2) North of 70° North latitude between longitude 70° W and 128° W
3) North of 70° North latitude between longitude 85° E and 114° E
4) South of 55° South latitude between longitude 120° E and 165° E
Loss of heading may occur outside of these geographical limits.

IFR operations are prohibited in areas where the magnetic variation is greater than 99.9 degrees East
or West.
