Show me how you can turn a profit with a 4-5 million dollar 9 seat aircraft that requires a cheque for 100K everytime a TV burns out, and I'll answer your question.
Thanks for you informative answer. By the way, a fully equipped PC-12 costs $3.2 million ($4.1 million Canadian) and $100K would replace all of the EFIS tubes (if Bearskin was so equipped).
As for turning a profit, why buy them in the first place if won't turn a profit? It's not like there are any hidden costs associated with the purchase or operation of a PC-12. And the expensive avionics can be under warranty for as long as seven years.
