And: Retracting the spoilers and flaps is part of the "After Landing"-Checklist. So there has to be a reason for that. By the way: He retracted the spoilers a few seconds after disengaging the reverser. This should be around 60 knots. So the speed when he retracted the spoilers was approximately around 40 knots, I think still fast enough. | |
