FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Aviation & MRO Testing
Detect Latent Defects with Fleet Test Data
Learn how to find units that pass every individual limit but carry a latent defect, using a derived measurement and fleet-level control charts.
- Quality & Process Control
Setting Alert Thresholds That Actually Work
Why a fixed yield threshold fails on real production lines, and how a self-calibrating EWMA detector finds the right band for each one.
- Aviation & MRO Testing
Getting Started with TofuPilot for Aviation MRO
Set up the TofuPilot CLI, write a first component bench test, and run it locally in an aviation MRO shop, with no account or proprietary data needed.
- Aviation & MRO Testing
Build a Reliability Case with Test Data
Learn how to turn bench measurements into a reliability case for OEM design changes, using MTBUR gaps, drift trends, and Cpk evidence from TofuPilot.
- Aviation & MRO Testing
Component Test Records for EASA Part-145
Map EASA Part-145 record-keeping and calibration rules to TofuPilot features: test records behind the Form 1, retention, backups, and traceability.
- Aviation & MRO Testing
Track Retest Counts to Catch Rogue Units
Learn how to spot rogue units early by tracking retest counts per serial number, with self-calibrating alerts on abnormal shop visits in TofuPilot.
- Aviation & MRO Testing
Avionics LRU Bench Testing and Analytics
Learn how avionics LRU bench tests work, from induction to release, and how to turn CMM test results into analytics with TofuPilot.
- Aviation & MRO Testing
Reduce No-Fault-Found (NFF) in Testing
Learn what No-Fault-Found means, why units pass on the bench yet fail in service, and how to catch the pattern using your own test data in TofuPilot.
- Test Station Setup
Why & How to Run Test Stations Without Root
Running a test station as root is a costly shortcut. Learn least-privilege setup on Linux and Windows: low-privilege account, scoped hardware access, a service.
- Concepts & Methodology
TofuPilot Framework vs OpenHTF
How the TofuPilot Framework and OpenHTF differ, and how each one plugs into the TofuPilot dashboard and stations for live test data.
- Test Station Setup
Operator Interface with OpenHTF
Build an operator interface for OpenHTF tests: the built-in Station Server, user input plugs, and the richer UI available through the TofuPilot CLI.
- Migrating from Legacy Systems
Migrate a Station from v1.0 to TofuPilot CLI
Move a test bench from the v1.0 desktop station app to the TofuPilot CLI: one-command install, automatic deploys, and a live operator UI.
