The noise level of onboard recorded helicopter data is significantly high due to the rotor vibration loads. This report evaluates the possibility to sample flight test data without using anti-aliasing filters. After the A/D-conversion the data are filtered using an algorithm in a digital computer. These data are examined in comparison with anti-aliasing filtered data.
