The study was undertaken to find an easy-to-use take-off distance prediction method and to evaluate its applicability to STOL aircraft. For the purposes of the study STOL aircraft were defined as those requiring a take-off ground roll of less than 1000 ft. Two existing take-off ground roll estimate methods were evaluated by comparing predicted values with available data for several STOL aircraft. The resulting accuracies were respectively within 9% and 11% error. It was found that one of these methods could be further simplified and yet still yield acceptable results. That is, excluding two predictions this simplified method yielded an accuracy within 13% error. In addition, some correlation was found to exist between short take-off ground roll and total distance over a 50 ft obstacle. As a result an expression was derived relating the two. (Author)
