On the subject of rig take off again.. Today I experienced something not quite usual. Weight was about 9700 kg, OAT 30C with nil wind and nil flaring at the rig.The hover power at 3 to 4 ft low hover was 6.4 FLI, Nr 104. There should be ample power for the take off as I have about 3/4 FLI power margin. Using the take off profile for PC2 DLE when the aircraft was at 15 ft the ROC was only about 100 to 200 ft per min. I brought it down to a very low hover and applied take off power in about 1 sec (" more forceful" ) and I got about 300 to 400 ft ROC. Problem is after rotating there was hardly any ROC ( which is quite unusual) until after Vtoss. Not a very comfortable departure!
I did an EPC on the way back and found the specs to be fine. Anyone here has experienced such a situation before?
