# How fast do planes fly in KM?

Contents

The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph).

## How high can planes fly in KM?

It would be reasonable to wager that the majority of air passengers have never questioned why the traditional flight altitude is 35,000 feet (10,600 metres). The number has entered aviation lexicon as the catch-all height at which most aircraft travel from A to B.

## How far does a plane fly in 1 hour?

As a general rule, airplanes can fly from 550 to 580 miles per hour, although this is most common with commercial planes. However, this is only an average because wind and the elements can affect that number.

## How fast do planes fly?

How fast do commercial passenger jets fly? A typical commercial passenger jet cruises at a speed of about 400 – 500 knots which is around 460 – 575 mph. Generally speaking, the higher the aircraft flies, the faster it can travel. It cruises at this speed at a height of about 36,000ft.

## Do planes fly at maximum speed?

Nope, planes are not flying at the maximum speed . Airlines saves fuel flying at optimal cruise speed. On Flightradar24, I saw a Boeing 777 flying at 780 mph.

## Why planes do not fly over Tibet?

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.” … The Himalayan region has almost no flat surfaces.

## 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 slowest speed an airplane can fly?

Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).

## What is the fastest jet in the world?

The 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. Key elements of the SR-71’s design made this possible.

## How many miles does an airplane last?

A 30-year lifetime. 3,500 hours a year as an average. An average speed of 500 miles per hour. 30 x 3500 x 500 = 52,500,000 miles.

## What is the most dangerous part of a flight?

Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.

## Do pilots sleep on long flights?

Do pilots sleep in flight? The simple answer is yes, pilots do and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.

## Do planes fly faster over water?

At the cruising altitude of most airliners, there is no noticeable aerodynamic difference between being over land or over sea. … In the middle of the ocean the quickest route may take the aircraft outside of this range, so it will have to fly closer to land, or even in certain remote parts of the world, still over land.

## How fast can a 747 fly?

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