Cheat Sheet

  1. System Architecture & Data Flow -

    Understand the integrated maintenance data system (IMDS) architecture, which relies on a client-server model and secure DoD networks to track every maintenance action. Visualize data flow like a "fuel line" from data entry to analytics, ensuring you know how aircraft status moves through modules (AFI 21-101). Remember the mnemonic F.A.C.T. (Fuel, Acquire, Catalog, Track) to recall key data flow stages.

  2. Aircrew Debriefing Automation -

    IMDS automates aircrew debriefing by importing sortie data directly from the mission planning system and prompting techs to update discrepancies in real time (AFI 11-202V3). This not only reduces manual entry errors but also accelerates turnaround time. Think "Auto-Debrief = Less Grief" to remember the user-friendly interface that flags unresolved faults instantly.

  3. Work Order & Job Control Codes -

    Become familiar with Job Control Codes (JCCs) and Work Order Numbers - the bread and butter of maintenance tracking in IMDS (MIL-STD-1306). Each JCC maps to a specific maintenance action; for example, JCC 640 = scheduled inspection. Use the "6-4-0 = Check Before Go" rhyme to lock in the most common preventive inspection code.

  4. Trending & Predictive Maintenance -

    Leverage IMDS reporting tools to spot trends in component failures, enabling predictive maintenance and higher mission readiness (SAE ARP 1755). The system's Condition Based Maintenance Plus (CBM+) module aggregates data for real-time health assessments. Remember "Trend, Don't End" to emphasize proactive action over reactive fixes.

  5. Reporting & Analysis Tools -

    Master IMDS's built-in query builder and standard reports (e.g., Mission Capable Rate, Maintenance Indices) to evaluate squadron health (AFMCI 21-101V1). Export data into spreadsheets for advanced analysis, like regression on time-between-failures. Use the 5-2-1 rule: five clicks to get your report, two minutes to export, and one minute to interpret the key metrics!
