Atmosphere Airspeed Flashcards
1
Q
ICE T Is Pretty Cool Drink
A
CAS - instrument/position error
EAS - Compressbility
TAS - Density
2
Q
EAS from density alt equation
A
TAS x square root density/msl density
3
Q
IAS/TAS variation with Dynamic Pressure
A
Varies with TAS2
Varies with square root of IAS
4
Q
Dynamic Pressure
A
1/2 x P x v2
5
Q
Mass Flow
A
Volume x Density
- Mass of air with flows through given volume of space
AD Up Mass flow Up
Volume up Mass flow Up
6
Q
Viscocity
A
Description of difficulty of molecule flowing
- frictional forces/air has viscocity
7
Q
Density
A
Density = Pressure/Temp
8
Q
Dynamic Pressure is measure in what units?
A
N/m2
9
Q
Dynamic Pressure is said to vary with…
A
IAS2
10
Q
Ideal Gas Law
A
PV = NRT
Pressure = (N/V) X R X T
11
Q
Ideal Gas law
A
P/rho = R X T
R = Constant
Rho = density
P = pressure
T = temperature
