Can a 737 go supersonic?
Can a 737 go supersonic? Mach 0.7 at 40,000ft is 407 knots. The speed of sound, which of course changes with altitude (well technically temperature), travels at 573 knots at 40,000ft. For a 737 to reach the speed of sound at 40,000ft, it would need to be cruising at Mach 1.0, which is completely unrealistic for a normal passenger 737.
How fast is a 737 going when it touches down?
For an average-sized commercial jetliner with typical fuel and payload, the takeoff speed is around 130-160 knots, or about 150 to 200 miles per hour. The landing speed is more or less the same, usually a few knots slower. With a very common 737-800 the landing speed is about 180-200 knots.
Can a 777 go supersonic?
Why does the Boeing 777 sound like a four engine aircraft when it flies over? No, it is not supersonic. The speed of sound (Mach 1) is approximately 767 mph or 661 knots, so the Boeing 777 flying at 660 knots would be subsonic. However, that's still a very impressive speed!
How much did a Concorde ticket cost?
Such speed didn't come cheap, though: A transatlantic flight required the high-maintenance aircraft to gulp jet fuel at the rate of one ton per seat, and the average round-trip price was $12,000.
What is the highest Mach ever reached by a human?
Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.
Why was the Concorde banned?
The Concorde's retirement was due to a number of factors. The supersonic aircraft was noisy and extremely expensive to operate, which restricted flight availability. The operating costs required fare pricing that was prohibitively high for many consumers.
Can a 747 reach Mach 1?
Original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 0.99. In addition, Boeing knows one case in which a 747 operated by Evergreen International made an emergency descent at speeds that exceeded Mach 1.
Why is sonic boom illegal?
Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.
Is it illegal to go supersonic?
Current rules prohibit commercial airplanes from flying at supersonic speeds over land because of the noise levels associated with sonic booms and the negative impacts to humans and animals.
What is the 1100 mph plane?
Spike Aerospace, founded in 2013 Max Kachoria of NASA, built an 18-passenger supersonic jet with low-sonic boom, fuel efficiency, speeds up to 1,100 mph, and flight times slashed in half. Their current model is the S-512 which can get passengers to cities in a moment's notice: NYC to London: 3 hours.
What is the fastest plane in the world?
The North American X-15 may be the fastest plane in the world, with speeds at 4,520 mph and Mach 5.93. It's an experimental aircraft used and powered by NASA and USAF.
What is the fastest a 747 has ever flown?
Aided by a more powerful jet stream than usual, this rapid journey saw the 747 reach a top speed of 825 mph. Photo: Markus Mainka I Shutterstock. Popular Mechanics reports that the reason for it being so powerful on this occasion was a 'bomb cyclone' near Greenland.
Can a pilot feel a sonic boom?
And the jet pilots don't feel a sonic boom from the cockpit, just as passengers on a boat don't feel the effects of the wake behind them, she added.
