49
detonation
uncontrolled, explosive ignition of the fuel-air mixture within the cylinder’s combustion chamber; lower fuel grade than recommended; engine operation at high manifold in conjunction with low rpm; high power settings with excessively lean mixture
50
preignition
the fuel-air mixture ignites prior to the engine’s normal ignition event; residual hot spot in combustion chamber; loss of power and high operating temperatures
51
spark plug fouling
low engine operating temperatures paired with too rich of a mixture
52
magnetos
provides electrical current to the spark plug so it can ignite the fuel and air mixture; electrical current completely independent from the aircrafts electrical system; operates whenever the crankshaft is rotating
53
fuel air mixture
ratio of the "weight" of the fuel to the "weight" of the air in the mixture to be burned
54
constant speed prop
controllable pitch prop whose pitch is automatically varied by the governor; once an rpm is selected the governor automatically adjusts the prop blade
55
parasite drag
drag caused by all of the aircrafts external components (besides wing)
56
induced drag
by product of lift (newtons 3rd law)
57
basic med limitations
no more than 6 occupants including the pilot, max cert takeoff weight no more than 6000, cannot carry more than 5 pax, operates VFR and IFR within the US, less than 18,000 ft, cannot go above 250 kts, cannot fly for comp or hire
58
static stability
initial tendency or direction of movement back to equilibrium
59
dynamic stability
initial tendency to return to equilibrium that the aircraft displays after being disturbed from its trimmed condition
60
common carriage
holding out to the public as willing to furnish transportation within the limits of its facilities to any person who wants it; four elements are holding out of a willingness to transport persons or property from place to place for compensation; 18-24 contracts
61
private carriage
carriage that does not involve holding out; sometimes called contract carriers; carriage for one or several selected customers generally on a long term basis
62
high pressure system
clockwise, outwards, downwards; higher pressure/density; descending air which favors dissipation of cloudiness, calm or light winds, and fewer clouds
63
low pressure system
counterclockwise, inwards, and rising; rising air in conductive to cloudiness, precipitation, poor visibility, gusty winds, and turbulence; trough may be violent weather area
64
cold front
separates an advancing mass of cold, dense, and stable air from an area of warm, lighter, and unstable air; cold, dense air moves along the surface and forces the less dense, warm air upward; movement usually eastward
65
stationary fronts
when opposing forces from two air masses are balanced, the front that separates them might remain stationary and influence local flying conditions for several days; weather usually a mixture of that found in both warm and cold fronts
66
frontal occlusion
fast moving cold front catches up to a slow moving warm front; difference in temperature within each moving frontal system strongly influences which type of front and weather are created
67
cold front occlusion
when a fast moving cold front is colder than the air ahead of the slow moving warm front; cold air replaces the cool air at the surface and forces the warm air aloft
68
warm front occlusion
when the fast moving cold front is warmer than the air ahead of the slow moving warm front; cold front rides over the warm front forcing the cold front aloft
69
p factor
when the downward moving propeller blade takes a bigger "bite" of air than the upward moving blade; happens at high aoa or taking off
70
gyroscopic precession
you apply a force to one point of the disc (prop), and the effect of that force (the resultant force) is felt 90 degrees in the direction of rotation of the disc; that forward-moving force, on the right side of the propeller, creates a yawing motion to the left
71
spiraling slip stream
happens when your prop is moving fast and your plane is moving slow; takeoff is the best example; air accelerated behind the prop (known as the slipstream) follows a corkscrew pattern. as it wraps itself around the fuselage of your plane, it hits the left side of your aircraft's tail, creating a yawing motion, and making the aircraft yaw left
72
strokes of an engine
suck, squeeze, bang, blow (intake, compression, power, exhaust)
73
intake stroke
engine mixes fuel and air in the intake manifold; as it mixes, the intake valve opens as your piston moves down, drawing the fuel-air mixture into the combustion chamber
74
compression stroke
the piston is forced up after the intake valve closes, compressing the fuel-air mixture before it is ignited
75
power stroke
only stroke that provides you with horsepower; before the piston reaches it's highest point (top-dead-center), your spark plugs send a current arching across their prongs, igniting the fuel-air mixture; as the fuel and air combust they expand, pushing down the piston; the directional motion of the piston moving down is converted to rotational motion as your piston turns the crankshaft, providing power
76
exhaust stroke
now that your engine has extracted the potential energy from the fuel-air mixture you sucked into the cylinders, it's time to set it up again; exhaust valve opens, and the piston moves up, pushing the exhaust gas out of the cylinder and into the exhaust system
77
wet lease
lessor provides aircraft and crew (not legal)
78
dry lease
lessee provides its own crew; permitted to operate under part 91, not required to comply with 121/135 operations
79
commercial pilots may not operate for comp or hire in these categories
restricted, limited, primary, experimental
80
cones
function well in bright light and are sensitive to colors
81
rods
react to low light but not colors
82
vestibular system
located in your inner ear consists of the vestibule and three semicircular canals; canals are oriented in 3 planes which enables them to sense yaw, pitch, and roll
83
induction icing
affects engine power and includes carb icing and air intake icing
84
structural icing
builds up any exposed surface of an aircraft causing loss of lift, an increase in weight, and control problems
85
types of structural icing
clear, rime, and mixed
86
rime ice
normally encountered in stratus clouds and results from instantaneous freezing of tiny water droplets striking the aircraft surface; opaque
87
clear ice
develops in areas of large water droplets that are found in cumulus clouds or in freezing rain beneath a warm front inversion; most serious of the various forms of ice because it has the fastest rate of accumulation, sticks to the aircraft, and is more difficult to remove
88
anti icing
prevents icing from forming
89
deicing
removes ice from the plane
