Comments:NASA Goddard’s Scanning L-band Active Passive (SLAP) instrument suite consists of a rotating L-band radiometer (passive) and radar (active) nadir-mounted within a custom aerodynamic fairing on the NASA Langley UC-12B Huron aircraft (see attached figures). The diameter of the antenna is 46.08 in. The antenna rotates at 12 rpm. The instrument utilizes the existing forward research nadir port. The goal of this flight experiment is to measure soil moisture from an airborne platform utilizing the SLAP instrument. A taxi evaluation and three compatibility flight profile evaluations of the SLAP instrument and its associated aerodynamic fairing were conducted on November 22 and 25, 2013, respectively. The first two evaluation flights evaluated longitudinal, lateral and directional flying qualities, a roll evaluation for the SLAP sky-pointing maneuver, as well as simulated single-engine tests, stall evaluations and trim control power tests. Airspeed and altimeter calibrations were conducted against the NASA Langley SR22 safety chase aircraft at a variety of airspeeds. During the second evaluation flight, a maximum airspeed with the fairing installed of 190 KIAS was established. The third evaluation flight consisted of multiple landings. No unacceptable flying qualities were noted and very minimal performance changes were noted from the normal UC-12B handling qualities. The fairing was removed for inspection following the third evaluation flight and no failures or faults were discovered. In conclusion, RSD considers the compatibility flights complete with no limiting parameters established other than the maximum tested airspeed of 190 KIAS. The pilots for these flights were Richard J. Yasky, Jr., Head, Operations and Engineering Branch, Research Services Directorate (RSD), and Gregory L. Slover, RSD, NASA Langley. The photographer in the SR22 chase aircraft was Michael S. Wusk, OEB/RSD.
