AIMD, FLIGHT, NAMP & NALCOMIS Flashcards
Explain Acceleration
Change in speed over time
Explain Velocity
Speed of an object in a given time and direction
Explain Speed
Distance measured over time
State Newton’s First Law
An object at rest will remain at rest, or an object in motion will remain in motion unless acted upon by an external force.
State Newton’s Second Law
If an object in motion at uniform speed is acted upon by an external force, the acceleration/deceleration of the object will be directly proportional to the amount of force and inversely proportional to the mass of the object.
State Newton’s Third Law
For every action there is an equal and opposite reaction
Explain Bernoulli’s Principle
When a fluid flowing in a tube reaches a constriction, the speed of the fluid will increase and the pressure will decrease.
Explain Lift
The force that acts in an upward direction to support an aircraft.
Explain Weight
The force of gravity acting downward on the aircraft.
Explain Drag
The force that tends to hold an aircraft back.
Explain Thrust
Force developed by the aircraft’s engines.
What are the basic components (control surfaces) of an aircraft?
Ailerons, Elevators and Rudders
What do Ailerons control?
Longitudinal Rotation (Roll)
What do Elevators control?
Lateral Rotation (Pitch)
What do rudders control?
Vertical Rotation (Yaw)
What type of aircraft has a cyclic stick?
Helicopter/ Rotary Wing
What does the cyclic stick control?
Pitch and Roll
What type of aircraft has a collective?
Helicopter
What is a flap?
Creates extra lift by lengthening the top edge of the wing
What is a spoiler?
Decreases (“spoils”) smooth flow over the wing to improve low-speed handling
What is speed/ air brake?
Reduces the airspeed of the aircraft
What are slats?
Control surfaces attached to the leading edge of the wing
What is Angle of Attack?
The angle at which the airfoil/fuselage meets the flow of air.
What do rudders control?
