POF Flashcards
aircraft parts and structures
fuselage / powerplant / wings / empennage / landing gear
any device which has been designed for flight
aircraft
a category of aircraft which is characterized by the use of both fixed wings and an engine
airplane
aircraft certification - categories
normal / utility / acrobatic / commuter / transport
pilot certification - category: airplane - classes
single engine land / multi engine land / single engine sea / multi engine sea
body or shell that holds passengers and cargo
fuselage
types of fuselages
truss / monocoque / semi monocoque
steel trusses welded together to form a frame
truss-type
still has a frame but their primary structure consists of an exterior surface
monocoque
features a cross section frame that’s joined together with stringers
semi monocoque
produces thrust to propel an aircraft
powerplant
basic parts of a powerplant
cowling / propeller / engine / firewall (attachment point)
part of an aircraft designed to produce lift
wings
wing planforms
elliptical / rectangular / tapered / sweptback / delta
by number of wings
monoplane / biplane / sesquiplane
wing position/placement
high wing / mid wing / low wing
tail of the plane
empennage
parts of a vertical stabilizer
rudder
parts of a horizontal stabilizer
elevator / trim tabs
reduces the effort which needs to be applied by the pilot onto the controls
trim tabs
principal support of the airplane when parked, taxiing, taking off, or landing
landing gear
types of landing gear
conventional / tricycle type / floats / skids / skis
first law of motion
inertia
second law of motion
F = ma
third law of motion
action - reaction
four forces acting on an airplane
lift / weight / thrust / drag
produced due to pressure differential
lift
bernoulli’s principle
high velocity, low pressure
part of the wings that interact with the air to create lift
airfoil
angle at which the chord of an aircraft’s wing meets the relative wind
angle of attack
angle between the aircrafts’s longitudinal axis and the chord of the wing
angle of incidence
aspect ratio formula
AR = b/c || b = span, c = wing area
pressure distribution in an airfoil
higher AOA, forward CP || lower AOA, aft CP
types of flaps
plain / split / slotted / fowler / slotted fowler
made up of the combined load of the airplane and its fuel, crew, passengers, and cargo which are pulled downward by gravity
weight
it opposes lift and acts vertically downward through the airplane’s center of gravity
weight
force that propels the airplane forward
thrust
retarding force that is caused by disruptions of airflow by the wings, fuselage, and other protruding objects
drag
drag generated by the aircraft due to its shape and air flowing around it
form drag
