Definition
The term, in context
AI-assisted draft · approved dataset
The Joby S4 is an electric vertical takeoff and landing aircraft that uses multiple electrically driven rotors to lift off and land like a helicopter, then tilts those rotors forward to fly like a fixed-wing airplane for cruise. This hybrid lift-and-cruise configuration is designed to combine helicopter-like operational flexibility with the speed and range efficiency of winged flight.
