So.....today I'm up with my instrument student who busted his checkride for not monitoring the ADF ident during the last minute of his NDB approach. There is an NDB approach to 03L at KSFF but it's one of those on the airport navaids were the navaid is the only IAF and no step downs. In my mind you have to fly over the NDB and do the full procedue on an approach like this. Approach refuses our request for the full procedure but offers vectors to the final....but there is no FAF. I'm thinking...this is gonna be interesting. We'll, the guy just vectors us to final and tells us to call the tower and that's it. Is this legal? Standard practice anywhere else? Now....I could see if approach verified your position as within 10 NM of the navaid, you would be okay to drop down to the MDA. (he never gave us our position) Also, we were VFR doing practice approaches....which might make a difference. Anyway....just wondered what you all thought...I hope I explained it okay.
