Narrative:

Ramp pulled the power cord without asking or checking power light. Blanked captain mcdu temporarily and lost a couple of odd bits of data. We had to rechk all the programming; nearly causing a delay. I went down and talked to the ramp man. My exact words were; 'you have to ask us before you pull the power.' I then told him it sometimes dumps computers; but more importantly went on to explain how badly it could injure him under the wrong circumstances. I was a military aircraft mechanic and gave him an example of how an arc jumped 3 ft and injured my friend badly. I don't think it sunk in. He looked at me but didn't say a word. Because I didn't think he understood the ramifications of what could happen to him; I stopped and talked to a ramp manager and told him I thought his ground people could use some extra training on when and how to safely pull the power cord. I reiterated to him how you could get away with it 500 times and all of a sudden it could arc and kill. There can be no acceptable loss limits. This problem is not limited to ZZZ -- I see it through the system.

Title: AN A319 CAPT RPTS GND PWR CORD BEING PULLED WITHOUT ADVISING FLT CREW. DISCUSSED ACTION WITH RAMP PERSON AND EXPLAINED RESULTING ACFT PROBS AND POSSIBLE INJURY TO GND PERSONNEL.

Narrative: RAMP PULLED THE PWR CORD WITHOUT ASKING OR CHKING PWR LIGHT. BLANKED CAPT MCDU TEMPORARILY AND LOST A COUPLE OF ODD BITS OF DATA. WE HAD TO RECHK ALL THE PROGRAMMING; NEARLY CAUSING A DELAY. I WENT DOWN AND TALKED TO THE RAMP MAN. MY EXACT WORDS WERE; 'YOU HAVE TO ASK US BEFORE YOU PULL THE PWR.' I THEN TOLD HIM IT SOMETIMES DUMPS COMPUTERS; BUT MORE IMPORTANTLY WENT ON TO EXPLAIN HOW BADLY IT COULD INJURE HIM UNDER THE WRONG CIRCUMSTANCES. I WAS A MIL ACFT MECH AND GAVE HIM AN EXAMPLE OF HOW AN ARC JUMPED 3 FT AND INJURED MY FRIEND BADLY. I DON'T THINK IT SUNK IN. HE LOOKED AT ME BUT DIDN'T SAY A WORD. BECAUSE I DIDN'T THINK HE UNDERSTOOD THE RAMIFICATIONS OF WHAT COULD HAPPEN TO HIM; I STOPPED AND TALKED TO A RAMP MGR AND TOLD HIM I THOUGHT HIS GND PEOPLE COULD USE SOME EXTRA TRAINING ON WHEN AND HOW TO SAFELY PULL THE PWR CORD. I REITERATED TO HIM HOW YOU COULD GET AWAY WITH IT 500 TIMES AND ALL OF A SUDDEN IT COULD ARC AND KILL. THERE CAN BE NO ACCEPTABLE LOSS LIMITS. THIS PROB IS NOT LIMITED TO ZZZ -- I SEE IT THROUGH THE SYS.
