Boeing 777-200LR Completes Taxi Test

Sun Mar 06, 2005 5:17 am

OK, I find it hard to believe this hasn't been posted yet, but I couldn't find it with the search facility. So, here it is. the B772LR has completed taxi tests and the first flight is near:

What does a taxi test involve? The thrust reversers are deployed in the pic.

Well it wasn't just "casually" rolling around, according to the release it was moving around at 80 mph.

Did the taxi pass the test?

Seriously, the thrust reversers will have been used to prevent it falling off the end of the runway after scuttling down at nearly T/O speed

It's casual when it's a plane built to fly 37,000 feet at 550 miles per hour.

Besides, I do 80 on the freeway through downtown.

Does anyone have any A380 taxi pics yet? Seems strange timing. I mean it seems Boeing has this a/c out a lot faster than the A-380. Is that because it's a different version of same type aircraft? (PS. This is not a ploy to start a fight, just a question!)

This is most likely due to the fact that the B772LR is a derivative of a plane which is already flying, whereas the A380 is a totally new airframe. So, obvioously, Airbus has a lot more testing to do before it can allow it to fly.

SNATH is 100% correct. With the A380 being brand new and having growing pains its no big deal it is taking a little longer. The big test fot the 777LR is when it starts using more systems that are new to the 777 family, which I don't know how many there are. Also, the biggest deal really with this plane is when they push the range on test flights. Can't wait!

I know Boeings 777-200LR use the most powerful jet engines .
However , I'm curious if the 777-200LR's engines have a larger diameter than other 777s ?

Still waiting for some orders for the Worldliner ?  confused

No, the GE90-115 and GE90-94 have the same fan diameter. The -115 has a reshaped fan, reinforced/improved core.

The PW4000 has a 112 inch fan, the Trent 800 has a 110 inch fan

This is sort of out of place in this topic but I remember reading on airliners.net somewhere that all the people in the A380 during its test flight will be wearing parachutes. Also, the cargo door will be rigged with explosives in case of an emergency. I was just wondering if this is normal for every test flight or it's just for the A380. It just seems kind of extreme to have explosives on board.

In fact, this is not quite correct, as the GE90-110 is actually a derrated GE90-115, used on the B773ER (110K vs. 115K lb of thurst).

Apologies for being really pedantic!  sorry

No, the thrust reversers were used in order to test the thrust reversers. The aircraft is quite capable of stopping with brakes only, as required by FAA regulations. If you stop to think about it, a rejected takeoff scenario which absolutely required the use of thrust reversers would not be logical, since many of these are engine out scenarios, where you wouldn't have both reversers!

How would they ever possibly hope to evacuate an airplane in such a manner? It's almost impossible to "bail-out" of a commercial airliner

Actually, according to GEAE.com, the 115B has a maximum diameter of 135 inches, whereas the earlier 90s have a max diameter of 134.
The fan diameter has grown from 123 to 128 inches.

So I'm confused ... who were trying to prove wrong? Me or yourself. Because you make this statement as if I said 199ft was the length which we all know you did. At any rate while trying to make another A.net member look stupid, you were the one who ended up with egg all over your face because however miniscule the wrongness of your technicality might have been ... you were still wrong yourself.
