CPAER CANADA COMMERCIAL PILOT EXAM
ACTUAL QUESTIONS WITH CORRECT
ANSWERS
◉ If a pitot tube becomes blocked but the drain remains clear what
will the Airspeed indicator do?
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?
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?
Answer: It will freeze on the last altitude before blockage
◉ Where can you find the CRFI recommended value for a specific
crosswind?
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?
,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?
Answer: an upper air trough.
◉ What is the difference between a trowal and a trough and how is
each depicted on a GFA?
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?
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?
Answer: 5,200
◉ Define dew point
,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?
Answer: Temperature - Dew point (Dew point spread) x 400.
◉ At what rate does saturated air cool and at what rate does dry air
cool?
Answer: Saturated=1.5 degrees/1000 feet
dry= 3 degrees/1000 feet
◉ Stratus clouds are known for what type of precipitation?
Answer: Drizzle
◉ If winds are veering, which direction are they shifting too?
Answer: Clockwise
◉ Typically during climb out what do the winds do?
Answer: Veer and increase
◉ What is the Air mass that usually occurs only in the winter time
over Canada?
, Answer: continental Arctic (cA)
◉ What is the Air mass that usually occurs only in the summer time
over Canada?
Answer: Maritime Tropical (mT)
◉ What are the two air masses that are very rare for Canada?
Answer: cP and cT.
◉ Decode the following METAR: RMK SF5NS3 SLP134
Answer: Remarks:5 oktas Stratus fractus 3 oktas Nimbostratus Sea
level pressure: 1013.4 hPa
◉ Decode the following METAR: RMK SN2SC6 SLP270
Answer: Remarks: 2 oktas Stratus Nimbus 6 oktas stratus cumulus
Seal level pressure: 1027.0 hpa
◉ How do you calculate the Freezing level within a cloud?
EG= Elevation 900 ft
Surface Temp = 24 c
Dew Point = 15 C
Answer: 1. First get the Cloud Base (Dew point Spread X 400)
