How Fast To Travel To Reach 90 000 Feet?

Idle descent in many jets is around 3,000 feet per minute until reaching 10,000 feet. There is a speed restriction of 250 knots below 10,000 feet, therefore the flight management computer will slow the aircraft to 250 knots and continue the descent at approximately 1,500 feet per minute.

Can planes fly at 80000 feet?

Most commercial aircraft are approved to fly at a maximum of around 42,000 feet . This maximum is also known as a ‘service ceiling. ‘ For example, for the double-decker Airbus A380 ‘superjumbo’ quadjet, this ceiling is 43,000 feet.

Can planes fly 70000 feet?

It provides day and night, high-altitude (70,000 feet, 21,300 meters) , all-weather intelligence gathering. Lockheed Corporation originally proposed it in 1953, it was approved in 1954, and its first test flight was in 1955. It was flown during the Cold War over the Soviet Union, China, Vietnam, and Cuba.

How high can a 747 fly?

Boeing 747

Lufthansa previously bragged that its 747-400 could reach the highest altitude in its fleet, reaching a max altitude of 44,947 ft (13,610 m) . Meanwhile, the modern 747-8, which is well deployed by the carrier, has a service ceiling of 43,100 ft (13,137 m).

What plane can fly the farthest?

The longest range jetliner in service is the Airbus A350 XWB Ultra Long Range , capable of flying up to 18,000 km (9,700 nmi). The A380 is capable of flying 14,800 km (8,000 nmi) with 544 passengers. The A350-900 can fly 15,000 km (8,100 nmi) with 325 passengers.

How fast do airliners descend?

Airliners can descend over 8,000 feet per minutes if needed. A descent from 35,000 feet at that rate would have you down to 11,000 feet in 3 minutes or less.

How fast is a 737 going when it lands?

The average landing speed for a Boeing 737-800 with flaps deployed is about 145 knots , but this can be higher depending on the plane’s weight. The number of flaps deployed can also vary due to crosswinds and wind shear. When landing without flaps, the speed on a 737-800 is more like 200 knots.

Why do planes fly at 35000 feet?

A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.

Why do private jets fly so high?

A private jet can fly at a height of up to 45 000 ft, though most cruise at 41 000 ft. This is generally higher than an airline flight and allows for a more direct route – out of the most congested area of the sky . A private jet pilot will choose the optimum cruising altitude depending on the distance of the journey.

Can plane fly over Mount Everest?

According Debapriyo, most commercial airlines avoid flying directly over the Himalayas . This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”

How high can jets fly?

In fact, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet , or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet above sea level.

Why do pilots breathe pure oxygen?

The pressure in a U-2 cockpit at typical mission altitude is equivalent to the atmosphere at 29,000 feet—as high as the summit of Mt. Everest. To cope , U-2 pilots breathe pure oxygen for an hour before their flight and wear a kind of pressurized spacesuit. Pre-breathing oxygen helps purge nitrogen from their bodies.

How fast can a U-2 plane fly?

With a cruise speed of 475 miles per hour and a wingspan of 103 feet, the Dragon Lady loves to fly. And when it comes to capturing data, flying at a high altitude is essential. The U-2 has demonstrated that the sweet spot for an ISR platform is 70,000 feet, and today’s U-2 engine, an F118 GE 101, gets the U-2 there.

Do pilots breathe 100% oxygen?

Today’s fighter pilots therefore operate in cabins pressurized according to a pressurization schedule,15 they breathe up to 100% oxygen ,15 and they wear and use pressure breathing equipment.

Can a 747 take-off with 2 engines?

There are only two engines in a 747. One can fly on a 757. Due to the time it would take to pick up enough speed to take off with just two engines, a 747 cannot take off with just two engines , but once it is in the air, it will keep going.

How high can helicopters fly?

Turbine-engined helicopters can reach around 25,000 feet . But the maximum height at which a helicopter can hover is much lower – a high performance helicopter like the Agusta A109E can hover at 10,400 feet.

How high can a 777 fly?

The Boeing 777 can fly as high as 43,100 feet . However, its normal cruising altitude is usually around 35,000-39,000 feet.

Why do planes do not fly over the Pacific?

Flying over the Pacific Ocean is avoided by most airlines for most flights because it usually doesn’t make sense to fly over it when shorter and safer routes exist . The Pacific Ocean is also more remote and less safe than the Indian and Atlantic Oceans to fly over, resulting in a higher chance of a plane crashing.

Why planes do not fly over Pacific Ocean?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes . Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

What’s the shortest flight in the world?

This, according to Guinness World Records, is the world’s shortest scheduled airline service, a trip that covers just 1.7 miles (2.7 kilometers) in less time than it takes most passenger airplanes to reach cruising altitude. On a good day, with favorable winds and light luggage, it takes 53 seconds.

How do pilots know when to descend?

Question: How do pilots know when to descend to land on the assigned runway at the correct speed? Answer: Pilots plan the descent based on the wind and air traffic flow . Working in partnership with air traffic control, the descent is executed allowing adequate distance to descend and line up with the proper runway.

How long does it take a plane to reach 30 000 feet?

Surely you know that airliners almost always fly at the same altitude, approximately 30,000 feet. After the take-off, it takes about 20 minutes to reach its cruising altitude.

How long does it take for a 737 to take off?

Answer: You are correct that a twin-engine jet will have an average takeoff run of 30 – 35 seconds , good observation. It will vary depending on the altitude of the airport, the weight of the airplane and the outside temperature.

How fast is a 747 going when it takes off?

What speed does a Boeing 747 take off at? A fully loaded Boeing 747 ‘Jumbo Jet’ on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph .

Can a 747 land on an aircraft carrier?

Large commercial aircraft like a Boeing 747 or an Airbus A-380 simply cannot fit on the deck without the wings clipping the island or other deck antennas , etc, not to mention requiring landing rolls of over 3000 ft even in the most extreme short field attempts.

How fast does a 727 go to take off?
