Overview System Instruments Flight EIS Hazard Avoidance Calm 5 Knots 10 Knots Wind Direction 15 Knots 20 Knots 50 Knots Wind Flag Winds Barbs SURFACE PRESSURE This feature displays pressure isobars and pressure centers. The isobars connect points of equal pressure. Pressure readings can help determine weather and wind conditions. High pressure areas are generally associated with fair weather. Low pressure areas are generally associated with clouds and the chance of precipitation. Isobars that are packed closely together show a strong pressure gradient. Strong gradients are associated with areas of stronger winds. Pressure units can be displayed in Millibars (mb) and Inches of Mercury (in). CNS Interface GPS Navigation Flight Planning Hazard Avoidance Additional Features Integrated Autopilot Annun/Alerts Appendix Other Legend Surface Pressure Data XM LIGHTNING Lightning data shows the approximate location of cloud-to-ground lightning strikes. A strike icon represents a strike that has occurred within a two-kilometer region and within the last seven minutes. The exact location of the lightning strike is not displayed. 182 Garmin G3X Pilot's Guide 190-01115-00 Rev. F Index
