CPAER CANADA COMMERCIAL PILOT EXAM QUESTIONS
WITH ANSWERS GRADED A+ 2025/2026
What does a double purple line indicate on a GFA? - an upper air trough.
What is the difference between a trowal and a trough and how is each depicted on a
GFA? - 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? - 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? - 5,200
Define dew point - 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? -
Temperature - Dew point (Dew point spread) x 400.
At what rate does saturated air cool and at what rate does dry air cool? - Saturated=1.5
degrees/1000 feet
dry= 3 degrees/1000 feet
Stratus clouds are known for what type of precipitation? - Drizzle
If winds are veering, which direction are they shifting too? - Clockwise
Typically during climb out what do the winds do? - Veer and increase
What is the Air mass that usually occurs only in the winter time over Canada? -
continental Arctic (cA)
What is the Air mass that usually occurs only in the summer time over Canada? -
Maritime Tropical (mT)
What are the two air masses that are very rare for Canada? - cP and cT.
Decode the following METAR: RMK SF5NS3 SLP134 - Remarks:5 oktas Stratus fractus
3 oktas Nimbostratus Sea level pressure: 1013.4 hPa
,Decode the following METAR: RMK SN2SC6 SLP270 - 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 - 1. First get the Cloud Base (Dew point Spread X 400)
1. Eg: 3,600 + 900 = 4500 ASL
2. Then get the "new dew point (DP- (.5x(cloud base/1000)
2. Eg: 15- (.5x (3,600/1000)= 13.2
3. New DP/1.5 X1,000
13.2/1.5X1,000
4. Add that to the Base plus Elevation = freezing level.
4 eg: 3,600 +8,800 =12,400 AGL + 900 = 13,300 ASL
Btw, this is Bullshit! As the saturated lapse rate is not very steady
In a METAR regarding RVR what do the following codes means? D, U, N - Downward
Trend, Upward Trend, No change.

What is the following Barometric Pressure: SLP833 - 983.3 hPA
What is the following Barometric Pressure: SLP751 - 975.1 hPA
What is the following Barometric Pressure: SLP145 - 1014.5
What is the True Airspeed Rule of Thumb under standard conditions? - Add an
additional 2% of CAS for every thousand Feet to get TAS
For route planning should you use KIAS or KTAS to determine ground speed? - KTAS
What is the difference between the MEA and the MOCA - MEA is the Minimum En route
altitude which provides obstruction clearance as well as navigational signal coverage.
MOCA (minimum obstacle clearance altitude) provides Obstacle clearance but only
provides navigational signal for only 22 NM from a VOR
What is the frequency range for VORs - 108.0-117.95 MHz
What is the frequency range for voice transmissions within the Airband? - 118-136.975
MHz
, What must a pilot do to stay current? - 1. Every 6 months: Complete 5 takeoffs and
landings to carry passengers. If flying at Night, the TO/Landings must be at night as
well.
2. Every 2 years: Complete (one of the following); Flight Review, TC Aviation Seminar,
TC approved recurrent Training Program, Self paced study program, PPC.
3. Every 5 years: Fly as PIC or SIC at least once in a Category of AC for which you're
licensed.
Mult-engine PIC (PPC or PCC) - PPC
Multi-engine SIC requiring a type rating (PPC or PCC) - PCC
Single-engine aeroplanes flown with passengers night VFR or with passengers IFR
(PPC or PCC) - PPC
What type of flying requires a PPC (3 items) - 1. Multi-engine aeroplanes
2. Single-engine aeroplanes flown with passengers night VFR or with passengers IFR
3. Aeroplane requiring a type rating SIC must complete a PPC initially for the type rating
(if the pilot does not have the type rating)
What type of flying requires a PCC (3 items) - 1. Single-engine aeroplanes flown with
passengers or cargo day VFR.
2. Single-engine aeroplanes flown with cargo only night VFR or cargo only IFR
3. Multi-engine SIC of an aeroplane requiring two-crew (type rating) VFR or IFR (The
PIC would do the PPC every time)
What is the Requirement for caring a Journey Log on board and what is the requirement
for Filing a Flight Plan or Flight Itinerary. - 1. Journey Log must be carried anytime the
engine will be shut down other than the departure Airport..
2, Flight Plan or Itinerary for all flights beyond 25 NM radius from the departure
aerodrome.
For VFR OTT, the minimum weather conditions required at destination must be forecast
to exist. . . . before to . . . . . after the ETA when using a TAF and . . . . . before to . . . . .
after the ETA when using a GFA (if no TAF exists). - 1 hour, 2 hours, 1 hour, 3 hours
Flight Crew members for an air taxi Services must make _____ takeoffs and landings in
_________ ___________ - 3 90 days
An air taxi operator must conduct emergency training procedures... - initially and
annually.
