Recently, several of our customers who upgraded early for ADS-B to the DO-260A standard have received letters from the FAA, alerting them to the fact that they are not in compliance with the ADS-B mandate.
Working with the Duncan Aviation Aircraft Design team is a remarkable experience. The designer interviews the aircraft owner to get an initial feel for their preferences and tastes. They then bring a suitcase full of pre-selected sample materials to an in-person meeting to further dialog and fine-tune the design. The next step is often the development of a realistic rendering so the client can visually see their future refurbished cabin.
