A bunch of years back a company I worked for was looking at replacing the Navajos as it was difficult to get 100ll. The number we figured on was 100hrs/month/90 legs, the ho/caravan were equal and we made extra money on anything on top. The PC12 we looked at and used for a 3 week period, and figured if we did 150 hrs on the ho it was cost effective to buy the 12. As we were only doing 120/month on the ho's, company bought a Van and the CP crashed it 3 months later.
