107 General Aviation Fundamentals Flashcards
Define Newton’s First Law of Motion
An object at rest will remain at rest, or an object in motion will continue in motion at the same speed and in the same direction, until acted upon by an outside force.
Define Newton’s Second Law of Motion
If an object moving with uniform speed is acted upon by an outside force, the change of motion, or acceleration, will be directly proportional to the amount of force and inversely proportional to the mass of the object.
Define Newton’s Third Law of Motion
For every action, there is an equal and opposite reaction.
Describe Inertia
the willingness of an object to remain at rest or continue in motion unless acted upon by an outside force
Describe Acceleration
The rate of change of the speed and/or velocity of matter with time
Describe Speed
The rate of movement or motion in a given amount of time. (i.e. 60mph)
Describe Velocity
The speed of an object over a given time AND direction (i.e. 200mph due north)
Define Bernoulli’s Principle
When a liquid flowing through a tube reaches a constriction or narrowing of the tube, the speed of the fluid passing through the construction is increased and its pressure is decreased. (when velocity is increased, pressure is decreased.)
Discuss Wind Warnings and their effect on naval aviation
- Small Craft-harbor and inland waters (18-33 knots)
- Gale- same plus ocean areas, airfields & installations (34-47 knots)
- Storm- same (48+ knots)
Discuss Hurricane/Typhoon conditions and their effect on naval aviation
Destructive winds of 80 knots or greater are occurring or anticipated within: I. 12 hrs II. 24 hrs III. 48 hrs IV. 72 hrs V. 96 hrs
Discuss T-Storm/Tornado conditions and their effect on naval aviation
T2 - (watch) 25 mi or 6 hrs
T1 - (warning) 10 mi or 1 hr
Discuss Thunderstorm Watch/Warning
Watch - possible
Warning - storm sighted
Discuss Tornado Watch/Warning
Watch-conditions favorable for tornado
Warning-likely a tornado exists.
Discuss Winter Storm Advisory
Possible snow or other winter conditions which could pose a threat to specific personnel, but not a large enough hazard to alert the general public
Discuss Winter Storm Watch/Warning
Watch-occurrence, location, time uncertain
Warning-imminent or occurring
Discuss Wind Shear
Rapidly changing wind speed and direction
Discuss Micro burst
Can cause aircraft to suddenly speed or slow, causing drop onto runway
Discuss SIGMET
Significant Meteorological Advisory:
Convective - thunderstorms
Non-Convective - turbulence, ice
Describe Lift
The force that pushes up on the airfoil
Describe Weight
The force that interacts with gravity to pull the aircraft down
Describe Drag
The resistance to motion
Describe Thrust
Force that pushes the aircraft along
Describe the Longitudinal Axis
The imaginary reference line that runs from the nose to the tail of an aircraft
Describe the Lateral Axis
The imaginary reference line that runs from one side to the concurrent other side of an aircraft
describe the Vertical Axis
The imaginary reference line that runs straight up and down through the top and bottom of an aircraft
State the three primary movements of aircraft about the axes
Roll, pitch and yaw
Identify and state the purpose of the primary flight controls for Fixed-Wing Aircraft
Yoke, throttle, rudder pedals, and some planes have flap levers, spoiler levers, trim controls and a tiller)
Identify and state the purpose of the primary flight controls for Rotary Wing Aircraft
Collective, cyclic, tail rotor pedals
State the purpose of Flaps
Gives aircraft extra lift
State the purpose of Spoilers
Used to decrease wing lift
