The angular resolution of events simultaneously observed by the fluorescence and surface detectors is derived using Corsika showers and a hybrid detector simulation. Its dependence on energy and geometry parameters is discussed.The study of angular resolution has been extended to multi-eye events which can be reconstructed also in stereo mode. Using the combination of the reconstructed axes, the angular resolution derived from data is compared to simulations. Events with energy larger than 1018.5 eV are reconstructed with the surface detector and compared to hybrid.
