Aircraft separation standards for manned aircraft are influenced by Required Navigation Performance (RNP) specifications under the Performance Based Navigation concept. Unmanned aircraft operating in a Unmanned Traffic Management (UTM) environment will require separation and thus similar standards need to be derived. This work expands on UTM flight trials conducted in Singapore to characterise the navigation performance of common multi-rotor platforms. Real flight test results enable derivation of the navigation error distributions which are subsequently used to suggest suitable RNP values for the platforms. Additionally, it is found that navigation capability of UAS in close proximity to buildings cannot yet be meaningfully evaluated.
