A true 0/0 takeoff (real not simulated) is an accident waiting to happen. If the DG happens to start precessing madly while you're rolling you will be mowing runway lights by the time you realize something's wrong. Or if the AI rolls over shortly after breaking ground you will be dead. And that's in a single. Lose an engine in a twin on or near the ground with no forward visibility and you're just as dead. I'm not opposed to a foggles takeoff but the CFII should make it clear (mine didn't) that this is a skill builder not preparation for the "real thing".
Yep, caged it but I had a few hundred feet. Ended up shooting an ILS into OAK to 90' as they had an ILS. It wasn't quite 0/0 at Hayward, but there were times between centerline dashes that I couldn't see paint. Just a lesson learned, never depart an airport you can't get back into and no Low IFR SE.
