Hi,
I just have my 70hrs PIC done and also need the xtra 30hrs to get 100PIC TT.
I have started the multi engine training and once I have done the required min 6 hrs in the plane, providing my instructor thinks I am good enough for a test sign off, I will then do my multi IR. After that, I will combine my multi Ir skills test with a multi engine skills test, giving me 40hrs in the sim and an additional 15hrs min in a twin before I do the handling skills test of the multi.
Most reckon that after 6/7 hours in a twin, it is unlikely that you are proficient enough in aircraft handling to do a good skills test, so by combining the two, you give yourself more time to be comfortable in the multi. After that, the shorte CPL training is much shorter and also in a single engine, much slower etc., should make for an easier flight test. Also, IMHO, I reckon that if you can do a single engine approach/missed approach procedure under the hood, the examiner at his discretion may well decide that a certain part of the class rating will also have been covered, thereby possibly reducing the amount he may want you to demonstrate VFR for the class rating.....makes sense?
Good luck anyway, I know how you feel about doing another 30hrs, I think I'll just chip away at it whilst doing the rest of the training. A few hours here and there going to various airports should keep your planning/nav skills up to date for the CPL, so it is no harm to have a few hours left to do.
Just to confirm is it 10hrs or 15hrs for the CPL after the IR?
