Tailskid On A 777X

There is plenty of the 777X on this blog. The delays for the test programs and the likelihood that service entry will slip in to 2024 means that test aircraft are all that is going to be available for a while yet. Even so, with four test aircraft in use, there is plenty of test activity underway. One of the more dramatic testing processes is the minimum unstick testing.

The test is to determine the maximum lift at takeoff in various configurations. This allows calculation of the required take off speeds and the runway distance required. The test involves accelerating the aircraft more slowly than usual and pulling the noise fully up. The tail is dragged along the runway and the aircraft will then get airborne once it reaches sufficient speed.

The test requires a decent runway length and, presumably, nothing much off the end should anything go awry. To protect the aircraft, a tailskid is fitted to the rear fuselage to allow the crew to drag it along the runway surface without damaging the airframe. The skid frame is a metallic structure but I am not sure what the wearing surface is for the 777X. In the past, wood has been used as the abradable element.

WH001, the first 777-9 airframe, is the one that is going to be used for these tests. It has been fitted with the skid. I’m not sure whether the testing is already underway or whether it is ready for future use. I shot it on departure on a couple of occasions.

Asia Pacific 757

An unusual operator is a good reason for a trip out. I had seen some 757 flights in and out of Seattle that seemed to be running a circular route including LA and Hawaii. The airline was called Asia Pacific Airlines and was flying 757s. However, I didn’t have the opportunity to get to see them while these flights were underway. Jump forward to Christmas Eve and I had a day off and they were coming in to Boeing Field. This seemed like it was worth a trip.

They appeared to be providing additional capacity for UPS which was dealing with the big rush in the last days before Christmas. Although the jet was due in a bit later than ideal, I was definitely hanging around to see it. I had got everything done for Christmas so I wasn’t under pressure. The green and white scheme is an interesting change from the usual UPS colors. It landed and taxied to the UPS ramp where the ground crew went to work unloading and reloading it. I didn’t wait for departure, though. Christmas was coming!

Sunset UPS Departure

The UPS traffic at Boeing Field was busy in the run up to Christmas. As the light was starting to fade and the day end, another UPS jet taxied for departure. It got airborne and headed off to its next destination as the sky in the background had a nice warm look to it.

United Max On Test

With the grounding order rescinded but the FAA, Boeing was getting Max jets ready to go for customers that were in a position to take delivery – namely US airlines and those that use US registered aircraft. United has a bunch of Max 9 jets on order and one of them was making a test flight just before Christmas. I got to see it return from its test. It taxied back in the south entrance to their ramp past a bunch of other test airframes awaiting acceptance.

UPS Getting Very Busy

In the run up to Christmas, online retail had clearly been very busy. UPS runs their Seattle flights to Boeing Field and, while I was there, the traffic levels were well above the norm. I have posted the Asia Pacific 757 freighter in a previous post but UPS’s own fleet were really moving. Arrivals and departures were pretty frequent. As soon as the jets were on the ramp, the team whirled into motion getting the containers off and loading up the outbound loads.

Kenmore Caravan on the Short Runway

Kenmore’s floatplane operations are the best known part of their business but they have a lot of flights using the Cessna Caravan from land bases. One of them returned to their Boeing Field base while I was there. The Caravan is perfectly capable of using the short runway at the airport and, with plenty of traffic using the main runway, this one came in on the short side. That brought it closer to me so I was pretty happy about it.

G650 Heading Out

My first trip to my new spot at Boeing Field, as described in this blog post, resulted in a fair bit of activity. Not long after I got there, I saw a Gulfstream G650 taxiing from the south end of the ramp towards the departure runway. This location gave a few spots where the jet was clear of buildings and you could get a shot. It ended up holding at the threshold for quite a while as other movements came and went.

Once it got clearance, it made a spiritedly takeoff. Long range bizjets are rarely making use of their full capabilities so, when they are lightly loaded, they are off in quick time. This was the case for the G650 and I got some shots of it rotating and climbing away. Not a bad start for this spot.

Asia Pacific 757 Freighter Helping UPS

Looking for something unusual keeps things interesting when you have been shooting the same stuff for a while while not able to go anywhere. I had seen a couple of movements in recent months of Asia Pacific Airlines and their Boeing 757s. However, I had never been in a position to catch one. Christmas Eve I was off work and one was due in to Boeing Field. It was on their own flight number but I had a suspicion that they were supporting UPS.

Sure enough, when the jet landed, it taxied up to a spot on the UPS ramp and started unloading. UPS had been running a large amount of movements through Seattle that day and the preceding days so I guess the Christmas rush meant it was necessary to charter in additional capacity to deal with the demand. An interesting looking plane and nice to see something different for a change.

Boeing Flight Test Ramps

From my new spot, you have a good view of the main civil ramp at Boeing as well as a slightly more distant view of the military ramp. The civil ramp was full of Max jets waiting to get delivered now that customers can start accepting the jets again. Not all agencies have cleared the Max so I guess Boeing was focusing on those that have and aiming to get as much cash as they could in before year end. You could also see the stored jets on part of the ramp as well as those in the parking lot across Marginal Way.

There were three 777X development airframes parked while the second jet was out on a test flight. I was hoping to get it returning but it was out over the Pacific off the Oregon coast and I rightly guessed that, despite the online forecast, it wouldn’t be back before sunset. The military ramp was a little quieter than I expected with a couple of KC-46s and some P-8s including the next one for the Royal Air Force. There were also two KC-46s up on the civilian flight test ramp. Plenty to see and it would have been better in morning light.

Return of a P-8 Test Flight From Above

The first decent sized arrival I got on my BFI visit was a US Navy P-8 Poseidon returning from a test flight. It gave me a chance to get the hang of picking the arriving planes up against the background and working out their positions as the are on final. Things are pretty cluttered in the background which doesn’t help make a photo look interesting but, once they are over the airfield itself, the background is a lot cleaner and the plane stands out more.

Once over the runway, everything is unobstructed so you get a good view of the touchdown and roll out. The runway wasn’t too damp so not much in the way of spray from reverse thrust but a good amount of tire smoke as the mains hit the ground. Heat haze was not too much of a problem as the conditions were not too sunny but you still had to be pretty close in before the shots were sharp enough to look at closely.
