What is the stall speed of a 747?
Now plug in the numbers: Minimum weight for a 747–400 is 254,500 kg, and the same source gives the stall speed in landing configuration at 280 tons with 138 knots or 71 m/s.
How Slow Can a commercial plane fly?
These planes often have an upper speed limit of about 40 mph.
Can a 747 fly supersonic?
The 747-100 is designed to withstand a top speed of Mach 0.92 – nine-tenths the speed of sound, or more than 500 miles per hour at that altitude.
What is the slowest plane in the world?
The slowest powered plane ever flown (even if it was human powered) was the MacCready Gossamer Albatross. And it was very slow – topping out at 18mph.
What is the most dangerous part of a flight?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
At what speed does a plane take off?
Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.
Do planes fly slower to save fuel?
According to Drela, today’s airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds. (Cars also become more efficient at slower speeds on highways.)
What is the easiest jet to fly?
The Top 6 Easiest Planes to Fly
- J-3 Piper Cub.
- Diamond DA40 Star.
- Cessna 152.
- Piper Pa28.
- Cirrus SR22.
- Cessna 172 Skyhawk.
What is the biggest plane in the world?
By the numbers, the Stratolaunch — code name “Roc” — is the largest plane ever built. Its wings measure 385 feet across, longer than a professional football field. Its twin fuselages are 238 feet long, while its tail height is 50 feet.
Did the 747 break the sound barrier?
As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.
How high can a 747 go?
Every flight has its own ideal cruising altitude. This is the sweet spot where plane fly as fast as possible, but burn the least amount of fuel. A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. The Airbus A380 can even fly at 43,097 ft. 5 дней назад
Can planes fly faster than the speed of sound?
A supersonic aircraft is an aircraft able to fly faster than the speed of sound (Mach number 1). The aerodynamics of supersonic flight is called compressible flow because of the compression associated with the shock waves or “sonic boom” created by any object travelling faster than sound.
What is the safest plane in the world?

- Qantas. A Qantas Airbus A380.
- Qatar Airways. A Qatar Airways Boeing 777-200LR.
- Air New Zealand. An Air New Zealand Boeing 777-200.

What is the fastest plane in history?
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.
What country has the fastest fighter jet?
The fastest fighter still in service today is the Soviet-built MiG-25. Mikoyan designed this fighter to be a pure interceptor aircraft. As a result, the Foxbat can sustain a cruising speed of Mach 2.8 and kick it into overdrive with a top speed of 3.2 – not a bad technology for an aircraft that first took off in 1964.
