CPAER Canada Commercial Pilot Practice Exam

Question: 1 / 480

How long must a pilot wait to fly after receiving a local anesthetic?

12 hours

24 hours

The correct waiting period for a pilot after receiving a local anesthetic is 24 hours. This time frame is crucial as it accounts for the potential effects that the anesthetic might have on a pilot's cognitive and motor functions, even if those effects are expected to be minimal.

While local anesthetics do not typically induce the same systemic effects as general anesthesia, the regulation specifies a waiting period to ensure that pilots can operate aircraft safely and reliably. The 24-hour duration allows for any residual sensations or side effects from the procedure to dissipate, ensuring that the pilot's performance is not compromised.

The other time frames provided do not align with the recommendations or regulations concerning the effects of local anesthetics on flying capabilities. Adhering to the 24-hour rule helps maintain safety in aviation by ensuring that pilots are fully capable of managing the responsibilities of flight.
