The engine design is for a conventional, non-aerobatic, fixed wing tractor or pusher
type configuration with the oil return port in the optimum position (see section 13.5).
With this consideration the engine is properly lubricated in all flight profiles.
The resulting bank angle b (depending on acceleration/deceleration) may never
exceed the max. bank angle.
◆ NOTE: Pitch or role angle α is not equal with β, except stabilized condition
(without acceleration).
