The EPU is a hydrazine-powered, self-contained unit that can provide emergency hydraulic and electrical power for about 10 minutes. If the generator is OFF and the engine RPM is above 80%, it will simply derive power from the engine and the light will start to blink. However, as soon as RPM drops below 80%, the EPU will start to burn EPU fuel and the light will be constantly lit.

- Do not exceed 550km/h calibrated airspeed with landing gear in DOWN position, otherwise the landing gear might get damaged!
- Do not exceed 400km/h true airspeed on the runway, otherwise the landing gear might get damaged!
- Do not apply the wheel brakes if the true airspeed exceeds 300km/h, otherwise the landing gear might get damaged!
- Do not exceed 15° pitch on the runway, otherwise you will scrape the nozzle on the runway and the plane will catch fire!
