True, some of the larger aircraft and military jets have an AOA
indicator. Most small aircraft do not have an AOA indicator. There is a
good reason for this. In a large aircraft, the weight can vary
substantially over its flight envelope. This will result in a large
variation in stall speed. In a small aircraft, the stall speed variation
is rather small, and a single stall speed can be used safely.

IMHO, there is no good reason for not having an AOA indicator on GA
aircraft. Stall/spin is a leading cause of death among GA pilots and
passengers. Best glide (potential emergency situation) is determined by
AOA. Put an AOA sensor on GA planes with a hand that smacks the pilot on
the head when the AOA approaches the critical AOA and a lot fewer people
will die while having fun on the weekends.
