LOW OIL PRESSURE Alert
Illuminated (amber) –
.
steady – oil pressure at or below red line
.
blinking – with a condition of low oil pressure. Alert is displayed and solid amber boxes are displayed in unannunciated positions for that engine. All three boxes blink for ten seconds, then alert remains on steady and solid amber boxes are removed (see Note).
OIL FILTER BYPASS Alert
Illuminated (amber) –
.
steady – indicates an impending bypass of scavenge oil filter
.

Note: Blinking is inhibited:
.
during takeoff from 80 knots to 400 feet RA, or 30 seconds after reaching 80 knots, whichever occurs first
.
during landing below 200 feet RA until 30 seconds after touchdown
