Route, profile, time and optional fuel in one request.

Flight Time Engine API
Flight planning intelligence, ready for your software.
Generate operational routes, account for forecast winds, avoid restricted airspace and estimate flight time and fuel through one structured API.

}Built for
Flight departmentsCharter platformsTrip supportDispatch systemsAviation softwareOne call. Operationally useful output.
Move from airports to a usable flight plan in seconds.
Flight Time Engine turns concise operational inputs into consistent route and timing data. It gives software teams more than a great-circle estimate without requiring them to build and maintain a flight-planning calculation stack.
Provided route, airway route or direct path.
For automated quoting and planning.
Ready to display, store or pass downstream.
A broader planning result
Core calculations your aviation workflow can use immediately.
Route generation
Generate direct or airway-based routes between ICAO airports, or calculate against a route supplied by your application.
- Direct routing
- Airway routing
- Provided route parsing
Wind-adjusted timing
Apply forecast conditions against the requested departure time, flight level and speed.
- Departure-time dependent
- Climb, cruise and descent
- Mach or TAS input
FIR avoidance
Exclude flight information regions when operational, commercial or geopolitical constraints require it.
- ICAO FIR identifiers
- Multiple FIR exclusions
- Avoidance-aware route
Fuel planning
Add aircraft fuel parameters to receive trip fuel values alongside route and timing.
- Optional fuel model
- Trip fuel estimate
- Integrated result
Flight profile
Represent the full flight rather than treating every route as a single cruise segment.
- Climb profile
- Cruise level
- Descent profile
Integration-ready data
Receive predictable JSON for customer estimates, analysis and system automation.
- Stable structure
- Readable errors
- Portal request history
From input to result
A straightforward workflow, built for automation.
Define the flight
Send airports, level, speed and departure time.
Apply constraints
Select routing, exclude FIRs and add fuel assumptions.
Run the engine
The service resolves route, profile and timing.
Use the response
Display, store or connect the structured result.

Where it fits
Built for decisions that happen before the aircraft moves.
Charter quoting
Produce route-aware time estimates early in the sales process.
Operations dashboards
Add calculated time, distance and routing to internal tools.
Workflow automation
Trigger calculations from booking, CRM or scheduling systems.
Scenario analysis
Compare departure times, routes, levels and FIR constraints.

Questions, answered
What teams ask before integrating.
The full documentation contains every input, example and response field.
Open documentationWhat information is required?
Provide departure and destination ICAO codes plus the relevant performance inputs. Time, level, speed, route preferences, FIR exclusions and fuel parameters make the result more specific.
Can the engine generate the route?
Yes. Leave the route empty and select airway or direct routing behavior.
How do I avoid an airspace region?
Provide ICAO FIR identifiers in the avoid_firs array. Multiple FIRs can be supplied.
Does departure time affect the result?
Yes. It selects time-dependent atmospheric data that can change groundspeed and flight time.
Can fuel be calculated too?
Yes. Supply the documented fuel parameters to return a fuel estimate with the route and timing.
Is direct access different from RapidAPI?
The engine is the same. Direct access includes company accounts, key management, request history, analytics and billing controls.
