we fly 135 on raytheon's certificate, as well as 9 others on the certificate. then there's charterops with 3 and talon air with a couple more.
so i know of 17 beechjets currently flying 135, and someone suggested not to even think about it???
5000 ft is a good rule of thumb, but what other jet is going to operate out of less than 5000 in a 135 environment?
