Upgrading legacy avionics systems can be a complex but rewarding task that improves system reliability, functionality, compliance, and maintainability all this with life extension for periods exceeding 10 years. This is a challenging exercise as legacy upgrade can only be attempted by indepth knowledge of legacy technologies that have become obsolete and enabling the system to be brought alive with the current technologies and skills.
Coupled with legacy upgrades offer the distinct advantage of feature enhancements to meet with the growing needs of the aerospace industry and giving extension of life. Replacing LRUs such as Video Tape Recorder with Solid State Digital Video Recording System, drop in replacement of Fuel Flow monitoring units for aero engines, Automated Test Equipment that tests the serviceability of armaments and ammunition that are decades old, extending the life of age old aero simulators with feature enhancements, etc.
