[NEED TRACK] ACI configuration check

[thunderstorm09]

Hi everyone!

 

I found that during battery start ACI configuration check (ROLL LEFT, ROLL LEFT) goes normally. But if you use ground electrical power ACI configuration check never happens. Doesn't matter what the map and configuration. I just followed NATOPS procedures. NATOPS says

 

NOTE

 

In aircraft with MC OFP 13C AND UP, MC1 does an ACI configuration check after the generator comes online during a cold start power-up.

 

So, it means, doesn't matter what source you used for start, just generator on line is main reason for this check.

We need a track, please.

Update

 

I found the problem! When I connected the GND PWR switches I applied every switch for 3-4 seconds. If apply only sw №1 for 3-4 seconds and others momentarily – test passes.

 

But!

 

According the NATOPS ACI configuration test should happen ONLY after generator comes on line during cold start, because MC1 does ACI configuration check. Not after Ground power. When use ground power I use switches 1,2, 4 in B position, according NATOPS. This configuration powers MC2. Then turn on R DDI and select FCS–MC page. You can find that both MC1 and MC2 are ON.

That is why "ROLL LEFT, ROLL LEFT" sounds before generator comes on line. This is bug.

 

By the way check please cowers for GEN TIE CONTROL sw and GAIN sw. The switches should go back when cowered. And, GAIN sw in ORIDE position penetrates cower.

 

When both engines are shut down there is no yellow FLAPS light.

My fault, sorry, ground power switch 1 in position B powers both MC. In this case I don't know why ACI test should happen after generator comes on line. Maybe MC1 checks this event. I don't know...
