since march 31 two of zurichs tma's have now new hours of operation and they have new frequencies assigned for crossig requests.
the tma's in question are tma 14 and 15 as shown on the image below. in order to request crossing or activity information, one now needs to contact Zurich Terminal 127.75 instead of Zurich Information 124.7.

please update this information in your charts on the next update.


kind regards

I am trying to find an official source for what you are saying. Looking at ENR 2.1 for Zurich TMA parts 14 and 15 it is by no means clear that there is a separate frequency required to gain entry to those pieces of airspace. All I can see is some notes saying that a listening watch is mandatory on that frequency. Is that what you're referring to?

Hi Tim, thanks for looking into this. how about the swiss icao chart, it can be found here:
https://s.geo.admin.ch/69479772d0

if you look at tma 14 and 15, you can see the new frequency noted on the chart.

The Swiss ICAO chart is the official source of aeronautical information; the AIP is. The authors of that chart may have decided that the mandatory listening watch on that frequency is a good reason to display it on their chart; I would agree with that decision! But we still have to decide ourselves whether the frequency to gain access to that airspace (as encoded in our own chart data) should be changed to that one, and unfortunately the AIP doesn't make it clear.

I will ask my colleague to liaise with the Swiss authorities for their opinion.

This point seems to be fixed. Unfortunately, in the SkyDemon chart for those airspaces, the frequency (of Zurich Terminal) is wrong. Correct 127.750 instead of 127.150.


Operationally speaking:
I think to gain access to those airspaces at arrival or transit you have to contact Zurich INFO. Zurich INFO will maybe redirect you to Zurich Delta or Zurich Terminal. At departure, you are in contact with Tower, which should give you the frequency to contact. In any case, I do not think you will obtain such clearance in VFR.
