Dimensional Data and Principle Characteristics

The tables below show a summary of the dimensional and principle characteristics data that I have collected for US Single Engine WWII era aircraft, from the References listed on the Introduction page.  

Caveats

1. Please note all units are in pounds and that I am still in the process of filling in and confirming some of the information for these tables and graphs.
2. Because References 1, 2 and 3 sometimes provide data for the same aircraft, this data has been entered in separate, adjacent columns so that the data can be compared.
