@martyn I just woke up (in New Zealand) and that email was the 1st thing I saw on the computer. I'm gobsmacked, that was so fast ! Adding the TACAN to VOR frequency conversions to the checklist was a relatively simple addition but this ... you must have had this lined up already, this can't possibly be a response to something I said 24 hours ago ! (but I'm going to claim it is anyway 😄 )
Thank you !
