212man, It is a statement!
The SOP was implemented because only part of the fleet was set up for the 'auto delete'!
I was talking about the situation where nav units (that were randomly set up or not set up for 'auto delete') were: (a) to be set up by the supplier on request of the operator or (b) to be modified by the operator nav-ops for the automatic deletion set up. Which, in my recollection, was/is not modifiable by the flight crew by means of the menu.
We probably have similar reasons for the auto delete. Amongst others: Without positively identifying the origins, some crew were activating waypoints/routes, inserted by a previous crew, that had utilised (with their reasoning!) some convenient, nice sounding, user-invented, questionable, random, identifiers. Previous crews sometimes inserting less precise coordinates, or even totally different coordinates for equally sounding identifiers.
Kind regards, learner . . .
