Oil Temperature Gauge for Rotax 912 display

[Tuiliere]

Hello,

I read that on the Skyview pilot's user guide :

Oil Temperature Gauge for Rotax 912:
When OIL TEMP < 190oF, the OIL TEMP gauge displays these ranges:
[ch61623] 100-120 and 230-266oF in YELLOW
[ch61623] 120-190oF in GREEN if OIL TEMP has been above 190oF “more recently” than OIL TEMP was
below 120oF; otherwise 120-190oF is displayed in BLACK OUTLINED IN WHITE
[ch61623] 190-230oF in GREEN
[ch61623] 266-280oF in RED.
When OIL TEMP is > 190oF, the OIL TEMP gauge will display different ranges:
[ch61623] 100-120 and 230-266oF in YELLOW [ch61623] 120-230oF in GREEN
[ch61623] 266-280oF in RED

Can you explain me why the oil temp gauge is displayed in black outlined in white when the oil temperature has not been above 190°F "more recently" ? What is the reason of this feature ?

The Rotax operator guide requires that you go above 190F every flight. This is to boil the water out of the oil. If the band is green, you have done this on this flight.
