  • Question 610725

    This question asks about a compass directly over the Magnetic North Pole, and gives the correct answer as being that the compass tip will point straight down. However no compass, and certainly no aircraft compass, is designed to allow this. Are you certain that this is the answer in the ECQB? The residual dip would be relatively high, but the compass would certainly not point straight down. The explanation given mentions "a freely suspended magnetic compass" but there is no such thing in general use in any field, let alone the flight deck of an aircraft. Dip would make it unusable for any but scientific purposes investigating the Earth's magnetic field.
