Whilst almost correct Blue robbin i believe the single engine and multi engine IR's are both 50 hours if you have a cpl or 55 hours if you don't. I thought you had to have 15 hours in the aircraft so as long as you have that you can make up the rest of the hours in the fnpt2, however blue robbin seems to suggest that you can only have a max in the sim and it looks like he has referred to lasors so i would tend to go with the max amount of 35 in the fnpt2
