Virtual Maintenance Trainer
The first engineering-grade desktop simulation system for China's homegrown C919 narrowbody. Built on the official COMAC authorized dataset — full CCAR-147 compliance from day one.
The CNFSimulator® C919 VMT is purpose-built for type-rating maintenance training on the COMAC C919 — China's first domestically developed narrowbody airliner. It delivers the same engineering-grade simulation fidelity that airline MRO engineers require, in a desktop system that any CCAR-147 institution can deploy.
High-bypass turbofan delivering N1, N2, EGT, fuel flow, oil pressure and vibration simulation. Full FADEC simulation with complete trial run task library per C919 AMM Chapter 71-00. Engine fault scenarios include hung start, hot start, engine fire, oil pressure loss, high vibration and EGT exceedance.
China's first domestically designed and manufactured civil aviation narrowbody, certified by CAAC. Seating 158–192 passengers in single-class config, the C919 competes directly with the Airbus A320 and Boeing 737 families.
The VMT runs on Lockheed Martin's professional-grade Prepar3D simulation engine — the same platform used in military and commercial aviation training worldwide. All C919 system behaviors are modelled against the official COMAC authorized dataset.
Every component model, system logic sequence and maintenance procedure is derived from CnTech's formal COMAC dataset authorization. This ensures full fidelity to the actual aircraft — task numbers, part numbers, and system behavior are aircraft-accurate.
Designed and validated against the CAAC C919 type-rating maintenance training syllabus. Meets all requirements for AC-147-04R1 Type II practical training, enabling institutions to satisfy CAAC without access to a physical aircraft.
The COMAC C919 represents a landmark in China's civil aviation industry — the country's first independently developed and CAAC-certified narrowbody airliner. As airlines across China begin receiving C919 deliveries, the demand for qualified C919 maintenance engineers is growing rapidly. CCAR-147 institutions need a certified, high-fidelity training solution now — not when real aircraft become available for training use.
The CNFSimulator® C919 VMT fills that gap. It is the only desktop maintenance simulator purpose-built for C919 type-rating training, using the official COMAC dataset — not reverse-engineered data.
The C919 VMT is a tightly coupled five-module system. Every module shares a common real-time simulation state — an action in the cockpit instantly propagates to the schematics, 3D aircraft and work card tracker.
Comprehensive classroom management hub for the instructor. Controls the entire training session from a single screen.
The student's entry point for all training activity — personal account, task reception and session tracking.
Three-layer live schematics covering all 20 ATA system chapters — continuously synchronized with cockpit state.
A complete 3D simulation of the C919 flight deck. Every panel, switch, knob, selector and display is modelled and fully mouse-operable.
Full exterior and interior 3D model of the C919 for maintenance task execution, plus the complete integrated C919 manual library.
All five modules run simultaneously and stay in sync. A complete C919 fault isolation session:
The C919 VMT covers 20 major ATA system chapters — the same chapter structure used in C919 airline maintenance documentation. Every chapter supports up to four task categories: Operations, Testing, Disassembly/Installation, and Fault Isolation.
ATA (Air Transport Association) chapter numbering is universal across all civil aircraft. ATA 24 is always Electrical Power, ATA 29 is always Hydraulics. The C919 VMT covers all key systems that appear in the CAAC AC-147-04R1 C919 type-rating syllabus.
Four task categories are provided for each covered ATA chapter, for a total minimum of 305 training tasks:
Four core simulation capabilities that set the CNFSimulator® C919 VMT apart from conventional training aids.
The CNFSimulator® C919 VMT provides a complete 3D simulation of the COMAC C919 flight deck. Every panel, switch, knob, selector and display is modelled against the official COMAC dataset and fully mouse-operable. The cockpit is the central state engine — any change here instantly propagates to all other software modules.
The Dynamic Schematic Viewer covers all 20 ATA system chapters with three complementary diagram layers that update continuously in real time. Students see the direct relationship between cockpit actions and system behavior — replicating the diagnostic process used by working engineers.
The fault simulation system allows the instructor to replicate any failure condition a maintenance engineer might encounter on the real C919. Faults take effect within one simulation cycle and produce exactly the same cockpit indications, ECAS messages, and system behavior changes as the real aircraft fault.
The engine trial run module follows the C919 AMM procedure sequence from preparation through shutdown. Students train on the complete LEAP-1C trial run task library — normal runs, power checks and fault scenarios — without requiring a real aircraft on the ramp.
The C919 VMT is structured to support the full CAAC CCAR-147 type-rating curriculum — from initial system familiarization through advanced fault isolation and formal examination.
Students begin with cockpit panel familiarization — locating and operating all switches, selectors and circuit breakers across P1, P2, P3, P5, P6, P7 and P18 panels. Bilingual work cards ease the transition to English-language technical documentation.
Instructor assigns system overview tasks using the Dynamic Schematic Viewer. Students learn to read Logic, Structure and Wiring diagrams for each ATA chapter before performing hands-on tasks. The live sync shows how cockpit switches control system behavior in real time.
Students complete all 55 Operation-category tasks across 20 ATA chapters. Each task follows an AMM-referenced work card. Task completion is recorded automatically in the LMS. Instructor monitors progress from the instructor station in real time.
The CNFSimulator® C919 VMT is designed and validated against all applicable CAAC regulations and technical standards for C919 type-rating maintenance training.
Complies with CAAC (Civil Aviation Administration of China) approved training organization requirements for Part 147 type-rating maintenance training. Satisfies the AC-147-04R1 Type II practical training syllabus specifically for the C919 aircraft type — the most current regulatory framework for this new-generation platform.
Meets the Chinese civil aviation industry standard for maintenance simulator grading. Grade B requirements cover simulation fidelity, system accuracy, fault modeling capability and operational safety features — the same standard applied to A320 and B737 VMT systems, confirming consistent quality across the CNFSimulator® product line.
Developed exclusively on the official COMAC C919 authorized aircraft dataset. CnTech holds formal COMAC authorization certificates confirming the legitimacy of the data source. All task numbers, part numbers and system behaviors correspond directly to the actual C919 aircraft documentation used by airlines and MRO facilities.
Regulatory approval ultimately rests with your institution's CCAR-147 authorization. The C919 VMT provides the simulation tool that satisfies the practical-training requirements — your school's existing CAAC approval covers the training activity. CnTech provides official dataset authorization certificates and simulator compliance documentation to support your institutional accreditation process.
