Lets not tarr all hour builder FI's with the same brush
Mike, we are not tarring them all with the same brush, I was very carefull to point out that there are a lot of good hour building instructors out there. And as you point out these are people who have an airline job and have come back to teaching. I know a lot of first class instructors who do this.
However my experiance which is quite extensive and apparantly that of many other people looking at the forums is the the sub standard far outweighs the high standards.
RVR, you are still missing the point, hours building as an FI gives you diddle advantage in getting an airline job. It is a myth perpetuated by those who don't get a job as a reason for not getting one. FI work for those who do get a job is just marking time deluding themselves that working in aviation is going to give them an advantage. They don't want to be there. Read my comment about my 280hr friend who got a job with BA. Never worked in avaiation and not an FI, but a professional manager and a 1st class team worker.
