Airport Operations & Ground Handling Systems

The software that keeps an aircraft airworthy, and the planning tools that decide how many spares an air force buys, are bought once a decade and are already owned by the companies that do the maintenance. This record covers maintenance, repair and overhaul (MRO) systems of record — maintenance tracking, work orders, parts and engineering records for airlines, MRO shops and military fleets — and the defence sustainment layer above them: spares optimisation, life-cycle cost and readiness analysis. IFS is the broadest incumbent: Aerospace & Defence is one of its named focus industries, it reported more than EUR 1.2B of total revenue for 2024 and was valued at over EUR 15B in an April 2025 minority sale in which Hg became co-control owner alongside EQT [A]. The commercial MRO specialists have already been taken in by their customers' own industry. AMOS, which Swiss-AS says runs 10,000+ aircraft for 270+ customers, became a 100% subsidiary of Lufthansa Technik — one of the largest MRO providers — in 2023 [C]. AAR, an MRO and parts group with FY2026 sales of $3,308.0M, bought Trax for $120.0M in cash plus up to a $20.0M earn-out in March 2023 (about 5,000 aircraft supported) and Aerostrat's long-range maintenance planning for $19.0M in August 2025 [A]. Veryon (formerly Aircraft Technical Publishers, founded 1973) has rolled up Flightdocs, CaseBank, Rusada (ENVISION), RCMBT, EBIS and, in September 2026, Polaris Aero, and says it serves 5,500+ customers [C]. Ramco Aviation is the one listed specialist, but inside a company with only $71.09M of FY2025 income and a net loss of $4.08M [A]. On the defence side the money moves through sole-source renewals and ERP programmes, not open competition. The US Air Force has used PTC's Servigistics since 2017 to plan what PTC called a $76B service-parts supply chain; a 2022 contract was worth up to $95M over five years, and it was renewed again on 15 October 2026 under the ESCAPE programme, terms undisclosed [B]. Systecon's Opus Suite (OPUS10, SIMLOX, CATLOC) lists the US Navy and Air Force, French and Brazilian air forces, Australia's and Singapore's defence ministries and primes from BAE Systems to Saab among its users, and was bought by Swedish private-equity firm Monterro in April 2025 [B/C]. The Army is consolidating five logistics and finance systems, GCSS-Army among them, onto a single SAP platform under an eight-year Other Transaction award to Accenture Federal Services (initial $69.4M) [B] — while the Air Force's Oracle-based ECSS was cancelled in 2012 after about $1B was spent [B]. That failure is why defence buyers stick with what works. How this differs from its neighbours: 4811 airline operations covers passenger service and the airline IT estate (Amadeus, Sabre); 481214 covers business-aviation flight operations and maintenance tracking (CAMP, Veryon's Part 91/135 side); 336-PLM covers design data; 333 covers industrial predictive maintenance. This record is the MRO shop's and the military fleet's system of record and the sustainment planning tools on top of it. Distribution decides it: a few hundred airlines and MRO shops plus a short list of ministries, each changing systems about once a decade, with airworthiness approval, export-controlled technical data (ITAR/EAR), defence cloud accreditation (ATO, FedRAMP) and CMMC in front of any new entrant — and the independent specialists are already inside MRO groups, a PE roll-up or a large ERP vendor.
