FlightCloud · early access

Your aircraft, identified.

Upload flight logs. Get a flight-dynamics model of your aircraft, validated against flight data it never saw, with uncertainty you can trust — and the gains to fly it.

PX4 and ArduPilot logs · Python, MATLAB and Julia clients · built on peer-reviewed system identification

How it works

From a log file to a model you can fly.

  1. 01

    Check your data

    Upload a log. FlightCloud tells you, axis by axis, whether it can identify your aircraft — and if not, gives you the excitation to fly next.

  2. 02

    Identify

    Frequency- and time-domain identification of a physical model of your airframe, with Cramér–Rao uncertainty on every parameter.

  3. 03

    Validate

    Every model is checked against flight data held out of the fit. If it fails, FlightCloud says so instead of handing you numbers.

  4. 04

    Fly it next in early access

    Exports for your simulator and autopilot, and inner-loop gains with handling-qualities metrics — gated by the validation result.

Why trust it

Numbers that say how sure they are.

  • Honest uncertainty. Every estimate comes with its confidence interval — and when the data cannot support a parameter, FlightCloud withholds it and tells you why.
  • Validated, not just fitted. A held-out part of every flight is predicted by the model, never used to build it.
  • Reproducible. Every result is stamped with the exact engine and solver versions: same log, same version, same numbers.
  • Flight-proven methods. Built on the identification methods behind a 600 kg unmanned helicopter's flight control system and our peer-reviewed publications.
from barzin import Client

fc = Client(api_key=KEY)
run = fc.identify("flight.bin", model="quadrotor-x")
print(run.parameters["Ixx"])     # estimate ± std, 95 % CI
print(run.validation.theil_u)    # on held-out data
sys = run.state_space()
