If that is a 747-8 Intercontinental it might be related to the Extended Operations certification program. Or they could just be collecting NAMS data for validating their performance equations.

Didn't know the 748 could do that on a single tank of gas    Probably with no load...wonder how many hours they logged

Looks like they attempted to visit each of the Lower 48 states, though for some reason they steered clear of West Virginia...

Sleep. Read a book. Also a test aircraft will not be packed full of monkeys in cattle class.

I know they've been doing simulated commercial operations lately.

I think it was an 8i. But why did that matter? I thought Boeing was doing ETOPS certifications on both freight and pax versions?

That is correct, but the 747-8F has already completed her ETOPs certification, to my knowledge.

A large portion of the flight took place at FL420 (assuming flight aware data is correct which can be a big assumption to make). That is very unusual...

They flew over every single state except West Virginia and Pennsylvania (unless you count the little piece within the St. Lawrence). Wonder why they didn't get any love from Boeing, especially since Philadelphia has one of their biggest offices!

Why unusual? They almost certainly weren't carrying payload (in order to be able to fly that far) and they're certified up to FL421. If you want minimum fuel burn, go high. The 787 is certified to FL431 and you catch them up at FL430 on flightaware fairly often.

More than walking can be done. That airplane isn't configured with any seats as it is a BBJ (interior fitted after delivery). The engineers and extra crew could be playing football in the cabin of the plane since it is just one huge open area with nothing in it.



If you have never designed an airplane part before, let the real designers do the work!

lame, they didnt spell anything out. A while back the wrote "747" across the US. Also its very common for them to use a high altitude like that so as to stay above most traffic.

It's an operational issue, not a technical limitation--its both possible and safe. FL420 falls above RVSM airspace, where 2000 foot altitude separation again comes into play. For most operations, it is not available. You can do FL410, 430, 450, etc... but 420 is not a "valid" altitude most of the time.

Thus, the 787 at FL430 is much less unusual than the 748 at FL420. The burn is better higher of course, so they might have gotten approval for this specific flight. An ATCer might be able to shed more light on how often this happens and how flexible ATC is at issuing FL420 (or 440 or 460 for that matter...).

I asked today. It was definitely an ETOPS certification flight. So was the Barbados flight.

This particular plane only had something like 12 seats behind the cockpit door for flight test crew. There wasn't even simulated ballast for passengers. Just a boring 18 hours for the folks doing their job.

So, the 748 isn't certified up to FL452 like the rest of the 747 family? That's news to me

Up that high there is relatively little traffic, US ATC is usually pretty amenable to odd requests from experimental/test registered aircraft, and you can get a *lot* more flexibly when you don't care about your route or getting weird temporary vectors and offsets.

I would say less than 1% of the time I can't get the altitude (or altitude block) I want provided I'm willing to wait a few minutes, take a weird vector, or just call ARTCC the day before.

Well, I'm looking at the AFM...don't know what else to say.

All 747 series up to the 744 are certified up to FL 451, only the 747-8 series is (-8F) or will be (-8I) certified to a ceiling of FL 421, probably limited by the new wing profile.

The only exception is the 747-400 Large Cargo Freighter (LCF), only certified up to FL431.
