I can't believe some of the things that have been said in this thread. It is truly shocking.
We have this online community dedicated to excellence in Naval Aviation, a trade that defines the very essence of hard work and dedication, and yet we are entertaining gripes about the initial requirements for selection to the training command. ea6bflyer is being very polite here ... but obviously the message wasn't clear enough.
So here goes: if you can't hack around 2.5-3.0 GPA while balancing a list of extra curricular activities and side jobs, the military, let alone Naval Aviation, is not for you. [There are some that will get selected with lower GPAs, but I'm willing to bet (having known quite a few of them throughout the training pipeline and in the fleet) they struggled in training and some struggled in the fleet as well.] This is a VERY academic community that demands more than just your best effort. Now, more than ever, there is a consistent demand for aviators to be capable operators of technology that are tactically superior in a number of warfare areas -- not to mention the fact that they are still responsible for balancing many ground responsibilites not related to flying. If you tell me that late nights of studying and ROTC commitments are keeping people from satisfactory grades, then my response is this: the selection process is working.
No matter what your commissioning source, each program is designed to weed out the the non-hackers. And it isn't the last filter, either. You can get all the way to the fleet as a winged aviator and still be deemed unfit to be a Naval Aviator and continue in said role. (Believe it ... there are some that play the flight school game just fine, but never quite make the transition from flying an aircraft to employing a war machine on an actual mission.)
I'm sure there are some reading this that will be offended and take it personally ... but you shouldn't. These are simple facts. And those that will weather all the tests this community has to offer and come out on top will endure far more scathing criticisms on a regular basis.
So, as my favorite RAG instructor once said, "Put your f**king big girl panties on ... the hard stuff is still ahead of you!"
