# Quick Answer: How far from airport do planes start to descend?

Contents

A modern airliner such as a Boeing 777 will start descending from its cruising altitude (for example, 37,000ft) and slowing from its cruising speed (for example, 470kt true airspeed) when it is around 100 miles from the airport.

## How far out do planes start descending?

A: Normally an airliner will begin its descent around 100 to 120 miles from the destination (assuming the cruising altitude is above 30,000 feet). The point of initial descent varies depending on the cruise altitude, the amount of traffic going to your destination and weather conditions.

## How do pilots know when to descend?

Answer: Pilots plan the descent based on the wind and air traffic flow. … In addition to the radar guidance from air traffic control, pilots program navigation computers and radios to ensure proper lateral and vertical paths.

## 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.

## How far do planes drop in turbulence?

The aircraft may be deviating in altitude by 10 or 20 feet. No action is required by the pilot to control the aircraft, but the flight crew may decide to try a different altitude if the turbulence persists. Severe turbulence is extremely rare.

## What is the most dangerous part about flying?

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.

## Are pilots scared of turbulence?

In short, pilots are not worried about turbulence – avoiding it is for convenience and comfort rather than safety. In the best circumstances, pilots can forecast where turbulence is and steer clear of it. “We use met data and forecasts for jet streams to avoid potential areas,” the pilot said.

## How cold is it at 35000 feet?

How cold is it up there? The higher you get, the colder it gets, up until 40,000 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.

## Why do planes speed up before landing?

As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep “flying”. Power from the engines will translate into speed, if not height.

## What does descend at pilot’s discretion mean?

The term “AT PILOT’S DISCRETION” included in the altitude information of an ATC clearance means that ATC has offered the pilot the option to start climb or descent when the pilot wishes, is authorized to conduct the climb or descent at any rate, and to temporarily level off at any intermediate altitude as desired.

## Do planes fly over 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.”

## Is it safe to fly over the ocean?

Can a plane land on water in case of an emergency? Yes it can, but it is not designed to do so, and an emergency landing is always better on land at an airport. … However, as long as sea conditions are smooth and the ditching is performed in a proper way, an aircraft can land on the sea and remain afloat.

## Is becoming a pilot worth the cost?

Here’s the answer – if you still can’t wait to get out of bed, get to the aircraft and jump in the plane by the time you’ve finished your PPL, flying is probably something you’re intensely passionate about – all of the hard work and expense will be worth it for you once you get to co-pilot and see the fruits of your …

## Can turbulence flip a plane?

Except that, in all but the rarest circumstances, it’s not. For all intents and purposes, a plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket. Conditions might be annoying and uncomfortable, but the plane is not going to crash.
