Hazard Advisor is a ForeFlight map overlay that visually highlights terrain and obstacles relative to a selected altitude, using color coding (red/yellow) based on the chosen Hazard Altitude. This feature helps pilots assess potential hazards before and during flight. Hazard Advisor is available with ForeFlight Pro Plus or higher subscriptions.
Key Features
The following are key features of Hazard Advisor:
- Preflight Hazard Analysis - Analyze terrain and obstacles along a route before flight. Use the altitude slider on the right side of the map to set the Hazard Altitude and visualize potential hazards.
- Profile Corridor - Display a Profile Corridor showing obstacles near a route of flight. The Profile Corridor shows the highest terrain and obstacle for each leg of the route. Set Corridor Activation to Automatic to display the corridor whenever the Hazard Advisor or Profile View is visible, or set it to Show to display the corridor at all times. Adjust the Corridor Width setting to determine how far laterally from a route the corridor will extend.
- In Flight Hazard Advisor - When the GPS speed is greater than the activation speed, Auto Mode activates, and the selected altitude automatically changes to reflect the GPS altitude. Nearby obstacles within 1,000 feet of GPS altitude are shown on the map. The Profile Corridor displays obstacles along the route in real-time.
NOTE: The Corridor Width setting controls the lateral distance from the route centerline in which terrain is shown in the Profile View. Both terrain and obstacles are shown within the Profile Corridor.
Requirements
The following are required to use Hazard Advisor:
- Subscription Level - A ForeFlight Pro Plus or higher subscription.
- High-Resolution Terrain - Must be downloaded for accurate terrain and obstacle display.
