Throttles to idle at 50' and flare at 30' just until the end of the runway is barely in view or slightly out of view (depending on weight). How can you teach some one how to land a wide-body over the internet?
Also, much easier to do a smooth landing at Flaps 35. I only ever used Flaps 50 on short or slippery runways. But of couse, follow your companies procedures.
