Answer to the question:
FDS and all white liveries.
And Airbus’/Boeing’s factory livery.
I consider those corporate jets
Glad to know that I’ve been using it right then thanks a lot.
BBJ could be also.
For “Factory” liveries I use “Test Flight”
Cessna Citation is also a corporate jet.
I usually use my own callsign for the Cessna Citation X.
I thought it was for Corporate Air (an airline operating for FedEx)…
