Magnetic Variation (MagVar) software update ensures your fleet’s inertial refer-ence systems magnetic variation table is up to date with the Earth’s natural change, avoiding operational limitation by allowing your aircraft to operate safely on precision approaches.
Update your MagVar software now to avoid facing operational restrictions in northern most and southern most airports in North America (Alaska/Canada), Northern Europe, South America and Australia/New Zealand.
Maintaining IRU/ADIRU MagVar is required to avoid aircraft operational restrictions on Auto-land / Auto rollout operations below Cat I ILS approaches.
A major consequence of an out-of-date magnetic variation table is on the lateral guidance during Auto-land (ILS Cat II and Cat III approaches) and automatic rollout.
