  We report on an easy-to-evaluate expression for the prediction of the
bend-loss for a large mode area photonic crystal fiber (PCF) with a triangular
air-hole lattice. The expression is based on a recently proposed formulation of
the V-parameter for a PCF and contains no free parameters. The validity of the
expression is verified experimentally for varying fiber parameters as well as
bend radius. The typical deviation between the position of the measured and the
predicted bend loss edge is within measurement uncertainty.
