I had this incidence/AOA debate on another forum not so long back.
I think DP Davis's definition of incidence is quite historical and doesn't reflect the accepted modern UK definitions - I did an aeronautical engineering degree here in the UK back in the 80's, and even at that time we were using the now commonly accepted definitions of AoA and incidence, those being AoA is relative to the airflow, and incidence is to some airframe datum.
