The old update() method relied only on switches positions. Now the switches and system status are used to define the bus voltages, contact connections, relays, and more.
EICAS will now show the voltage of the emergency bus.
Batteries drain out or are recharged.
Avionics Master switch has been set to ON at all births.
Engine:
Engine starting/shutting down will now take into consideration the switches positions, whether the starter is on, the ignition status, the power supply and the engine rpm.
It's now possible to execute dry startups, startups with PMU in manual and automatic reignition.
The engine can now start with main pumps in off (mechanical pump mode).
Using the starter now heavily drains the battery if no external power is supplied. This should be enough for one startup in flight, or one in the ground.
Added the ENG MAN alarm.
Brakes:
The brake light color is now green.
The parking brake will now turn on only if there is enough pressure in the emergency brake accumulator.
The accumulator will recharge when the compressor is running.
Added the EMER BRK alarm.
Flaps:
Now they default to DN when birth=GROUND_HOT (You take off with flaps in DN).
