Abstract
The USFS has collected flight data on Beechcraft King Airs which are being used to support firefighting operations. The data from 3094 flights is presented in this paper. The flights are separated into six specific phases, some of which are unique for firefighting missions. The two-second rule is used to separate vertical loads into those due to gusts and those from maneuvering the aircraft. The incremental vertical gust loads are then used to find derived gust velocities. The derived gust velocities are shown in frequency of occurrence charts for the individual phases, as well as for the entire flight. The derived gust velocities are shown in AGL altitude bands, to show the results as height above the ground increases.
