## How many engines can fail on a 747?

While it’s very clear that a 747 is unable to properly fly with the failure of three engines, we can see that a single functioning engine would at least extend the aircraft’s distance and prolong its time in the air. Hopefully, this would buy enough time and distance for the 747 to reach a suitable landing spot.

## Can a 747 take off with 2 engines?

A 747 cannot takeoff with just two engines because the time it would take to pick up enough speed would have it half way there, but once its in the air, they’ll keep it moving. 2.

## Can a Boeing 777 fly on one engine?

## What speed do planes land at?

At cruising altitude, most commercial airplanes fly at a speed of roughly 500 to 600 mph. When landing, however, they must reduce their speed. A typical 747, for instance, has a landing speed of about 160 to 170 mph.

## Why do planes turn after takeoff?

During takeoff, air accelerated behind the prop (known as the slipstream) follows a corkscrew pattern. As it wraps itself around the fuselage of your plane, it hits the left side of your aircraft’s tail, creating a yawing motion, and making the aircraft yaw left.
