I am a student at Aerospace Aviation, and it is true what Zap Brannigan stated, check for student to instructor ratio, because there will be days where it is a good day, but no instructor, even though there are planes.
I started studying at Aerospace Aviation in November, and only getting out 6 hours, but it is not only instructors, most of it has to do with the weather, but 10% of the times, it was instructors.
I can not comment on which school is better as I have only started in this area, but compared to Basair and Aerospace aviation, from what I have seen and know, Basair has been having the most accidents since I started flying and 2 from what I know have been fatal (which is a sad loss), and 1 injured.
I do admit there are a lot of Indian students out there (not a racist remark!)
