Another example of a bad MEL is : autopilot inop along with pressurization in manual mode. IT is hard to fly this plane with the ap out and the other pilot having to work the pressurization wheel manually.
SLF Here...
IMHO MELs exist just to justify the operation of an aircraft which does not satisfy the safety requirements.
How can a piece of equipment (i.e. a/c) can be operated for 10 days, and than grounded because is not safe?
Still in IMHO MELs were created to avoid to ground planes for minor issues, but now are used to keep the planes off the ground as long as possible. Today most of the operators are not looking at MELs as a way to minimize the cost of repair, but as a way to maximise profit.
Still a silly opinion of a SLF
