An Stovl Is An Acronym For Short Take Off And Vertical Landing. It Is An Ability Of Some Aircraft Like The F35B To Take Off From A Short Runway Or Take Off Verticalyy If It Doesn'T Have A Very Heavy Payload And Land Vertically. This Is Often Accomplished On Aircraft Carriers Through The Use Of "Ski-Jump" Runways, Instead Of The Conventional Catapult System. Stovl Use Tends To Allow Aircraft To Carry A Larger Payload As Compared To During The Vtol Use, While Still Only Requiring A Short Runway.
