Any DTV traffic above Woodland is going to be in direct conflict with NCL app and dep 99% of the time, so (even if DTV's radar extends that way) there's already plenty of confusing radar returns. Are you suggesting that Peel should request payment from NCL ?
There is absolutely nothing to link Peel/DTV to this application, so why try to do so, (whilst demonstrating poor geographical and airway knowledge) ?
