Hy,
We had some local writen procedures established between our company and the airport authorities. (since we had a few TCAS TA issues...)
It was like : -XPDR code 7123
-ATC had to be contacted
- If possible, do the test at night, or we had to request a slot
for daytime.
-We had to tell them what altitudes we will use and for how long
(In our case they had to contact Zurich radar if we went above
FL100)
- A/C in hangar and doors closed
Regards,
og
