It is great that I got so many replies on this subject, every individual experience counts and will be helpful to us.
The question "old school or new school?" is always an interested topic to discuss. Same is here with new and old technologies of guiding aircraft to the stand.
I would like to ask those who had experience with VDGS that we at LYBE are considering to repair or completely remove - Siemens VDOCKS (camera a/c recognition technology), please share some impressions here.
Still, I am more than grateful for any word on this topic. Thank you all.
