In a carburetor the fuel to air ratio is governed by... - CORRECT ANSWER - Mass (or
weight)
What happens to the Fuel/Air ratio when Carb heat is applied? As a result what should you do
for prolong carb heat usage. - CORRECT ANSWER - Air is warmer therefore less dense
so you should lean the mixture for prolong use of Carb heat.
What happens to an engine when fuel is not leaned at high altitudes? - CORRECT
ANSWER - the fuel to air mixture becomes too rich this results in a drop of RPMs and
spark plugs may foul. This will also result an more fuel used than calculated as per the POH.
What happens when you lean the mixture at cursing altitude? - CORRECT ANSWER -
You are decreasing the amount of fuel to air ratio to compensate for the less dense air at higher
altitudes.
When Carb heat is applied what happens to the fuel to air ratio? - CORRECT ANSWER -
The fuel gets richer because the air becomes less dense.
As the Angle of attack is increased what happens to lift and induced drag? - CORRECT
ANSWER - They both increase.
,The First Symptom of Carburetor icing is
a. Engine Roughness
b. RPM decrease - CORRECT ANSWER -b
A turbo Charger is powered by __________ _________ and a supercharger is powered by _____
_________ - CORRECT ANSWER - Exhaust gases, internally driven compressor
powered by the engine.
If the pitot tube and its drain becomes blocked What would the Airspeed indicator do? -
CORRECT ANSWER - Act like a VSI or altimeter
If a pitot tube becomes blocked but the drain remains clear what will the Airspeed indicator do? -
CORRECT ANSWER - This is a partial block which will allow the dynamic pressure to
slowly leak out. In this case the ASI will decrease to 0
What will happen to the Airspeed indicator if the static port gets blocked? - CORRECT
ANSWER - It will under-read more and more as you climb and over read more and more
as you descend.
What will happen to the altimeter if the static port gets blocked? - CORRECT ANSWER -
It will freeze on the last altitude before blockage
Where can you find the CRFI recommended value for a specific crosswind? - CORRECT
ANSWER - Under that specific crosswind in the Chart titled Crosswind limits for CRFI
What is a trough and how is it depicted on a GFA? - CORRECT ANSWER - It is an
elongated are of low pressure and is shown as a single purple line.
What does a double purple line indicate on a GFA? - CORRECT ANSWER - an upper air
trough.
, What is the difference between a trowal and a trough and how is each depicted on a GFA? -
CORRECT ANSWER - A Trowal (or an occluded front) occurs when cold air catches up
with warm air. It is shown on the GFA as zipper cold and warm front. A trough is an elongated
area of low pressure. It is shown on the GFA as a single purple line.
You takeoff with and the field altimeter setting is 30.12. Along the route while level at 5,000 you
check the AWOS at a nearby airport and it 30.02. What altitude are you actually at? - CORRECT
ANSWER - 4,900
You takeoff with and the field altimeter setting is 29.80. Along the route while level at 5,000 you
check the AWOS at a nearby airport and it 30.00. What altitude are you actually at? - CORRECT
ANSWER - 5,200
Define dew point - CORRECT ANSWER - The temperature to which air must be cooled
at a constant pressure to becomes saturated.
How do you estimate the base height of a cloud using the dew point and temperature? -
CORRECT ANSWER - Temperature - Dew point (Dew point spread) x 400.
At what rate does saturated air cool and at what rate does dry air cool? - CORRECT
ANSWER - Saturated=1.5 degrees/1000 feet
dry= 3 degrees/1000 feet
Stratus clouds are known for what type of precipitation? - CORRECT ANSWER - Drizzle
If winds are veering, which direction are they shifting too? - CORRECT ANSWER -
Clockwise
Typically during climb out what do the winds do? - CORRECT ANSWER - Veer and
increase
