Thanks for the replies and especially the airbus video which has cleared a lot up for me.
I fly for a pretty big A320 outfit and was surprised there’s no mention of it but guess it hasn’t been optioned. The focus seems very much on RNAV. Certainly having temperature corrections would be great at the time of cold temperatures. Can see a big benefit for doing a back course approach although can’t think of any in Europe unless anyone knows of one ( I know a small section can be used for 08 Innsbruck).
Thanks for your help.
