Fuel and control
Confirm the fuel.
Confirm the calibration.
The published HFD range uses electronically controlled direct injection, spark ignition and air cooling. Fuel approval and calibration belong to a specific engine configuration.
Ask for the supported fuel specification, calibration revision, starting procedure and operating limits for your selected engine. Do not assume that a change of fuel is covered by an existing configuration.
What to define for integration
- Mechanical: installation space, mounting loads, propeller or driven-load interface and accessory clearances.
- Thermal: cooling airflow and representative ground and operating conditions.
- Fuel: the exact fuel grade and the required fuel-system arrangement.
- Electrical: starting method, available supply and generator requirements.
- Control: throttle command, monitoring requirements and confirmed interface documentation.
Published ratings do not replace an installation-specific performance assessment. Request the current technical package before selecting a final configuration.
