I was doing some landing practice in the ATR42 in order to try out my new Saitek X52 joystick, I was running the Flight Logger to monitor the landings, I was getting penalised with high load factor penalties. The approach speed was 120kts, V/S 600ft/min, at the flair the V/S was between 150 and 200ft/min, on running the video I made of the landing, the main gear touched down first then I lowered the nose. I do not know why I received the penalty, what are the criteria for determining the Load Factor Penalties???
