HOW IT WORKS TOGETHER
🔗
Unified
Training Flow

All five modules run simultaneously and stay in sync. A typical training session:

  • Step 1 — Instructor assigns a fault isolation task (e.g. ATA29 Hydraulic fault)
  • Step 2 — Student opens Dynamic Schematics to understand the hydraulic system layout
  • Step 3 — Student switches to Virtual Cockpit, reads ECAM messages, runs BITE tests
  • Step 4 — Student consults TSM manual to confirm fault isolation steps
  • Step 5 — Student goes to 3D Aircraft, locates the faulty component, performs the task
  • Step 6 — Instructor reviews completion records and grade is automatically logged

ATA System Coverage

The A320 VMT covers 20 major aircraft system chapters defined by the ATA iSpec 2200 standard — the same chapter structure used in real Airbus maintenance manuals.

ATA (Air Transport Association) chapters are the universal numbering system used in all civil aviation maintenance documentation. Each chapter covers a specific aircraft system — ATA 24 is always Electrical Power, ATA 29 is always Hydraulics, regardless of the aircraft manufacturer.

The A320 VMT allows students to perform 4 categories of training tasks on each covered system, for a total of 265 tasks:

Feature Deep Dive

Four defining capabilities that make the A320 VMT the industry standard for Airbus type maintenance training.

Full A320 Virtual Cockpit

Every square centimeter of the A320 flight deck is faithfully reproduced and interactive. Students can sit in the "captain's seat" or "first officer's seat" perspective, operate every switch and button with the mouse, and watch the real-time system responses — exactly as on a real A320.

The cockpit connects live with the Dynamic Schematics and 3D Aircraft modules. When a student operates a hydraulic valve in the cockpit, both the hydraulic schematic and the 3D aircraft model update simultaneously.

  • P1
    Captain's instrument panel — PFD, ND, engine instruments, all gauges fully simulated
  • P2
    Center instrument panel — standby instruments, ISIS, clock, weather radar control
  • P3
    First officer's instrument panel — mirrored primary displays
  • OH
    Overhead panel — complete A320 OVHD with all system controls (fuel, electrical, hydraulics, bleed air, anti-ice...)
  • CP
    Center pedestal — MCDU, flap lever, speed brake, parking brake, radio management panels
  • CB
    Circuit breaker panels — all breakers individually operable, essential for fault isolation tasks

ELEC Bay Panel
Full avionics bay access for BITE card testing and system diagnostics
CB Panels
Circuit breaker panels — individually clickable for fault isolation procedures

Dynamic System Schematics

Static diagrams in textbooks cannot show students how a system behaves as conditions change. The A320 VMT's dynamic schematic viewer displays every aircraft system as an animated, real-time diagram — with all component states reflecting actual cockpit switch positions.

When a student switches on the left engine bleed air valve in the cockpit, the pneumatic schematic immediately shows the valve opening, the airflow path changing, and the downstream components responding — just like the real ECAM schematic would.

  • Live cockpit sync — schematic always mirrors current cockpit state, in both directions
  • 🔍
    Zoom & navigate — drill into any sub-system component for detail view
  • 🔬
    Measurement simulation — virtual multimeter for resistance, DC and AC voltage readings
  • 📋
    All 20 systems — dedicated diagrams for every ATA chapter, from hydraulics to comms
  • 🚨
    Fault visualization — when a fault is active, affected components shown in red/amber matching ECAM
A320 Hydraulic System — Schematic Structure
Green System
Engine 1 driven pump + E-pump. Powers flight controls, gear, nose steering
Blue System
Engine-driven pump + RAT. Powers flight controls, brake accumulator
Yellow System
Engine 2 driven pump + E-pump. Powers spoilers, cargo doors, PKB
PTU (Power Transfer Unit)
Transfers hydraulic power between Green/Yellow without fluid transfer
Live State Sync
All valve positions, pressures and system modes reflect real cockpit switch state

Fault Injection & Isolation

The most valuable maintenance training exercise is fault isolation — and yet it's the hardest to practice on real aircraft. The A320 VMT lets instructors inject precise faults at the component level, immediately triggering realistic cockpit effects, ECAM warnings and CFDS fault codes exactly as a real aircraft would display them.

Students then follow the actual A320 TSM (Troubleshooting Manual) procedures to isolate and clear the fault. Every step is logged automatically.

  • 42 fault isolation tasks spanning all 20 ATA chapters
  • 🎯
    Instructor injects fault — cockpit ECAM, warning lights and system response are immediate and accurate
  • 📖
    Student uses integrated TSM to follow the official fault isolation procedure
  • 🔧
    3D aircraft model shows faulty component location — student accesses and "replaces" part
  • Post-rectification BITE test confirms fault cleared — system returns to normal
  • 📝
    Full fault-to-clearance record saved for assessment and review
  • ⚠️
    Includes Malfunction fault category — for pilot-reported in-flight fault training scenarios
Fault Isolation Workflow — Example
Fault Injected
Instructor injects e.g. "HYD Green Low Level" via instructor panel
ECAM Warning
AMBER "HYD G LO LVL" message on E/WD. System page auto-displayed. Warning light illuminates.
CFDS Check
Student accesses MCDU CFDS page — fault code recorded with ATA reference
TSM Procedure
Student opens TSM → follows isolation steps → locates faulty reservoir level sensor
Fault Cleared
3D aircraft: replace sensor → BITE test passes → ECAM clears. Task complete. Score recorded.

Classroom Management System

The A320 VMT is more than a simulation tool — it's a complete learning management platform. One instructor can manage an entire class of 24 students simultaneously, with full visibility into every student's progress in real time.

All student actions, session times, fault completions and exam results are automatically recorded to a central database. At semester end, full grade reports can be exported to Excel for institutional records.
