Should you not as a pilot request a defect repaired as soon as possible, instead of flying with the defect for a long time.

What if a new error occurs and this becomes much more serious because it already has a flaw in the system.
The systems on the aircraft depend on each other and multiple defects may well provide an unintended and unknown effects.
The systems on the aircraft has been designed for optimum safety, every time a system is flawed, its removes a part of safty.
I can not imagine that they will put many additional systems into the cockpit, just because you have to be able to fly for longer time without repair.
And it should be possible for both mechanic and pilot to ground the plane
Defects must be repaired as soon as possible
