Just about all of my students are professionals in other industries. Most have high expectations of themselves as that is what helped them achieve what they have. I encourage them to relax that expectation with regard to their beginning flight training. The learning curve is quite steep at first and having greater than reasonable expectations can impair their ultimate goal.
I don't think they are quite ready for the ATP ride. But they certainly have a good taste of what instrument training will be like and a healthy respect why they need to obtain it or stay far, far away from those conditions.
In the beginning, I draw a realistic goal of around 55-65 hours. That's the national average. But, I try to build it around some of the extra tasks I want them to accomplish such as added night flights for landing practice, etc. The added XC time includes stops to make it more like the hundred-dollar burger run so many will be making after certificated. Well, it's actually the hundred-dollar brisket run. I've yet to find anyone fight me on that goal.
On average, they may pay 2-4 grand more than some schools. I do stress the benefits in the end for being better prepared. The students I have are sold on this. Also, I'm pretty generous with my time when sessions are at the end of the day or there is no student afterward. Giving time I don't charge for brings me credibility when I charge for the time that is scheduled.
I've had only one student think I might be holding them back. The real problem was his relaxing and simply working through situations. He would jump rather than review what is happening and what needs to change such as sudden change in frequencies for comm and nav while losing a known and verified source. He sought out the help of another instructor who had him doing the same thing... slow down, review, make the change then inspect for what is expected. Two weeks later, he passed his checkride. The week before that, he gave me a check for a grand thanking me for getting him to where he was. I was also his final sign-off for the practical.
Do they pay more? Yes. But, they get plenty for what they are paying for. I've been around a ticket mill and will never agree to operating like that. I pride myself on seeing the student prepared and confident to accomplish any given task.
