Tolerance on A321 ?
When i did a instrument checked and i know that the tolerance between 2 NDs is 4 degree . But we also checked on the stanby compass . Sometimes it exceed 4 and i could not find the tolerance for stby compass ( on FCOM )
Another question when we are under radar control during approach , what is the maximum speed we can exceed ( select on pfd ) folowed by atc speed clearance ?
