A brown-out can sometimes occur when landing in dusty terrain. The downwash of the rotor blades can cause a dangerous cloud of dust to rise and obstruct the pilot's vision. This can make it unsafe to land, requiring the pilot to abort the landing and ascend until they have adequate visibility. | ACE Training Centre | Facebook
