Test condition:
DigitalDesign ULLI -7 ℃
with or without GSX deicing
From Cold and Dar to APU bleed start  engine

A330-300 RR all 5 test no work
A330-300 GE  all 3 test work
A330-200R all 2 test no work

 After I change temperatur to +0℃,  all RR engine work
I didn't know the RR engine was so sensitive to temperature. The icing assist is ONLY VISUAL.

By the way,I know that FENIX's model aircraft has an engine icing simulation feature, requiring a certain thrust to be maintained for a period of time after starting in a cold environment until the ENG VIB drops. I've tried this many times with FENIX.

But on the 330 RR, I don't know how to do it.
