It depends on the airplane. A Boeing 747 needs to go 160 knots before you can take off in it; a Cessna 172 needs to go 55 knots to take off.
The Boeing 747's takeoff speed if 156knts or 180mph.Take off speed for 747-400 fully loaded is 155-160 knots or almost 300 km/h or 180 mph. About the speed of of an F1 racer down a long straight.The standard speed for a Boeing 747 to take off is at about 120 miles per hour.Take off speed for 747-400 fully loaded is 155-160 knots or almost 300 km/h or 180 mph. About the speed of of an F1 racer down a long straight.
speeds depend on the weather condition and how long the runway is but usally a 747 takes off at 150-154 knots.
to gain speed for take off
It depends on the airplane. A 747 is a lot louder than a King Air, which is louder than a Piper Warrior. But a 747 is quieter than an F/A-18 taking off from an aircraft carrier.
About 160 Knots
each plane has a set take off speed , flap position and weight for take off
It then produces lift due to wing configuration and can take off
The lift off speed of a Boeing 747 can vary depending on factors such as weight, runway length, and weather conditions. On average, a Boeing 747 typically takes off at a speed between 160 to 180 knots (184 to 207 mph).
The takeoff speed of a Boeing 747 can vary depending on factors such as weight, runway length, and weather conditions. However, generally speaking, the takeoff speed of a Boeing 747 is around 180-200 knots (207-230 mph).
The answer depends upon several factors, but a fully loaded 747-400 taking off from a sea level airport with a temperature of 15 C would be taking off with a speen of about 185 knots.
Depends on the aircraft, can be anywhere from 40 to 160 mph.
