We evaluate the nuclear modification factor (
) of average D mesons at center of mass energies 
= 2.76 TeV and 5.02 TeV in two centrality classes incorporating radiative energy loss in an anisotropic quark–gluon plasma (aQGP). A simple (1+1)d hydrodynamic model is used to describe the space-time evolution of the aQGP. We compare our results with the ALICE and CMS measurements and it is found that the data are consistent if the isotropization time, 
, is between 2 and 4 fm/c. We also plot the ratio of at = 5.02 TeV to 2.76 TeV and find it to be consistent with the model prediction existing in the literature.
