Retard
Very interesting topic.
In gusty conditions a late "retard" seems reasonable.
I made note of the auto pilot's landing technique and copied it.
The aircraft approaches at about a 3 degree nose up attitude, the thrust levers go to idle by 30 ft, at 15 feet RA increase the nose up attitude to 6 or 7 degrees (from 3 degrees) and lock it there (except for wing down into the wind if necessary). Always a good landing.
Something else to consider is the fact that modern FAN engines don't just stop producing thrust when the engines go to idle. The free spinning N1 Fan produces about 75 % of the thrust in flight and coupled with "flight idle" thrust continues to propel the aircraft even after closing the thrust levers. Note the longer float distance on most landings today.
I actually start slowly closing the TL at 50 ft to be at idle by 30 ft and then as above. Works for me. It also tends to reduce the landing roll.
New pilots tend to severely overcontrol the aircraft between the threshold and touchdown when all they need to do is position the attitude and lock it there as stated above. The aircraft will land itself with no further help except in very windy conditions.
Thanks, Thermostat.
