-40C is not a hard number for the RJ. That's bulk fuel temp. I've flown -65C before. We lived. Dont ever trust a dispatcher.
After reading this thread, all I can say is: I stand by my signature line.

Oh, yeah urflyingme?!...
You should either clarify your statement or stop telling people your tale altogether. Keep in mind, this thread is discussing the TAKEOFF temp limits of the CRJ.

From the CRJ-200 PRM Vol 2: "Minimum ambient temperature approved for takeoff is -40*C (-40*F)."

The same temp limit applies to starting a cold-soaked APU on the ground.

Now let's visit the "bulk fuel temp" limits: "Takeoff with the bulk fuel temperature indications below the limits stated is prohibited.
Bulk Fuel Takeoff Limit-Minimum Temperature (ASTM D1655, Jet A): -30*C.
Bulk Fuel Freezing Point (ASTM D1655, Jet A): -40*C.

During flight, bulk fuel temperature must remain above the applicable bulk fuel freezing point."

So, in relation to what the OP posted, -40* actually IS a hard number for departures in the CRJ.

Pilot to NTSB ALJ (trying to appeal his/her 90-day suspension)

"But, the dispatcher said it was OK."

Both are enjoying a well-deserved vacation on a beach paradise somewhere.
