1) I've read it and read it, I know how to calculate it all because of physics, but I cannot understand why AC is better than DC in a generator operated aircraft.

Correct me if I'm wrong but is it like this.... Volts*amps=watts. A guage needs x amount of watts to operate. By upping the volts you get to lower the amps to equal x amount of watts. Less amps mean less pull so you can have smaller wiring ect, less weight, smaller instruments. Is that correct?

After studying the schematics I've notice the 115v systems on the Merlin for the most part only pull 1amp. So i'm assuming that when running with the higher voltages you can get the smaller guages and systems.

So if you can have an AC system by using an inverter on the DC generators which makes everything lighter and pull less amps off the battery then why would you run something off DC? Is it because something, such as our nose wheel stearing, needs more electrical pull to work and if you went with the higher volts and that many amps you'd start melting wires?

I'm trying to understand why use one system over the other. Esp what the advantages are with a 26v AC system over the 26V DC system. DC offers redundancy because the generators are DC no? I haven't taken flight saftey yet for the aircraft so I'm trying to learn the aircraft on my own during my spare time.

2) Why do some part 141 schools offer the CFII as their initial instead of the CFI. I know some do but while sitting here I can't remeber what the reason was behind it. The bossman asked and for the life of me I couldn't remember.
