When the battery in a car is unable to start the engine, you can connect a set of jumper cables to get the engine started.  Many FBO’s aren’t real keen on “jumper cables”. Too much potential for connecting them wrong and doing major damage to the aircraft electrical system. Most 28 volt aircraft have ground power connectors. It allows you to connect the single cable to the aircraft with no chance of connecting things wrong.

Albert gave me a Ground Power Receptacle a while back so now all I have to do is figure out where to put it. I was going to put it under the battery tray but once I looked at the size of the plug I realized that wasn’t going to work.

So I put it in the nose. This way, it’s easy to get to on the ground when the nose gear doors are open. People that use the factory nose landing light can’t do this because the landing light is in the way. Yet another advantage of landing lights in the canard.
