Potato's Routebook

Potato's Routebook is a standalone offline airline route planner for virtual pilots. It allows users to create custom airlines, aircraft, and routes on a world map, with each route displayed as a great-circle line showing distance and estimated flight time. The tool includes a database of over 3,000 airports and supports project management and data import-export. Designed for use outside the simulator, it is compatible with Chrome or Edge and does not require installation.
