But, if your plane has flaps that deflect much, the "approaching stall angle" for flow relative to that fixed probe changes. A bunch. I would hazard a guess that if your plane has flaps that go 30 degrees or more, and you set the "warning" point for adequate warning with thermaling flap, it will never go off with flaps 30 or more. The calibration shifts whith flaps.

Not saying it can't provide some warning some of the time, but if your ship has flaps, expecially larger deflection flaps, this 5 hole probe is NOT going to do what you want it to without some flap position input to the system for sounding the alarm.

That's my nickel's worth (Inflation, Neal.) :-)
