Q

If you have a decrease in outside air pressure and outside air temperature, what is going to happen to the thrust output of an engine and why?

A

Q

If the pitot tube and the drain hole get clugged, what happens to the airspeed indicator?

30% 40%
38
FPD
Freezing Point Depressant
39
What is the two step de-icing process?

43
When are wing tip vortices produced?
Anytime an airplane is producing lift.
44
When is the most dangerous ground condition in terms of wing tip vortices?
When you have a light quartering tailwind.
45
When is hydroplanning most likely to occur?
- When you have standing water or slush - High speeds - Smooth runway
46
Dynamic hydroplanning
Occurs at high speeds
47
What is the formula for when dynamic hydroplanning occurs?
9 times the square root of the tire pressure
48
Viscous hydroplanning
Requires a smooth runway, occurs at slow speeds
49
Reverted rubber hydroplanning
When you lock the wheels, create friction, change water to steam, and you hydroplan on the steam.
