Why Do Commercial Airliners Fly At 35000 Feet?

What is the maximum altitude of a commercial airplane?

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..

At what altitude can a human not breathe?

An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us. By comparison, the summit of Mount Everest (the Earth’s highest mountain) lies at 29,141 feet.

What happens if a helicopter flies too high?

What Happens If a Helicopter Flies Too High? As the helicopter ascends, the air begins to thin. With thinner air, the main rotor becomes less efficient. The higher the helicopter flies, the slower it ascends due to the reduced power generated by the rotor.

How high can a JetPack fly?

15,000 feetAnd JetPack Aviation, based in the San Fernando Valley area of Los Angeles, invented what it calls “the world’s only JetPack,” which can reach up to 15,000 feet in altitude and operate for about 10 minutes.

Why do jets fly at high altitudes?

The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.

Can you breathe at 35000 feet?

Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing.

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. … Whether a commercial airline is flying from the United States to Asia or elsewhere, it will have the fastest and most fuel-efficient flight by performing a curved rout.

Do Planes 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 longest non stop flight?

Singapore Airlines currently operates the longest flight in the world, a whopping 9,534-mile nonstop from Newark to the Lion City.

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.” …

What is the temperature at 35000 feet?

At 35,000 feet the air temperature is about -54C.

Why do commercial planes fly at 35000 feet?

The biggest reason for this altitude lies with fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak. Spending less on fuel is also great for airlines, for obvious reasons.
