After Sao Paulo it will be interesting to see if there are any common automation difficulties like ground spoilers not activating and no auto brakes. Both reversers were operative on this landing but did they function? They shouldn't have needed reversers to stop but surely needed ground spoilers. I landed a 757 once and one reverser would not operate but still didn't need the last 1,000 feet. Wet runways reduce landing weight some but has never been a big problem. I have landed right before hurricanes and have been cleared to land on 02 but requested 20 because of a wet runway and preferring an upsloap runway with 600 ft extra runway with no wind advantage either way. 02 would have worked too but 20 was safer. I hope to hear from my friend in TGU to get the latest info.
