EGATSU-SP case studies
EGATSU-SP · Put your knowledge to work in context.
EGATSU-SP is a specialty credential for practitioners who need to demonstrate structured, end-to-end competence across a full delivery lifecycle rather than depth in a single tool. It suits engineers, consultants, and technical leads whose day-to-day work spans requirements gathering, design decisions, hands-on configuration, verification, and steady-state operations, and who are expected to justify those decisions to reviewers, auditors, and customers. The EGATSU-SP case studies are 5 cases and about 4,307 words.
1The 99.99% That Was Not
During acceptance of a new multi-sensor track distribution system for a terminal area control centre, the supplier's compliance matrix states "availability: 99.99%". The system feeds fused radar and ADS-B tracks to 14 controller working positions.

An air traffic services unit is accepting a new voice communication system carrying controller–pilot communications across 120 positions. The supplier's verification report states that the system has an MTBF of at least 20,000 hours, evidenced by a 500-hour continuous soak test with zero recorded failures, and that all 640 regression test cases pass, giving "100% test coverage".

An approach control unit reports that one display channel, fed by a primary surveillance radar, shows occasional track jumps of 2–4 nautical miles followed by a freeze of one to three seconds. The fault began three weeks ago, appears two to five times per day, clusters between 14:00 and 16:00 local time, raises no alarm, and clears without intervention.
