Beags,
As I said earlier, we have made significant progress with the new version, some of which was pushing the contractual boundaries. Whilst I agree that the ADS method of not engaging with the operator was flawed, unfortunately they were trying to protect against requirement creep. Unfortunately that led to a system design that is sub optimal and required a lot of work to get anywhere close to meeting the requirements of the end user (not always the same as the contractual requirements!) We can definitely move the bracket set positions now by defining a start point using the distance from a geographic waypoint, a bit like we did with AARWIN. Again, not perfect but usable and something we can work on with future versions.
