[SU13] Please explain new short hand electrical in Systems.cfg

The DV20 now has

[ELECTRICAL]
flap_motor = 0, 5 , 17.0
gear_motor = 0, 5 , 17.0
autopilot = 0, 5 , 17.0
avionics_bus = 0, 5 , 17.0
avionics = 1, 5 , 17.0
pitot_heat = 0, 2 , 17.0 ; Scalar on heat effectiveness, 0 = not available
additional_system = 0, 2 , 17.0
marker_beacon = 1, 2 , 17.0
gear_warning = 0, 2 , 17.0
fuel_pump = 0, 5 , 17.0
starter1 = 0, 20, 17.0
light_nav = 0, 5 , 17.0
light_beacon = 0, 5 , 17.0
light_landing = 0, 5 , 17.0
light_taxi = 0, 5 , 17.0
light_strobe = 0, 5 , 17.0
light_panel = 0, 5 , 17.0
directional_gyro = 0, 5 , 17.0

Is this a new way? How compatable is it with the existing [ELECTRICAL], can we mix?

Hello! That’s not a “new” shorthand, but actually a very old way of doing electrics that was deprecated some years ago! Some of the simpler aircraft (like the one mentioned) have not been updated to the new system and still make use of those legacy parameters. You should ignore these for MSFS2020 and use the documented systems instead.
