Unmatched Fuel Efficiency And Exceptional Environmental Performance of 787-8 Dreamliner

Unmatched Fuel Efficiency And Exceptional Environmental Performance of 787-8 DreamlinerResponding to the overwhelming preference of airlines around the world, Boeing Commercial Airplanes’ launched the 787 Dreamliner, a super-efficient airplane. An international team of top aerospace companies is building the airplane, led by Boeing at its Everett, Wash. facility near Seattle.

Unparalleled Performance

The 787-8 Dreamliner will carry 210 – 250 passengers on routes of 7,650 to 8,200 nautical miles (14,200 to 15,200 kilometers), while the 787-9 Dreamliner will carry 250 – 290 passengers on routes of 8,000 to 8,500 nautical miles (14,800 to 15,750 kilometers).
In addition to bringing big-jet ranges to mid-size airplanes, the 787 provides airlines with unmatched fuel efficiency, resulting in exceptional environmental performance. The airplane uses 20 percent less fuel than today’s similarly sized airplanes. It will also travel at a similar speed as today’s fastest wide bodies, Mach 0.85. Airlines will enjoy more cargo revenue capacity.
Passengers will also see improvements on the 787 Dreamliner, from an interior environment with higher humidity to increased comfort and convenience.

Advanced Technology

The key to the exceptional performance of the 787 Dreamliner is a suite of new technologies developed and applied on the airplane.
Composite materials make up 50 percent of the primary structure of the 787 including the fuselage and wing.
Modern systems architecture is at the heart of the 787’s design. It is simpler than today’s airplanes and offers increased functionality and efficiency. For example, the team has incorporated airplane health-monitoring systems that allow the airplane to self-monitor and report systems maintenance requirements to ground-based computer systems.
New engines from General Electric and Rolls-Royce are used on the 787. Advances in engine technology are the biggest contributor to overall fuel efficiency improvements. The new engines represent nearly a two-generation jump in technology for the middle of the market.

The design and build process of the 787 has added further efficiency improvements. New technologies and processes have been developed to help Boeing and its supplier partners achieve the efficiency gains. For example, manufacturing a one-piece fuselage section has eliminated 1,500 aluminum sheets and 40,000 – 50,000 fasteners (source, more info)

Flying the Boeing 787 Dreamliner Sim

For all of our student pilots enrolled in flight training programs, below we outline the experience of flying Boeing 787 Dreamliner, written by By Les Abend and published in Flying Magazine. Read full story

I slid into the left seat and surveyed the entire cockpit. Except for the HD-quality flat screens and the virtual FMC (flight management computer ), the basic configuration was the same as the 777’s. I studied the instrument panel in an attempt not so much to acquaint myself with the array of information available but to figure out how to operate all the stuff.

As opposed to the 777, the screens are larger, giving them the capability of being split. In addition to standard map and PFD information, the screens can display checklists and system synoptics. The FMCs are simply virtual picture displays of the old models. Because they are virtual, most of their direct tactile key functions are absent. The same mouse pad found on the 777 directs a cursor for function selection on the FMC. A twist-knob and push-button combination similar to a Garmin GNS 530 can also move the cursor. What’s also really cool is the ability to “float” the cursor from the instrument panel screens down to the lower screens of the center console.

Another really neat feature is the flight profile on the lower portion of the pilot’s map screen. The profile adds an additional level of terrain situational awareness. The half-compass rose underneath the main PFD is more of a mini map and now has the ability to display either terrain or weather. On the 777, either can be displayed, but not both at the same time on the same pilot side.

Nothing new for my fellow GA pilots, but the 787 can display the airport diagram with a moving map. As a matter of fact, the detail allows me the ability to locate my arrival gate.

Another standard issue on the 787 is the HUD on both sides of the cockpit. For me, this was a new device. I struggled with the information, dividing my attention between the HUD and the instrument panel PFD. When it was diplomatically suggested that I keep the vector circles aligned, HUD flying became a whole lot easier.
My quick taxi to Boeing Field’s Runway 13R gave me the opportunity to sample both the moving map and the simulator’s virtual reality. The virtual reality was detailed enough to include perimeter road traffic. That being said, I was told that the boats from nearby Lake Union created wakes but no movement. I hope the programmers don’t lie awake at night attempting to find a solution for that discrepancy.

My coach, Randy Neville, the 787 chief test pilot, and Ted Grady, a 787 instructor, joined us before departure. With the visibility set at 300 feet RVR, I used the HUD for takeoff. I kept the blue side up without breaking anything. I felt almost immediately comfortable.

We selected an FMC course to Moses Lake, a joint-use military airport in the Washington state desert area. The airport was a typical Boeing test flight destination.

I sampled an ILS approach first. Randy helped with the electronic checklists while I moved the flaps and the gear. A great feature of the checklist is that an EICAS message will be displayed if an item is not completed.

Without knowing speeds or power settings, I accomplished the arrival with a limited amount of issues. As a matter of fact, my touchdowns for the session received accolades. Apparently this particular simulator had a reputation for “stiff legs.” Beginner’s luck?

A glutton for punishment, I requested an engine failure for the next takeoff. Out of courtesy, Ted asked me if I wanted to know which engine would be unfortunate.
“Surprise me,” I responded.

If I had allowed the airplane to perform by itself through the very responsive TAC (Thrust Asymmetry Compensator), the engine failure would have gone almost unnoticed. Instead, I assisted and then succeeded in making the process more difficult. The 777 has a TAC and associated switch on the overhead panel. The 787 has no switch; the system is always available.

We conducted a VNAV approach, which was as simple as selecting it from the database . No more gyrations of recalling procedures and setting altitudes on the mode control panel. Just press the “approach” button. The end.
Our return to Boeing Field involved a relatively new procedure called a GLS approach. A ground-based station uses GPS signals to compute precise data to create a virtual ILS for not just one airport but for many airports in the surrounding area. No signal interference from an airplane or vehicle can occur, and the accuracy exceeds that of a traditional ILS. Execution of the approach was transparent to normal procedures.

Almost transparent was the actual flying of the 787. If the FAA-approved, five-day 777/787 differences training is adopted by the airlines, I don’t expect major issues.

My only complaint? I wished I hadn’t waited so long to experience Airline Pilot Disney World.
