I am currently the training officer for a small 135 outfit in North Texas. We recently finished a recurrent training course for all of our pilots. During the course of the training I was explaining how to identify the final approach fix on an ILS:
Final approach fix=glide slope intercept at the published altitude on the approach plate (lightning bolt)
One of our pilots insists that the FAF on the ILS is glide slope intercept no matter what your altitude, in other words if you intercept the glideslope 20 miles out at 5000 feet, that is your final approach fix.

He also insists that this is the way he was taught at two of his previous employers, one of them being American Eagle.

Is this how American Eagle and other airlines, regional or otherwise, teach final approach fix on an ILS?

Any comments are welcome,
IJ
