Q: I cannot get the condition levers to move out of ground idle. When I move the condition levers to max, they just jump back down to ground idle. Without being able to advance the torque, the plane is not flyable. Any assistance would be appreciated to solve this problem. Thanks.
A: You must perform the Start locks procedure as it is mentioned on the normal checklist.
Check this video, it is for DO228-100, however, is the same procedure for C441 as it has Garret engines as well.
