What is the C42 used for?

The Ikarus C42 is the dominant UK National Private Pilot Licence (NPPL) and microlight training airframe at British Microlight Aircraft Association (BMAA) registered schools. It's also widely used at German LTF-UL microlight clubs and French ULM Class 3 operations. The type is purpose-built for the microlight / NPPL training scope; pilots seeking PPL CS-23 instruction transition to a Tecnam P2008 / P2010 or Cessna 152.

Can the C42 run on unleaded fuel?

Yes. The Rotax 912 ULS / iS Sport runs on unleaded EN228 mogas or 100LL avgas without modification, making the C42 naturally positioned for the unleaded-fuel transition where airport mogas infrastructure is available.

How much does the C42 cost to operate?

Hourly direct operating cost typically lands between £55 and £90 per hour at UK BMAA-registered schools, including fuel at 3.5 gph mogas plus Rotax 912 engine reserves and a fabric-inspection accrual. Wet rental rates at UK NPPL schools generally fall between £95 and £145 per hour. The C42 is significantly cheaper to operate than a PPL CS-23 trainer (Cessna 152 / 172) on a per-hour basis.

This entry is a fleet-research reference for flight school operators. Always consult the actual aircraft's POH (Pilot's Operating Handbook), the manufacturer's latest service documents, and the relevant FAA / EASA TCDS for any operational decision — flight planning, weight and balance, performance calculations, fuel loading, regulatory compliance, or maintenance scheduling. Numbers shown here are POH-typical for the family's representative variant under standard conditions and are not a substitute for type- and airframe-specific data.

Performance data
Reference data only — never use this entry for flight planning, weight and balance, performance calculations, fuel loading, or any operational decision. Numbers shown are POH-typical for the family's representative variant and standard conditions. Real-world numbers vary by airframe age, weight, density altitude, engine condition, and configuration. Always consult the actual aircraft's POH and the manufacturer's latest service documents.
Cost data
Cost ranges are illustrative reference figures for fleet planning. Actual acquisition, rental, and operating costs vary substantially by region, airframe age, engine and avionics generation, and local market conditions. Numbers should be validated against current quotes from local brokers, schools, and maintenance providers before any commercial decision.
Operator list
Operator lists capture schools and programmes we know to fly the type at scale. Lists are not exhaustive, may include operators that have changed fleets since publication, and should be treated as starting points for verification rather than current customer lists.

Why is the Ikarus C42 popular?

Structured popularity-driver evidence. Each axis below carries one factual statement; we don't grade, the facts speak.

Industry network effects

Dominant UK NPPL / microlight trainer at British Microlight Aircraft Association (BMAA) registered schools and at most UK-based microlight DTOs; very common in German LTF-UL clubs and growing in French ULM Class 3 operations.

Operating economics

Rotax 912 ULS burns roughly 3.5 gph at 95 kt cruise — comparable to the Tecnam P92 and Pipistrel Alpha Trainer on direct fuel cost, with a particularly strong operating cost position in UK NPPL / microlight training.

Fuel future-proofing

Rotax 912 ULS / iS Sport runs on unleaded EN228 mogas — naturally positioned for the unleaded-fuel transition without engine swap.

Production volume

Approximately 1,900 C42 airframes built since 1997 — one of the most-produced certified microlight trainers in Europe.

How flight schools track this aircraft in Aviatize

UK BMAA-registered microlight schools running C42 fleets typically configure them in Aviatize with NPPL-specific licence-validation rules and mogas fuel-surcharge models. Engine reserves track against the Rotax 912 ULS / iS Sport 2,000-hour TBO; fabric inspection cycles are tracked as separate maintenance items.
