1. SCOPE

This Technical Supplement (TS) defines the minimum performance requirements of the Family of Maintenance Trainers – Common Core (FMT-CC).

1.1 Overview

The FMT-CC provides the essential common functionality for the Family of Maintenance Trainers Product Line (FMT PL). The FMT PL enables training in critical field level maintenance tasks required for specified tactical and combat vehicles. Maintenance Trainers that are included within the FMT PL provide skill level development for system operation, fault diagnosis, troubleshooting, adjustments, component removal/replacement, and other servicing and repair tasks.

The FMT-CC is a single baseline intended to provide the infrastructure, functionality, and capabilities to support maintenance training on multiple tactical vehicles. The FMT-CC software shall be delivered on standard digital media and installed on Commercial Off The Shelf (COTS) computing and networking hardware. Vehicle specific simulation and training software baselines shall be installed separately on the same hardware, shall interoperate with the FMT-CC, and shall provide the vehicle specific behaviors, fidelity, and data necessary to satisfy training requirements for that specific vehicle.

The FMT-CC software will support training on multiple types of Training Aid, Devices, Simulators and Simulations (TADSS), including desktop Diagnostic and Troubleshooting Trainers (DTTs), Hands-On-Trainers (HOTs), and Part Task Trainers (PTTs). This document is intended to specify training requirements that are common to DTTs, HOTs, and PTTs, and training requirements that are common to all vehicles within the FMT Product Line.

A group of trainers within the FMT PL that provides training on the same vehicle, or any of its variants, is referred to in this document as a Maintenance Training System (MTS). For example, all of the DTTs, HOTs, and PTTs that provide training on a Stryker vehicle variant will collectively be referred to as the Stryker MTS.

Sections in this document titled DTT, HOT, or PTT specify requirements unique to those respective training devices. All other requirements apply to all categories of training devices.
