A Boeing 747-8 landing with 85% of its payload and 30% of its fuel, weighs 92% (8F) or 98% (8i) of its Maximum Landing Weight (MLW). The FAA/EASA Minimum runway length requirements for MLW landings are 7,500ft (~2,300m) for the 747-8F, and 6,750ft (~2,000m) for the 747-8i.

A runway of at least 6,000 ft (1,829 m) in length is usually adequate for aircraft weights below approximately 200,000 lb (90,718 kg). Larger aircraft including widebodies will usually require at least 8,000 ft (2,438 m) at sea level and somewhat more at higher altitude airports.
The chart notes that if a Boeing 747-400 had an operational landing weight of 475,000 lbs (215,456 kg) and wanted to land at a runway located at sea level, then the suggested runway length would be a little over 1,500 meters, or roughly 5,000 feet.
What jets can land on a 5000 foot runway? If the runway is at sea level and the runway length is 5,000 feet then turbo props, light jets, mid-size jet and heavy jets have the performance. It's important to note that for every 2,000 feet of elevation, you need an increase of 1,000 feet in runway length.
Crashes that destroy the airframe are the most obvious answer, but minor, low-speed incidents on the ground can also bring a plane's career to an end. This was the case for a SaudiaBoeing 747-300, which taxied into a ditch in Kuala Lumpur in 2001.
Can a 747 land on a 7000 foot runway? A 747 requires a 7400 foot runway at a normal operating weight, so if it were particularly light, it could operate on a 7000 foot runway.
A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
Different airplanes have different maximum altitudes, depending on their construction. For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 747 45,000 feet (13,700m).
At cruising altitude, most commercial airplanes fly at a speed of roughly 500 to 600 mph. When landing, however, they must reduce their speed. A typical 747, for instance, has a landing speed of about 160 to 170 mph. And upon touching the runway, airplanes must quickly brake until they come to a complete stop.
The Boeing 747 is considered to have the longest takeoff distance of the more common aircraft types and has set the standard for runway lengths of larger international airports. At sea level, 3,200 m (10,500 ft) can be considered an adequate length to land virtually any aircraft.
4 November 1993: China Airlines Flight 605, a Boeing 747-409, ended up in water after it overran runway 13 at Kai Tak International Airport on landing during a typhoon with wind gusting to gale force. All of the 396 occupants donned life-vests, boarded the eight slide/rafts and no fatalities resulted.
Yes, in theory, an 400,000 kg airplane like a 747 could be fitted with floats capable of displacing the 400 cubic meters of water required to keep it afloat, albeit with a decrease in performance.
The letters, differentiate between left (L), right (R), or center (C) parallel runways, as applicable: For two parallel runways “L” “R.”For three parallel runways “L” “C” “R.”
Shigatse Peace Airport, China (runway length: 5,000m)Shigatse Peace Airport (RKZ), a dual-use military and civilian airport in Shigatse, Tibet hosts the longest runway in the world. The new runway (09/27) stretches 5,000m (16,404 ft) long with a 60-meter asphalt overrun at each end.
