"Config stab" warning during take off

[Fred28]

Hello
 

Despite using the check list, I regularly get a warning message during taking off.
When accelerating, I get a red CONFIG STAB message until the wheels leave the track.

Probably a mistake of mine, but don't understand what it could be. 

Any idea ?

Regards,

How many units of pitch trim are you using?

[Fred28]

I set the trim at 3 as mentioned in check list

Can you screenshot the checklist you referring to, please? Trim would usually be roughly 5-6 units for average weights.

Ok, I see where the confusion comes from. That doesn’t meant 3 units of stab (pitch) trim, it means set the 3 types of trim, i.e. pitch, yaw, and roll.

OK . I feel really stupid 

Thanks for your help

As long as the trim is set within the green band on the trim indicator on the MFD, you will not get the config warning. To calculate the exact setting for takeoff you would need the official Bombardier performance manual, but in most scenarios a trim setting of around 6 units will work fine.

however, I was still in the green zone.

At minimum value, but value still written in green

Perhaps the developer needs to look at the depiction of the green band on the display - it may be too wide. In any case, a trim setting between 5 and 6 seems to always work well.
