The AIMMS-20 (Airborne Integrated Meteorological Measurement System) is a canister-mounting probe flown on the FAAM BAe-146 aircraft. Its primary purpose is to provide high-frequency measurements of 3-d wind vector components in icing conditions, where the Core radome turbulence system would be expected to ice-up. The probe comprises a 5-port differential pressure sensor to measure flow velocity relative to the aircraft (true airspeed and angles of attack/sideslip) and a combined GPS/inertial system to measure the velocity and attitude of the aircraft relative to the ground.
