Squawks on the part they're about, the load where it sits, takeoff on a real runway and glide over the real ground. The same 3D views the app opens for every tail with a model.

Squawks on the airframe

Every squawk pins to the part it's about: open in olive, grounding in red. The mechanic, the renter and the next pilot see the same airplane.
