During the practical test, if you are unsure of an answer, what should you do?

When faced with uncertainty during a practical test, admitting that you do not know the answer and offering to look it up is the most professional approach. This response demonstrates your integrity and commitment to safety in aviation, as it shows you prioritize obtaining accurate information over providing potentially incorrect answers. It also reflects an understanding that as a pilot, it is crucial to seek accurate data rather than make uninformed decisions, especially when the safety of the flight might be at stake.

By suggesting that you would look the information up, you are indicating that you respect the procedure and protocols of flying, which encourages a culture of safety and accuracy. This approach can highlight your willingness to learn and ensure that you have the right knowledge necessary for safe flying practices. Properly acknowledging the limits of your knowledge and being proactive in seeking the correct information can often leave a more favorable impression on the examiner compared to other methods like guessing or diverting the conversation.
