Hi Jacek!
To be precised 100FH is FLM requirement for Cat A as you said. However, if we are going to do an effective trend monitoring definitely better way is increased PAC frequency. EMM recommends to do it every 10FH or less for trend monitoring purposes. The reason is early detection of engine problem or more accurate trend line for example. The more samples the more accurate really engine state I think
PS Probably the same heli
