Slide 3

About the C-130J Aircraft First named "Hercules," the C-130 has turned into a legend, with more than 2,100 C-130\'s manufactured and acquired by more than 60 countries in many varieties. The C-130: Carries troops, vehicles, and combat hardware into fight Drops paratroopers and supplies Serves as airborne and ground refuelers Provides crisis and compassionate alleviation (notwithstanding going about as doctor\'s facility ships) Does airborne early cautioning and sea observation (it even flies into storms) First conveyance of the C-130J was to the Royal Air Force The new C-130J resembles the first all things considered, yet it is immeasurably enhanced: 21% quicker, 40% higher, 40% longer range Reduced labor (aircrew of 2 rather than 5), working costs, bolster costs, lifecycle costs another impetus framework (29% more push with 15% more fuel productivity) Advanced flying innovation – 50 World\'s Records!

About the C-130J - Advanced Avionics Technology Four multifunctional heads-down Liquid Crystal Display (LCD) instrument readouts for Aircraft Flight Control Operating Internal Systems Navigation Two holographic heads-up presentations (HUDs) good with night vision imaging frameworks Full-Authority Digital Aircraft Engine Control (FADEC) Two Mission Computers (MCs) and two reinforcement Bus Interface Units (BIUs) give double excess air ship control with coordinated diagnostics The State-of-the-Art Cockpit of the C-130J Ground-Based Data System (GBDS) for flying machine examination and upkeep on the ground More than 50 Computer Software Configuration Items (CSCIs)

Slide 5

Block 2 - the 382J Aircraft The 382J Aircraft is the construct class in light of which the C-130J is based The 382J Aircraft got FAA Type Certification Block 3 - the essential C-130J Aircraft Inherits from the 382J Aircraft Block 2 and Block 3 Domain Engineering was performed since the mid 1990\'s Block 4 - the Variants of the fundamental C-130J Aircraft Unique forms of the C-130J altered for a few clients, including, yet not constrained to: United States Air Force (2 Variants) Royal Air Force - United Kingdom Royal Australian Air Force Block 5 – Maintenance and ECPs and in addition more Variants Customer needs change More clients, for example, Denmark Each Block (and, on account of Block 4 and 5, every Variant) is partitioned into: Air Vehicle CSCIs - give focal figuring (MC and BIU) and subsystem ( e.g ., FADEC) programming on the air ship Support Systems CSCIs - bolster ground-based labs and information accumulation and investigation framework (GBDS) Training Systems CSCIs - bolster preparing the air group and airplane upkeep work force Classes of Aircraft Software

The C-130J Air Vehicle Avionics Architecture Two Mission Computers (MCs) Two Bus Interface Units (BIUs) various air ship subsystem gadgets referred to for the most part as Line-Replaceable Units (LRUs) LMAC has built up the MC Operational Flight Program (OFP) and the BIU OFP CSCIs Perform interconnection and intercommunication between other figuring components Central storehouse for data on the flying machine subsystems LMAC and 26 providers have built up the LRUs and their inner programming The MC OFP and the BIU OFP CSCIs cooperate with the 6 Ground-Based Data System (GBDS) CSCIs created by LMAC Ground Maintenance Program Application Processing (GMPAP) CSCI Ground Maintenance Program Special Processing (GMPSP) CSCI Operational Maintenance Program Mission Computer (OMP-MC) CSCI Operational Maintenance Program Portable Maintenance Aid (OMP-PMA) CSCI Router CSCI Memory Loader Verifier (MLV) CSCI Air Vehicle CSCIs - Introduction

Management of such a perplexing arrangement of programming made by LMAC and a heap of providers is an imposing assignment The administration begins with the Tier I Software Development Plan (SDP): Is the controlling record for dealing with the product parts of the C-130J program Overviews the administration and specialized procedures important to fulfill the prerequisites of the C-130J program Provides bearings for making the Tier II SDPs, gave by LMAC and every provider LMAC has made two Air Vehicle Tier II SDPs - one for the MC and BIU OFP CSCIs and one for the 6 GBDS CSCIs These SDPs address administration and specialized issues, including, yet not restricted to, the issues of: general administration flying machine wellbeing and security programming process definition and administration Requirements-and reuse-situated programming forms have been created as per the LMAC Standard Software Process Framework (SSPF), which is agreeable with SEI CMM Level 3, ISO 9001, and IEEE/EIA 12207 SDPs - Tier I and Tier II

Domain Engineering (DE) is performed on the C-130J program (has been since the mid 1990\'s) The C-130J area was characterized as far as the Air Vehicle, Support, and Training Systems, stressing the MC and BIU OFP CSCIs: MC and BIU Architecture definition was intended to bolster the option, expulsion, and alteration of classes of LRU gadgets to the air ship Design layouts for 5, and now 8, classes of gadgets were made and utilized; today, we call this Template-Based Design (TBD) and utilize the formats to include new gadgets/LRUs Ada-based Design Approach for Real-Time Systems (ADARTS) was utilized to make the formats Requirements-Based Engineering (RBE) is performed on the C-130J program Requirements are characterized in a more exact, particular shape utilizing CoRE (Consortium Requirements Engineering) tables Qualification criteria (testability) for prerequisites is characterized when the necessities themselves are characterized This prompts to Requirements-Based Testing (RBT) DE, ADARTS, TBD, RBE, RBT, and CoRE are utilized with the support of the Software Productivity Consortium (SPC) Software Development and Reuse

Slide 11

Process changes and item lifecycles are overseen utilizing a robotized administer based, shut circle change control prepare driven by the Process Configuration Management System (PCMS) instrument All work items, not simply baselined items, are controlled The program staff are given parts that determine their capacities to influence the items being controlled Parallel improvement endeavors are encouraged (8 C-130J Blocks/Variants are at present in different phases of advancement) Accurate, current, and finish status bookkeeping is a by-result of the utilization of the PCMS-based process The mechanized procedure upheld by device bolster diminishes regulatory support and clerking overhead Electronic Online Software Change Requests (OSCRs) and an electronic Software Development Change Control (SDCC) load up are a key a portion of this procedure OSCRs are controlled like whatever other work item, and they have a lifecycle Process Change and Product Lifecycle Management Requirements Implementation Integration and Testing Submit Code Implementation Analysis Ready for Build SDCC Review Hold OSCR Lifecycle Closed Reject
