Magnetic declination is the angle between magnetic and true north at Earth's surface. Magnetic north points to Earth's magnetic field lines, true north to geographic North Pole. Declination is positive east of true north, negative west
Wingtip devices reduce drag and improve aircraft efficiency. They increase lift-to-drag ratio without significantly increasing wingspan. Winglets prevent wingtip vortices and improve aircraft handling. They reduce wake vortices and improve safety for following aircraft

Plane travel is among safest modes of transportation. Up to 80% of aviation accidents are attributed to human error. In 2007, 6.84 crashes per 100,000 flight hours occurred. Private flights have lower accident rates but harder to document
Pre-flight inspection includes checking control surfaces, fuel, and emergency supplies. Weight and balance sheet must be completed before takeoff. Propeller inspection is crucial before engine start
