The left and right side indicators have got out of alignment! They are not really accurate to more than about half a division anyway.

are these indicators out of alignment in all 737 fleet? and also it writes in our sop that there's a 0.5 unit difference and the captain's side must be the one that should be set correctly.

It is my understanding (737-300) that the F/O's side is the master side and if there is any miss-match the F/O's side should be set to required trim! (within limits of course!)........
I stby to be corrected!

If the FCOM or FCTM makes no mention of which stab trim should be set as a master then there is no master. Amazing how chief pilots come up with these little gimmicks and opinion becomes fact
