"...Using or even leaving a live cell phone near autopilots, GPS, instruments, fluxgate compass’s or computers etc can cause major inaccuracies and interference. "
The story is the first one on the page, but you have to scroll down a bit to get to it. Definitely confirms something I thought had happened a couple of times, but couldn't seem to replicate exactly.
Okay, okay it's Thanksgiving Day, but if you are shooed out of the kitchen, then....<grin>

Sure... especially when you consider the number 1 cell phone race tactic... speed dialing the opposing helmsman exactly one second before executing a major snookering maneuver.Didereaux wrote:"...Using or even leaving a live cell phone near autopilots, GPS, instruments, fluxgate compass’s or computers etc can cause major inaccuracies and interference.

HAHA!!! Quite devious indeed. Good show!
In the bleak midwinter Frosty wind made moan, Earth stood hard as iron, Water like a stone; Snow had fallen, snow on snow, Snow on snow, In the bleak midwinter, Long ago.

cell phone
I very recently had a boat surveyed. She was on the hard. The compass stood motionless. The surveyor took his cell phone from his pocket and from 1 foot away passed the phone in front of the compass and was able to move it 180 degrees. Checked off as operational.

That explains why we're asked to turn them off during a flight.

COMPASS DEFLECTION
Hi all,
Here is a little story for a quiet weekend that has a different slant on what can happen with compass deflection.
After the war was over, sometime during the late 1940s and 50s, right before the advent of fibreglass hulls made popular by Hatteras and then MFG and others, there was a class of power boats that was becoming popular with the evergrowing group of new boaters who were returning from the wars.
These 21', 24', and 26' wooden lapstraked craft were better known as Sea Skiffs. The more well known makers were Morgan, Luhrs and Uhlrichson. A very dear, departed owner of a Morgan skiff told me this story. But first, let me mention that this person wasn't a newbie to the maritime scene by any means. He served in the Merchant Marine service during the war and had captains papers, which he kept renewing as often as required.
One fine, early morning, being fully provisioned and fueled, he set off from his slip on the south shore of Long Island, NY and headed out into the Atlantic for a day of deep sea fishing, well into the shipping lanes, out of sight of land.
As the day wore on, my friend decided that it was time to return to port and proceeded to do so. Using his compass, he retraced his route for port but noticed that things weren't working out as planned.
Could the compass be off? Hmmm, land should start to appear by now. Something wasn't right. Fuel was a concern by now. Radios were a rare commodity back then. The wizened old sea dog then relied on his experience and wits.
Since it was a cloudy, drizzle filled day, the sun's position didn't help him at all. He didnt do anything until dusk. As the daylight shortened, he got a relative idea of direction by noting the dark sky in the east and the lighter sky which would be west. Using this primitive info, he checked it with the compass which was totally out of whack.
As the night darkened, using dead reckoning, my friend peered into the direction he figured would help him. Aha, there it was, the faint glow of the Fire Island Light bouncing off the thick cloud cover. My friend, after determining that he was way off course, was now returning home.
You might never guess what went wrong. The compass later proved to be in A1 shape. Years ago there was no such thing as pop top soda or beer cans. You had to punch a hole in the cans with a pointed steel tool. For convenience' sake, my friend would place the "church key" on the flat surface on which the compass was mounted in order to keep it handy. Unknowingly, the compass was deflected by the close proximity of the steel opener.
Is there a moral to this story? I don't know, what do you think?
Have a nice weekend.
