Fundentals Of Flight / NAMP / AIMD / NALCOMIS / NATOPS Flashcards
Explain acceleration.
The rate of change of the speed and/or velocity of matter with time.
Explain speed.
The rate of movement in terms of distance measured in an allotted amount of time.
Explain velocity.
The quickness or speed of an object in a given time and direction.
Explain Newton’s 1st Law.
Inertia - an object at rest will stay 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 source.
Explain Newton’s 2nd Law.
Force - if an object with uniform speed is acted upon by an external 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 being moved.
Explain Newton’s 3rd Law.
Action & Reaction - states that for every action there is an equal and opposite reaction.
Explain Bernoulli’s principle.
When a fluid flowing through a tube reaches a construction or narrowing of the tube, the speed of the fluid passing through the construction is increased and its pressure decreased.
Explain Lift.
The force that acts, in an upward direction, to support the aircraft in the air.
Explain Weight.
The force of gravity acting downward on the aircraft and everything on the aircraft.
Explain Drag.
The force that tends to hold the aircraft back.
Explain Thrust.
The force developed by the aircrafts engine.
What are the basic components of the aircraft?
Ailerons, Elevators, Rudder
What do the Ailerons control?
The Longitudinal axis (Roll)
What do the Elevators control?
The Vertical axis (YAW)
What does the Rudder control?
The Lateral axis (Pitch)
What type of aircraft had a cyclic stick?
Rotary wing aircraft (Helicopters)
What does the cyclic stick control?
Roll/Pitch
What type of aircraft had a collective?
Helicopter
What is a Flap?
(Leading/Trailing edge) Creates extra lift by lengthening the top section of the wing.
What is a spoiler used for?
Used to decrease or spoil wing lift by destroying the smooth flow of air over the wing surface.
What are Speed Breaks?
Hinged or moveable control surfaces used for reducing the speed of the aircraft.
What are Slats?
Moveable control surfaces attached to the leading edge of the wing.
Explain Angle of Attack.
The angle at which the airfoil or fuselage meets a flow of air.
Explain the purpose of Auto Rotation.
A method of allowing a helicopter to land safely from altitude without using engine power.
