What is the maximum allowable tolerance between the two indicators of the dual VOR system when making a VOR check?
4* between the two indicated bearings of a VORs when tuned to the same ground VOR facility.
Max 2/Dual: 4
When checking the sensitivity of a VOR receiver, the number of degrees in course change as the OBS is rotated to move the CDI from center to the last dot on either side should be between
10* and 12*
Number o/Dots: 10-12
