Does RDP require back tracking ?

I am asking this because I have read that if RDP doesn't require back tracking then it is a predictive parser(LL(1))!! 

predictive parser is a recursive descent parser that does not require backtracking. Predictive parsing is possible only for the class of LL(k) grammars 

https://en.wikipedia.org/wiki/Recursive_descent_parser  )

Does it mean that the RDP requires BT
