# Quick Answer: What Is The Maximum Height A Flight Can Fly?

## 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.” ….

## Why do planes 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.

## Can a plane accidentally fly into space?

If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion. The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion.

## How many planes are flying right now?

Right now (midday, 30 March), according to FlightRadar24, there are around 5,000 planes flying in the sky around the world.

## Can a plane fly at 60000 feet?

Question: What is the highest altitude an airplane 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.

## Why is it better to fly higher?

The main reason for flying high is to benefit from the thinner air, which allows a much higher true airspeed and groundspeed for the same aerodynamic speed the airplane “feels”. That gets you to your destination a lot faster and for a fraction of the fuel you’d burn if you’d fly low.

## Can planes fly at 40000 feet?

Modern airliners are usually built with the ability to function when flying over 40,000 feet. Despite these capabilities, pilots don’t usually hit these levels when there are passengers are on board. … However, travelers are more likely find themselves in the air at a cruising altitude of around 35,000 feet.

## How high can a 747 fly?

35,105 ftEvery 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.

## Do longer flights fly higher?

Long distance flights don’t fly any higher or lower than say any flight over say 300nm.

## Can a plane fly over Mount Everest?

Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … 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.”

## What is the safest aircraft?

Although The US manufactured Boeing 737 MAX was the fastest selling aircraft, it has been grounded following the Ethiopian Airlines crash tragedy and a series of problems in other flights. Boeing 717, 787, 747-800 and the Dreamliner 787 have been deemed as safest for their fatality free flight records.

## Can a plane fly with one wing?

No, an airplane cannot fly with only one wing. In order for a plane to stay stable in air, it has to maintain balance. With only one wing, the weight is shifted to one side of the plane.

## How fast do airplanes go?

500 knotsJust how quickly do passenger aircraft fly? Commercial jet aircraft cruise at about 400 – 500 knots (460 – 575 mph / 740 – 930 kph) – read more to understand the background behind it. Speed can get a bit confusing when talking about an object moving through the air.

## Can a jet fly through a tornado?

Flying through a tornado could destroy an airplane; pilots avoid all thunderstorms — particularly those producing tornadoes — by a wide margin.

## Why do planes 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.

## Has anyone been lost in space?

As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.

## What level of atmosphere do planes fly in?

stratosphereCommercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.

## 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.
