Question

When an aircraft flies into the sanity one of the magnetic poles____

Answer 1

• When an aircraft flies into the vicinity of one of the Earth's magnetic poles (either the North Magnetic Pole or the South Magnetic Pole), it can experience certain magnetic effects. One of these effects is that the magnetic compass on board the aircraft may become unreliable.
• Near the magnetic poles, the Earth's magnetic field lines are nearly vertical, which means that the magnetic compass needle can become nearly horizontal, making it difficult for the pilot to determine their heading accurately using the magnetic compass alone. This phenomenon is known as "magnetic dip" or "magnetic inclination."
• To address this issue, aircraft in these regions often rely on other navigation systems, such as gyroscopes and GPS (Global Positioning System), which are not affected by magnetic variations and provide more accurate heading information.
• Pilots are trained to use a combination of these instruments to navigate safely when flying near the magnetic poles.
