GOV LVL 1 caution is shown on EICAS when FADEC control switch is IDLE or OFF for Level 1 FADEC.

• A. GOV LVL 1
• B. GOV LVL 2
• C. NO CAUTION
• D. GOV LVL 3

Answer: (A)

When the FADEC control switch is in IDLE or OFF, the engine is not being commanded to higher levels, so the EICAS adviser shows which governor level is effectively governing the engine. For Level 1 FADEC, this condition triggers a GOV LVL 1 caution. It’s letting you know you’re in the basic Level 1 governor mode, despite the switch position not actively engaging higher levels. You wouldn’t see GOV LVL 2 or GOV LVL 3 under this condition, and there is a caution because the system is actively informing you of the current governor level; no-caution would be incorrect because the message is specifically signaling the Level 1 status.
