Was doing a multi rating flight with a student in a crappy old PA23, one engine throttled back, turbulent and he is on the hood, chatting to me and flying the ILS. I actually tapped the OBS because it was locked rock solid both needles centred all the way down the glideslope. I can hardly do this VFR with two engines.
I asked him how he managed it and he seemed to think it was not unusual, since it was something he was doing for years on MSFS.
