Thanks to all!!
So I pretty much understood that yes, it will cruise at 100kts only empty and alone and yes I can cruise at 90 with two light pax (well two on) and 3/4-half tank but it seem to push a little.
at 11:20 min of the Mona's video in fact I can see 90kts (which is 93 of tas) at 1500ft and 92% on the MLI and later 73kts at 100% at 7500, so around 85 tas. I think that they were pushing to reach Venice before the night. Of course I can't see if they were flying leveled or in a light climb or descent, so mine are only assumptions.
So the typical mission which is for me 220 nm can be done but it will take around 2h30'-2h40' where an r44 will do that in 2 hours. But al least it can be done talking about fuel and reasonable real life wind.
can be said 80% 80kts, 90% 90kts, low and half loaded and 2 onboard?
An other question come in my mind: If you have to fly over water for 20/30 min during this mission, do you necessarily wear floats? I know that would be better for sure but I don't know how helicopter world thinks about that. I'm in the fixed wing world as you can imagine (+3000hours, but around 3hrs in heli) and with a light plane like a cirrus, for example, I would certainly have no problem to do that flight with an emergency dinghy (and sometimes without). But since there's no space in a cabri for a dinghy and since it's an helicopter I would like to have your opinion.
By the way all the 3hrs are In a r22, so it scares me a little, not when flying to be true (it's really nice to fly) but more when reading... And I think I will enjoy more, in a long term, the no mast bumping option of the cabri and the newer design.
thanks again
