You asked for an iPad 4 last month, but the guy in the red suit brought you a mini. You want to visit him to discuss his error, so you plan a trip to the airport closest to the north (magnetic) pole: Resolute Bay. But, when you open the approach plates, youre confused.
Near the Earth's poles, magnetic compasses become unreliable due to the magnetic field's characteristics and rapidly changing variation, posing significant navigational challenges.
To address this, high-latitude aviation employs non-magnetic course references: true courses (e.g., used by NAV CANADA) and grid courses (e.g., used by the FAA north of the Arctic Circle).
Grid navigation, developed post-WWII, overlays a non-converging grid that simplifies long-distance polar flight by allowing pilots to maintain constant headings, facilitated by gyroscopic heading indicators and GPS units set to the grid reference.
