Your "protection" is to:
a. Have a proper knowledge of the service you have asked for and got.
b. Avoid areas where you may be in conflict (duty of care to one's self) if reasonable.
c. Re read point a. and get a higher level of service if point b can't be applied.
If you choose to fly in places / hts where you have no help - you are one yer own and liable to see "suprise" traffic.
