RE FCeng84 # 63

The data that we have seen for the Lion Air event shows an AOA bias of approximately 20 degrees body between left and right signals. That could result from the difference in vane angles being approximately 40 degrees.
Interesting - a pic of " typical " AOA Sensor shows 8 holes in post # 58

If 9 holes then 360/9 = 40 degrees but if 8 holes then 360/8 = 45degrees
assuming a plus or minus travel gives either 20 degrees or 22.5 degrees. which IMHO gets close to the constant 20 degree offset noted due to fit it or force it miss- installation ( clocking) .
