Mechanics

Question 1

who is daniel bernoulli

Answer 1

developed the laws explaining how wings produce lift

Question 2

explain the bernoulli principle

Answer 2

velocity in = pressure decreases = lift
higher pressure on the bottom causes wing to rise

Question 3

what meets relative wind first (usually rounded)

Answer 3

leading edge

Question 4

last portion of airfoil to contact relative wind

Answer 4

trailing edge

Question 5

curve away from center line (chord)

Answer 5

camber

Question 6

imaginary line connecting the leading edge to the trailing edge

Answer 6

chord line (cuts airflow in half)

Question 7

what is the angle of attack

Answer 7

the angle of airfoil to the relative wind
angle between wind and chord line

Question 8

what are the four forces of flight

Answer 8

lift, thrust, weight, and drag

Question 9

define thrust

Answer 9

power put into aircraft

Question 10

define weight

Answer 10

gravity pulling aircraft down

Question 11

define drag

Answer 11

friction- stuff that pulls aircraft back

Question 12

what does it mean to be in balance

Answer 12

straight and level
lift=weight
thrust=drag

Question 13

what are the axes of an aircraft

Answer 13

longitudinal, lateral,
vertical

Question 14

what is longitudinal axis

Answer 14

produces roll(movement left and right)
ailerons

Question 15

what is vertical axis

Answer 15

yaw (direction facing)
left & right rudder

Question 16

what is the lateral axis

Answer 16

pitch up and down(clime and descend)
elevator

Question 17

define control instruments

Answer 17

current state of aircraft power setting and attitude- bare necessity is the engine operation how it should

Question 18

define performance instruments

Answer 18

how the aircraft responds to our commands- backup information

Question 19

definition navigational instruments

Answer 19

aircraft location and communication

Question 20

types of engines

Answer 20

lots of turbine or reciprocating

Question 21

types of aircraft systems

Answer 21

fuel- gas from tank to engine
hydraulic- fluids
electrical- most important requirement for all other to work

Question 22

define navigation

Answer 22

the science of getting things from place to place

Question 23

define a great circle

Answer 23

any circle passing thought earths center

Question 24

define a small circle

Answer 24

any circle not passing through earths center

Question 25

a system constructed as a sphere to match the surface of the earth h

Answer 25

global coordinate system

Question 26

define latitude

Answer 26

ladder- parallel and extended north and south of equator

Question 27

define longitude

Answer 27

run both and south from the poles starting in prime meridian

Question 28

what is dead reckoning

Answer 28

planing what you will see and the seed and where you are going

Question 29

what is pilotage

Answer 29

having no plans just using charts a type of navigation
