Typhoon was found guilty of taking on fuel like a complete big-girl's-blouse! Flow rate is pathetic. AAR pipework added as an afterthought, and consequently worse than that in a cheap central heating system.
As no one else has risen to Mr. B's bait, I cant let that go, as it's all shhh*te. AAR designed in from the outset, (OK, EAP didn't have it).
The retractable probe is a wonderful piece of engineering and works as designed on the production aircraft.
