Anti Skid Inop Light

[Fiddler]

This light is on continuously from power on to shutdown. Wondering if I'm doing something wrong, or if it's a bug.

Thanks!

I'd say its something you're doing wrong. I've not experienced this issue.

The manual says that the anti-skid is powered by the DC bus, so check that your bus ties, inverter etc. are switched on.

Are you on yellow hydraulic system for braking or are you on green?

[Fiddler]

on Yellow. Everything else is working correctly so I doubt its the bus ties, inverters etc but I'll verify. Thanks.

Both YELLOW and GREEN can supply an anti skid function to the single set of brakes on each main wheel. The yellow system also has an EMGY brake function and BAT selection that have no anti skid function.

A few things could be wrong. If hydraulic pressure is OK, check that the ANTI SKID switch is selected ON (not BATT). Also, try selecting the other brake system to that in use. If the INOP indication still remains lit I would suspect a software error or a selection within the EFB.

The EMGY Brake switch (on the centre console) in EMGY Yellow position or ANTI SKID switch in the BATT position would not be expected to cause either a FAULT or INOP indication, but it would cause cause a loss of ANT SKID function.
