Hi Alan,
Apologies for the late reply, I've been away from my computer for a week. On VH-EPV, I was at Lanseria with my RB when it arrived and departed and tied it up on both. It was using 'WAC' as callsign.
As for ZS-CTI, I've just run an update, (as I do most weeks) but it doesn't show in my database. Strange. I have 481280 aircraft in the database. It that correct?
You asked about ZT-WVR. I guess it's a light aircraft? I don't normally do light fields, but if I do come across it I will let you know.
Regards
Steve
