16
Q

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

A

gravity

17
Q

the wings push the aircraft upward

A

lift

18
Q

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

A

center of gravity

19
Q

Lift, low pressure over wing, high pressure below wing

A

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.

20
Q

Wing shapes

A
  • 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)
21
Q

winglet types

A

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

22
Q

how are winglets aerodynamic?

A

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

23
Q

what are wing vortices

A

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

24
Q

How aircraft engines provide thrust

A

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

25
Q

engines create these 4 things

A

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

26
Q

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

A

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

27
Q

why to inform captain of icing

A

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

28
Q

factors that can change one’s exposure to cosmic radiation

A

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

29
Q

characteristics of cosmic radiation

A
  • 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.
30
Q

Winds flowing in the same direction an aircraft is flying

A

Tail winds that reduce flight time

31
Q

Winds flowing in the opposite direction the aircraft is flying

A

Head winds, causes more fuel burn and longer flight

32
Q

Flight number and airline code alaska and horizon

A

AS 1-1999 9000-9999

Qx 2000-2999
