Using a 24V system (higher pressure to us mechanical guys), you c=
ould get away with a smaller wire or run higher currents. I would thin=
k there would be an advantage to this.<
The only advantage to going with a 28V system is to save weight. The
longer the electrical runs and the bigger the aircraft the more likely
there is a significant weight advantage. For the tiny 320/360 the very
small savings in weight is more than offset by the added cost of 28V
equipment. For the larger IV and with owners having larger pocket books
the decision would be more difficult. Some of the upper end avionics only
come with 28V requirements.
28V electrical equipment is usually aircraft specific certified and
expensive. The 12V automotive equipment is much less expensive and I have
found to be as reliable or perhaps even more so.
