ATC has been giving me clearances with T routes quite a bit lately and, of course, this will become even more prevalent as more VOR get decommissioned. Unfortunately, there is no viable workaround in iFly GPS. For those who aren't familiar with them, a T route is a GPS only route that works similar to a Victor airway -- except there is no minimum altitude to receive a ground-based nav signal. Min altitudes are typically the MOCA.
