Avionics

The unit-level registry. Every LRU we characterize gets one folder here, documenting its intrinsic properties — pinouts, signal behavior, bench-test observations, quirks, datasheets. The unit is documented once regardless of how many physical copies are installed or how many airframes carry it.

Aircraft panel/module docs describe where and how a unit is installed; this directory describes what the unit is. The two link to each other.

See ../CONTRIBUTING.md for naming conventions, the file skeleton, and the slot-linking convention used in module READMEs.

Index

Add units here as they're documented. Group by function — the categories below are starters; add more as needed.

Flight instruments

  • e.g. adi-collins-329b-8g — Attitude Director Indicator
  • e.g. rmi-collins-331a-9g — Radio Magnetic Indicator
  • e.g. civa-cdu-... — CIVA INS Control Display Unit
