Flight equations Flashcards
1
Q
Equation for true airspeed
A
Vt = M * rt(gammaRaTs)
- gamma = 1.4
- Ra = 287.0529
2
Q
Air density ratio
A
(ro/roO) = (Ps/Po)*(To/Ts)
3
Q
Air density equation
A
ro= Ps/Ra*Ts
4
Q
below what height is the troposphere region
A
11,000m (36,089ft)
5
Q
what equation relates height to temperature in the troposhpere region
A
H= (To-Ts)/Lt =Lt = troposphere lapse rate = 6.5x10^-3
6
Q
given the equation for impact pressure in the exam, what is it equal to
A
Pt - Ps
=Pt = total pressure
7
Q
ratio between total pressure and static pressure is given by
A
Pt/Ps = [1 + ((gamma - 1)/2)*M^2]^(gamma/gamma-1)
8
Q
what is the temperature in the stratosphere
A
same temperature as the troposphere pause height at 11,000 m = 216.65
9
Q
temperature at tropopause height
A
216.65
10
Q
value of Ao
A
340.3
