Hey guys,
I have a few questions for anyone who currently flies a metro. I've received different and conflicting answers from fellow pilots, and I was hoping for added input.
1. In my groundschool manual (electrical systems chapter, DC voltmeter switch), it states..... "to read the output of the selected generator or battery, the corresponding battery or generator must be in the OFF position. If left ON, the voltmeter will read DC Bus voltage." I don't quite understand this. Does this mean that if I want to read the voltage of the left generator in flight, I would actually have to turn the left gen OFF?
2. Do you know what the 3 CBs in the wheel well are for? I believe one is the CB for the Generator output sense relay, the 2nd is the CB for the ground fault sensing relay, and the 3rd is the CB for the Gen relay. There is also a 4th CB on the opposite side, which I believe is the CB for the voltmeter. I'm not too sure though.
3. I do not understand the purpose of the "Reset" position for the battery and generator switches. The manual explains it acts to "prime" the generator. I dont see how this works.
4. There are 4 static ports on the nose. I know they are all for the pressurization system, but what exactly is each one for? I know 1 is for the 7.25 PSI relief valve for dump valve,.
5. If the trim system fails, you apparently will get a heavy nose up pitch. Why is this?
If anyone can shed some light on any of these questions, I'd greatly appreciate it. Thanks a lot.
