This was an OCU fly2 trip where the student captain gets to land the aircraft on 3 engines - the only time he/she will do it for practice. The QFI sits in the RHS. The only other time an engine is shut down for practice is during QFI workup or for QFI currency (once every 12 months).
The aircraft was on the TAC to ILS runway 25 at Brize, which comes within a few miles of Abingdon, and was at 2300' QNH so about 1900' agl.
Thanks for your interest!
