Oil temperature exceeding 185°C (overheat) or oil pressure below 140 psi.
2
Q
At what oil temperature and pressure does the IDG fault light activate?
A
Temperature above 185°C or pressure below 140 psi.
3
Q
What happens when oil temperature exceeds 152°C?
A
An ECAM advisory (green pulsing) is triggered.
4
Q
What are the two ways IDG oil is cooled?
A
1- Air/oil cooler – Maintains oil temperature below 105°C using an ECU-controlled air valve (spring-loaded open in case of failure).
2- Fuel/oil cooler – Keeps IDG oil inlet temperature between 70°C and 105°C.
