Manchester Runway 23 Right?!

Sat Jun 09, 2007 3:12 am

To my amazement today when listening to the air traffic, manchester's runways have changed numbers ;-O , when did this happen? and i thought the MAG was 236 degrees last time I checked so even if it went to 235 it would be 24. Anyone able to help me.

Magentic variation change, it alters slightly every year, but there comes a time every few years when they actually need to re-designate the runways to compensate for the actual magnetic heading. Something along those lines.  Smile

The designation changed on Tuesday I believe  Smile

Does this affect any systems? Do aircraft FMS/FMC's need to be updated?

I'm gonna guess yes, as ILS information usually incudes the course heading, so you can "home in" on it, I believe..

Maybe one of our resident pilots can explain in more detail??  Smile

FMCs are updated on a 28-day cycle, so the change will be incorporated into the next change (in fact, the date was probably selected in order to coincide with a change). The actual heading of the runway will only have changed by one degree, though the ILS courses will need to be updated as well, as well as the runway designators in the FMC database.

In Non-aviation? I suggest moving it to Tech/Ops.  Smile
