The Royal Jamaican Defence Force uses a modified King Air 350i for maritime surveillance. The actual aircraft includes a radome and a variety of sensors to allow it to monitor and protect the island nations waters.
This livery is based on the real aircraft T-11, however does no include any of the sensors and radar systems found on the real aircraft.
This is for the FSX default King Air 350, however it is also mostly compatible with Prepar3D v4. There are some known issues including the rendering of the spinner. See the Readme file for more details.
