AE Flashcards
What is done when a force acts upon a body and moves it?
Work
What is a vector?
A quantity that indicates magnitude and direction
What is force?
A push or pull exerted on a body
F=M(A)
What is mass?
The quantity of molecular material that comprises an object
What is volume?
The amount of space occupied by an object
What is density?
The mass per unit of volume (Mass/Volume)
What is power?
The amount of work done over a period of time (Rate)
What is weight?
The force with which a mass is attracted to the the earth by gravity
What is kinetic energy?
Energy of motion
How many knots TAS will you gain as altitude increases?
3 kts per 1000 feet
What happens to air density and temp as altitude increases?
Both decrease
What atmospheric properties affect pressure?
Temperature and Density
What is total pressure?
Dynamic plus static pressure.
Define True Altitude
Height above sea level (MSL)
Define Pressure Altitude
Height above the standard datum plane. (29.92)
Define Density Altitude
Pressure altitude corrected for temperature
What is the Standard Lapse Rate?
2 °C for every 1000 feet
The measure of the average kinetic energy of air particles is called?
Temperature
Define Static Pressure
The force that air molecules exert upon one another by their random movement
Define Dynamic Pressure
The measure of impact pressure of a large group of air molecules moving together
Define Indicated Airspeed
Airspeed read off the indicator
Define Calibrated Airspeed
Indicated airspeed corrected for indicator errors or minor position errors
Define True Airspeed
The actual speed at which an aircraft moves through an air mass
Define Groundspeed
True Airspeed corrected for winds
