I am a strong advocate of teaching/learning especially when it is taken to heart. Initially, there are no stupid questions.
Yes,
initially a novice can use that defense for questions but once the question is answered by those who know, it is no longer a learning situation.
Those who fly and who know about MELs and CDLs and systems have tried to explain that test flights for minor systems problems is not warranted anymore than a test drive in your car after replacing the knob on your radio. But some persist... and therein is the problem.
NO ONE knowingly takes an an airplane, car, bicycle, skates, horse that they think is defective and will cause injury and/or death once they attempt to use it. Often there seems to be some suspension of reality when it comes to applying normal human consideration and reasoning when it comes to airlines, pilots and flying. It is as if pilots and mechanics, who do this stuff everyday, have no understanding of consequence. Rubbish! and silly rubbish at that.
