Web10 de abr. de 2024 · “Ground effect” is the effect of a “cushion” of air, which forms close to the ground under a hovering helicopter, and helps to hold it up. This increases aerodynamic performance, and the result is that the helicopter can hover with less power. But it only works when the helicopter is around 1 – 1.5 rotor lengths above the ground. … WebHá 1 dia · Open Steam. Click on Library to see your games list.
