1.
Isothermal best describes temperature lapse rate in which layer of the lower earth atmosphere?
a)
Mesosphere
b)
Exosphere
c)
Tropopause
d)
Stratosphere
2.
What is the altitude range of the Troposphere?
a)
Surface to 60,000 feet.
b)
35,000 to 60,000 feet
c)
I don't know I don't study or pay attention.
d)
Surface to thirty five thousand feet.
3.
In this atmospheric layer the temperature increases with altitude.
a)
Stratosfear
b)
Tropopause
c)
Troposphere
d)
Stratosphere
4.
The standard lapse rate in the Troposphere is how many degrees and per how many feet?
a)
Decrease of 2 degrees F per thousand miles.
b)
Decrease of 2 degrees C Per 100,000 feet.
c)
Decrease of 3.5 degrees F per Thousand feet.
d)
2.5 Degrees Celsius/1000 feet
5.
Where do most light aircraft fly?
a)
Troposphere
b)
Tropopause
c)
Exosphere
d)
Stratosphere
6.
Why do jets typically fly in the stratosphere?
a)
To avoid the feds.
b)
To experience the jet stream which is located below the tropopause.
c)
To avoid weather.
d)
The air is smoother so less friction and saves jet fuel.
7.
Low air density reduces all of the following except which one?
a)
Engine power
b)
Thrust
c)
Lift
d)
Air density decreases as pressure increases; this is a true principle of air masses however it is inapplicable to this question.
8.
AS air temperature increases what happens to air density?
a)
increases
b)
stay constant
c)
decreases
d)
Density speed increases thereby producing lift.
9.
As humidity increases air density does what?
a)
Decreases
b)
Increases
c)
Gets warmer
d)
Gets colder
10.
A hot humid day is described as a HIGH density ALTITUDE; how does high density altitude affect takeoff roll of an airplane?
a)
A cold dry day shortens take off
roll because the air is more dense. A hot humid (high density altitude) means the air is LESS dense therefore longer takeoff roll required.
roll because the air is more dense. A hot humid (high density altitude) means the air is LESS dense therefore longer takeoff roll required.
b)
Shorter take off roll
c)
More wind
d)
More attitude of aircraft requiring attitude adjustment.
