Help and FAQ

AutoNavlog is a computational aid. Independently verify every number before flight.

How do I paste a ForeFlight route?

On the Route step, paste the ForeFlight or ICAO string (airports, fixes, and airways). IFR airway designators expand to every published fix. Use 4-letter ICAO identifiers for airports (for example KDAB, KPIE).

Where do I find winds aloft?

On the Winds step, click Fetch AWC winds aloft to pre-fill direction and speed from the NWS Aviation Weather Center FD table, interpolated to your planned cruise altitude. You must still verify those numbers against the official AWC FD/GFA product (or ForeFlight) before flight. Time Off (UTC) is required so clock ETAs match a paper navlog.

How do I read the printed navlog?

• TC / MC — true course and magnetic course
• WCA / TH / MH — wind correction, true heading, magnetic heading
• GS / ETE — ground speed and estimated time enroute
• Fuel — planned burn for the leg; remaining fuel is shown in time when fuel on board is entered
• ETA — clock time from Time Off, not a running stopwatch

Can I print or save a PDF?

On Results, use Print / Save PDF. The print stylesheet is landscape paper-navlog format.

What aircraft is supported?

Launch tables are Cessna 172S POH climb, cruise, takeoff, and landing. Other aircraft remain a later addition.
