The average height of the troposphere at the equator is?
54000 ft
The condition where pressure altitude and density altitude are the same value is?
Standard atmosphere
Isobars are spaced on weather charts at ___ millibars.
4
En route at FL290 with the altimeter set correctly but not reset to the local altimeter
setting of 30.57 in Hg during the descent. If the field elevation is 650 feet ASL and the
altimeter is functioning properly the approximate indication upon landing is?
0 ft
En route at FL290 and the altimeter is set correctly but you fail to reset it to the local
altimeter setting of 30.26 in Hg during the descent. If the field elevation is 134 feet
and the altimeter is functioning properly it would indicate after landing?
-206 ft

Which best defines dew point?
a. The temperature that the air must be cooled to in order to drop below 100%
relative humidity.
b. The temperature that the air must be cooled to in order to become saturated.
, c. The temperature of the air at 50% relative humidity.
d. None of the above.
B
If the wind is from the north the area of low pressure is to the?
East
As altitude is gained the winds tends to?
Veers and increase
The surfaces of fronts generally slope at an a angle of?
0.5 to 1.5°

Snow --> Ice Pellets --> Freezing Rain --> Rain
It is true regarding an occluded front that
a. an advancing warm front overtakes a cold front and pushes air up as it advances
creating a wave.
