Frequent question: Why do pilots prefer to fly at 36000 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.

Why do planes fly at 36000?

Since 36,000 feet is a further 7000 feet higher than the peak of Mount Everest, the air up there is pretty thin. That allows the aircraft to travel faster while using less fuel. Flying at this height also lessens the chance of a plane coming into contact with something else.

Why do commercial 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. … Also, oxygen starts to become scarce, making it difficult for fuel engine systems to work.

What is the advantage of aircraft flying at a higher altitude?

Climbing to higher altitudes can avoid the traffic of lower altitudes and translate to less drag, as well as less turbulence. That means decreased consumption of fuel, and, depending on the jet stream, can also mean the availability of tailwinds.

Why do jet planes fly at 30000 feet?

Most often, commercial airplanes fly anywhere between 30,000 and 42,000 feet in the air, which equals five to seven miles high. Why? The main reason is fuel efficiency. Put simply, airplanes use less fuel in higher altitudes where the air is thinner, increasing the efficiency and saving them money at the same time.

Why do planes fly at 34000 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.

Can you see a plane at 30000 feet?

Here is the theoretical distance you can see from a plane at different altitudes, given perfect weather conditions: at 1000 feet: 38.7 Miles (62km) … at 30,000 feet: 211.3 miles (340 km) at 39,000 feet: 235 miles (391 km)

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.

How long does it take for a plane to crash from 35 000 feet?

This was the start of the descent that would see the Airbus A330 drop 38,000 feet in just three minutes at a rate of over 10,000 feet a minute and at a speed of 124mph.

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.

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.

How far can you see from a plane at 35000 feet?

The distance here is 170 miles.

What is the highest a plane has ever flown?

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.

What is the air temperature at 35000 feet?

If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.

Can you breathe 30000 feet?

Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you’ll die.

How long does it take a plane to reach 30000 feet?

The average commercial passenger jet aircraft cruises at an altitude between 30,000 and 42,000 feet (ft) (9,000 – 13,000 meters). This means that aeroplanes usually fly between 5 to 7 miles up in the air. It typically takes around 15 to 30 minutes after take-off for the aeroplane to reach this altitude.
