18:16:36: Transition is too high at 12,000 ft. Transition should be given at 1000 feet above pattern altitude (1500ft AAL). For EDDB, an airport with a pattern altitude of 1654 feet, you’d want to give a transition that ensures 1000 feet of separation with aircraft at 1600/1700 ft. 3000 would be the best transition, because you need to round up the nearest 500. Rounding down would not meet the needed separation.
18:17:41: Unnecessary to ask me to say intentions
18:20:57: Unnecessary slowest practical speed command, and one that I am unable to comply with as I am at 12,000 feet and descending.
18:22:07: Slow response time to my 2nd inbound call, but good pattern entry.
18:22:28: No slowest practical!
18:23:47: Unnecessary “enter right base”. I already have a pattern entry (you told me to enter right downwind). Instead you should be clearing me.
Late clearance, as I was on base.
Thanks for the controlling!
One last thing - I don’t believe that you are meant to make a tracking thread unless you are wanting to become IFATC.
