Industry · 04 / Drones & UAS

Every flight, every airframe, one logbook.

ESC currents, IMU bias, FPV video and GPS from the whole fleet — correlated automatically, reviewed in minutes.

01 · Phloem for UAS

Flight review that keeps up with the flight line.

When a fleet flies dozens of sorties a day, review has to be automatic — not an evening with a folder of flight logs.

Reports on landing

Every flight lands with a structured summary — envelope, events, anomalies — delivered before the battery is swapped.

Catch drift before it bites

Trend IMU bias, vibration and ESC temperature across airframes and flag the outlier early.

One incident, whole-fleet answer

Search every flight for the same signature and know in seconds whether it’s one bad motor or a design problem.

02 · Lifecycle

One platform, from first prototype to fleet.

The record built in development carries into validation and operations — nothing starts from scratch.

01

Develop

  • Bench, HIL and flight-test data on one timeline.
  • Compare tuning revisions across identical missions.
  • Trace faults from ESC to autopilot in one view.
02

Validate

  • Fly qualification matrices as repeatable, scored suites.
  • Codify envelope limits once; every sortie is checked.
  • Build regression sets from real in-flight events.
03

Operate

  • Capture the operational fleet, sortie after sortie — heavy streams trimmed at the edge so field uplinks stay thin.
  • Alert on off-nominal behaviour mid-flight.
  • Trend component wear per airframe for smarter maintenance.
03 · One timeline

What a run looks like in Phloem.

A sortie as it lands: battery current, FPV video, attitude and GPS, already on one playhead.

Thin uplink

Heavy streams get trimmed at the edge before they ship, so a field radio link carries the insight — not the bulk. The full-rate record still lands.

04 · Ecosystem

Native to the autopilot stack.

First-class ingest for the formats, protocols and buses this work already runs on — and the wider ecosystem behind them.

05 · Outcomes

What teams get back.

Dozens
Sorties a day, reviewed

Flight review scales with the operation because it starts automatic and stays searchable.

Early
Drift caught fleet-wide

Cross-fleet trending finds the failing motor while it’s still a maintenance item, not an incident report.

06 · End of run

A fleet that reports for duty.

Every sortie writes its own record. Phloem turns the pile of flight logs into one logbook the whole team reads.
