As planned I went in for the Class 4 Medical examination.
Everything was OK but I did get an excluded from night flying, since I once again failed the Ishihara test.
They also take an ECG (electrocardiogram) and some other examinations.
Since at the moment Class 4 (for ULM) and Class 2 (for PPL and LAPL) are the same examination, I received both.
If I choose to do PPL I'm already medically checked. Or if the EASA (European Aviation Safety Agency) suddenly decides to regulate ULM they will likely regulate it under LAPL (Light Aircraft Pilot License), which also requires Class 2.
Not much more to say about this, all is good, now I have to request my practice license from the government.
