  1. No condition levers on the J all done by the fadec. Just an on/off switch. Turn it off as it shuts down the prop will move towards feather as i said earlier then the prop aux feather pumps or t handles are used to move it to full feather position .

  2. The J prop moves towards feather on shutdown due to counter weights and lack of oil pressure. The prop blades are normally fully feathered on the ground to stop them windmilling in the breeze as the J has a free turbine design. The RAF aircraft are fitted with a prop brake but we still feather just in case.
