Could somebody please clear up this business about the OAT probe once and for all?
What I have gathered from reading the posts regarding this probe here is:
1. There is OAT probe located at or inside the air intake of the engine which measures the temperature of the air "ingested" by the engine, right?
2. Then there's some heating device which is turned on to heat the OAT probe if the airplane enters icing or low temp conditions to protect the OAT probe from getting clogged by ice and snow and thus producing false readings, right?
So what the mechanic deenergized was the heater, not the OAT probe itself, right?
The OAT was still operational except that if the airplane had entered icing conditions it would have got clogged because it had no heating, right?
