ASL/DHL overrun LIME/BGY Italy
Weather dude,
I've often wondered how heavy rain has to be before you get more than 3mm of surface water on a grooved runway as we are not supposed to land while that is the case at my outfit. Do you know what visibility in RA equates to 3mm deep of water on a grooved runway? 1500m? 1000m? 800m?
What about on a non grooved runway?

What I don't know what the weight of the airplane does and if you guys always get to the concrete and push all the liquid stuff aside...but for sure the water depth exceeded 3 mm by far.
I ask myself why there is no trend info on the METAR - a BECMNG 31025G35KT +TSRA at 1.50 UTC may have helped - and if ATC looked on the radar at all. And since the pics I posted are from the Swiss radar, question if they have that radar imagery at all.

The a/c would have been light, I assume. Parcels weighting less than pax + baggage.

Thanks for those who commented about the Landing weight. I was wondering if a light weight might have lent itself to floating, especially with tailwind. However, both seem to be discounted, expect a gust/burst from the TS's might have caused a momentary tailwind.
Slightly off the direct topic, but relevant. It has been said many times, and also recently on the Emirates gear collapse in Dubai topic, that all engine G/A's are often the most messed up manoeuvre and the least practiced. Considering the number of overruns from long landings: it is possible in very a/c I've flown to execute a G/A from the runway until the TR's are selected. It is a scenario I have never practiced in 35 years of Boeing flying; yet many overruns could have been avoided by doing just that. Busting the gate at 500' is one thing, flaring and floating is another opportunity to G/A, even after touchdown it is possible to G/A BUT takes huge amounts of courage & awareness to change the mindset of landing. I'm certain that once experienced, in the sim, that doubt/fear would be reduced significantly. Yet, none of my airlines had seen fit to include it in an recurrency training. DAFT. There's a real world out there, but some of the 'training?' does not seem the most relevant.

Spot on. I could convince our training manager, long time ago, to include in one recurrent session a situation that necessitated a GA, well after the decision to land was taken. The results were rewarding, in that it needed to repeated in quite some sessions.
However after T/D it was a different ballgame, as our first action was to aggressively pull reverse. Once the REV handles were pulled back, a GA was not allowed any more. But counting in that the touchdown was anywhere near the TD point.

messed up all engine GA's. (GAs ?)
Yes, having flown mostly long sectors, GA's were rare in my career. From the maybe three I made, only one was AS+ quality. The others soso. Mostly because ATC interfered and amended the published and briefed GA procedure, necessitating altitudes to be reset, headings to be changed. In a time that workload was high, as was the climb rate at light weight.

Not sure if that's real or fake, but made me chuckle - apparently that's the post-accident statement of the driver that was hit by plane...

Double back: I have had the 'mandatory' wave off at 50'. It is a TR training item. It is briefed in advance, but not warned of. It was rarely repeated in training afterwards. In LVO training the 50' G/A using autopilot is a trained manoeuvre. The a/c may bounce but the automatics do not. That's the education.
What has never been done is a G/A after touchdown. That's the training I'm calling for. It's a possibility & reality, so why not trained for.

Looks like the ILS was off.....

I would completely agree as well. I always brief it's one of the hardest manoeuvres we do. Why...because it can be unexpected and it's not sufficiently trained on sim details. It can be due to W/shear...baulked landing...or discontinued approach or a combination (each requiring different mindsets and rapid assimilation) and invariably a startle factor.
I can count the number of go arounds (non training) in my career on one hand.
One of those was recently in perfect flying conditions....
Was fatigue a factor..Yes. Was experience a factor....yes. Was the outcome of the manoeuvre ever in doubt....no.
But and it's a big but, the holes in the cheese are slowly lining up and I'm not alone in that viewpoint.

I would disagree on training that. The most likely cause would be a long landing, but that would be the first mistake then. Landing long and THEN deciding to GA would be two mistakes in a row.
It gets into the field of aborting after V1, even on a long RWY.
