To all interested: Effective 5/17/01 Cleveland will replace runway numbers 5L/R and 23L/R with 6 L and R and 24L and R. It's gonna take people a while to get used to this one!

They don't need to be 10 degrees out to be changed. I don't have charts in front of me, but eg. if direction was 053 before, and now 056, then it would justify the designation change.

Pretty sure it has to do with Coriolis Force. The magnetic headings of the Earth are always increasing in the northern hemisphere because the rotation forces them in a clockwise direction. Anyone back me up? Or school me to some new info?

Years ago, when DFW first opened, what is now 18L used to be 17R. When they built the additional runways, the "right side" (west side) runways were renumbered 18/36 and the east side runways kept the 17/35 designation

This is an interesting topic and can be very technical. Magnetic progression/regression takes place around the globe and it isn't always in the clockwork direction in the northern hemisphere (the Coriolis Effect does manifest itself with water going down the plughole and low pressure systems though).
To prove the point, whilst Cleveland is progressing from 05 and 23 to 06 and 24, in the last 50 years Heathrow has regressed from 11 and 29 through 10 and 28 to 09 and 27.
Manchester, less than 200 air miles away hasn't changed from 06 and 24 since 1938.
Magnetic variation is, I understand, predictable and is noted on aviation charts.
The "numbers" used in giving runway headings are to the nearest 10, and the full correct heading is shown on all charts which are updated , often up to 6 times per annum

N766UA, where do you get this info? I'm not saying that you are lying, but the approach charts that are valid until 7-12-01 designate these rwys. as 5-23. So, now if this proves true, after expansion, the runways will be:6W-24W, 6C-24C, and 6R-24R since the COEx runway was to be the only runway designated 6/24.

KCLE: My info:
First: I have the FAA Notams
Second: I hear it used on the scanner
Third: My dad is an ATC at Cleveland
Fourth: I know 2 CO pilots who I emailed about it.
Airbus: It does screw them up. They say "Inbound for five...uhh...six right... oops" all the time.

I had a chance to go to CLE today (between the raindrops! LOL!) and you are absoultly right. I live too far to hear ATC, so I was in speculation, but I even saw the new "24"s on the runways through my binoculars. The pilots have gotten used to the #s already. Will this mean that 10-28 will become 11-29? Also, when were the new numbers painted? I have a feeling it was 5/18, because after the rain went by, (don't you all just love Cleveland's weather !?) the skys were clear, but all of the planes kept landing on 28 that evening. Did they paint the numbers then?

I forget the exact date. Check jeppessen.com They have the notams. 5/23 is the only one changed.
