What Is the
B737 VMT?

The CNFSimulator® B737 VMT is an engineering-grade desktop maintenance trainer developed for the Boeing B737-800 aircraft type. It delivers a complete simulation of the B737-800 maintenance environment — cockpit panels, aircraft systems, 3D model and integrated manuals — on a standard PC workstation.

What sets the B737 VMT apart from generic simulators is its deep integration with Boeing's actual maintenance workflow. The system incorporates the FIM (Fault Isolation Manual) troubleshooting procedure, the SIMDIRECTOR guided task system, and simulated specialist test equipment — giving students the closest possible experience to working on a real Boeing aircraft.

  • Built on official Boeing B737-800 authorized dataset — all systems, logic and components match the real aircraft
  • Runs on Lockheed Martin Prepar3D, the same professional simulation platform used by airlines and militaries
  • Single engine configuration: CFM56-7B — the standard B737-800 powerplant worldwide
  • Classroom configuration: 1 instructor station + up to 12 student stations on LAN
  • Compliant with CAAC CCAR-147 / AC-147-04R1 Type II B737-800 type-rating training requirements
B737-Exclusive Capabilities

Four features found only in the B737 VMT, directly derived from Boeing's maintenance engineering methodology:

FIM Troubleshooting

Full Boeing FIM (Fault Isolation Manual) integration. Students diagnose faults by following actual FIM task procedures, using CDU and BITE tools just like a real Boeing technician.

ATA System Coverage

The B737 VMT covers 18 ATA chapter systems defined in Boeing's maintenance documentation standard. Every system supports the full range of training task types: operations, BITE tests, component tasks, and fault isolation.

ATA chapters are the universal numbering system used across all civil aviation maintenance manuals. Each number always refers to the same aircraft system family — so skills learned on the B737 VMT directly map to real Boeing maintenance documentation.

For each covered system, the B737 VMT supports four task categories, allowing progression from system familiarization through to independent fault isolation:

Feature Deep Dive

Four defining capabilities that make the B737 VMT the most realistic Boeing maintenance training environment available in a desktop format.

FIM-Based Fault Isolation

The Boeing FIM (Fault Isolation Manual) is the official Boeing procedure for diagnosing aircraft faults. The B737 VMT is built around this methodology — when a fault is active, students must use the actual FIM task procedure to isolate and clear it, using the CDU and BITE systems exactly as a real Boeing technician would.

This is not a simplified simulation. The FIM tasks are developed directly from Boeing's technical documentation — the same procedures used on real B737-800 aircraft at airlines worldwide.

  • 📖
    Complete FIM integration — fault codes reference actual Boeing FIM chapter/task numbers
  • 💻
    CDU BITE diagnostics — students access maintenance pages, read fault codes, and run tests through the actual CDU interface
  • 🔌
    Circuit breaker isolation — FIM procedures require specific CB pulls; P6/P18 panels are fully operable
  • 🔧
    Component replacement — 3D aircraft provides physical access to the faulty LRU (Line Replaceable Unit)
  • Post-replacement BITE verification — confirms fault cleared and system returned to normal
  • 📝
    Full audit trail — every FIM step taken is logged for instructor review and assessment
FIM Fault Isolation — B737 Example (ATA 73-05-00)
Fault Active
Instructor injects "FUEL FILTER FAULT" — EICAS message displayed, warning lights illuminate
CDU BITE Check
Student accesses CDU Maintenance pages → reads fault code → identifies FIM reference: 73-05-00-710-801
FIM Procedure
Student opens FIM → follows isolation steps → confirms "internal fault" classification → references AMM for R&I
CB Isolation
FIM step requires pulling 2 circuit breakers on P18 panel → install safety collars → install warning tags
Repair & Verify
3D aircraft: remove fuel filter → install new unit → close CBs → BITE test passes → EICAS clears

Circuit Breaker Panel Simulation

Circuit breakers (CBs) are a fundamental part of Boeing maintenance procedures. Most fault isolation tasks require isolating electrical power to a specific system by pulling the correct circuit breaker — then confirming with a safety collar and warning tag before any work begins.

The B737 VMT is the only VMT model with dedicated, fully interactive circuit breaker panel simulation — accurately replicating the P6 and P18 panels with hundreds of individually operable breakers.

  • P6
    F/O Circuit Breaker Panel (P6) — full panel, all breakers individually clickable, labels match real aircraft
  • P18
    Captain's Circuit Breaker Panel (P18) — complete simulation with correct Boeing labeling
  • 🔌
    Pull a CB → affected system loses power → cockpit effects follow (lights, displays, warning flags)
  • 🔒
    Safety collar installation — FIM procedures require collaring pulled CBs before maintenance
  • ⚠️
    Warning tag placement — simulated DO NOT OPERATE tags required by AMM safety procedures
  • CB closure completion — push to restore power after maintenance; BITE test confirms system normal

SIMDIRECTOR Guided Training

SIMDIRECTOR is Boeing's professional task guidance system, integrated directly into the B737 VMT simulation environment. It provides contextual, step-by-step guidance during maintenance procedures — making the system accessible to students at all experience levels without oversimplifying the actual procedures.

SIMDIRECTOR is the primary on-ramp for students new to Boeing maintenance. It teaches the correct procedure while allowing the student to perform each action themselves — building muscle memory and procedural confidence before transitioning to independent AMM-based training.

  • Step-by-step task flow — SIMDIRECTOR highlights the next required action and explains why it's needed
  • 🎯
    Context-sensitive prompts — guidance adapts to current system state and student position in the task
  • Real-time feedback — immediate notification when a step is completed correctly or incorrectly
  • 🔄
    Recoverable errors — incorrect actions trigger guidance back on track without punishing the learner
  • 📈
    Progressive independence — instructors can disable SIMDIRECTOR guidance to move students to AMM-level training
  • 🤝
    AMM alignment — every SIMDIRECTOR step directly mirrors the corresponding Boeing AMM task procedure
SIMDIRECTOR Training Progression
Level 1: Guided
SIMDIRECTOR active — every step highlighted, explained and confirmed. Full guidance.
Level 2: Partial Guidance
Instructor reduces hints. SIMDIRECTOR prompts only on error. Student leads.
Level 3: Work Card Only
Bilingual work card provided. No SIMDIRECTOR. Student follows card independently.
Level 4: AMM Independent
Full Boeing AMM only. No guidance. Professional-level training matching airline standards.

Walkaround Inspection & Task Cards

Every B737 flight begins and ends with a walkaround inspection by the maintenance crew. The B737 VMT replicates this essential procedure — including the ability to inject visual and system faults that students must identify during the walkthrough.

Digital maintenance task cards (航后检查单 and 定检单) are also integrated, allowing students to complete, sign off and submit electronic maintenance records — just as they would in an actual MRO environment.

  • 🚶
