Aviation

Question 1

Fuselage

Answer 1

Body of airplane

Question 2

How many wings? Typical

Answer 2

Counted in sets , most are monoplanes

Question 3

Description of wings

Answer 3

Serve as main lifting mechanism supporting airplane in flight. Considered an airfoil- aircraft part or surface that controls lift, direction, stability, thrust, or propolsion

Question 4

Attachment of wings to fuselage (top middle or bottom)

Answer 4

High wing, mid wing, low wing

Question 5

Wing bracing and support

Answer 5

Cantilever: requires no external bracing, gets support from internal items / semi-cantilever : both internal and external support from struts attached to fusalage

Question 6

Ailerons

Answer 6

Middle of wing out to wing tip, move in opposite directions to create aerodynamic forced that cause airplane to roll

Question 7

Flaps

Answer 7

Flaps- attached to trailing edge of wing, increased both lift and drag when extended move downward together to increase lift of the wing for takeoffs and landings

Question 8

Airfoil

Answer 8

A part of aircraft (wing, rudders propeller blade) helping with lift and thrust

Question 9

Leading edge of airfoil/trailing edge

Answer 9

Leading edge: thicker attached to fuselage
Trailing edge: end of airfoil, thinner

Question 10

Camber

Answer 10

Curved surface

Question 11

Bernoullis Principle

Answer 11

Explanation for airfoil generating lift - top of surface of wing has greater camber than bottom surface of wing
AND air flows faster in too than underneath (less pressure above than underneath) difference in air pressure causes lift

Question 12

Actual lift theory

Answer 12

Newtons laws

Question 13

Chord

Answer 13

Distance from leading edge to training edge , cuts airfoil into upper and lower surface

Question 14

Dihedral angle

Answer 14

Angle of wings

Question 15

Swept wing

Answer 15

Most common design for modern / high speed airplanes

Question 16

Propeller airplanes gain thrust how

Answer 16

Corkscrew action of propellers, blades rotating very fast infront of engine, pushing air backwards, plane moves forward

Question 17

Jet engine

Answer 17

Forced incoming air into tube or cylinder, compressed and mixed with fuel then burned and pushed out exhaust

Question 18

Elevator

Answer 18

Movable control- moved nose or airplane (up or down)

Question 19

Rudder

Answer 19

Movable control attached to vertical stabilizer , used to move airplane nose left and right

Question 20

Trim tabs

Answer 20

Small movable segments on rudder and elevators and ailerons, controlled by pilot, reduce control pressures and pilot workload

Question 21

4 flight forces

Answer 21

Lift: pushes aircraft up
Gravity: weight, pulls aircraft down
Thrust: pushes aircraft forward
Drag: slows aircraft, pushing back as it pushes forward

Question 22

Flight attitude

Answer 22

Position in flight , changing on axes,

Question 23

Roll is controlled by and what axis is it on

Answer 23

Ailerons , longitudinal (provided lateral stability), initiate turns

Question 24

Pitch is controlled by and what axis is it in

Answer 24

Elevators, lateral (provides opposite type of stability- longitudinal), affects pitch,

Question 25

Yaw is controlled by and what axis is it on

Answer 25

Rudders, vertical , provided directional stability,

Question 26

Atmosphere is composed of

Answer 26

78% nitrogen, 21% o2

Question 27

Heavier items are closer or farther to earth

Answer 27

Closer. Lighter elements are further

Question 28

Angle of attack

Answer 28

Angle between horizontal and chord line of airfoil

Question 29

Secondary flight controls

Answer 29

Flaps, leading edge devices, spoilers, trim

Question 30

spoilers

Answer 30

Used for descent destroys lift

Question 31

Trim tabs

Answer 31

Used to relieve pilot of constant pressure of flight controls attached to trailing edge of elevator

Question 32

Altimeter

Answer 32

Measures height above a particular air pressure level

Question 33

Vertical Speed Indicstor

Answer 33

Indicated whether plane is climbing descending or in level flight

Question 34

Airspeed indicator

Answer 34

Shows difference between pitot pressure and static pressure, un disturbed atmospheric pressure at level flight

Question 35

4 types of air speed ICE T

Answer 35

Indicated , calibrated, equivalent, true

Question 36

Inclometer

Answer 36

Shows airplane yaw

Question 37

Artificial horizon

Answer 37

Attitude indicator, displays picture of airplane. Horizon bar = true horizon.

Question 38

For instrument comprehension

Answer 38

Go to compass heading first and eliminate any answer choices that aren’t heading in the right direction, THEN look at artificial horizon

Question 39

Helicopter lift

Answer 39

Most occurs at wing tips, so rotor blades are made with a twist do angle of attack decreased as distance from rotor hub increases

Question 40

Helicopter controls

Answer 40

Cyclic- longitudinal and lateral movement Collective- controls pitch and engine torque Directional control system: pilot controls tail rotor torque
