Phoenix,it becomes automatic after awhile-4 items with the first radar vector heading:Select heading and 'heading pull'
select alt to 'idle open' to release 'verticl speed' from last value(2500)..This allows the 'speed select'to go to the required speed(if still in 'vertical speed'(2500) the magic won't slow the speed as it satisfies the vertical value still in place)
activate the 'approach mode' to slow to G/Dot when released from 'speed select',thence clean up the Flt/pln to give accurate info to landing!!
cheers...
