The software runs stable, it has an easy to use interface which can be operated with mobile devices as well! It's very important that there are no problems in connection of the device or server side when using this airmast system at airports - not only during flights but also before take-off/landing etc., so I would like more details about these aspects from you guys!! We have implemented our own ATC (Air Traffic Control) tower application including voice communications between controllers & aircraft pilots via radio frequencies instead of VHF omnidirectional range channels used by conventional radios currently available today. This makes working much easier especially since we operate several different towers simultaneously while ensuring safety without any interference due to other users nearby. ! Our implementation was done entirely within 2 weeks after accepting your proposal because both sides were satisfied! Also all staff involved got familiarized quickly enough thanks again!! In addition i am happy how fast support could react once.
