Hi IFLY INDIGO,
As has been said, the loss of tailwind would, everything else being equal, give an increase of IAS.
Did she bounce?
With VS higher than normal, flare needs to be started earlier (higher), and thrust retarded later (as has been said above), unless you are “fat” on IAS. If you realise you’ve left it too late, the only safe option is a go-around, because flaring will dig the main wheels in on the A320, just as on most aeroplanes with tricycle L/G.
A last-moment attempt to arrest the sink with a big burst of thrust is not something I would recommend − even if you are using manual thrust (my preference for most manual landings on the A320). It can lead to all kinds of problems, particularly on a short runway. If you do decide to continue, better to leave the power alone, but, if you have to ignore the “retard” call initially, don’t forget to do it once you are safely on the ground… Many of us have.
Yes, it’s easy for us to be wise while we ponder at our keyboards, or watch you from the briefing room window, but it doesn’t necessarily mean we would have done a better job than you did!
