Fred28 Posted January 25, 2022 Report Share Posted January 25, 2022 (edited) 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 ?

Pils Posted January 25, 2022 Report Share Posted January 25, 2022 How many units of pitch trim are you using? Quote Link to comment Share on other sites More sharing options...
Fred28 Posted January 25, 2022 Author Report Share Posted January 25, 2022 I set the trim at 3 as mentioned in check list Quote Link to comment Share on other sites More sharing options...
Pils Posted January 25, 2022 Report Share Posted January 25, 2022 Can you screenshot the checklist you referring to, please? Trim would usually be roughly 5-6 units for average weights. Quote Link to comment Share on other sites More sharing options...

Pils Posted January 25, 2022 Report Share Posted January 25, 2022 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. 1 1 Quote Link to comment Share on other sites More sharing options...

JRBarrett Posted January 26, 2022 Report Share Posted January 26, 2022 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. 1 Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
