Wut? Aircrack can run off almost any linux distro la. I ran it off *buntu and Debian before. Just build dependencies
What you mean on its own? It is flexible enough to serve other purposes but it really depends on your goal

Uh, whats with the hostility man? I just asked what you want to do with aircrack. But if you are so insecure...... (see I can make assumptions too)

for me, aircrack are good on its own but the complexity made me burst out. I hate to run multiple terminal to sniff,dump,and crack. so i use some automate script todo the task. The more simple and short. Save my precious time. Just run, hunt, wait and pwned. My favourite is wifite.
