A typical landing speed for a 747 is around 145-160 knots, which is equivalent to 166-184 miles per hour.
The weight of the aircraft affects the landing speed of a 747. The heavier the aircraft, the faster it needs to fly to generate enough lift to stay in the air. So a fully loaded 747 will have a higher landing speed than an empty one. The maximum landing weight for a 747 is 285,000 kilograms or 630,000 pounds.
The wind conditions also affect the landing speed of a 747. The wind can either help or hinder the aircraft’s speed and direction. A headwind is a wind that blows against the direction of flight, reducing the ground speed of the aircraft. A tailwind is a wind that blows in the same direction as the flight, increasing the ground speed of the aircraft. A crosswind is a wind that blows across the runway, making it harder to align and control the aircraft. To compensate for these effects, pilots add or subtract some speed to their approach speed, depending on the strength and direction of the wind.
