Departure / Destination

RouteFinder can find a routing between any two officially designated aeronautical 'points'. Such 'points' (also called 'fixes' in our context) may be either:

• Airports, identified by 4-letters ICAO location indicators (e.g. LIRF, EGLL, KJFK)
• Navigation aids (VOR, NDB, TACAN ...), identified by 2, 3, or 4-letters codes
• Waypoints (Intersections) usually identified by 5-letters codes

Airport location indicators are unique worldwide, so you can safely disregard entering the 'country code' when your starting/ending fixes are airports.

However, navigation aids and intersections may have duplicate identifiers (for example, 'BOL' may be Bolsena VORTAC in Italy or Bolinda NDB in Australia). In such case the system needs that you indicate the correct ICAO nationality letters (e.g. 'LI' - Italy, 'YM' - Australia, also called 'country code' in RouteFinder) to resolve the ambiguity. If you don't know the correct code, just go ahead and enter only the fix identifier; the system will then propose several alternatives and you can go back and resolve the ambiguity.
