Quick Answer: What Is The Stall Speed Of A 747?

What is the landing speed of a 747?

A typical fully loaded 747 would be landing at around 25,0000kgs.

The landing speed would be around 145kts-150kts (166mph-172mph) depending on the landing flap setting selected.

The greater the flap setting the lower the speed..

How far can a 777 glide without power?

This means that for every kilometer fallen, the 777 will travel 15 kilometers forward. So if at an altitude of 40,000 feet, or roughly 12 kilometers, you’ll glide for up to 180 km. If you’re somewhere over land, you’ll probably have enough time to assess your options and maybe even find an airport to land at.

What is the fastest jet in the world?

Lockheed SR-71 BlackbirdThe Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.

What speed do planes land at?

Big commercial airplanes generally fly in the 550-580 MPH range, but their landing and taking-off speeds are naturally going to be different. Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH.

Why do pilots say v1 rotate?

Question: What does it mean when pilots say “rotate” when taking off? Answer: There are three speeds pilots use during takeoff. The first one is the decision speed at which stopping is no longer possible and the airplane is committed to fly. … It can be said that V1 is the “commit to fly” speed.

What is the oldest 747 still flying?

The oldest 747 still flying ordinary punters is owned by Iran’s Mahan Air. It first flew in 1986 and has been on Mahan’s books since 2007. The majority of BA’s active jumbos are far newer. The oldest, G-BNLY, was delivered in 1993; the newest, G-BYGG, in 1999.

How far can a Boeing 777 fly on one engine?

The Boeing 777 is designed to fly for at least 3 hours on one engine for a distance up to 1320 nautical miles or 2110 kilometers.

Which is faster 747 or 777?

— submitted by reader James Kriplean, Knoxville, Tenn. Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach . … A 777 engine may be equal to two 747 engines, but the wing is not designed to take such a large engine in one place.

Can an Airbus a380 fly on one engine?

Under Federal Aviation Regulations the A380 is designed to be flown on two engines only in extreme cases. But a single-engine would not supply enough power to keep the aircraft level.

Why do commercial airliners fly at 35000 feet?

The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.

What is the stall speed of a 737?

It depends on a lot of conditions including weight and airplane configuration. The stalling speed in a landing configuration for a 737 is probably around 108 knots. The stalling speed in a clean configuration is around 128 knots. The landing speed is about 140 knots.

What is the stall speed of a Boeing 777?

The Boeing 777-200ER take off or rotate speed (VR) typically varies between 130 – 160 knots (roughly 120-180 mph) depending on the weight of the aircraft. At a typical take-off weight of around 230,000 kgs, the take off speed would be approximately 145 kts which is approximately 165 mph.

How high can a 777 fly?

43,100 feetOn a Boeing 777, the maximum service ceiling (altitude at which the maximum rate of climb is reduced to around 100 feet/min) or aircraft*s certification altitude is 43,100 feet.

What’s the slowest a plane can fly?

Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.

What is the average cruising speed of a 747?

0.84 to 0.88The Boeing 747 is a large, wide-body (two-aisle) airliner with four wing-mounted engines. Its wings have a high sweep angle of 37.5 degrees for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant.

Why was the 747 discontinued?

Boeing to end 747 production due to coronavirus, marking end of era – Business Insider.

Are 747 still being built?

US airplane manufacturer Boeing will cease production of its 747 jumbo jet in 2022, the company announced on Wednesday, retiring the iconic passenger aircraft after over 50 years of service amid a coronavirus-induced crisis in the aviation industry.

Why is 747 retired?

The reason for BA’s decision is that giant, four-engine aircraft like the 747 are too expensive to operate. Many other airlines have made the same choice. First of all, there is maintenance. Keeping four engines running to the required standards is more expensive than modern twin-jets.
