I had something as simple as an IDG Low Oil Pressure warnings at rotation on the 320 and it was a major distraction. Every time I cnx the warning it came right back on until I leveled out and the oil covered the sensor. Lights, bells, trying to communicate with each other and ATC was problematic.
In an A320?
Surely that warning would be suppressed during take-off?
And why not use the Emer Canc button if it wasn't?
