Boeing 737-300 landing technique
Looking for some insight from experienced pilots of the classic series. The operation I work for has recently acquired a 300 series and the majority of us only have experience on the 200 series and although it is still a 737 I have noticed the 300 has a bit more tendency to float when using the same technique in the 200. A fellow recommended to bring the thrust back at 20 feet and arrest the descent but this is no where in the Boeing from and relying on a audible clue to preform a visual maneuver such as a landing which has so many different variables can pose a lot of problems in my opinion. The technique which works well in the 200 is ease the descent with a slight flare and bring the thrust to idle flying the aircraft onto the touchdown zone but I have found the 300 has a tendency to float while doing this and many pilots in turn bring the thrust back sooner and flare higher causing a long landing. Any insight would be greatly appreciated.
