Transport Canada Drone Pilot Exam: Small Basic (Remotely Piloted Aircraft Systems - Basic Operations)
RPAS systems: practice questions
Our Canada drone Basic exam bank has 25 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
The nominal voltage of one lithium polymer (LiPo) cell is about:
- 1.5 V
- 3.7 V
- 4.8 V
- 12 V
Show the answer
B. 3.7 V — A LiPo cell is about 3.7 V nominal and about 4.2 V fully charged.
Question 2
A battery's energy in watt-hours (Wh) is found by:
- Dividing capacity by voltage
- Adding voltage and capacity
- Multiplying voltage by capacity in amp-hours
- Multiplying the C rating by the number of cells in series
Show the answer
C. Multiplying voltage by capacity in amp-hours — Wh = V x Ah. For example, 14.8 V x 5 Ah = 74 Wh.
Question 3
Compared with brushed motors, brushless motors are:
- Less efficient and noisier
- More efficient and longer lasting
- Heavier and need more maintenance
- Used only on fixed-wing aircraft
Show the answer
B. More efficient and longer lasting — Brushless motors have no wearing brushes, giving higher efficiency and longer life.
Question 4
A drone battery is rated 14.8 V and 5,000 mAh. Its energy is about:
- 74 Wh
- 20 Wh
- 148 Wh
- 5 Wh
Show the answer
A. 74 Wh — 5,000 mAh = 5 Ah; 14.8 V x 5 Ah = 74 Wh.
Question 5
A drone's GPS position-hold mode differs from attitude mode in that:
- It turns off the motors
- It flies faster
- It disables the compass and uses only the barometer to hold position over the ground at all times
- It holds position over the ground; attitude mode only levels the aircraft and lets it drift
Show the answer
D. It holds position over the ground; attitude mode only levels the aircraft and lets it drift — TP 15263 describes autopilot modes: manual, attitude and GPS position hold.
