

Question 18

MZFW

Answer 18

Maximum zero fuel weight

Permissible weight of an aircraft with its contents and includes unusable fuel. The total MZFW excludes the weight of usable fuel on board and any consumable fluids.

Question 19

MTOW

Answer 19

Maximum take off weight

Is an aircrafts weight limit for takeoff. Exceeding this limit increases the power required for takeoff, lengthens the runway distance needed for a successful lift off and places excess stress on the AC structure

Question 20

MRW

Answer 20

Maximum ramp weight

Is the weight limit for an AC to taxi or be towed on the ground

Question 21

Flight envelope

Answer 21

Encompasses the limits of speed, altitude and angle of attack required by any aircraft to maintain stable flight.

Question 22

AOA

Answer 22

Angle of attack

Angle between the direction of the airflow against the wing and the Chord

Question 23

Chord

Answer 23

Imaginary reference line that extends from the leading edge to the trailing edge of the wing.

Question 24

Ailerons

Answer 24

Located from the midpoint of the trailing edge of the wing to the wings tip.

Question 25

Flaps

Answer 25

Are located from the fuselage to about midpoint of the wing

Question 26

Spoilers

Answer 26

Extend upward from wing to help reduce airspeed

Question 27

Parasite drag

Answer 27

Any “parasite” on the structure of the aircraft I.e. low air pressure in tires, skin friction, or anything that increases turbulence on AC.

Question 28

Skin friction

Answer 28

Any rough spot in the skin of AC structure.

Question 29

Profile drag

Answer 29

Produced mainly by the shape of the AC. Size is directly proportional to increase of drag

Question 30

Induced Drag

Answer 30

Is when, at the back of the wing, air flowing rapidly across the top means air flowing more slowly underneath, creating a vortex.

Question 31

Roll

Answer 31

Along AC longitudinal axis is controlled by adjustment of the ailerons

Question 32

Pitch

Answer 32

Lateral angle of ascent or descent controlled by elevators

Question 33

Yaw

Answer 33

Movement from side to side created by the tail rudder.

Question 34

Pressure altimeter

Answer 34

Automatically set for 29.92 inHg
