At 60 tons, FL30 the -800 has a Ref speed of 142 kts, so 147 kts with the 5 kts add. With autobrake 3 and 13 kts tailwind and standing water it will stop in 2672 m. The numbers for max auto and max manual are not very much different.
FL40 gives a Ref speed of 134 kts, and 2514 m. IF FL40 was used, a lot of pilots don’t like to use FL40.
These are raw numbers, no safety margins added and standing water on the runway.
Wet performance is very optimistic given the conditions, but FL30 AB3 gives 2191 m and 1717m with max manual.
FL40 AB3 gives 2024 m and 1610m with max manual.
Add about 3 kts and 100 m for 62 tons. The flights from ME to India are often landing weight limited so the numbers would most likely be in the region of 62-64 tons. Less than max since there is not enough space to bring all the luggage that pax want to bring home.
This landing was only possible with wet conditions and a landing at the correct spot.
Standing water. No.
Slippery when wet. Just, raw data only, but not with the required margins. Not even with FL40 and max manual.
