# How far up can an airplane go?

Contents

While most commercial airplanes fly at 30,000 to 36,000 feet, their respective certified maximum altitude is typically slighter higher. Most commercial airplanes have a certified maximum altitude of about 40,000 to 45,000 feet.

## What is the highest altitude a plane can fly?

Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet. The highest business jet flying today reaches 51,000 feet.

## What happens if a plane flies 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 planes fly at 50000 feet?

Answer: Every airplane has a certified maximum altitude. … A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence.

## Can a plane fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

## Why do planes not fly directly over the 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 happens if a plane window breaks?

Basically, the air pressure inside the cabin is higher than it is outside of the plane to enable the people onboard to breathe normally. That’s why, if a window happens to break, the air inside would escape at high speeds, taking small objects like phones or magazines (or sometimes larger things, like people) with it.

## How long would it take to fly in a 747 to the moon?

A 747 airplane normally flies at about 400 miles per hour. The moon is about 250,000 miles away. So if we divide 250,000 by 400, we find that the plane would take 625 hours — or 26 days — to fly to the moon! Boy that would be a looong trip!

## Why do planes fly at 40000 feet?

1. Many flights are not as full as they were, so they are lighter and can fly at higher altitudes, which are more fuel-efficient. … Many business jets can fly higher, routinely cruising in the high 40,000s. The maximum altitude for many business jets is 51,000 feet.

## How high can a 777 fly?

#Update – Thank you for your answers. The Boeing 777 can fly as high as 43,100 feet. However, its normal cruising altitude is usually around 35,000-39,000 feet.

## How cold is it at 40000 feet?

After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit.

## Why do private jets fly at higher altitudes?

One of the reasons private jets fly at a higher altitude than commercial jets is to avoid heavy air traffic. … Private jets lack the high-tech sensors and controls of commercial jets, so pilots operating them typically fly at a higher altitude where there’s less traffic.

## Can an airplane stop in the air?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.

## Can a jet reach space?

Planes can and have flown into space for over 50 years – though not the kind you see at the airport. That’s because conventional planes need air for both propulsion and lift, and space is essentially a vacuum.

## Can planes fly in rain?

Flying in Heavy Rain

Rain doesn’t usually affect a flight much. Combining with hefty winds causes extra challenges to flight planning. The combo can even cause a change of route or a delay if the conditions are extreme. But generally speaking, airplanes are well-equipped to deal with a bit of the wet stuff!
