Final gauntlet completed

Just before the start of the long holiday weekend here in the U.S., the 787 team completed the ‘round-the-clock final gauntlet testing on ZA001.

On the evening of July 2, we wrapped up 18 hours of simulated flying on our first flight test airplane.


ZA001 during final gauntlet testing last week in Everett.

This final gauntlet round included a number of scenarios ranging from normal flight to systems failures – a process that puts the airplane through its paces and gets the airplane ready for flight.

Not only that, though, this process puts the Flight Test and Operations team through its paces too. “Flying” all day and night requires a lot of organization, as you can imagine. There are a number of shift changes and the handoffs have to be seamless.

In gauntlet, our flight test engineers, at work stations inside the airplane, monitor the 787’s behavior. The data is recorded and reviewed after the testing.

We’re still going through the data, but we did discover a few things during final gauntlet, most of which we resolved during the testing.

As we’ve said before, this is all part of the process, and why we do testing in the first place.

Norman (Long Beach, California, United States):

This is good news, the airplane and it's technical systems and avionics are new so not everything is going to be perfect but so long as their are no major malfunction of a system and the small problems can be resolved quickly in the gauntlet, the progress of the testing should remain on track.

Richard (Lake Tapps, WA):

So now what's next? Is the cause of the first flight delay getting resolved? If the final gauntlet testing is done, does that mean ZA001 is ready for first flight, minus the fix needed?

TC (Mt. Vernon, WA):

"Flying" all day and night probably requires a lot of donuts, which could explain the bread truck parked by the plane.


We are pleased to read that systems seem to be in order but other things interfered with first flight and we are all anxiously awaiting to hear what will be done to correct the problem and move the plane into the air. Scott Francher said that the temporary fix could be done "with a few pieces held in his hand an "in situ""

It would be very helpful if you could tell us something about the process in front of the 787 and how long it will be before we should expect flight. Several of the Financial analysts are calling for everything from three to a six month wait. They see to have drawn some conclusions based on their early conversations.

Perhaps you could bring us all up to date
