We have incorporated all airspace changes into our Germany chart due for release this Thursday, just as we do every 28 days.

The new transponder codes are not currently part of the AIP, so it is likely that our chart on Thursday will not include the codes. Moreover, the software itself isn't currently designed to recognise transponder codes attached to TMZs as these are the first in Europe. We are in discussions wit‌‌h DFS about how best to incorporate the codes, as they are currently part of the proprietary Eisenschmidt charts for Germany only. I'm sure it won't be long before a good resolution is found though; we may even be working with DFS at Aero Friedrichshafen.

We will deal with that AIRAC change sometime between the 2nd March and its effective date, in that case.

We have had Listening Squawks in the UK for some time. They are handled like FIS frequencies in SkyDemon.

I do not know what date you are expecting to see these appear in Germany, but we have already created the charts valid 2nd March and no changes indicating the introduction of listening squawks have been observed. Perhaps they are coming later in the month.

The new season begins with a change of procedures in TMZ (Transponder Mandandory Zone) areas. According to the previous regulation, a transponder had to be carried along and coded on code 7000.

A new addition is the radio readiness on radio. According to information from the Federal Committee on Lower Airspace (BAUL) this radio capability is to be signaled with a corresponding Squawk code. These will be published in the DFS ICAO aeronautical charts available from March. The expansions of the individual TMZs remain unchanged.

In practice, this does not mean the release of the corresponding transponder code and monitoring on the published "Listening Squawk" frequency. It is hoped that this will improve the safety of the air because, in case of doubt, a pilot can quickly make contact with the pilot. There were also problems in the past that the Squawk codes were still "tagged" for several days, because after logging out of FIS no code 7000 was saved and / or the following pilots did not check your transponders.

How SD will handle these Thematik? ..as like the FIS Frequency in the terrain-data?
