Question 1
If the pitot tube and its drain becomes blocked, what would the airspeed indicator do?
Correct Answer:
Act like a VSI or altimeter
Explanation:
When the pitot tube becomes blocked, the airspeed indicator is unable to receive the dynamic pressure that allows it to measure the aircraft’s speed through the air. In this situation, the airspeed indicator starts to behave like an altimeter or vertical speed indicator (VSI), depending on the altitude changes the aircraft experiences. If the aircraft is in level flight and the air pressure remains constant, the airspeed indicator will freeze at the last indicated speed. However, if the aircraft climbs or descends, the static pressure will change, and the airspeed indicator will respond to these changes based on the variations in the static pressure, similar to how an altimeter or VSI would reflect altitude changes. This unique situation arises because the airspeed indicator relies on both static and dynamic pressures. When only static pressure is available due to a blocked pitot tube, its behavior mimics that of altimeters or VSIs, which respond to changes in atmospheric pressure.
Question 2
When transitioning from an altimeter setting region to a Standard Pressure Region, when should the altimeter be set to 29.92?
Correct Answer:
Just after entering the SPR
Explanation:
When transitioning from an altimeter setting region, where local air pressure varies, to a Standard Pressure Region (SPR), the appropriate moment to set the altimeter to 29.92 inches of mercury (inHg) is just after entering the SPR. This timing is crucial for maintaining accurate altitude readings as the aircraft enters an environment where the altimeter must reflect the standard atmospheric pressure for the control of air traffic and navigation. Setting the altimeter as soon as you cross into the SPR ensures that your altitude reporting aligns with standard atmospheric practices, which is vital for safety in controlled airspace and when flying at higher altitudes. If you set the altimeter before entering, you could risk having an inaccurate altitude reading as local pressures still apply until you are physically in the SPR. Setting it only after you are within the SPR ensures that the transition is effective, providing clear and standardized altitude readings for both the pilot and air traffic control, aligning with the operational practices established by aviation authorities. The necessity of performing this adjustment immediately after entering the SPR also supports maintaining situational awareness and compliance with regulations concerning altitude reporting.
Question 3
What is the minimal requirement for a rest period before the next duty day following an extended flight time?
Correct Answer:
6 consecutive hours
Explanation:
The minimal requirement for a rest period before the next duty day following an extended flight time is 6 consecutive hours. This standard is established to ensure that pilots have adequate rest and recovery time after long periods of flying. Adequate rest is essential for maintaining cognitive function, decision-making skills, and overall safety in aviation operations. Following extended flight hours, pilots may experience fatigue, which can impair their ability to perform needed tasks effectively. Therefore, regulations mandate this minimum rest period to help counteract the effects of fatigue and to ensure that pilots are alert and fit for duty on the subsequent day. Other options, while they may suggest shorter rest periods, do not adhere to the established safety regulations that prioritize pilot well-being and operational safety.
Question 4
What is indicated by a very high or full-scale reading on an ammeter?
Correct Answer:
There is a malfunction of the voltage regulator
Explanation:
A very high or full-scale reading on an ammeter indicates an electrical issue, most commonly associated with the function of the voltage regulator. In a properly functioning system, an ammeter should show normal current flow corresponding to the operational needs of the aircraft’s electrical system. If the ammeter reads exceptionally high, it suggests that the voltage regulator is failing to effectively manage the charging process, allowing too much current to flow into the battery or electrical system. This malfunction could result in overheating and damage to components, indicating that the regulator is not properly limiting the voltage output. Therefore, when faced with this kind of reading, it is essential to diagnose and address the issue related to the voltage regulator to avoid potential electrical system failure. High readings on the ammeter do not directly indicate battery state, such as being fully charged or discharging, and they do not provide information about the function of the voltage regulator as operating correctly. Hence, recognizing a full-scale reading as indicative of a malfunction in the voltage regulator is crucial for maintaining the safety and reliability of the electrical system in aviation.
Question 5
How many takeoffs and landings must flight crew members for an air taxi service perform within a 90-day period?
Correct Answer:
3 takeoffs and landings
Explanation:
Flight crew members for an air taxi service are required to perform a minimum of three takeoffs and three landings within a 90-day period to maintain their currency for that specific operation. This requirement ensures that pilots are proficient in maneuvering the aircraft safely, which is vital for passenger transport and cargo operations typical to air taxi services. Performing three takeoffs and landings also aligns with regulatory standards designed to enhance safety and provide adequate practice, thus preparing pilots for the unique challenges of their flying duties. Both fewer and higher numbers, such as two or four takeoffs and landings, do not meet the established regulatory or operational standards, which explicitly specify the necessity of three to ensure that flight crew members are competent and confident in flying and landing the aircraft effectively.
Question 1
Exam overview

About this Exam

The Commercial Pilot Licence—Aeroplane (CPAER) is a fundamental certification issued by Transport Canada, marking a significant milestone in an aviator's professional journey. This designation is essential for pilots who wish to be compensated for their flying services, moving beyond the privileges of a private pilot and stepping into commercial operations. The official CPAER written exam is a rigorous test that candidates must pass to satisfy the knowledge requirements for this licence.

Our comprehensive CPAER Canada Commercial Pilot Practice Exam study guide is designed specifically for student pilots who have completed or are near completion of their commercial pilot flight training. It acts as a crucial preparatory tool for those transitioning from private to commercial piloting, ensuring they possess the deep theoretical knowledge and practical understanding required for professional airline and charter operations across Canada.
