I am indeed able to fly that VPT even without any FMS at all but still find it annoying and less than optimum use of equipment that the FMS commands a turn when no turn is required because the interaction between the database and the assumptions the FMS designers made clash with reality for offset approaches.

I do know about ARINC 424 leg types but some FMS manufacturers are less generous than others in giving away the abilities of their kit in those manuals usually handed to pilots...

As posted it's of course possible to disengage the AP before the MAPt to avoid the jerk at the MAPt, and 99,9% of cases one will be visual well before the MAPt given the weather Nice is blessed with.

It's more a matter of elegance than ability.
