S76C+ OEI cruise datas.
I am looking for realistic cruise OEI figures on S76C+ at ISA+15°C from SL to, let's say 5000 feet at operating weights ranging from MTOW to 10 000 lbs....the ones I have, seem to be a bit optimistic in terms of TAS and fuel cumsumption ( average of 110 Kts IAS and 460 lbs/hr not varying too much with ZP and weight)
These data usually give a better ratio FF/TAS ( wind effect and G/S apart) than wiyh AOI, but I am a bit reluctant to rely on these numbers.
This is basically to work out OEI PNR and diversions, a "return of experience" would be welcome.
Thanks.
