Acronym Glossary
Alphabetical reference of every acronym used across the AVGS activity models, domain pages, requirement decomposition guide, and presentation. Each entry links to the pages where it appears.
Level of maintenance performed at the squadron — fault isolation, minor repair, troubleshooting.
Requirements management platform used as the system of record for parent-child requirement traceability.
Condition monitoring and predictive analytics that shift maintenance from time-based to evidence-based using HUMS data and RUL estimation.
Approves baseline changes to requirements, architecture, and artifacts after initial approval.
Aircraft status metric — ready to perform at least one tasked mission, though possibly with some limitations.
Urgent modification or inspection directive with a calendar or flight-hour deadline.
Government milestone review where the preliminary design is examined for maturity and risk before proceeding to fabrication.
Onboard device that records flight parameters. Owned by Air Vehicle, not Ground Systems.
Enterprise repository where processed AVGS data is uploaded with provenance, hashes, and access controls.
Government milestone review examining system requirements and preliminary design before detailed design begins.
Digital interactive maintenance procedures used by maintainers in the field.
Air Force regulatory and procedural guidance documents referenced in requirement rationale.
Detects flight events and exceedances from recorded flight data to improve safety and training.
Electric-powered GSE variant adopted by airlines for reduced emissions and noise.
Self-test capabilities on aircraft that generate fault codes and health indicators received by AVGS.
Aircraft data interface point. Ground Systems instrumentation may connect to it, but Ground Systems does not own it.
Plans and manages spares, tools, training, and facilities so maintenance demand can be executed.
Enterprise system anchoring the digital thread across engineering, manufacturing, and sustainment records.
Aircraft status metric — ready to perform all tasked missions with no deficiencies.
System where fault codes, CBM+ alerts, and TCTOs become scheduled, executed, and signed-off work orders.
Leadership role responsible for program execution, cost, schedule, and technical performance.
Organization responsible for overall program direction, funding, and stakeholder coordination.
Aircraft status metric — able to perform at least one but not all tasked missions due to deficiencies.
Handheld or laptop device used by maintainers to access aircraft data on the flight line.
Domain expert who validates intent and definitions. Mohammed and Feras are Reliability Engineering SMEs.
Flight parameter measured in feet per minute. Exceedances detected by MFOQA analysis.
Flight parameter measured in feet per minute. Exceedances detected by MFOQA analysis.
Authoritative maintenance, inspection, and operational procedures published by Tech Pubs.
Onboard aircraft power unit. Ground power units (GPUs) substitute for the APU while engines are off.
Supplies electrical power to aircraft while engines are off. Example: JetGo iBS-28.
Cross-functional team structure used in defense programs to manage requirements by domain.
System or process for authoring, revising, and publishing technical manuals and inspection procedures.
Approves naming, behavior, and allocation changes before requirements enter JAMA. Preserves architectural baseline.
Rolls up aircraft availability, mission capability, and readiness reporting to leadership.
Government milestone review examining system requirements for completeness, consistency, and feasibility.
Gate that authorizes verification activities to begin by confirming test procedures, resources, and entry criteria are met.
Tracks fatigue life consumption, damage tolerance, and airworthiness across the structural lifecycle. Also referred to as 'Integrity'.
Machinery and tools that service aircraft on the ground — tugs, power units, refuelers, deicers, stairs, etc.
Equipment that enables maintenance and sustainment. Includes the Mission System Power Pack Cradle.
Enterprise data backbone tying as-designed, as-built, and as-maintained records together over the asset lifecycle.
Onboard system collecting vibration, temperature, pressure, and oil debris data for CBM+ prognostics.
CBM+ estimate of how much operating time remains before a component requires replacement or overhaul.
Umbrella system that ingests aircraft data on the ground and feeds every downstream analytical and sustainment domain. Sometimes referred to as Air Vehicle Ground Support Equipment (AVGSE).
