Cool article and video on brake tests in 747-8F

Now if they'll just go ahead and spend less time making youtube videos, certify it and give us a few copies that we have on order, my upgrade time would thank them.

Watching that video, looks like the test airport is VCV. Any solid info?

You are correct. I was about 3 miles from the airport at the time and heard the testing. Later verified by personal chat with GE engineer on site.

In other news, today I watched a V1 rocket motor mounted on a trailer perform two test ignitions. 1,000*F made the entire casing glow cherry red. If that wasn't enough, I watched an Allison V16 mounted on trailer fire up. Ran up to 2,600 RPMs. The right stack ran hot due to fouled plugs. Watched Clay Lacy barrel roll the LR24. Why would anyone install a smoke system on a Lear is beyond me. Chino baby!
 
Ok so my question is how many times does a certain test (aborted t.o.) have to be performed before is considered something that can be published?

I like the 748's auto-popping tires though, is that something new or do other airliners have those?

Every jet I've flown has had the same set up. What they do is put "fuse plugs" in the wheels that melt at a lower temperature than the wheel. IIRC, the big idea to to keep the tires from exploding. The fuse plugs melt and let the air out prior to that occurring after heavy (and even sometimes normal if there is something wrong with a tire or brake) braking.

Safety tip: Brakes are hottest about 10 minutes after their heaviest usage, so approach tires of inbound aircraft from the front or back in case the fuse plug lets go.
