Which launch method corresponds to a vertical takeoff and landing capability?

• A. Vertical Takeoff and Landing (VTOL)
• B. Horizontal takeoff
• C. Catapult
• D. Hand launch

Answer: (A)

Vertical takeoff and landing means a drone can lift off straight up and land in the same way, without needing a runway. The method that provides this capability is VTOL, since VTOL describes aircraft designed to take off and land vertically. Drones with VTOL can hover and transition to forward flight after rising, which is what vertical takeoff and landing is all about. By contrast, horizontal takeoff requires enough forward speed and typically a runway; a catapult helps just to start flight for some aircraft and doesn’t inherently ensure vertical liftoff and landing; a hand launch is simply a manual throw and does not guarantee vertical lift. Therefore, VTOL is the best match for a vertical takeoff and landing capability.
