Kind regards, learner . . .
It is also possible with the FMS fitted to the S-92 (UNS-1) to automatically delete all User waypoints/routes on power down. That was how I had ours set up in my previous role, so that only Company waypoints and Routes (plus, the Jepp NAV Database) remained - neither of which are modifiable. This meant that the User database remained solely for tactical use during a specific flight.
