Not sure if any of the opinions so far have been from women, but I'll throw my female view into the ring...
I wholeheartedly agree with pretty much everyone who has posted so far - throwing money (or in this case, underwriting loans) at women probably isn't going to encourage more to take up pilot studies. They should be using the money to invest in educating kids (both girls and boys) that careers in aviation are not just for men.
IMO, the bigger barrier is the amount of time needed away from home during studies and then when trying to establish a career, which is very off-putting for (most) women who have aspirations of a family life at some point.
L.H. (speaking as an engineering graduate and PPL student - I love stereotypes!)
