Just to round up the data that was shown on the earlier posts, I have added the S92 masses to those which have already been provided.
Just in case you do not wish to read the other posts, the figures are:
For the S-92:
Taking ISA SL conditions the following masses are provided by the graphs:
Take-off:
The Pure PC2 mass is 26,250lbs
The PC2e mass with an unfactored wind of 20kts is:
26,500lbs for a 50ft drop down
Zero drop down is achieved with an unfactored wind of 30kts
Landing:
The Pure PC2 mass is 26,500lbs
The PC2e mass with an unfactored wind of 20kts is:
26,500lbs for zero drop down
Zero drop down is achieved with an unfactored wind of 20kts
The answer to my question about the endurance of the 225 with 19 passengers appears to be about 2:18 endurance (plus 10% and final reserve fuel).
