Mach Airspeed Indicator from Innovative Solutions & Support

The Mach Airspeed Indicator (MASI) is an RVSM compliant unit. In Standby mode, it processes pitot-static pressure, total air temperature, and altitude input data to compute and display calibrated airspeed (CAS), true airspeed (TAS), Mach number, and not-to-exceed airspeed (Vmo) data. In Normal mode, it displays CAS, TAS, ground speed (GS) Mach number, Vmo, and angle of attack (AoA) data provided by the IS&S 9B-81010-22 Digital Air Data Computer (DADC) via ARINC 429.
