Shifting Magnetic Poles

From Steve Stewart

In October, Transport Canada put a proposal to the 13th ICAO Air Navigation Conference on the topic, which was well supported.

The change is something we should expect in due course. In the meantime, it seems our use of magnetic north has just become less accurate again, and those runways might not be exactly where you think they should be.

It gives additional focus to the need to switch navigation away from magnetic north to True North.

NavCan did testing last year in Nova Scotia which confirmed the reasonableness of the change and that it can be achieved successfully.

Here is an interesting article related to the increasingly shifting Magnetic North Pole:

Shifting North Magnetic Pole Forces Unprecedented Navigation Fix

January 11, 2019 by Reuters

By Alister Doyle OSLO, Jan 11 (Reuters) – Rapid shifts in the Earth’s north magnetic pole are forcing researchers to make an unprecedented early update to a model that helps navigation by ships, planes and submarines in the Arctic, scientists said.

Compass needles point towards the north magnetic pole, a point which has crept unpredictably from the coast of northern Canada a century ago to the middle of the Arctic Ocean, moving towards Russia.

“It’s moving at about 50 km (30 miles) a year. It didn’t move much between 1900 and 1980 but it’s really accelerated in the past 40 years,” Ciaran Beggan, of the British Geological Survey in Edinburgh, told Reuters on Friday.

A five-year update of a World Magnetic Model was due in 2020 but the U.S. military requested an unprecedented early review, he said. The BGS runs the model with the U.S. National Oceanic and Atmospheric Administration.

Beggan said the moving pole affected navigation, mainly in the Arctic Ocean north of Canada. NATO and the U.S. and British militaries are among those using the magnetic model, as well as civilian navigation.

The wandering pole is driven by unpredictable changes in liquid iron deep inside the Earth. An update will be released on January 30, the journal Nature said, delayed from January 15 because of the U.S. government shutdown.

“The fact that the pole is going fast makes this region more prone to large errors,” Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and NOAA’s National Centers for Environmental Information, told Nature.

Beggan said the recent shifts in the north magnetic pole would be unnoticed by most people outside the Arctic, for instance using smartphones in New York, Beijing or London.

Navigation systems in cars or phones rely on radio waves from satellites high above the Earth to pinpoint their position on the ground. “It doesn’t really affect mid or low latitudes,” Beggan said.

“It wouldn’t really affect anyone driving a car.”

Many smartphones have inbuilt compasses to help to orientate maps or games such as Pokemon Go. In most places, however, the compass would be pointing only fractionally wrong, within errors allowed in the five-year models, Beggan said.

John Sessions’s recovery from accident at YXX

As many of us know, John Sessions had an accident at the Abbotsford Airport after the Airshow on Saturday night. John was taking a group up for a flight in the Heritage Flight Foundation’s newly restored DeHavilland Rapide when it crashed shortly after takeoff.

Below is an article that talks about John’s road to recovery and path back into the cockpit

President’s Column – January 2019

Happy New Year, fellow Abbotsford flying club members!  The New Year means different things to different people. For most people, it means resolutions with the goal of becoming a better person.  On my daily dog walks, evidence of this appears in the form of a flock of joggers who I have noticed running around the neighbourhood.

In the past I used to make a resolution every year to fly more, to eat less, exercise more and work at being a better husband and father.  By the time July rolls around, I would have made a few minor changes but typically I’ve settled into a groove and the changes aren’t as noticeable.  For the past couple of years, I’ve just started setting out regular times to reflect on how things are going and work out how to make things better.  The constant approach seems to work better for me and gets me to ensure that I’m balancing my duties and the things I value based on the situation at hand – rather than one I may have imagined back in January.

So what self-improvements does your situation allow for?  Are you going to volunteer more?  Are you going to spend more time with your family?  Are you going to try to make new friends?  The holidays provide a time for reflection, but are you prepared to set up times during the upcoming year to reflect, take stock and recalibrate?

With respect to the club as a whole, we have a lot to look forward to this coming year!  We have our special events like Wings and Wheels, First Flights for Kids, the Airshow and a number of weekly TGIFs (some of which follow a theme).  We have a year of flying to look forward to – weekend flyouts, events at other clubs, air races and our new aircraft to fly.  There are also a number of new members who I’m sure it will be good to get to know over the coming year.

I wish you all the best in 2019 – may you be blessed with blue skies and fair winds for all your flights.

Yours truly,
George

AFC New Year’s Party

The  New Year’s dinner party that was organised by Clark Closkey was an overwhelming success.

The table centrepieces were made by Jeanette Campbell. We had real table cloths, courtesy of Leanne and Murray Webb.

44 steaks were served with salads, onions and more than 20 pounds of Jill Greystone’s mushrooms. There was also a great selection of desserts to choose from.

The dress code turned out to be an exercise in elegance. It looked more like a captain’s dinner on a cruise ship instead of a club function. Well done ladies and gentlemen.

Adrian did a head count at 1030 pm and out of 44 people, 42 were still there. It appeared that everyone had doubled up on their Geritol.

Happy new year!

Adrian, Ken and Chris

Wind storm at YXX

As most of you know, we had a pretty heavy duty wind storm move through the Lower Mainland on Thursday the 20th of November. There was not as much damage as there could have been considering the winds at times were gusting more than 60kt!

The most serious damage that was reported was on the hangars in the compound that the AFC manages. Manned security was put in place almost immediately and the damaged doors were repaired quite quickly. Good to know that the roofs are in good shape!
