Can You See Me Now?
Getting shot down isn’t the only threat faced by helicopter pilots flying in combat zones. In certain environments, the elements can be as dangerous as the enemy. In Iraq and Afghanistan, for instance, the thick dust created when a helicopter hovers close to the ground can cause even experienced pilots to crash. Degraded visuals sometimes lead to controlled flight into terrain (CFIT), an accident scenario in which an aircraft, under pilot control, is unintentionally flown into an obstacle.
