Penko - to all professional pilots is was a 2700m+ runway (or thereabouts), not 2400m. This is why misleading posts need to be challenged so the thread does not go haywire like so many others.
As to 'braking reports' - yes, ideal to have, but come on everyone! 14kts tail, near max landing weight, close to limiting runway length - is that not enough to decide how to do it in the first place??
Dreamland - the aircraft WILL slow down when 'hydroplaning' if you use reversers. They are actually fitted for more than just 'brake wear'
