What Is A Black Hole Approach?

A black hole is considered a place where gravitational effects are so strong that even light may escape. In aviation, a black hole approach is a term for landing during the dark night when even the moon and stars are not visible in the sky. A black hole approach is an illusion that can happen while flying over water on a very dark night. As the term suggests, it is an approach at night where nothing is visible between the aircraft and where it intends to land.
