I actually really appreciate your questions and applaud your concern. There seems to be this perception that the hardest part of flight training is getting the loan and the rest is a given. The reality is not everyone can (or should) be a pilot or an instructor. So let’s get to some answers:
1/2) I put your questions together because they’re interrelated. If you cannot complete the instructor standardization (which if you completed the training successfully shouldn’t be a problem) you will not be an ATP Instructor. The standardization is not just the curriculum but it’s evaluating you as an instructor. Soooo if you complete the standardization chances are you will not be a terrible instructor, right? But back to your concern there are in fact other means to build time. There’s another thread about a program Mesa Airlines is offering which looks interesting as well as other cargo or charter ops. While instructing provides a tremendous amount of experience and is generally one of the fastest methods to build time, it’s definitely not the only one.
Angel I don’t think you’re being negative just realistic and personally I think that’s a really good thing. It’s always good to have your eyes open and be aware of possible issues that can arise. I believe that helps keeps you sharp and more important will help to motivate you to do well. Based on your questions alone I feel confident you’ll do well.
