section a
Fuselage
houses the cabin and cockpit, controls for airplane, cargo, and occupants
also attaches other airplane components
wing
air flows around the wings of an airplane and generates lift.
attached to the top, middle or lower portion of the fuselage
monoplanes
airplanes with one set of wings
biplanes
two sets of wings
two types of control surfaces attached to the rear of the wing or trailing edges
ailerons and flaps
ailerons
connected to the outside portion of the wing, connected to the cockpit control,
ailerons move in opposite directions to roll the plane in and out of turns.
flaps
inner portion of the wing
extend downward to increase wing’s lift for takeoff and landing
empennage
consists of vertical stabilizer, horizontal stabilizer, and elevator
help maintain straight path through the air
rudder
attached to the back of the vertical stabilizer
for moving the plane left or right
operated by pedals
combination of ailerons and rudder to turn plane
elevator
attached to horizontal stabilizer
for increasing or decreasing altitude
stabilator
pivots up and down, replacement for elevator
trim tab
usually located on elevator,
help minimize workload on flight controls
anti-servo tab
provides a control feel, also functions as a trim tab
landing gear
supports plane while on ground, normally three wheels
conventional landing gear
tailwheel planes, two wheels in front one on tail
nose wheel/ tricycle gear
one wheel at the nose, two at the back
steer airplane using rudder pedal
fixed gear
always remains extended, low cost
retractable gear
stows the landing gear inside the airplane
for high performance aircraft
