Traditional Aircraft System Integration

• Hardware-in-the-Loop (HWITL) System Integration Labs

• Replicates the aircraft with real avionic Line Replaceable Units (LRUs)

• Used for full system development & testing; can “fly” the aircraft

• High Cost & Complexity

• Significant facility space investment

• Extensive hardware, power, and maintenance requirements

• Desktop Avionics System Models

• Software simulations of specific LRUs, designed to allow development of software without utilizing HWITL SILs

• Behavior may be rudimentary or limited to scripted interactions

• Integration of other aircraft systems is typically limited

• A better way: flyable, system-level simulation capabilities available at every developer’s desktop


Prepar3D®

• Commercial-Off-The-Shelf (COTS) Visual simulation platform optimized for training

• Windows-based solution for realistic & affordable simulation and training

• Built around an open architecture, leveraging a mature simulation engine

• Full WGS-84 globe with worldwide terrain coverage and classification

• Weather, AI-controlled air traffic, sensors, weapons, sea states, bathymetry, etc.

• Supports for thousands of entities in a distributed environment (LVC)

• Realistic 3D graphics using technology from the gaming industry

• Can be integrated with other technology platforms – including legacy simulators

• Delivers a full spectrum learning & simulation environment

• Air, land, sea, and undersea training capabilities

• Capabilities range from procedural training to mission rehearsal

Case Study: Sikorsky Avionics Development

• FMS Desktop Simulation integrated with Prepar3D® for Navigation Software Development & Test

• Maximizes use of existing systems with minimal ‘glue code’

• Relieves utilization strain on Hardware-in-the-Loop SILs

• Enables low cost and quick evaluation of complex functions like RNP and TAWS

• ‘A SIL On Every Desk’ – Find and fix bugs earlier in the system lifecycle

Prepar3D®

FMS Sim

PFD & Flight Director Sim


• Benefits

• Non-Recurring Engineering costs are reduced; develop simulation systems & models once

• Better simulation environment for SILs, better simulation fidelity for training

• Increased model & simulation maturity reduces technical risk

• Faster initial training delivery & improved concurrency

• Challenges

• Model Fidelity – SIL & Training do not always share fidelity requirements

• Priorities – Requires close coordination between aircraft & training teams from Day 1

• Funding Profiles – May increase simulation costs earlier in the program than typical

Case Study: RAIDER® Mobile Simulator

• Demonstration platform for X2 Technology® and MATRIX™

• Built using the best of Lockheed Martin SIL and Flight Training Device software products, early in aircraft development cycle

• Includes training features such as a brief/debrief capabilities and a tactical environment

• Realized Benefits:

• OFP team has more realistic environment for pilot HMI feedback, targeting systems, etc

• Training team gets early experience with challenges such as LIDAR correlation


Case Study: Cockpit Procedures Trainers

• LM-100J® Multi-Function Training Aids (MFTAs) utilise Prepar3D® touchscreen interfaces with existing host systems

• SIL-based: OFP & SIL system models, with minimal HWITL

• Full Flight Simulator (FFS) based: FFS host with I/O replaced by P3D

• Provides procedures training, including with flight where permissible

• Customers benefit from reduced NRE, improved concurrency, & Prepar3D® courseware features


Summary

• The Open Architecture and commercial availability of Prepar3D® makes it an excellent option for building both engineering and training simulations

• Lockheed Martin’s vision is for a “Simulation Device Continuum” which blurs the line between Engineering and Training simulations

• Reduced risk & Increased capability for vendors

• Reduced cost & Improved concurrency for customers
