|
Bernoulli's principle |
principle of lift low pressure; accelerated fluid has less pressure than unaccelerated fluid |
|
|
Angle of attack |
creates more or less lift angle between your wind and wing |
|
|
angle of incidence |
angle at which the wings are attached to the fuselage |
|
|
Lift |
use to overcome weight, low pressure created by the curvature of the top of the wing |
|
|
drag |
the force that is |
|
|
thrust |
from engine and propel set you in motion and overcome drag |
|
|
camber |
amount of curve at the top of the wing |
|
|
center of gravity |
balance point of an object |
|
|
center of lift |
the balance point of the wing |
|
|
fuselage |
where the cargo &/or passengers go the body of the aircraft |
|
|
empennage |
the tail section of the aircraft |
|
|
cowl |
like a hood the cover to the engine serves 2 purposes - reduces drag and covers the engine & cools the engine |
|
|
nacelle
|
the whole engine package of an aircraft
engine and cowl make this up |
|
|
spinner |
the cone shaped part, in the center of the propeller
placed in for aerodynamics |
|
|
elevator |
control surface - horizontal control surface of the plane, it controls pitch |
|
|
horizontal stabilizer |
it does not move; it stabilizes pitch; located in the tail - next to elevator |
|
|
vertical stabilizer |
the vertical stabilizer, next to elevator, controls yaw - know left and right |
|
|
rudder |
directs the nose of the plane left and right; controls yaw |
|
|
flaps |
the wing root, they move both together. they increase drag by increase difference and increase lift help control speed |
|
|
aileron |
wing tip that control bank. control surface |
|
|
trim tabs |
on the trailing edge of the control surface. cruise control for altitude enable you to take your hands off the controls, even with weight shift |
|
|
wing strut |
attaches the wing to the fuselage for additional structural support |
|
|
main gear |
2 located where the brakes are weight is supported by this |
|
|
nose gear |
doesn't have breaks more to keep the nose off the ground it steers located in the ground |
|
|
tricycle gear |
main gear in the back, nose gear in the front |
|
|
conventional gear |
official name to tail wheel used to be called tail dagger |
|
|
rotate |
lifting the nose for take off so that the angle can lift the plane up |
|
|
stall |
when your wing gets too high of angle off attack and the wind is tumbling off the top - no lift produced |
|
|
down wash |
a by-product of lift air comig off back of wing at |
|
|
control yoke |
steering wheel controls two axis - bank and pitch |
|
|
rudder pedals |
controls yaw has breaks on them |
|
|
differential braking |
individual breaks for left and right mean gear |
|
|
take off roll |
the distance required to take off |
|
|
cross wind |
wind prependicular to the runway |
|
|
landing roll |
distance required to land |
|
|
level off |
when you stop changing altitude |
|
|
landing flare |
the orientation of your aircraft when you're landing, brinign your nose up for landing |
|
|
GPS |
global positioning satellite use of satellites to triangulate your position |
|
|
ATC |
air traffic control |
|
|
tower |
ATC for aircraft taking off and landing |
|
|
Ground |
ATC air craft on the ground |
|
|
Center |
ATC en route aircraft aircraft goes through multiple airspaces |
|
|
approach control |
ATC for aircraft coming into an area |
|
|
departure control |
ATC for aircraft departing |
|
|
traffic pattern |
standardized pattern for take-off and landing |
|
|
pattern altitude |
1,000 feet above ground |
|
|
rate of climb |
how fast you're changing altitude rated in feet per second |
|
|
stratus clouds |
flate, thin layer clouds do not produce thunderstorms, lightning, and tornados |
|
|
convection currents |
vertical air movement not stable |
|
|
turbulence |
up drafts and down drafts |
|
|
chop |
very small up drafts and down drafts |
|
|
jet wake/wake turbulance |
horizontal vortex coming from the tip of the wing coz of low pressure |
|
|
glide ratio |
ratio between distance above earth (altitude) |
|
|
aspect ratio |
the ratio between wing span and cord line it creates better glide ratio |
