When I was a humble ground engineer with Transmeridian, the CL-44 crews always started the No.2 engine first. This was because No.2 engine was designated as the master engine, and all the aircraft systems could be run from this engine, a useful thing when down route in deepest darkest Africa.
This may have just been company policy, as I have seen other CL-44's from other airlines use a different starting sequence.
