Chop your 360 up and see where you can get the bits...
can you get say 10h/m in aerial work, 10h/m charter, and 10h/m scenic.
As the 360 is your lower level, build in some safety, demand 420 or so per year.
If you plan to scrape by, you'll scrape by at best. It's not easy especially if you have well entrenched competition, as they will raise barriers quick smart, and you'll need a heap of wedge to get over them.
You need to put some metrics in place to build a model of what you require for success.
i.e. I need a resort with 50k visitors per year, and a local population of at least 80k, difficult surface travel etc etc etc
Make the descision based on numbers not emotions.
Good luck.
