Kinematics (One Dimension)
Displacement is a vector quantity; it possesses both what?
a magnitude and a direction
To describe motion, we must deal with these three?
velocity, acceleration, and displacement
What is the formula for wing area?
Wingspan x Chord
A standard pressure lapse rate is when pressure decreases at a rate of
1' of mercury (HG) per 1,000'
How many dogs do I have?
Three
instantaneous speed is the counterpart to what aspect of instantaneous velocity?
magnitude
This path of the aircraft is then to initially descend slightly before beginning to move upwards when calculating for kinematics.
resultant
The maximum lift-drag ratio, (L/DMAX) occurs at these specific points
angle of attack and lift coefficient.
Your aircraft is performing in the following conditions what type of density altitude are you experiencing?
Decreased aircraft performance
Low pressure and high humidity
High Density Altitude
How many fish do I have?
Four
An object in free fall experiences an acceleration of what?
-9.8 m/s2
An object in free fall experiences an acceleration of -9.8 m/s2. (The - sign indicates a downward acceleration.) Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s2 for any freely falling object.
The horizontal and vertical components of two-dimensional motion are ________of each other. Any motion in the horizontal direction does not affect motion in the vertical direction, and vice versa.
independent
What is the formula for reynolds number?
RE=ρVc/μ=
air density (speed)wing chord)/mu
Calculate the following scenario for pressure altitude.... (make sure you provide units in your answer)
Altimeter: 30.25
Field elevation: 1,273ft
29.92-30.25*1000+1273 =
943'
What is my second favorite color?
Red
What is the basic formula for acceleration?
Vf = Vo + at
to resolve (break) it into motions along perpendicular directions. Resolving two-dimensional motion into perpendicular components is possible because the components are independent.
Projectile Motion
What is the induced drag formula?
Di=CDi qS
This density altitude factor is not generally considered a major factor in density altitude computations because its effects are related to engine power rather than aerodynamic efficiency.
Humidity
With which company did I hold my initial aircraft dispatch position
Air Wisconsin
Using the relationship between dependent and independent variables, we see that the slope in the graph is average velocity. What is the formula associated with this statement?
Hint: Graph of Position vs Time
x=vt+ x0
OR
x= x0+ vt
If the perpendicular components Ax and Ay of a vector A are known, then A can also be found analytically. To find the magnitude A and direction θ of a vector from its perpendicular components Ax and Ay , we use the following relationships:
A =√(Ax2+ Ay2
θ = tan-1(Ay/Ax)
What is the induced drag coefficient formula?
CDi=CL sin αi
Calculate the following scenario for density altitude.... (make sure you provide units in your answer)
Altimeter: 29.90
Field elevation: 1,273ft
Pressure Altitude: 1,293ft
OAT: 30 degrees C
ISA: 14 degrees
1,293 + [120 x (30 - 14)] = 3,213'
What state was I born in?
New York State
