3 REQUIREMENTS3.1 Required ModesThe trainer will operate in or support various modes. The modes include Lesson Selection, Lecture, Demonstration, Training, and Diagnostics. The Lesson Selection and Diagnostics modes are operator selectable. The Lecture, Demonstration, and Training modes are a common mode of execution but differ in how the instructor makes use of that mode. The characteristics of these modes are addressed in the relative paragraphs of this section.

3.1.1 Lesson SelectionThe trainer shall provide the capability for the instructor to select a lesson. The Training Management System (TMS) maintains a library of lessons that can be selected for training. All lessons for the automotive, Remote Weapon Station (RWS), Anti-tank guided Missile (ATGM), Fire Support Vehicle (FSV), and Mortar Carrier (MC) shall follow Stryker Integrated Electronic Technical Manual (IETM) 9-2355-311-13&P dated 10 December 2015 using Electronic Maintenance System (EMS) Next Generation (NG) viewer v2.1.10 and all lessons for the Mobile Gun System (MGS) shall follow IETM 9-2355-321-13&P with release date of 31 October 2013. Filter options for each TM are defined in Appendix P. The filter options from Appendix P shall be pre-loaded but modifiable by the student. From the Instructor Operator Station (IOS), the instructor can select an appropriate lesson from that library to use for training. Refer to Section 3.2.3.1 Lesson Planning for further definition of the Lesson Planning/Selection capabilities of the trainer.

3.1.2 LectureThe DTT trainers provide a classroom environment where the instructor presents both normal and faulted system functionality. The IOS on the DTT shall allow the operator to optionally select displays for projection on two screens, supporting the instructor’s lecture with high fidelity references to actual vehicle systems and panels. IOS capability shall be provided to:

a. Select normal or faulted operation

b. Select the presentation method (equipment graphics, functional block diagrams, electrical schematics, IETM)

c. Control the lesson (refer to Section 3.2.3 Instructor Capabilities)

d. Project a large screen video display

3.1.3 DemonstrationThe trainers provide an environment where the instructor has the option to demonstrate both normal and faulted system functionality. IOS capability shall be provided to:

a. Select normal or faulted operation

b. Select the presentation method (equipment graphics, functional block diagrams, electrical schematics, IETM)


8


c. Control the lesson (refer to Section 3.2.3 Instructor Capabilities)

3.1.4 TrainingIn this mode, the instructor sets up a scenario for students and observes their progress. A scenario is essentially a virtual representation of the steps required to perform a given Enabling Learning Objective (ELO). The use of the term “scenario” throughout this document is synonymous with an ELO. The trainer mode shall:

a. Support a classroom lockstep mode on the DTTs. In classroom lockstep mode, all of the students must complete the same step in a scenario before any student can move to the next step.

b. Support individual lockstep mode on the DTTs. In the individual lockstep mode, the student must perform all of the operations required by the IETM in the same order as that document describes. There is no interaction with other students.

c. Support knowledge based training by displaying the schematics or system diagram in sufficient detail to allow the student to demonstrate their understanding of the system operation.

d. Provide instructional features and controls to support the learning objectives and instructional tasks during trainer simulation operations. The student workstations simulate the vehicle and support operations of the maintainer.

The default vehicle variant selected on the IOS for an instructor or warrant officer shall be the ICV. The instructor, warrant officer and student shall be able to select any Stryker series variant that will be used for training when running in a Free Run mode. Execution of all training tasks is assumed to be ISA Standard Day. Refer to Section 3.2.2 Training Execution Modes for additional information on supported training modes.

3.1.5 DiagnosticsDuring the loading phase of the computational system, available diagnostics that require no interaction by the operator shall be executed. If all tests are passed, the simulator initialization shall proceed without operator intervention. If any of the diagnostic tests should fail, the simulator shall automatically enter the diagnostic mode. In addition, after the trainer has been initialized for simulation, the operator shall have the ability to enter the diagnostic mode and select from any of the available diagnostics and alignment procedures that have been provided with the COTS system.

3.2 System Capability RequirementsThe Stryker MTS is both a training device and a training management tool. The maintenance training systems shall provide a familiarization, institutional, unit training and skill level development capability for system operation, fault diagnosis, troubleshooting, adjustments, removal/replacement tasks required by the Stryker vehicle systems. A training management workstation, networked, but separate from the training system(s), shall be provided to allow management to retrieve, review, update, correct, delete, archive, and printout selected student performance (by name or ID number) or group performance data. Refer to the Section 3.2.9 Training Management


9


System (TMS) section of this document for a complete listing of the reporting capabilities.

The appendices contain the Training Task List (TTL) listing the troubleshooting and maintenance tasks to be supported by the Phase IV DTT. The maintenance training systems shall provide training for the tasks defined in the TTL. The training system(s) shall provide a library of preprogrammed training scenarios to train the ELOs contained in the TTL. For the automotive related ELOs, the vehicle variant supported for Phase IV training shall be the ICV.

For these preprogrammed training scenarios, the fault symptoms shall be predetermined by the scenario content and shall not be alterable by the instructor. The training system(s) shall simulate faults that require the replacement of one or more LRUs to correct the symptoms, as dictated by the tasks identified in the TTL. Completion of the proper fault response sequence by the student shall cancel the fault symptoms in the simulation.

3.2.1 Fidelity RequirementsThe training system(s) shall train the functional application of the vehicle system through the student interface, providing those external stimuli and visual effects that prompt crewmember action/reaction. The training system(s) shall simulate to an appropriate level of fidelity the features, functions, and performance of the vehicle crew compartment. The vehicle systems to be simulated for required training shall include the following:

a. Remote Weapon Station

b. Anti-Tank Guided Missile (ATGM) System

c. Fire Support Vehicle (FSV) System

d. Mortar Carrier Vehicle (MCV) System

e. Mobile Gun System (MGS)

f. Power Pack

g. Engine

h. Transmission

i. Power Module

j. Pneumatic System

k. Fuel System

l. Exhaust System

m. Driveline

n. Suspension

o. Doors, Hatches and Grilles

p. Cooling Module

q. Central Tire Inflation System


10


r. Pneumatic Brake System

s. Steering System

t. Electrical System

y. Winch Assembly

z. Lighting System

aa. Seating Assemblies

bb. Covers, Guards and Access Panels

cc. Monitoring and Warning Devices

The training system(s) shall simulate the actual vehicle with sufficient fidelity to adequately train students based on simulations of these vehicle systems. All simulated vehicle subsystems and components shall replicate the appearance, function, and application of actual vehicle components as 3-D graphics at the fidelity and level of detail necessary to train the tasks specified in this document. Where applicable, the audio-visual feedback shall replicate the vehicle equipment.

The user shall be given the capability to perform pre-defined ancillary tasks (e.g., road test) in a single action. These tasks are not the focus of the training, but may be required to be accomplished to complete the assigned task. A complete listing of these single action (i.e., Button Task) tasks can be found in the Appendix of this specification.

The TMS shall provide the capability to select Troubleshooting ELOs that do not require the student to perform detailed maintenance actions (i.e., Single Action LRU Replacements) on the DTTs, as dictated by the content of the TTL. Single Action LRU replacement shall account for all steps within a referenced Remove/Install Maintenance Task, including those steps that occur under the "Conditions" and "Follow-on" sections in the IETM for that Maintenance Task. Any LRU replacement that occurs under a Troubleshooting path in the TTL shall be performed as a Single Action LRU Replacement. Upon completion of a Single Action LRU Replacement, the state of the vehicle system models shall reflect any impact that would result from the execution of the Maintenance Task activities accounted for in the Single Action as described above. The resultant state of the execution of a Single Action LRU Replacement, or any Button Task, shall be achieved without presenting any of the transitory states (i.e., graphical transitions, aural cues, etc.) to the user.

To support the objectives of the tasks defined in the TTL, there are certain system parameters that have no impact on the success of achieving these objectives. Those parameters can assume to be constant with no impact on the value of training. The following is a list of such parameters:

Engine oil quantity shall always be at a constant value of full


11


Hour Meter shall display a constant value of accumulated engine operating hours

Odometer shall display a constant value of accumulated distance in miles

Fuel tank quantity shall always be at a constant value of full, when not faulted or drained

The Battery Power Source will always be fully charged at a battery capacity of 100 ampere hours

Maintenance Support Device's (MSD) internal batteries shall have limitless power to support the MSD's normal operation

The training system(s) shall provide the controls, scenarios, visual cues, and sound cues required to train the ELOs identified in the TTL. Scenarios shall be unique, consisting of a set of training tasks to be completed. A scenario can be considered either preprogrammed or free-run. All preprogrammed scenarios for the Stryker MTS are identified in the TTL. A free-run scenario is not listed in the TTL; is not selectable by the instructor; and has no scoring capabilities but will alert the user when a hazardous condition has occurred. For each preprogrammed scenario, the instructor shall be provided with digitized text describing the tasks to be trained and grading criteria of the scenario. The activities of the student(s) and the status of the student’s training scenario shall be available to be displayed to the instructor on a monitor and remote Tablet.

The simulated HMS system shall support the ability to lower/raise the front and back of the vehicle.

3.2.2 Training Execution ModesThe ELOs identified in the TTL will be available for training on the designated devices, as indicated in the list. These tasks (i.e., preprogrammed scenarios) can be run in either a free play mode or lockstep mode. The free play mode allows the student to deviate from the expected path of execution. The lockstep mode prevents the student from deviating from the sequence of steps of the given task as defined in the IETM. The MTS is also capable of running without the selection of any task in the TTL. This is considered a “free-run scenario”. If no lesson is currently active, the trainer defaults to a free-run mode. All students in a class are assigned the same lesson.

3.2.3 Instructor Capabilities3.2.3.1 Lesson PlanningThe training system shall allow the instructor to build a Lesson Plan consisting of one or more Terminal Learning Objectives (TLO). The training system(s) shall allow the instructor to select a TLO and two or more Enabling Learning Objectives (ELO) to build the Lesson Plan. It will provide the Instructor with the capability to further customize the Lesson Plan by adding notes, pertinent to each ELO, either for the Instructors own use or for display to the students. The notes added by the instructor shall be either for display to the student stations or viewable only at the IOS. The instructor will be given the capability to save these customized lessons. The instructor shall be able to view the associated symptom description and scoring criteria (refer to Section 3.2.9 Training Management System (TMS)) for each ELO in the TTL. The instructor will be able to alter the scoring thresholds (i.e., the number of occurrences of given criteria that are allowed before a score of NO-GO is assigned). The Stryker MTS TTL is composed entirely of ELOs. The text for the ELO titles will be pulled directly from IETM.

DTT Class creation shall allow the selection of only those lessons consisting entirely of ELOs from the DTT TTL. Class creation shall allow for inclusion of multiple lessons, each with a different vehicle variant.

A Lesson may include a single or multiple fault scenarios and/or maintenance task scenarios. The scenarios are performed in sequence. That is, one scenario must complete, either by resolution from student actions or instructor removal, before another will begin. Some of these fault scenarios will require multiple LRU replacements to remedy the symptoms. Each of these selectable faults is listed within the TTL.

Lesson creation shall limit the selection of ELOs for the DTT platform to only those available in the current DTT TTL.

The TMS shall provide a mechanism to support coexistence of legacy lessons for the HOT, pre 3D upgrade for the DTT, and 3D lessons for the DTT. At the TMS, during lesson creation, the capability to select a weapon variant shall be part of the criteria for filtering and selecting ELOs. Lesson creation shall only permit a single vehicle variant per lesson.


16
