Maybe we can hope for a Sovereign+ either with Proline 21 or my favorite Garmin 5000.
I have to say that I`m very disappointed in the integration of the Honeywell Epic suite in the Sovereign. When being used to airline(Airbus), it feels very unfinished and not user friendly, like Cessna trying to play with the big boys but not having the knowhow with regards to working with Honeywell integrating the Epic suite.
Avionics aside, The Sovereign is a great little workhorse, docile and forgiving,
with a cargo hold an envy of all Hawker pilots I have met.
