High performance and complex aircraft endorsements, governed by 14 CFR 61.31(e) and (f) respectively, remain foundational qualifications for pilots seeking to transition into higher-performance piston and turbine-adjacent aircraft. The complex endorsement requires demonstrated proficiency in an aircraft equipped with retractable landing gear, flaps, and a controllable-pitch propeller, while the high performance endorsement mandates ground and flight instruction in an aircraft exceeding 200 horsepower. Indiana presents reasonably strong options for obtaining both, anchored most prominently by Purdue University's aviation program in West Lafayette, which operates one of the largest university-affiliated flight training fleets in the country and has historically maintained access to qualifying aircraft such as the Piper Arrow and Cessna 182RG variants. Regional flight schools affiliated with fixed-base operators at Indianapolis Executive Airport (TYQ), Indianapolis Metropolitan Airport (UMP), and Gary/Chicago International (GYY) have also historically offered these endorsements, though aircraft availability fluctuates with fleet age and maintenance cycles.
The practical challenge for pilots pursuing these endorsements in 2026 is one increasingly felt across the national training ecosystem: the aging and attrition of complex piston aircraft. The Piper Arrow, Beechcraft Bonanza, and Cessna Skylane RG platforms that have historically served as complex trainers are now decades old, and many training operators have reduced or eliminated their complex aircraft inventories due to maintenance costs and insurance pressures. This has created localized shortages in some markets, compelling pilots to travel regionally or arrange instruction through individual aircraft owners willing to provide dual instruction in their personally owned complex aircraft — a legally permissible arrangement under 14 CFR Part 61 that is growing more common. For Indiana-based pilots, this may mean considering operators in adjacent markets such as the Cincinnati, Columbus, or Chicago metro areas if local availability is limited.
For professional and corporate pilots, these endorsements carry operational relevance well beyond checkride preparation. Any pilot operating under Part 91 or 135 in piston twins — the Piper Seneca, Beechcraft Baron, or Cessna 310 class — must hold both endorsements before acting as pilot-in-command. Even pilots who have transitioned primarily to turbine equipment may find gaps in their logbooks if their initial training bypassed complex piston time. Chief pilots and Director of Operations roles in Part 135 certificate holders routinely scrutinize logbooks for these endorsements during hiring, and some insurance underwriters specifically inquire about their presence when quoting coverage for high-performance single-engine piston operations. Obtaining them proactively, rather than reactively when an assignment demands them, reflects the kind of credential management expected of professional aviators.
The broader trend shaping this discussion is the gradual disappearance of the complex aircraft category from practical training pipelines. The FAA's 2018 reauthorization eliminated the complex aircraft flight training requirement for the commercial certificate, replacing it with a technically advanced aircraft (TAA) alternative, which has further reduced the financial incentive for training operators to maintain aging retractable-gear piston fleets. As a result, the pool of instructors with recent complex aircraft currency is also contracting. Pilots in Indiana and across the Midwest who need these endorsements are well advised to identify qualified instructors and available aircraft early, confirm the aircraft's maintenance status and that the endorsing instructor holds appropriate currency, and document the training thoroughly in accordance with 61.31 to ensure the endorsement language in the logbook is unambiguous and compliant with FAA standards.
