Vietnam B789 at Munich on Aug 15th 2026, late rotation, tailstrike, runway overrun, tyre damage

So I've been out of the big-plane game for a while now (11+ years?!? That long?!? Oye!) but I guess most of the big jet operators don't have any sort of acceleration check or similar? Back in the day (apparently WAY back in the day) if Freddy was heavy enough (or runway short enough) and we had to do a standing take-off, we would calculate a acceleration check. Basically after XX seconds after brake release you needed to be at XXX airspeed or well, RTO.

This was used in addition to the normal V1/V2 and all, but a good way to make sure you were going fast enough. I know this was the way with the legacy (TF-39) jets but I don't remember if it carried over the the CF6s.

We don't have one as policy, other than the normal Airbus 100 knots callout (for verifying all three speed tapes are about the same). I've got a series of rough estimates in my head based on weight and FLEX temp for time to reach 80 knots.
