The guy who started this thread is asking whether it is worth him doing an FIC being that there are no airline jobs, so he's looking to build hrs fast and earn some kind of a living. Part time isn't going to achieve either of these points. £7k for 5hrs a week flying? Not worth it, and only going to worsen his financial issues.
Yes, flying schools will always be keen to add experienced instructors to their part time list because they are under no obligation to provide flying for them and can use them during busy times.
I've already said my piece, and refer back to my last post.
