How much HP does a 747 plane have?

How much HP does a 747 plane have?

Approximately 120,000 horsepower on take-off, approximately 60,000 horsepower while cruising, total from four engines. 747 wins a “tug of war” match against Arleigh Burke-class destroyer, which has “only” about 100,000 total horsepower from three engines. It takes two 747s to win against Nimitz-class aircraft carrier.

How far can 747 Glide?

For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi) from a cruising altitude of 10,000 metres (33,000 ft).

Can you barrel roll a 747?

A very comfortable maneuver and easily doable in almost any airplane, including a 747. A barrel roll requires significant g-loading. It is a roll around a point considerably off the longitudinal and pitch axis of the airplane. Typically, it’s a 3–4 g maneuver.

What is the difference between a Boeing 747-100 and 747-200?

After the initial 747-100, Boeing developed the -100B, a higher maximum takeoff weight (MTOW) variant, and the -100SR (Short Range), with higher passenger capacity. Increased maximum takeoff weight allows aircraft to carry more fuel and have longer range. The -200 model followed in 1971, featuring more powerful engines and a higher MTOW.

Is it possible to land a Boeing 747 in an emergency?

The B747 would be severely limited on altitude and it would definitely be an emergency, particularly if both engines out were on the same side. It requires the pilots to wait on gear extension until landing is assured and you are on the final descent part of the approach.

Can a Boeing 747 fly with just 2 engines?

Yes, the B747 can fly on just 2 engines. Not nearly as well as a B777, but better than a 777 could fly if it lost 2 engines! The B747 would be severely limited on altitude and it would definitely be an emergency, particularly if both engines out were on the same side.

When did the first Boeing 747 come into service?

It entered service with Pan Am on January 22, 1970. The 747 was the first airplane dubbed a “Jumbo Jet”, the first wide-body airliner. The 747 is a quadjet, initially powered by JT9D turbofan engines, then GE CF6 and Rolls-Royce RB211 engines for the original variants.
