Bravo73;
You are absolutely right. We do a mix of corporate/charter here. luckilly it gets you away from just being pilot for one person/organisation, and there is variety of aircraft, customers and jobs on a day to day basis.
Our corporate customers also accept that we operate their machines to public transport standards ie weather minima, landing site size, aircraft performance etc. They also have to accept that the pilot's word is final. No is No no matter how much money you have.
Depending on the aircraft and customer requirements can vary as to pilot experience and qualifications. Our tightest requirements are 3500 hours P1 with IR and 500 hours on type. Normally they want 2500 and an IR. When we took on a new type last year four of us had to get an exemption from the client's rules about time on type because there weren't any to gain experience on. This is going to happen again this year.
Much as I enjoy the work a roster would be nice. Time off can happen on a "fallen off the end of the FTL basis." especially in the Summer. This flexibility is essential in this business to remain competitive whilst maintaining legality. Weekends are unfortunately for others, including your own familly.
There is no way I would want to be dedicated to one customer, especially when new to the situation. It can make for a very unhealthy relationship with the pilot trying to please the boss, or the boss expecting his wishes to be fulfilled.
