Hi there!
Is it possible to turn the panel lights off at night while in flight?  I haven't found a way to turn them off only dim them via the glare shield knob.

Not yet, I hope that CS will add this feature.

Is it possible to see the wingtip strobes via the passenger view?

Not yet...

Is the TCAS gonna be implemented with the SB4 transponder? Soit goes on when TCAS is engaged.

I think that CS will add this on the next service pack

The RAT cannot be stowed once deployed in flight correct?

It's like the reality.
