Approx. 900 km/h or 560 mph at cruising altitude.
The maximum certificated altitude for the 747 is 45,100 feet.
A normal commercial jet can cruise at a speed of mach 0.85 or about 570 miles
585 mph
A cr 85 does 75 i have had 65 cruising
The maximum speed is 0.92 mach.
Max speed is 0.92 mach.
About 180-200 miles per hour.
About 180-200 miles per hour.
At altitude the Eurofighter flies at about 1,320 mph.
Because tha altitude influences the air pressure, and the air pressure influences the wind resistance. The higher the plane is the faster it'll go for the same amount of throttle.
Cruising speed is 585 mph. The max speed for a 747-8 is 614mph, or 988km/h.Maximum speed = 0.92 machI recently watched a YouTubevideo of a Boeing 747 that reached a ground speed of 744 MPH (1196 km/hr). This is the highest speed that I know of that a 747 has ever flew. Here's the link to the video if you want to watch it. http://www.youtube.comwatch?v=AHrsYKTnGAUIt's titled "Boeing 747 Fastest Speed Commercial Flight".0.85 Mach567 mph (913 km/h)AnswerThe Boeing 747 cruises at around 0.85 Mach, but in answer to how fast "can" one go, the answer is that Vmo/Mmo (maximum operating speed/mach) for the earlier versions is 0.89 Mach and for the 747-400 it's 0.92 Mach.
