Frequently Asked Questions

  • Are the PowerFlow™ ground power units capable of starting my aircraft?
    No, none of the units will provide enough amperage to start the engine. A battery powered jump starter would be more suitable for this type of function.

  • Do the PowerFlow™ ground power units need to be plugged in to be used?
    Yes, the GPU converts AC current into DC current for the aircraft so it will need to be plugged into an AC source to be used.

  • Can I get a longer cable to connect to my aircraft?
    We limit our aircraft cable to around 7' in length. This is because voltage loss occurs with DC current, and this loss increases with the length of the cable. If you need longer cables for your application we recommend that you use an extension cord of whatever length you need on the AC input side of the unit. 

  • Are your products compatible with 12V/14V aircraft?
    Our products are designed for 24/28V aircraft only.

  • Will the PowerFlow™ line of ground power units charge the aircraft's battery?
    Yes, the power supply will "top off" the battery while it is being used. However, it is not recommended to leave the power supply connected to the aircraft unattended for extended periods of time. 

  • The avionics are flickering and/or the voltage on the aircraft voltmeter is not holding while using the PowerFlow™ unit, what is going on?
    This occurs when the power supply is overloaded. In those cases the unit will shut down and restart until the overload condition is resolved. This may be because the unit is not compatible with your aircraft, or that there are simply too many high load systems powered on at the same time. 

  • Why are wall plugs not included with the PowerFlow-100™, PowerFlow-200™, and PowerFlow-300™?
    Due to the wide variety of plug configurations in hangars around the US and the world it is difficult to supply the correct plug for each individual wall socket. This is why these GPU models are delivered with one end of the cable open and ready for a suitable plug to be sourced and installed by the customer in the field.
