ProFAA is the FAA’s computer program for computing pavement elevation profile roughness indexes. ProFAA supports both metric and English units. Data analysis performed by the program includes the simulation of aircraft response and the calculation of the following associated indices: Straightedge Simulation, Boeing Bump Index, International Roughness Index, California Profilograph, root mean square bandpass profile. ProFAA’s aircraft simulation can simulate representative commercial aircraft and output acceleration and gear force responses.
