Question 10

76 sear regional jet similar to 737 amenities

Answer 10

Embraer E175 operated by regional horizon

Question 11

parts of the aircraft that allow the pilots to maneuver and control the aircraft during the flight

Answer 11

control surfaces

Question 12

What are the control surfaces

Answer 12

Rudder, Elevators, Ailerons

Question 13

What are the 4 forces that act on an airplane for flight that typically are in equilibrium

Answer 13

thrust, drag, lift, gravity

Question 14

engines push aircraft forward

Answer 14

thrust

Question 15

the act of the aircraft flying through dense air, pulls the aircraft backward

Answer 15

drag

Question 16

all the weight of the aircraft and what it carries, pulls the aircraft downward

Answer 16

gravity

Question 17

the wings push the aircraft upward

Answer 17

lift

Question 18

An airplane needs to have its weight distributed evenly to stay balanced and fly efficiently->stability

Answer 18

center of gravity

Question 19

Lift, low pressure over wing, high pressure below wing

Answer 19

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing.

Question 20

Wing shapes

Answer 20

• early straight (stable in slow flight-biplane)
• Super sonic jet swept wing(higher speeds and maneuverability-concorde jet)
• Airliner moderately swept wing design (blend of straight and swept for both stability and speed- 737 series)

Question 21

winglet types

Answer 21

split-scimitar-boeing- top and bottom winglets swept back to a point
Sharklets-airbus

Question 22

how are winglets aerodynamic?

Answer 22

reduce the air vortices at tips of wing to burn less fuel and fly more efficiently, reducing drag

Question 23

what are wing vortices

Answer 23

As a wing slices through the air, the tips of the wings create vortices that increase drag, decrease lift, and reduce fuel efficiency… this is why winglets are important

Question 24

How aircraft engines provide thrust

Answer 24

aircraft engines use turbofan jet engine to compress air from front (intake fan) and shoot it out the back, moving air over the wings to create lift

Question 25

engines create these 4 things

Answer 25

-massive thrust, hydraulic pressure, electricity, air conditioning.

Question 26

what are the components of a turbo-fan jet engine (6)

Answer 26

fan, compressor, combustion chamber, exhaust, turbine, bypass

Question 27

why to inform captain of icing

Answer 27

Icing decreases lift and increases drag by disturbing the air that is flowing around the aircraft. It also increases the overall aircraft weight, which means the aircraft must increase thrust to maintain control. *Icing on aircraft wings can severely disrupt the air flow, reduce lift, and introduce a hazard to the flight

Question 28

factors that can change one's exposure to cosmic radiation

Answer 28

duration of flight (longer = more) altitude(higher=more) latitude(farther from=more)

Question 29

characteristics of cosmic radiation

Answer 29

* Most radiation dissipates before reaching the earth’s surface. * Occurs when charged particles from space come in contact with earth. * It is filtered by the layers of earth’s atmosphere.

Question 30

Winds flowing in the same direction an aircraft is flying

Answer 30

Tail winds that reduce flight time

Question 31

Winds flowing in the opposite direction the aircraft is flying

Answer 31

Head winds, causes more fuel burn and longer flight

Question 32

Flight number and airline code alaska and horizon

Answer 32
