What is a ceiling?
Give this one a try later!
The lowest layers of broken or overcast clouds
Which has more turbulence, a sharply curving or straight jet stream?
Give this one a try later!
sharply curving
Different stages of thunderstorms
,Give this one a try later!
Cumulus,Mature, and Dissipating
Layers of the atmosphere
Give this one a try later!
Troposphere, Stratosphere, Mesosphere, Thermosphere
When does structural icing occur?
Give this one a try later!
During flights through clouds or liquid precipitation when the skin
temperature of the aircraft is equal to, or less than 0 degrees Celsius
With a warm front, when is the most critical period of Low Level Wind Shear (LLWS)?
Give this one a try later!
Before the front passes
Most serious icing occurs?
Give this one a try later!
, Right below 0 C
How do you calculate a ceiling?
Give this one a try later!
Temp-Dew point / 4.4 x 1000
Scales of circulation refers to what?
Give this one a try later!
the sizes and lifetimes of individual circulations?
Ice,snow or frost on the leading edge and upper surface of a wind can reduce lift and
increase drag by how much?
Give this one a try later!
Reduce lift by 30% and increase drag by 40%
Advection fog and upslope fog are dependent on?
Give this one a try later!
, wind
Why is frost considered hazardous to flight?
Give this one a try later!
because it spoils the smooth flow of air over the winds, thereby decreasing
lifting capability
When can a pilot expect a wind shear zone in a surface-based temperature inversion?
Give this one a try later!
Whenever the wind speed at 2,000 to 4,000 ft above the surface is a least
25 knots
