Yes you need the hours, but really, nobody should be getting near to those figures which is positively unhealthy. Apart from the health thing, what standard of instruction are your students receiving when you are working 80+ hours per month?
After a two year stint as an instructor the hours will have looked after themselves and you will not be bitter and twisted....like me.....
Any more than 1000 hours of single engine piston flying is a waste in terms of airline selection. Other bells and whistles such as
100 hrs multi minimum is more appreciated by most airlines.
