So I choose e.g. Runway 08 and STAR ABC - each are now marked with <SEL>

 

I seem to be able to delete these options with ERASE - or just by going back to the FMC and choosing ARR/DEP again.

 

But eventually I seem to "lock" my choices - ERASE/DELETE don't work - what am I doing wrong? How to go back to square one, so to speak?

Hi Paul,

 

I assume you are being 'locked' out after you have executed the entry you put in on the DEP/ARR page.

 

By re-cycling the DEP/ARR page, you should go from having only your selected choice displayed, to all of the available options displayed.

 

It should go from this;

 

 

to this after recycling DEP/ARR button;
