Question 47

What happens to Kinematic Air Viscosity as altitude INCREASES.

Answer 47

It goes up. Kinematic air viscosity is viscosity/density. Because density decreases faster than viscosity Kinematic Viscosity goes up because the density denominator is getting smaller quicker.

Question 48

TAS relationship to altitude and temperature.

LSS vs. Temperature

Answer 50

LSS decreases with a decrease in Temperature

Question 51

Mach vs. Altitude

Answer 51

Mach will increase with altitude for a constant IAS because TAS is increasing and LSS is decreasing. Mach will also increase with altitude IF TAS is constant because TAS will decrease with a decreasing temp.

Answer 53

LSS decreases with Altitude ONLY if the temperature decreases also.
