Re: KRnet> Brake performance & taxi testing

A few words on brake performance and taxi testing.   Adam makes an excellent point about brake performance and monitoring brake heat.  In every instance where I have seen the nylon brake lines fail, they have always been inside tightly fitted wheel fairings.  I have never seen a heat failure on

I think the big takeaways from this discussion are that testing is useful, but one must understand the limitations and failure modes of the system which can sometimes only be determined though testing. In the large airplane world we have numbers for brake cooling time after an aborted takeoff or
