Why DFlight API?

We believe it’s unreasonable to impose cumbersome tasks on a human when those tasks could more readily be accomplished through automation. In milliseconds. Without error.

We also believe it’s unreasonable to expect each and every provider of automation software to separately take on the burden of collecting, maintaining, updating, and ensuring the accuracy of the data necessary to perform these tasks.

With DFlight API you won’t have to. Instead, access the most current, most accurate data available… delivered via REST API for seamless integration in your software.


Whether operating under Part 107 or Part 135, preflight assessment responsibilities remain. LJ Aero’s DFlight API provides the data you need to ensure compliance and mission goal achievability.


Pricing tiers aligned to every stage in your product lifecycle… from initial  exploration through development, testing, launch, and scaling as your user base grows.


DFlight API was created by developers for developers.  We have a comprehensive library of resources to help you integrate DFlight with your mission planning software.
