FTI means they will pay for up to 100 hours for any requirements you need.
Let’s say you have 25 hours of multi time already, you will get 25 MORE multi time in the training sims for the 170/175. That does not come out of your bonus and is not apart of FTI.
Let’s say you needed 10 hours to get to 25 total multi timehours, then you will find a flight school and Republic will pay up front for the hours required and take it out of the back end of your bonus.
