I agree with the last poster ..... In addition, Tyoe Ratings are being done in shorter and shorter timescales so learning in a complex swept-wing jet FFS is a definite advantage IMHO. ATOs that make the MCC a real stepping stone in all respects of reality to real airline operations in the aircraft types the main hiring airlines right now are using, you will have a "step up" to passing the TR. if you don't want to believe me then look at this article from Ryanair about those who fail their courses.... in the main they chose cheap and got exactly that .... FNPT II Kingair course versus realism in required standard and practices in for example, a 747-400 FFS.
In life it seems you get what you pay for ..... and if I were interviewing and I had one slot and two very similar candidates with nothing to chose between them then I would take the one that did the MCC/JOC on the 747-400 over the one who did the FNPT II course. Others will have their opinion but this is mine.
