## Why do planes do not fly over the Pacific?

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 is G limit in aircraft?

Aircraft have what’s typically referred to as a flight envelope. With in the envelope, say one where speed and load factor (g’s) are expressed on a plot, you’re ok if you remain within the boundary. Once you cross the boundary, the aircraft may stall, of fail to continue to perform adequately in some other manner.

## Can a 747 fly inverted?

Short answer yes any aircraft can be flown upside down if properly equipped. Long answer no. You need inverted fuel, and oil system which the 747 doesn’t have. You possibly could get it upside down but your engines would flame out immediately.

## How much G force can kill you?

There are isolated incidents of humans surviving abnormally high G-forces, most notably the Air Force officer John Stapp, who demonstrated a human can withstand 46.2 G’s. The experiment only went on a few seconds, but for an instant, his body had weighed over 7,700 pounds, according to NOVA.

## How many g’s do you feel in a car?

The normal range is -0.3g on braking to +0.3g on acceleration. This will cover about 80% of driving. A further 15% of driving is between -0.5g to +0.5g. On braking anything over -1.0g of deceleration is going to be a rather concerning experience for the driver – and potentially a crash.

## How many tons can a 747 carry?

139 tonnesThe airplane can carry a payload of 139 tonnes with a volume of (24462 ft³) in the main cargo deck. The 747-8F can carry 16% more revenue cargo volume and provides 17% more fuel-efficiency than its predecessor.

## Is 4 G force a lot?

We are most vulnerable to a force acting towards the feet, because this sends blood away from the brain. Five to 10 seconds at 4 to 5 g vertically typically leads to tunnel vision and then loss of consciousness. … People with the highest g tolerance are known as “g-monsters”.

## Can Airbus fly upside down?

The answer is flatly, no. Inverted flight requires a specific airfoil (wing shape) as well as specific lubrication systems for the engines. Transport category aircraft are not built to engage in inverted flight.

## Can planes fly at 50000 feet?

Currently, no passenger airplanes are “able” to fly at 50,000 feet or above. Because, at these altitudes, air density is very low, which wouldn’t sustain the heavy weight of the passenger aircrafts. Commercial airplanes have an Absolute Ceiling of 43000 feet.

## Do planes fly over Mt 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 fast does a 747 fly?

about 570 miles per hourThe top speed for a 747 is about 570 miles per hour (mph), and this flight topped out at 825 mph.

## Can a helicopter fly upside down?

In general, a helicopter may be able to fly upside down for short periods of time. However, inverted flight is never recommended for long-term use. Helicopters can fly upside down for a short amount of time when they are performing a loop. The things helicopters can do as opposed to airplanes are astonishing.

## How many Gs will knock you out?

It can be followed by convulsions and uncontrolled muscle movements. All in all, this can take perhaps 20 – 30 seconds, though it can vary widely.” In an untrained adult, as few as 3 G’s can be enough to deprive the brain of oxygen, Fan said.

## How many G’s does a commercial plane pull?

Very little G-force is experienced by the passengers (in excess of the standard 1 G all passengers feel is straight down). The G-force experienced by a passenger at the most in normal flight is about 1.2 – 1.3 Gs, which is seldom noticed or felt when the aircraft is also moving around.

## Can a passenger plane fly upside down?

The answer is yes for a “little” bit! Unlike military fighters, commercial planes do not have the engine power for sustained inverted flight and rely on lift from the wings. … Commercial airliners are only tested and certified for upright flight.” However, one Boeing aircraft has flown upside down – twice!

## How fast can a human move without dying?

And the answer is roughly 45G’s. And this would be equal to around 0.06 seconds to 60 mph. Air Force officer John Stapp survived 46.2G’s.

## Can a helicopter fly in a tunnel?

Helicopters can (and have) flown into and through wide buildings like hangars and abandoned factories. Helicopters almost certainly cannot fly for any length of time in narrow passages like tunnels.

## Can a 4 engine plane fly with one engine?

Yes it can. A twin-engine aircraft can fly perfectly well on one engine. In fact, it can even continue the take-off and then safely land with just one engine. Losing an engine in flight is not usually a particularly serious problem and the pilots are given extensive training to deal with such a situation.

## How many G’s is 25000 mph?

In order for them to accelerate to light speed from 25,000mph, and achieve no more than 10 g’s, a force that is still virtually unbearable, it would take approximately 3,058,992 seconds, 50,983 hrs, 2,124 days, or 5.8 years, then doubling of course to allow for the the equally powerful negative G-forces you’d achieve …

## What happens if a plane goes too high?

When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …

## Can a plane flip over in turbulence?

For all intents and purposes, a plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket. Conditions might be annoying and uncomfortable, but the plane is not going to crash.

## How many G’s is a car’s acceleration?

So, 0-60 mph in 10 seconds will expose you to 0.27g. Barely over a quarter of normal Earth gravity. To equal 1g of acceleration, a car would need to get to 60 in 2.74 seconds, roughly.

## Can 747 DO loops?

It’s not possible for a 747 to do a (inside) loop. … if you try to loop a 747, you’ll overstress the wings on the way up, all sorts of aircraft systems will have a problem in the low-g section just over the top, and then you’ll overstress and perhaps overspeed the wings on the way down.

## What is the biggest plane in the world?

Antonov An-225 MriyaAntonov An-225 Mriya — the largest aircraft by weight, length and wingspan. The six-engined Antonov An-225 is literally in a category of its own, holding the titles of both the heaviest aircraft ever built and the largest wingspan of an aircraft currently in service. In fact, only one An-225 has ever been built.

## How many G’s can a human take?

5 g0A typical person can handle about 5 g0 (49 m/s2) (meaning some people might pass out when riding a higher-g roller coaster, which in some cases exceeds this point) before losing consciousness, but through the combination of special g-suits and efforts to strain muscles—both of which act to force blood back into the …

## How does G Force feel?

If you’ve ever been on a roller coaster, you know what a quick spike in G-force feels like. But the sensation of intense pressure is greater and longer in duration for someone strapped into the cockpit of a fighter jet, a vehicle which can “pull” up to nine times the force of gravity.

## Can you fly upside down and not know it?

Airliners are not designed to fly upside down. … The short answer to the question is a plane cannot go into inverted flight without the crew noticing. They or he – the pilot – would know something was seriously wrong.

## Can you fly a 737 upside down?

A 737-700 will fly upside down, but it will lose altitude pretty fast, and unless you drop the gear the airspeed will increase pretty quickly.
