I am living not too far away from Vienna airport (VIE / LOWW) in Austria. This airport observes a night curfew between 23:00 and 6:00 local time every night. However to my knowledge, the curfew does not apply for emergency landings. I wonder what kind of preparations the airport (or any airport with a similar regime for that matter) makes to accept diverting aircraft due to technical or medical emergencies.
- Is the control tower in operation 24/24, or would someone from Vienna center ATC take over?
Is the fire brigade on duty? (I would assume they are, since parked aircraft might develop a problem, or something might occur in the airport buildings etc.)
What if it's snowing? Will the snow removal teams keep at least one runway clean throughout the night?
