Four 777Xs On the Ramp

The 777X initial airframe has already made it on the blog when it was parked on the ramp and when it undertook some taxi trials.  It has since had the dodgy engines removed and I assume some more trustworthy examples are on their way.  First flight will not be this year, though, based on what I am reading in the press.  While the start of flying has not been achieved, production has continued.  The initial customer aircraft have also now shown up.  I understand that Lufthansa will be receiving at least one of these jets.  The flight line now has four jets parked up – two in house colors and two all white.  Hope we will see them up and active before too long!  I hear a fifth came out with Emirates’ wing tips just after I took this!  I have another primer one since which is below.

An MRJ Comes This Side of the Cascades

A lunchtime jaunt up to Everett was the result of ATS carrying out a test flight of a Janet 737.  I got to the field with a little time in hand and was looking on FlightRadar24 for the position of the inbound jet when I saw something orbiting north of me up near Concrete.  It turned out to be one of the Mitsubishi MRJ90 test aircraft.  It was flying a series of patterns up there.  Since they carry out the test flying from Moses Lake, I wasn’t so surprised.  More importantly, I figured that they would head back to base when they were done.

Imagine my surprise when the radio burst to life with their callsign setting up on the approach.  A Janet was worth the trip but the MRJ was truly a bonus.  I have only seen one before and that was a delivery flight from Japan to Moses Lake that staged through San Jose and was in the blog here.  I hoped it was a different jet, but wasn’t going to gripe if it wasn’t (and I was pretty sure it wasn’t based on recollection of the registration).

The jet hummed its way down the approach and landed in front of me (and a few others that either knew or had got similarly lucky).  It them taxied back and held in front of FHCAM.  There was a departing Embraer in front of it so I figured it was waiting for them.  However, they departed and it didn’t move for a while.  I needed to head back so was desperately hoping it would go soon.  Just as I was about to give up, they released the brakes and taxied to the hold.  The departure was pretty quiet with the Pratt GTFs not making much noise at all.

The original colors of the jet appear to have been overtaken by test markings.  There were some details around the engine inlets and the upper rear fuselage had been painted black.  I suspected this might be for testing of water ingestion to help visualize the water flow but if anyone knows better what the purpose is, please do let me know.

Fatigue 777X in the Test Frame

Having seen the fatigue test 777X emerged from the production hangars (as I covered in this post), I assumed it had moved to the test area. I once made a drive around the back of the factory at Everett to see some of the discarded airframe structures that they have stored once they are finished with.  I wrote about that in this post.  The fatigue test area is in the same place so I thought a drive around was a good idea.  Sure enough, the 777X was in the fatigue test rig.  I guess it will be there for quite a while as they push and pull it to simulate many cycles of loading and see whether the structure has any long term issues to be addressed.

Fatigue Test 777X Emerges

The first two flight test 777X airframes have been on the flight line.  However, something different was sitting outside the production hangars at Everett.  It was a 777X but it was missing a few more cosmetic parts.  This was the fatigue test aircraft.  It was being readied for movement around to the area of the plant where they undertake the fatigue testing.  This will probably be the last time you get to see it like this.  Once testing is done, I suspect it will rapidly end up in pieces for further analysis.

Gulf Air 787-9

I caught this Gulf Air 787-9 as it returned from a test flight to Paine Field.  It was at the end of the SkyFair event so the crew will have noticed that there were a lot of people on hand to witness their landing.  Not a particular problem of course but probably one of the few landings of the Boeing production tests to get a large crowd.

West Seattle Bonuses

We made a trip to West Seattle with our guests while they were here.  We were looking at the view of the city and also wondering what wildlife might show itself.  I got a benefit in that departures from SeaTac and Boeing Field were coming to the north.  I got a couple of nice airliner shots as they climbed out over us.  They weren’t the only ones though.  A KC-46 launched out of Boeing Field and climbed over us as it went off to its test area.  I wasn’t paying attention, but my guests spotted something rocketing up behind it.  An F/A-18C Hornet from the Strike Test unit was following it, presumably for some test work.  It climbed rapidly but then leveled out, I assume to stay below the departure routes from SeaTac.  Not a bad bonus for me while showing the sights to my guests.

A Further Trial in Focus Stacking

In a previous post I wrote about a focus stacking effort I made with images of a model aircraft at a show.  I had been meaning to have another go at this and do so in a more controlled environment.  I then ended up buying myself a macro lens for use in my negative scanning efforts and immediately started playing with it to shoot things close up – it’s a macro lens for goodness sake!

As an f/2.8 lens, when shooting macro shots, the depth of field is really shallow.  This got me thinking about trying another focus stack.  A small Leatherman seemed as good a target as anything.  I set up with manual focus, put the camera on a tripod, went to manual exposure and then shot a sequence with small changes to the position of focus for each shot.  Then it was off to Photoshop.

Photoshop did a pretty good job really.  The distortion of the areas out of focus means that the area that the subject covers can vary quite dramatically as the focus shifts backwards and forwards.  The algorithm did well getting things masked and blended.  The only bit it struggled with was at the very top where the knurled edge seemed to confuse it a bit.  The top shot is the finished effort while two others are included to show how much things are out of focus in the individual shots.

737 First Flight

I was walking along the trail that goes through the park next to the airport at Renton taking a look at the stored jets.  There is a bridge across the river that is used by Boeing to move jets from the production areas to the flightline and, as I got close to the bridge, I could see the tractor hooking up to a China Southern 737-800 that had yet to be painted.  They looked like they might bring it across the bridge.  I figured I might linger and see what was up.

Sure enough, they started to pull the jet out and towards the bridge.  I stayed out of the way but the wings of a 737 hang over the trail when they are moving it.  This was not a problem so they were happy for me to stand there as the jet was moved out.  I figured a little iPhone video was in order.

They pulled the jet onto a taxiway and left it there so I figured it might be heading out on a test flight.  With the light now slightly to the other side, I chose to go back to the car and move to the overlook on the west side of the field.  The jet was starting up but they clearly had a few things to run through so I had time.

They taxied to the south threshold which initially disappointed me.  The wind had flight operations in the other direction which would have meant a takeoff towards us and into the light.  Going the other way meant they would be airborne a long way away and heading over the lake.  What I hadn’t figured on was, just like at Everett, they would do a run with an abort first prior to flying.  They carried this out and were then at the north end of the field.

A turnaround at the far end of the field and they were soon lined up.  A floatplane was flying about in the background as they got ready to take off.  Then it was power on and rolling.  There was a lot of crap in the foreground and this was a bit of an obstruction at the point of rotation but I was able to get some good shots as they got airborne and climbed out past us.  The green primer/protective film was glinting in the sun.  The flight will have ended at Boeing Field where I hope everything was trouble free.

RAT Noise

UPS is buying a bunch of 747 freighters at the moment.  I have shot a few of them including examples here and here.  The route back to Paine Field takes them across our area when the pattern being flown is a northerly.  I grabbed the camera to see this primer example heading over.  As the plane flew by, there was a lot more noise than would be normal for a jet on the approach and it had a vibrational element which made me think the RAT might be deployed.  Sure enough, when I checked the shots, the RAT could be seen under the wing route.  This is a normal flight test requirement so nothing to be concerned about but this was the first time I had heard a jet at speed with the RAT out and I was surprised how loud it was.

One of the Early F-16s

The early versions of jets are often repurposed throughout their life.  They serve a role for testing but they are not configured like production jets and to make them so is too expensive to be worthwhile.  Besides, they are instrumented to some extent so they can be useful for carrying out alternate tests.  As a result, they often get used for trials, research tasks or development of alternate concepts.  The early F-16s did a lot of this sort of work and ended up in some odd programs like the AFTI effort.  Sitting outside at the Frontiers of Flight museum is one of these test aircraft.  It spent its life with General Dynamics (now Lockheed Martin) at Fort Worth and, once it was done with, it found a new home at the museum.  Compared to the average F-16, this jet will have had a lot of interesting experiences!
