How To Find True Course On ForeFlight For Precise Navigation

Finding true course on ForeFlight requires understanding the software's aeronautical math engines, route drawing tools, and user interface layers to convert magnetic tracks into true references. Pilots can extract precise true course values by adjusting map settings, utilizing the route rubber-banding feature, or reading flight plan details directly in the navigation log.

Pre-Flight Setup and Navigation Parameter Configuration

Executing precise cross-country navigation within ForeFlight demands proper application configuration before engine start. True course calculations rely on accurate magnetic variation models (WMM) built into the application, requiring user awareness of display settings, chart layers, and flight planning parameters.

• Essential Equipment and Software: iPad or iPhone running the latest version of ForeFlight Mobile (Performance Plus or Pro Plus subscription recommended for advanced routing and winds aloft modeling), active internet or GPS connection for current local data, and a digital or paper backup chart.
• Prerequisite Knowledge and Standards: Clear understanding of the distinction between True Course (TC), True Heading (TH), Magnetic Course (MC), Magnetic Heading (MH), and Wind Correction Angle (WCA). Familiarity with FAA or ICAO flight planning standards and Isogonic lines.
• Estimated Setup and Execution Duration: 3 to 5 minutes for route construction and data extraction during pre-flight planning.

Step-by-Step Procedure to Extract True Course in ForeFlight

Step 1: Build the Active Flight Plan

Open ForeFlight and tap the Maps tab to access the flight planning drawer on the left side of the screen. Enter your departure and destination identifiers in the Route field, followed by any intermediate waypoints, fixes, or airways. Once the complete route renders on the moving map, tap the Route button within the drawer to open the detailed flight plan editing view.

Pro-Tip: Always enter your planned cruising altitude before evaluating navigation numbers, as ForeFlight uses altitude-specific winds aloft to calculate true airspeed, groundspeed, and wind correction angles.

Step 2: Access the Navigation Log

Inside the flight plan menu, tap the NavLog (Navigation Log) tab at the top of the window. The NavLog breaks down every leg of your flight into discrete rows, displaying departure and arrival fixes, distance, estimated time en route, fuel burn, and specific directional vectors. Locate the column designated as TC, which represents the True Course for each individual leg of your flight plan.

Warning: Do not confuse True Course (TC) with Magnetic Course (MC) or Magnetic Heading (MH). The TC column specifically lists the track over the ground relative to True North before any wind or magnetic variation adjustments are applied.

Step 3: Utilize the Map Measurement Tool for Direct-To Vectors

If you are flying off-route or need to find the true course for an ad-hoc direct-to vector between two arbitrary points on the map, employ the touch-measurement tool. Tap and hold two fingers simultaneously on the map, connecting your departure point and destination. A direct line will appear displaying the exact distance, magnetic course, and true course directly on the screen annotation.

Step 4: Examine Route Leg Details via Rubber-Banding

Tap on any route leg line drawn across the map to trigger a pop-up menu containing specific segment metrics. Dragging the route line (rubber-banding) to avoid weather or airspace will instantly update the underlying flight plan parameters. Review the pop-up data box to verify the updated True Course value for the newly modified path segment.

Technical Comparison of Navigation Vector Metrics in ForeFlight

Common ForeFlight Navigation Failures and Field Fixes

• Discrepancy Between Displayed Courses:

  
  
  
  • Root Cause: The application is set to display magnetic headings based on user profile preferences, causing confusion when comparing against true course references in flight planning documents.
  • Actionable Fix: Navigate to More > Settings > Units & Time, and verify your True/Magnetic preference settings to ensure the correct north reference is active for your operational requirements.

• Outdated Winds Aloft Affecting True Vectors:

  
  
  
  • Root Cause: The tablet lacks an active internet connection, forcing ForeFlight to rely on stale or missing winds aloft data for vector calculations.
  • Actionable Fix: Connect the device to cellular data or Wi-Fi momentarily prior to flight, pull down on the Maps or Flights page to force a refresh, and ensure the weather sync completes successfully.

• Missing NavLog Columns:

  
  
  
  • Root Cause: The flight plan drawer is minimized or compressed, hiding detailed columnar data like True Course and Ground Speed.
  • Actionable Fix: Expand the flight plan view into full-screen mode or swipe horizontally across the NavLog table to reveal hidden performance and vector metrics.

Frequently Asked Questions

Can I change ForeFlight to display all map routes in True North instead of Magnetic North?

Yes, you can configure ForeFlight to reference True North across the application interface. Go to More, select Settings, locate the Units & Time section, and change the Heading or North Reference setting from Magnetic to True to align all displayed vectors with true measurements.

Why does the True Course differ from the Magnetic Course on my route?

The difference between True Course and Magnetic Course is determined by magnetic variation, which is the angular difference between True North and Magnetic North at your specific geographic location. ForeFlight automatically applies the World Magnetic Model to calculate this difference based on your route's coordinates.

How do I find the true course for a custom user waypoint not listed in the database?

You can drop a user waypoint on the map by pressing and holding your finger on the desired location, then naming the point. Use the two-finger measurement tool by tapping both the origin and your new user waypoint simultaneously to display the exact true course of that custom vector.

Does ForeFlight account for annual magnetic variation changes?

Yes, ForeFlight updates its underlying cartographic and magnetic databases regularly in accordance with the World Magnetic Model (WMM) updates issued every five years, ensuring your magnetic variation offsets remain accurate for precise flight planning.
