Since you already have an RTR you don't need an FRTOL, all you need is SPL to fly solo in India. (RTR supersedes FRTOL)
Are you sure about that? My understanding was that RTR is sort of like a NOC from Ministry of Telecom telling DGCA that we are capable of operating an aircraft radio. And its the FRTOL that actually allows us to operate an aircraft radio.
The whole point in having an RTR which is different from FRTOL is unfathomable to me but if RTR supersedes FRTOL, what is the point in paying Rs5000 for an FRTOL?
