IAE V2500 is a two-spool high-bypass turbofan family spanning the V2500-A1/A5 commercial series, V2500-D5 for the MD-90, and V2500-E5 for Embraer’s C-390 Millennium. IAE and Pratt & Whitney document a 22,000–33,000 lbf family range, A319/A320/A321 and MD-90 service, cargo-conversion applications, and the C-390 military platform; Pratt & Whitney reports more than 250 million flight hours and more than 3,000 aircraft served. IAE’s product table shows model-specific bypass ratios from 4.5 to 5.4, so bypass ratio remains on the model records rather than this family row; exact series and aircraft installations remain separate identities. IAE’s official V2500 product card records a first-flight milestone in May 1988, without establishing an exact day for the family record.
