A classic 'children of the magenta line' approach to a circuit arrival. Sad days.
Hi RAT 5, I agree.
It is sad for those of us who flew before the invention of such aids like FMGCs and pictures on Nav Displays with actual wind and ground speed shown but it would be mad to dismiss them, because using such aids enhance our SA.
However I still believe it should be a basic skills requirement to be able to judge a visual circuit using the view out of the window, backed up with the scale markings on the NAV Rose Display if available and the wind vector information provided.
Making up spread sheets is only inviting other errors in the sheet and / or typos.
Always KISS.
