Thanks Slyguy - we're getting there... Slowly.
One point - try callng the Tower after 18.30. You will get a response from Denes Radio. No ATC currently from Denes after 18.30 local. Just A to G.
Currently the 'on airport' training requirements for a type rating are conducted at Norwich and sometimes Wattisham.
TCAS FAN - Both instrument approachs can be made outside the towers normal operating times. A note on the plate makes it clear however that contact with Radar must be maintained.
