How far can a 767-300 fly on one engine?

Question

Just sitting around SFO waiting for this plane to get its engine fixed...was just kind of curious to see what my chances of landing safely were. :P

Answer 1

A 767-300 ER can fly 240 minutes on one engine. That is about 3/4 across the US.

The FAA had a long-time rule dating back to propeller aircraft with 2 piston engines, requiring them to fly within 60 minutes of a diversion airport, whether over land or water, in case one engine failed. Over the years, turbine engines (both jet and fans) have demonstrated significantly higher reliability performance due to engine design and maintenance.

The FAA modified its ETOPS (Extended Twin-engine Operations) rules in response to Boeing and Airbus arguing that a 60-minute overwater operations for 2-engined aircraft operating on one engine restriction was too conservative.

ETOPS range was initially increased from 60 minutes to 90 minutes (the European Aviation administration permitted Airbus to use a 90 minute rule), and then it increased ETOPS to 120 minutes.

A Boeing 767-300ER was the first twin-jet to be certified as ETOPS-180, operated by TWA between St Louis and Frankfurt (Germany.)

The B-777 has been allowed to operate with a 15% increase, to ETOPS-217.

In actuality, there is a 100% safety factor in the ETOPS minute rating. During ETOPS certification, the aircraft manufacturer must demonstrate that, during the diversion test flight, the flight crew is not unduly burdened by extra workload due to the lost engine and that the probability of the remaining engine failing is extremely remote. For example, if an aircraft is rated for ETOPS-180, it means that it should be able to fly with full load and just one engine for 3 hours..

Answer 2

No multiengine aircraft is certified to take-off with only one engine .Can it do it? Possibly, with enough runway (maybe 5-10 MILES) , minimum fuel , no load (pax or frieght).

All the etops answers are mostly correct.These limitations allow extended flights , until a suitable landing airport can be reached or return to the originating airport

Engine power is thrust, be it jet,fan jet ,propellor. Its purpose is to get to a speed quickly enough so the aerodynamics of the wing lift the aircraft into flight and maintain that speed and above so it keeps flying.
The original jets had more engines because they were not as powerful.The newer generation are more efficient and more powerful. The 757-200 fuselage is a basic Boeing narrow body,a longer 727-200 design. The engines on a 727 (3) only produced approx 15,000 lbs.of thrust each. Thats 45,000 lbs. of thrust to move 200,000 lbs. of aircraft. The 757 has 2 engines EACH producing 45,000 lbs.
The engines on the 767 are generally in the 80,000 lb.thrust rating , with the 777 in the 90-100,000 lb.thrust rating. (there is a formula to convert thrust to horsepower,but the generally accepted rate is 1 lb.= 1 hp at altitude)
Hope you have a safe trip.

Answer 3

Modern airliners CAN take-off and climb with one engine (although it is for emergencies only). So, cruise flight and landing on one engine is a non-event as far as the aircraft goes.

On the takeoff roll, as the aircraft accelerates, the co-pilot calls out "V1" to the flying pilot, advising that the aircraft has reached the speed (V1) that takeoff WILL BE CONTINUED even if an engine fails. At this speed, the flying pilot removes his/her hands from the throttles, because the takeoff will continue regardless of whether an engine fails or not.

Answer 4

ETOPS (Extended-range Twin-engine Operations) is an acronym for an International Civil Aviation Organization (ICAO) rule permitting twin-engined commercial air transports to fly routes that, at some points, are farther than a distance of 60 minutes flying time from an emergency or diversion airport. This definition allows twin-engined airliners—such as the Airbus A300, A310, A320, and A330 families, and the Boeing 737, 757, 767, and 777 —to fly long distance routes (especially over water, desert or remote polar areas) that were previously off-limits to twin-engined aircraft. ETOPS is sometimes read (humorously) as Engines Turn or Passengers Swim.

Answer 5

Assuming engine loss while at cruise, the airplane can continue on until it runs out of fuel. In point of fact, even though no pilot would do it if he had other options, as long as the aircraft loses the engine immediately after take-off, it can climb to a lower than normal altitude and continue flight until it runs out of fuel. I should point out that this is true for jets, not piston engines. Lose a piston engine at take-off and it gets interesting. Normally controllable, but very interesting.

Answer 6

It can fly easily and can also land safely bcoz in all commercial planes, only one engine can create enough amout of thrust to fly and land. But the takeoff definately make a crash in under 2 minutes of take off.

Answer 7

Actually there have been several cases where both engines have failed on twin jet powered commercial aircraft. But all twins flying over water routes are designed by the company and ceritifed by the FAA for those single engine operations.

Answer 8

the answer regarding ETOPS is right on the money, you don't have anything to worry about. fyi, there has NEVER been a case where a twinjet has suffered failure of both engines on the same flight of unrelated causes. the odds of this are so small, that's why the FAA allows 767's, A330's, etc. to operate routes such as Los Angeles-Tokyo, Vancouver-Shanghai, where virtually all of the flight is spent over water with no landing sites nearby.

Answer 9

all you need is a strong rudder
Edit: a Boeing 777-300 flew for more than 5 hours on one engine
(i know its not a 767 but it gives you an idea)

Answer 10

depends on what the fuel load is, where the center of gravity is, weight of the aircraft, lots of factors play into how far it could fly, but depending on conditions, pretty far. im an aircraft mechanic on the B-52H, it can fly w one and take off with 2, even though it has 8 motors. hope this helps
