Parts of a Plane
Name the 5 main components of a plane.
Emmanage, Fuselage, Wings, Cockpit, Landing Gear
What is a mean camber line?
The line depicts the average of the lower and upper camber.
What is a Knot?
1 nautical mile per hour
When you go up in altitude, what happens to the temperature, pressure, and density?
It decreases!
What's the difference between dynamic and static stability? and what are the 3 types of each (just name them don't define them)
Static stability is directly affected by a disturbance to the equilibrium.
Dynamic stability is the extended period of stability after a disturbance to equilibrium.
Positive, Negative and neutral.
Name the 3 main controls on a plane that control the yaw, roll, and pitch.
Rudder
Ailerons
Elevators
How would I know if an airfoil is symmetric or not using an AOA vs. Cl. graph?
Check if the curve/line goes through (0,0). If it does, then it is symmetrical.
What is a moment? And what do I need to multiple a force by to get a moment? (be specific)
- a rotational force
- a perpendicular distance
What atmospheric characteristic has the MOST affect on aircraft performance?
Air Density
What are the components that make up TOTAL DRAG?
Parasitic Drag and Induced Drag
The structural supports inside a wing, what are they called, and what direction do they go in relation to the wing? (There are 2)
Rib - Lateral to the wing (longitudinal with the body)
Spar - longitudinal with wing (lateral with body)
What edge of my airfoils would my slats and flaps be?
Leading Edge - Slats
Trailing Edge - Flaps
What are 3 variables that influence density in the atmosphere?
Height/Altitude
Temperature
Pressure
Why do pilots lose consciousness at high altitudes?
Due to low air pressure
What is an aspect ratio? And do I want a higher or lower one for more stability?
The ratio of a wingspan to the average wing width.
I would want a higher aspect ratio for greater stability.
Name 5 different component possibilities on the wing of a plane?
Ailerons, trim tab, slats, flaps, spoilers, winglets ect.
What does the Coefficient of Lift Represent?
The relationship between the shape of the airfoil and the angle of attack.
What is a Newton's units, what does it measure, and in what system?
- kg x m /s^2
- Force
- Metric
Name the 4 concepts that allow a wing to produce lift?
Hint: it's not vector
Bernoulli's
Coanda Effect
Circulation
Deflection Force / Newton's 3rd Law
Explain why 4 of Spades is an inside joke in this class.
A video we watched showing the effects of hypoxia, and what happens to someone at a high altitude with an unpressurized cabin, not getting enough oxygen to their brain.
What is a Pitot Tube/how does it work, and what 3, six-pack instruments does it manipulate?
An exterior instrument used on aircraft to measure total air pressure.
- Relative Airspeed Indicator
- Vertical Airspeed Indicator
- Altimeter
What is the definition of AoA, and what is my Critical AoA?
The angle between the chord and the relative wind.
Critical Angle of attack: the maximum angle between the wing's chord line and the relative wind before the wing loses lift and stalls, indicated on a Cl AoA chart by the point before the max point.
Can you write out the Lift equation (or coefficient of lift equation) on the board and identify the variables properly?
L = (Cl x A x p x v^2 ) / 2
When referring to a center of gravity & moment envelope graph, what does it mean to be in front of the "safe zone", behind the safe-to-fly zone, and above the safe-to-fly zone?
Above - aircraft weighs too much
In front - your center of mass/gravity is too far forward
Behind - your center of mass/gravity is too far aft/back
Name the 3 rotational Axis of a plane, what the rotational movement is called around each axis, what parts of a plane control its movement, and what controls a pilot would use to make these movements.
Vertical- Yaw - Rudder - Foot pedals
Longitudinal - Roll - Ailerons - Yoke turn
Lateral - Pitch - Elevator - Pull yoke
