With AIRAC 2309 effective from 7.09.2023 a few changes in EPWW FIR, including primarily new SID/STAR procedures at EPKK/EPKT airports along with TMA boundaries change. Changes will be published in AURORA. In addition, to facilitate those who do not always need the latest AIRAC in the sim, the old procedures will be maintained for a while and named (OLD). Cheers
