As a flight instructor I have noticed that some people get it, and some people don't when it comes to flying an airplane. Im sure any instructor would agree with that. I have students that have soloed at 11hrs and I have other students that will probably never solo. Some people just have the natural ability. When you get hired by an airline, you have to go through ground school just like everybody else, and if you can make it through that, I would think that you are qualified to be there regardless of flight time. Just because you have thousands of hours of flight time, that automatically makes you so much better than a guy with only hundreds of hours?
