adwjenk, Blinkz,
Total I/F at GYR is 43hrs30 last time I checked the syllabus. Much of this is applied & I stand by my previous remarks.
Instrument flying skills & procedures are the same for both single & multi-engine aircraft so you learn the technique on the single, then learn how to fly a twin & apply the same techniques.
In fairness, there is a good deal of synthetic consolidation back at Oxford so that is the place where the 'local' procedures will be adopted.
