02 / SELECTION INPUTS
What defines engine selection
A single power, displacement or thrust value is insufficient to confirm compatibility.
- Aircraft configuration
- Maximum takeoff weight
- Mission profile
- Operating altitude
- Target endurance
- Installation envelope
- Cooling airflow and exhaust routing
- Propeller constraints
- Fuel and ignition supply
- Ground and flight validation
