The AvWeb article says regarding payload:
Cirrus expects to get approval for a two-step change. Step one is simply a paperwork change to the SR20’s documentation, flight manual and placards. A second, larger gain will involve physical changes to the airplane. Cirrus will make the change on its production line and field retrofits will be available.
Does anyone have an idea when Cirrus will start making the necessary physical changes to the SR20 to increase payload?
