AOA fixed-pitch propeller
Could an expert please help me understand whether we reference TAS or IAS when considering the angle of attack of a fixed-pitch propeller blade?
I have both Bob Tait and ATC text book, Bot Tait refers to TAS and ATC refers to IAS.
I would think TAS is correct because we are only looking at the speed of the relative airflow, note the pressure, but I am very confused and can't really come to a conclusion I can understand.
Thank you
