Summary:

Flight tests are now in progress at the Langley Memorial Aeronautical Laboratory on a Sperry Messenger airplane to determine its lift and drag characteristics when rigged with different sets of wings. At the same time wind tunnel tests are being made on a one-tenth scale model so that comparisons to determine the scale effect will be possible. The ultimate aim of course is accurate performance prediction from wind tunnel tests. The flight tests are accomplished by the so-called "glide method" and since glides have been used for some time to obtain the lift and drag of an airplane, nothing new as to the basic method can be presented. However, some new facts have been brought out by recent experience which seem to be of enough importance and general interest to justify this note
