Oops Typo. Read: With a Hughes Mk2 sextant, you'd lock the top of the azimouth ring with the top lubber line against the aircraft heading and read the relative bearing of the object as indicated by the bottom lubber line. You could do all sorts shuffling between lubber lines: heading checks, airborne compass swings, gyro alignments, lots. DaveP
