Can a 747 maintain altitude on one engine?

B747 was gliding down, but one engine eventually coughed back into life and here is the answer to our question – it was not enough to maintain altitude. This essentially proved that one engine is not quite enough for the big 747. Boeing 747 has some tricks up its sleeve. It can dump fuel to reduce its weight.

Can a 747 fly on three engines?

Air traffic control expected the plane to return to the airport and deleted its flight plan. However, after consulting with the airline dispatcher, the pilots decided to set off on their flight plan “and get as far as we can” rather than dump 70 tonnes of fuel and land. The 747 is certified to fly on three engines.

What is the replacement for the c17?

The Globemaster III
“It’s really pretty far out there to think about the full replacement of the C-17.” The Globemaster III will be a stalwart for years to come.

Can a 747 fly with just 2 engines?

A 747 can fly on just 2 engines. A 757 can fly on 1. 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.

What can cause multiple engine failures on a Boeing 747?

The most credible causes of multiple engine failures on a Boeing 747 would be (1) bad fuel (which is why testing is so frequent and rigorous); (2) multiple simultaneous strikes by large birds on multiple engines; or (3) volcanic ash ingestion similar to that experienced by the BA 747.

How much thrust does a Boeing 747 have with one engine?

It had 153,000 pounds of thrust remaining with one engine out, versus 127,900 remaining for our re-engined 747 twin-jet. Since the 747–400 has an Operating Empty Weight (OEW) of 412,000 pounds, the twin version would have limited fuel and cargo capacity.

How much would a twin-engined 747 take off?

That would decrease the twin-engined 747’s maximum takeoff weight to 627,000 pounds. This number is in line with the maximum 735,000 pound takeoff weight of the original 747–100, which had 4 x 51,000 pound thrust engines. It had 153,000 pounds of thrust remaining with one engine out, versus 127,900 remaining for our re-engined 747 twin-jet.
