SAR Grid helps aircrews, ground teams, mission staff, and SAR personnel quickly view and identify conventional CAP search grids across the continental United States. Open the app to a national map of all supported sectional grids, then zoom, pan, tap, or long-press to identify the grid and quarter-grid for any location. GridPlanner displays grid boundaries directly on the map with clear labels and coordinate details, making it easier to brief, plan, and visualize a search area before a sortie or field assignment. Features: - Displays conventional CAP grids for all 37 CONUS sectionals - Shows grid and quarter-grid boundaries on the map - Tap, long-press, or double-tap the map to identify the grid at that point - Use your current GPS location to display the active grid and coordinates - View latitude/longitude details in degrees and decimal minutes - Choose Map, Hybrid, Satellite, or Terrain map styles - Launch ForeFlight with the selected grid as a preloaded route, when ForeFlight is installed - Works with bundled grid data for offline grid lookup SAR Grid is designed as a fast reference and planning tool for SAR operations. It is not a substitute for official mission planning, navigation, aeronautical charts, crew briefings, or agency procedures.
