[NSRCA-discussion] Arming Device for electric airplanes

Wed Sep 26 11:44:09 AKDT 2018

So I work in a field that is heavily involved with folks who try and take human factors out of it, even when a soldier is completely in the wrong they try and put a process in place to fix this. What I’ve found is that you can try and limit as many factors as possible but it still comes down to knowing the equipment and how it works. Plain and simple, I have had numerous different folks grab my airplane and never once has it gone full throttle. It’s because I treat it like a loaded gun. It can and will bite if you allow it. So we add an arming plug to prevent this, what do you do to stop a glow model to start at full throttle? There isn’t anything they can do but know there equipment.

Many canopies can be fussy about how they go on and off and, at a contest where we try to keep things moving quickly, especially when one plane has just landed and another is on approach it’s quick and easy for the caller to disarm the plane and carry it into the pits if there is an external device.  Without that, and in the hurry-up scenarios it is real easy for an armed plane to get carried into the pits.

They AREN’T a problem because they fly so much and have a regular caller who knows the routine and quickly disarms the plane, etc. but they need to set an example for the rest who DON’T have those advantages.  I get the “point of failure” concerns, and agree that things like the deans arming plug approach, etc. can introduce those. But an anti-spark external arming bullet, IMHO *reduces* points of failure by ensuring you get no carbon buildup on any battery/ESC connections.

It is basic safety that has been proved in the industry.  Any power electric circuit has to have an external visible disconnect.  It is just the basic "Show me rule"   We just want to make sure that the gun cannot fire.  Of courser there are always exceptions and accidents happen.  However, the external arming switch will reduce the chances of accidents for sure.

>> The method of disarming the plane is only as good as the pilot (external or internal).  It is for the pilot to enforce the safety of his plane, otherwise you need a watchdog at every flight line to really see the action take place.  In the later many of us take for granted and expect the pilot to do his job.  Sometimes we observe the disarming and sometimes we don't.  Perhaps this is where the biggest improvement in safety could take place.

>> This last weekend's pattern contest, I noticed a pilot take his plane out of the car, put it all together, then start to put flight pack in, with the arming plug still installed!?  Point is safety errors will happen regardless.  We are the drivers of the planes, thus we need to be the 100% responsible party of course.  I think the biggest improvement we can immediately apply is to individually watch what our buddies are doing, and just be the extra set of eyes and caution.  Lets help each other not make these critical errors.

>> This is real experience.  About 3-4 years ago I was getting ready to fly with another friend.  Both of our planes were already in the pits and we just were talking before starting the day.  A pilot came with an electric plane and parked between us.  He left it there and decided that he needs to go and get something.  About a minute later his plane came to live suddenly and took us from the pits.  It starting to do an small loop and was coming directly toward us.  It was so fast that my friend said "take cover". We were lucky that the plane crashed in front of us and there were no more pilots flying or around.  It was so fast that I didn't have time to move an inch and could have hit us easily.  The plane didn't have an arming switch outside so there was no way for us to know if was armed.  The owner came and we never were able to figure out what really happened.

>> I think makes sense to put together a formal request that will require external disconnect outside the electric powered planes.  It is easy to justify since is already a requirement of the National Electrical Code and OSHA.  Anyone out there wants to put together a draft.  I will help to signed since I am a CD.

>> Rule says you must disarm the plane before bringing into the pits, does not say how.  That can mean take off canopy and unplug.  I’ve moved to using a Jeti anti-spark bullet in-line on the red side of the battery-esc connection with the bullet routed to the outside of the plane.  Quick, simple, foolproof.  Anti-spark prevents carbon buildup on the bullets.
