The amount budgeted for the modernization of Air Force avionics systems is far short of the amount needed to pay for upgrades already approved in critical areas: performance and safety-mandated upgrades; avionics upgrades required for the global air traffic management (GATM) system; and replacements for aging avionics subsystems with the lowest reliability and/or highest repair costs.

Partly because of "stove-pipe" management structures, organized around individual weapon systems, AGING AVIONICS IN MILITARY AIRCRAFT management responsibility for dealing with the aging avionics problem is fragmented. The committee found little evidence of cross-program, cross-platform, or cross-service coordination in the Air Force.

Implementation of MOSA would be facilitated by addressing the following needs: . development of a common understanding of MOSA support for development of MOSA building codes, and disciplined design processes and related design tools required for MOSA implementation development of a test/requalification strategy coupled with the proper modeling and simulation tools to implement the MOSA strategy economically development of design-reuse databases and highfidelity avionics models by original equipment manufacturers and suppliers Business Issues Finding 14.

From page 42... ...
The Air Force software and hardware testing community should develop a testing/ requalification strategy tailored to modular avionics systems and should explore methods, including the use of high-fidelity simulation/emulation models and test beds, to minimize the impact on cost and schedule of requalifying avionics components and systems. The Air Force should build on the test strategy and simulation/ emulation/diagnostic software model used by the Federal Aviation Administration in the commercial sector, which recognizes the value of reusing hardware/ software and provides certification-test credit for reusable modules.

, by reinforcing its leadership and management responsibility for reducing the total ownership costs of new and legacy avionics systems. l he new Aging Aircraft SPO could become the starting point of an Air Force-wide enterprise strategy for addressing the aging avionics problem.

From page 44... ...
The Air Force should recommend that OSD form a joint cross-platform working group (JCWG) at the flag officer level to focus on reducing total ownership cost through the joint development of modular, scalable systems and the use of common solutions across weapon system platforms.
|
From page 45... ...
The Air Force should recommend that the Office of the Under Secretary of Defense for Acquisition, Technology and Logistics restrict applicability of the Joint Technical Architecture (JTA) and mandated standards to interplatform inter45 operability and allow the intraplatform standards to be defined by a MOSA approach, along with a greatly reduced number of mandated standards.
