A320 Unreliable airspeed and trouble shooting
In the simulator I have noticed that in the process of isolating the affected ADR by using the QRH pitch and thrust tables for a given FL and weight, the resultant speed indicated in the QRH table and the speed indicated by the reliable ADR does not match exactly. Sometimes it's way-off by at least 10 knots or greater. Is there a tolerance allowed? And how will you identify the reliable ADR if the resultant speed on PFD after setting the pitch and thrust does not match the QRH speed?
