The Full-Scale Tunnel (abbreviated FST, also known as the 30-by 60-Foot Tunnel) was a wind tunnel at NASA's Langley Research Center. It was a National Historic Landmark . In 1929, National Advisory Committee for Aeronautics began construction of the world's first full-scale wind tunnel.

Scale effects in wind tunnel modelling are studied by comparing the results from models with various scales with the atmospheric boundary layer. It is found that the scale ratio of roughness height should be the same as the scale ratio of boundary layer thickness.

What wind speeds to use in a scaled 1: 64 wind tunnel ...

The wind tunnel model might not have all the details (such as antennas and gaps etc) as the full scale aircraft and this will typically have an impact on the estimated drag of the aircraft. The aeroelastic effects are different when comparing the wind tunnel model, the full scale aircraft and the CFD model.
