Maybe its viewed in that light in Pcola because of the vast number of students they have to complete. And the time requirement isn't set by the flight school, its a Navy directive. The instructor you get helps a lot with that mindset as well. My instructor at PAC was awesome and really made it fun.
It is an attrition program, hence the title "Introductory Flight Screening" and not something super nice and bubbly like "Introductory Flights So guys will do better in primary". It is a cheap and easy way for the Navy to weed out guys and gals who think that flying "just isn't for them". As quoted above, it is up to the school and more specifically the instructor as to whether they treat it as a Naziesque attrition tool or as more of a "lets teach this person for 25 hours and let them decide whether this is for them". I think the kinder, gentler method is probably more appropriate for that level, but I am not 60 years old and teaching in a 172.
