It's about 170 mph depending on weight.
There are many different types of 747. The average landing speed would be 150 knots for a 747. It can be anywhere from about 120 to 180 knots depending on gross weight
140knots
You can land a 747 slower tha most jsts - 140 knots is ok for a normal landing
The landing speed is 155 knots or more generally from 150 to 160 knots, depending on weight and wind conditions.
The landing speed of an airplane can vary depending on factors such as the type of aircraft, its weight, weather conditions, and runway length. On average, commercial airplanes typically land at speeds ranging from 130 to 160 knots (150 to 185 mph). The pilot will adjust the speed and approach angle to ensure a safe landing.
150 knots
Depends on the speed of the airplane and the landing delays.
747
All commercial (heavy) aircraft have a range of landing speeds which vary according to landing weight and configuration (flap setting). The normal range for the 747 for various weights and flap settings is around 130 to 160 kts.
The stall speed of a Boeing 747 heavy (747-400 or -8 model) is around 155-165 knots indicated airspeed (KIAS) at typical landing weight. This speed can vary based on factors such as weight, configuration, and atmospheric conditions.
An approach (landing) speed is determined by the type of plane, weight, weather and the condition of the runway. A heavy 747-400 might have a landing speed of 160 KIAS (knots indicated air speed) or about 185 mph.
According to Boeing's website, "the 747-400ER is now the largest and fastest commercial airplane in the sky - cruising at Mach 0.85, or 85 percent of the speed of sound."
