ZFW, ground power & local variables

[smashingjonor]

Hello,

It would be very useful to be able to input zero fuel weight through local variables as this would make it possible for 3rd party software other than SimBrief to automatically input zero fuel weight between flights.

Another thing would be to be able to request ground power through a local variable and to also be able to connect ground power without the GPU cart.
Quite often IRL, ground power is provided without a GPU cart so always hearing the GPU breaks the immersion.

The ground power variable could take the following input:
1 = Connect ground power with GPU cart.
2 = Connect ground power without GPU cart.
3 = Disconnect ground power

It would also be useful to be able to manage the chocks with a local variable.
