In one aspect, a system for safely landing a vertical takeoff-and-landing (VTOL) aircraft in the air onto a landing pad on the ground is disclosed. The system can begin by determining an estimated location of the landing pad with a first accuracy. The system then reduces a height of the VTOL aircraft to a first level above the ground while approaching the estimated location of the landing pad. Next, the system determines an updated location of the landing pad with a second accuracy. The system subsequently reduces the height of the VTOL aircraft to a second level above the ground while approaching the updated location of the landing pad. Next, the system aligns a center point of the VTOL aircraft with a center location of the landing pad. Finally, the system lands the VTOL aircraft onto the landing pad by directly lowering the VTOL aircraft onto the landing pad.
