Dis one first develop to help launch STOVL aircraft take off at far higher weights pass wetin fit happen with vertical or rolling takeoff on flat decks. Originally developed by di Royal Navy, e don dey adopted by many navies for smaller carriers. Ski-jump ramp dey work by converting some of di forward rolling movement of di aircraft into vertical velocity and sometimes dem dey combine am with di aiming of jet thrust partly downwards. Dis one allow heavily loaded and fueled aircraft few more precious seconds to attain sufficient air velocity and lift to sustain normal flight. Without ski-jump ramp to launch fully loaded and fueled aircraft like di Harrier no go fit happen on smaller flat deck ship before e go either stall out or crash directly into di sea.
