Influences Due to Temperature Changes

Changes in the temp­er­a­ture of the stack, due to shift­ing of the wind and force of draft, vary its mag­net­ic char­ac­ter­ist­ics. Cons­e­quent­ly the Mag­netic Com­pass is af­fected.

Temp­er­a­ture changes do not in­flu­ence the Sper­ry Gy­ro-Com­pass.

No mat­ter what the con­di­tions are that change the mag­net­ic char­ac­ter­is­tics of the stack, ship or cargo, they can­not af­fect the Gy­ro-Com­pass, as it has noth­ing what­ev­er to do with mag­ne­tism.
