So, at night the reg states we need to have one spare set of fuse, or three spare fuses of each kind required that are accessible to the pilot in the flight.

So let us say, we have fuses of three different resistant; say 7,8, 10, then we need three of 7, three of 8 and three of 10 fuses during flight?

I fly C172SP and so far I have never heard of fuses on this model.

    This is where common sense has to come into play.

    If an aircraft has circuit breakers and no fuses, then a spare set of fuses would not be necessary.

    It sounds as if you are stuck at the rote level of learning with regard to this regulation.

    LOL! I did a night flight with a student and during the preflight he asked where the spare fuses were. I asked him where they would go if we wanted to replace one in the plane in flight. It was a C172P which, if I recall correctly, has a total of two fuses (one of which is for the old cigarette lighter), both of which are behind the instrument panel and not particularly accessible in flight

    Thanks Mark !

    Hey Kris, Yes I do have common sense but do not have sense in common between two of us!

    I think that is not pretty much the answer I am looking for, and you students should be having great time with your harsh attitude…

    My students would know the answer, because I would teach them.

    There is nothing harsh about pointing out the obvious.

    This is the problem with a generation that has been molly-coddled and made to believe that one’s sense of self esteem is the most important thing in the world.
