The Repositioning of Earth’s Magnetic Field Requires Changes to the Runways at Reno’s Airport

NEVADA – The magnetic field of the Earth moved magnetic north. It’s always in motion. Magnetic north has shifted enough over the years that manual compasses must be recalibrated, printed maps may be out of current, and airport runways may be renamed.

“The earth changes, and as that molten core shifts, you can shift a little bit for pilot safety, because it’s always all about safety,” explained Brian Kulpin of the Reno-Tahoe Airport Authority.

Runway 1634 right has been renumbered 1735 right. The runway number 16 was repainted to 16 R a few weeks ago.

The numerals not only identify runways, but they also indicate pilots how far the runway is from magnetic north.

According to pilot Jonathan Hartness, electronic cockpits are automatically updated.

“It’s a really simple change, nearly seamless for those with glass cockpits and a lot of avionics and electronics,” he explained.

Airport runways are being replaced around the country. Hartness stated that he witnessed Florida renovate their runways a few weeks ago.

Reno’s airport serves 4.3 million passengers each year. From the airport, pilots fly 150 flights every day.

“They’re all using these runways, so you have to have the correct designation for safety,” Kulpin explained. “It helps all those planes line up and be and be managed by the air traffic control tower.”

Most people will be unaware of the changes, which are necessary to keep people safe.
