The 3,mile journey took just more than seven hours, delivering the passengers and crew safely to JFK — albeit a few minutes late. The flight was an important moment in aircraft development, continuing the shift from fuel-thirsty four-engine aircraft toward much more efficient two-engine aircraft.

Four-engine aircraft are fuel hungry. The is an iconic aircraft and is still flying in the fleets of a few airlines around the world. The A is a passenger favorite, but not so much with airlines. Whilst an AvGeek favorite, the is loud and dirty. A throwback to its 60s heritage. The A had been somewhat of an early success, but when Emirates recently decided to cancel its outstanding orders, Airbus announced that it would cease production jet planes with 4 engines not working the aircraft after Jet Planes Scale Not Working the remaining commitments were delivered.

In recent years, the shift has been toward far more fuel efficient aircraft such as the Dreamliner, which I fly, and the A These aircraft can fly exactly the same routes as safely as their four-engine counterparts, but for a fraction of the fuel. Jet planes with 4 engines not working win for both accountants and environmentalists. With the advances in engine and aircraft reliability since the first trans-Atlantic crossing years ago, regulators have allowed two-engine aircraft to fly farther and farther from the nearest adequate airfield in the event of an engine shut down.

Initially limited to just minute single-engine flying time from the nearest usable airfield, the routes that aircraft could fly were pretty limited. Nowadays, minutes is the norm, allowing aircraft to cross the globe on almost any route they wish. The diagram below shows the route from London to New York which an aircraft would have to take under a minute rule and also the route ETOPS allows.

Passengers arrive at their destination sooner and the aircraft spends less time in the air. The environment also benefits with a reduced fuel burn producing fewer carbon emissions. ETOPS is also of benefit in other ways. A good example of this is the Singapore to New York route.

Singapore Airlines used to operate this on an A, but the costs of running the four-engine aircraft made the route commercially unviable. However, with its recent delivery of jet planes with 4 engines not working A, the airline will soon be starting the route again. However, like with any progression, there have to be steps taken to ensure the safety of the operation. Before, during and after each flight, we must adhere to a number of procedures to ensure that everyone on board is kept safe.

The majority of procedures for an ETOPS flight actually take place on the ground before the jet planes with 4 engines not working departs. As mentioned before, the aircraft must stay within its designated ETOPS single-engine flying time from an adequate airfield.

But jet planes with 4 engines not working exactly does adequate mean? An airfield is considered adequate if, at the expected time of use, it is open and available and also equipped with extra services such as Air Traffic Control, emergency services, weather-reporting facilities, lighting and communications.

A runway must be available that provides enough jet planes with 4 engines not working distance, taking into consideration the weight at which the aircraft would be at that stage of flight, the wind, temperature and surface conditions. For more on what factors affect the safe stopping of an aircraft, check out my previous article, The art behind a comfortable landing: How pilots calculate bringing an aircraft to the ground.

The airfield must also have the services and facilities to allow the aircraft to make an instrument approach to the expected runway whilst complying with the minimum weather legalities of the airfield. The weather also has to be good enough. Now, we all know that the weather can be an unpredictable beast at the best of times. So how can we plan seven hours ahead into a flight and know that the weather will be suitable to make an approach?

In order to account for any changes to the forecast, the weather forecast at the earliest time of landing and ending one hour after the latest nominated time of use must be taken into consideration. A PA is an approach flown using the instruments in the flight deck, fed by signals which give both vertical and lateral guidance down toward the runway.

In most large airports, this is done by a setup of antennas on the ground that send signals to the aircraft called an Instrument Landing System, jet planes with 4 engines not working ILS.

An NPA is also an instrument approach but only uses lateral guidance, not vertical guidance. Traditionally these would be based on a beacon on the ground that would emanate a signal to the aircraft to determine its position, but would not provide any guidance for the descent to the airfield.

Firstly, there is a minimum visibility VIS. This is a distance, reported from the airfield, that must be achieved before the approach can continue beyond a certain point. This is the altitude below which the pilots are not allowed to fly without making visual contact with the runway.

These minima are displayed on the approach charts which pilots study before each landing. On any commercial flight, there are strict rules governing how much Jet Engines For Rc Planes fuel we must take. To learn all about that, check out my previous article, How do pilots know how much fuel to take on a flight?

Aircraft engines operate most efficiently at higher altitudes. This is why we fly as high as our weight will enable us. Jet planes with 4 engines not working, if we were having a bad day and there was a loss of cabin pressure, we would have to descend the aircraft down to 10, feet or the lowest possible altitude depending on terrain below us.

Over the Atlantic, this would be 10, feet where the engines would be far more thirsty than at 38, feet.

If we were having a really bad day, we may also lose an engine whilst flying along at 10, feet. In this situation, flying at a much lower altitude on one engine, we must still have enough fuel to reach our nominated ETOPS alternate. Among other things, three electrical generators must be working the normally has six and the engines must have enough jet planes with 4 engines not working to allow the aircraft to reach its destination or divert at the most isolated part of its journey.

During the flight, fuel management is key. To do this, each time we pass a waypoint on the route, we perform a fuel check. We note how much fuel we actually have in the tanks and compare this to the expected amount at this stage of flight.

If, for some reason, we notice that we have less fuel than expected, a plan must be made to deduce the cause. In extreme cases, this may result in a precautionary diversion to an airfield along the route. Flying on a twin-engine aircraft is just as safe as flying on a four-engine one.

Before heading off over remote areas some serious thought is put into the plan based on international aviation laws. Disclaimer: The responses below are not provided or commissioned by the bank advertiser.
