CPAER CANADA COMMERCIAL PILOT
EXAM 2025 QUESTIONS AND ANSWERS
How Long is Cat 3 Medical Exam Good for if over 40? - ANS 2 years
Does a CAT 1 Medical time period start on the Exam date or Issuance date? - ANS Exam Date
A Pilot Proficiency Check (PPC) and ___________ __________ are very similar. Except a PPC
may be required for IFR currency requirements. - ANS Competency Check
What is the difference between an AOC and a COA? - ANS AOC= Air Operator's Certificate
COA= Certifcate of Airworthiness
Maximum Air Speed Rules are always in what type of Airspeed? - ANS Indicated Knots (KIAS)
When flying from a altimeter setting region to a Standard Pressure Region you should set your
altimeter to 29.92 just __________ entering the SPR - ANS After
What is the main difference between a reportable aviation incident and accident? - ANS a
Reportable aviation Incident does not apply to small aircraft (> 5,700 kg). It covers emergencies
(fire, going off runway, Control issues) that could have resulted in a major accident.
Pilots operating at an uncontrolled Aerodrome at which no ground station exists or frequency is
published should broadcast on - ANS 123.2
1 @COPYRIGHT THEBRIGHT 2025/2026
,When is refueling of an air taxi flight not permitted with passengers on board? - ANS When
the pilot-in-command is not available to monitor the fueling
how many hours can a flight crew log in a 24 hour period? If the pilot is single engine IFR how
many hours can be logged? - ANS 14 and 8
When should you carry a journey Log on an Aircraft? - ANS At all times unless the aircraft will
not land and shutdown at another location.
When penetrating the ADIZ ETA must be within ________ minutes and _________ NMs. -
ANS 5 20
In a carburetor the fuel to air ratio is governed by... - ANS 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. - ANS 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? - ANS 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? - ANS 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? - ANS The fuel gets richer
because the air becomes less dense.
As the Angle of attack is increased what happens to lift and induced drag? - ANS They both
increase.

,The First Symptom of Carburetor icing is
a. Engine Roughness
b. RPM decrease - ANS b
A turbo Charger is powered by __________ _________ and a supercharger is powered by
_____ _________ - ANS Exhaust gases, internally driven compressor powered by the engine.
If the pitot tube and its drain becomes blocked What would the Airspeed indicator do? -
ANS Act like a VSI or altimeter
If a pitot tube becomes blocked but the drain remains clear what will the Airspeed indicator do?
- ANS 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? - ANS 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? - ANS It will freeze on the
last altitude before blockage
Where can you find the CRFI recommended value for a specific crosswind? - ANS Under that
specific crosswind in the Chart titled Crosswind limits for CRFI
What is a trough and how is it depicted on a GFA? - ANS 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? - ANS an upper air trough.
3 @COPYRIGHT THEBRIGHT 2025/2026
, What is the difference between a trowal and a trough and how is each depicted on a GFA? -
ANS 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? -
ANS 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? -
ANS 5,200
Define dew point - ANS 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? -
ANS Temperature - Dew point (Dew point spread) x 400.
At what rate does saturated air cool and at what rate does dry air cool? - ANS Saturated=1.5
degrees/1000 feet
dry= 3 degrees/1000 feet
Stratus clouds are known for what type of precipitation? - ANS Drizzle
If winds are veering, which direction are they shifting too? - ANS Clockwise
Typically during climb out what do the winds do? - ANS Veer and increase
