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
The average aircraft can go 600 miles per hour.
The proper landing speed of a huge aircraft is between 250 to 300 kmph. A good landing speed is 280kmph. Over speed in the landing then you may not be able to stop the plane in time.
This depends on the type of aeroplane. In the case of a VTOL jet the speed is actually zero.
About 260 km/h (161 miles/h)
It depends entirely on the speed of the jet.
Depending on the aircraft it ranges from 160 knots to 130 knots
2 mph
Current jet fighters average about 1,300 mph.
575 mph.
Average speed = Distance/Time Average speed = 5400/9 = 600 mph
Assuming a direct flight (aprox. 16000 km), and an average speed of mach .8 (average cruising speed for a commercial jet) the flight time would be somewhere around 17 hours give or take a few minutes for takeoff/landing.
