Aircraft General Knowledge Quiz! Trivia

Have you ever seen an aircraft? They are pretty cool to look at when they are up in the air. An aircraft can use either static or dynamic lift, or sometimes the downward thrust of jet engines. Some examples of aircraft include airplanes, helicopters, airships, and hot air balloons. Get ready for this quiz with well-researched questions on aircrafts and prepare for take-off. You can do it.

    • A. 

      Is normal because the engine is usually stopped by moving the mixture to idle cutoff
