This is the central section of a King Air B200 Main Instrument Panel that we supplied to a customer a year or so ago, complete with six of our dual radios, operational altitude alert, and an RNS530 unit.
Below is a better shot of the backlighting whilst the panel was still in the process of being populated ...
As with most of the parts that we supply, we fitted all of the hardware to the panel prior to sending it. This allows us to verify that everything fits correctly, and it also hopefully means that the installation once delivered will be a little more straight-forward.
