Dommage! Yes, my first guess is evidently wrong...
Like lurkio, I notice that the speed target runs up to 172 kt and then remains at that speed, which as he says is VFE(full)-5. But I do not think this can be a GS-MINI speed target, because that would imply that the IRS has detected a sudden headwind-component of 35 knots or more.
So for my second guess!
I think this may be a SRS final target speed, catering for a go-around. But I've never seen such a low SRS target displayed. Normally it is 250, IIRC. But of course one is not looking at that kind of minor, transient detail when preparing to turn off the runway.
I realise it should not make any difference, but - just for interest - is the video of a simulator or an aircraft?
