# Your question: At what speed does an aircraft take off?

Contents

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.

## At what speed does a Boeing 747 take off?

A fully loaded Boeing 747 ‘Jumbo Jet’ on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph.

## What is the takeoff speed of a 737?

Aircraft Takeoff Weight Takeoff Speed
Boeing 737 100,000 lb 45,360 kg 150 mph 250 km/h 130 kts
Boeing 757 240,000 lb 108,860 kg 160 mph 260 km/h 140 kts
Airbus A320 155,000 lb 70,305 kg 170 mph 275 km/h 150 kts
Airbus A340 571,000 lb 259,000 kg 180 mph 290 km/h 155 kts

## What is take off safety speed?

This speed is nicknamed a “take-off safety speed”; it is the speed an aircraft with one engine inoperative must be able to attain in order to leave the runway and get 35 feet off the ground at the end of the runway, maintaining a 200 ft/min climb thereafter.

## 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.

## How fast is a 747 in mph?

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

## 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 planes use full throttle on takeoff?

Answer: Most takeoffs use “derated” thrust to save engine wear. For each takeoff, performance is calculated, the necessary power setting is determined and the thrust setting is made. … When using this method during takeoff, it is always possible to increase to full power if the situation requires.

## Why do planes turn after takeoff?

Originally Answered: Why do airplanes turn immediately after takeoff, and why not after reaching the stable height? This is done to avoid the wake turbulence caused by its engine of the aircraft that just took off, so that next aircraft can takeoff without any delay.

## What happens to V1 on a wet runway?

When a wet runway is considered a VEF (about 10kts lower than before) is used with a correspondingly lower V1, called V1 WET. The idea of reducing the V1 is to improve the chances of stopping. However if the decision is to “GO”, then reducing the V1 increase the TOD (i.e. accelerating with a failed engine).

## What is rotate when taking off?

In aviation, rotation refers to the action of applying back pressure to a control device, such as a yoke, side-stick or centre stick, to lift the nose wheel off the ground during takeoff. … A certification test is required to show that a new aircraft design will still take off safely with the tail dragging on the runway.

## What does V1 mean when taking off?

A: V1 is the speed by which time the decision to continue flight if an engine fails has been made. It can be said that V1 is the “commit to fly” speed. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed.

## Do pilots get scared?

It is possible that a pilot may be nervous, but they will act in accordance with their training. My experience is that professional pilots are people who deal with abnormal or emergency situations effectively.

## What do pilots say when landing?

Thank you.” To indicate the landing clearance or final approach, the Captain will either make the following announcement and/or blink the No Smoking sign. “Flight attendants, prepare for landing please.” “Cabin crew, please take your seats for landing.”

## Do planes always dump fuel before landing?

Usually, airplanes won’t dump fuel in mid-air or when taking off or landing; they only do so immediately before they land the plane.
