The concept with a switched power
supply makes the flight deck really dark as long as
the battery switch is in its 'OFF' position.
With this solution the display units are really
switched off with the cockpit in the COLD state and
not only blanked by software. It
also supports the approach of a 'green flight deck'
because as long as the battery switch is 'OFF' the
power consumption of the flight deck is quite low.

simplification the neutral line wiring and
the protective earth is not shown in the circuit
diagram.

Computer Rack
The power supply of the computer rack is much easier.
The rack has its own 16A automatic circuit breaker
(L2)
in the house mains distributor. The challenge was to avoid a trip of the circuit breaker
with switch in, because the inrush current of 4
computers and data projector at the same time can
become
quite high. The solutions was a switch-in
suppression circuit, as shown in the picture below.
