[NO BUG]Lighting Mode Switch Ineffective w/o Engine Running

[Captain Orso]

Once you've turned the battery on, the IFEI (Integrated Fuel / Engine Indicator) lights up. However the Lighting Mode Switch will do nothing until an engine is running, and if you start an engine with it set to Nite, you must first switch to Day and then back to Nite for lighting to be effected.

 

Aslo, to the upper left of the IFEI there is a small flood light, which shines down on the IFEI, which I cannot turn off. It's always on as long as the battery switch is on.

iirc the small floodlight turns on with the APU and turns off when the APU turns off, unless I'm thinking of a different flood light.

That's how the 18 is in real life. There is also a flood light that shines on the gages above the right knee. Those lights stay on with either battery power or ground electrical power. They don't shut off till one of the generators cones in line with the engine. And as foe the light mode switch it works that way too. You can have it in night. Kill power. 5 seconds later out power back in and would still have to cycle from night to day and back to night.

Thanks for the replies.

 

Okay, I can see the small lights on the instrument panel to be kind-of emergency lights that are on automatically. However the idea that the Lighting Mode Switch would have special logic to keep the IFEI lighting on Day although set to Nite just because an engine is not running, basically telling the pilot, "I don't care if you don't want the overly bright instrument lighting in the middle of the pitch-black night, you will get what I want you to have", and then not even switch to Nite when the engine is running.

 

Nah, to me it looks like a typical failure to monitor the switch position when the engines are off and when they first start.
