power and sensor data to the OASIS DU. The ASU is connected to the aircraft DC
buss and powers up to two DU's and a MCU. Sensors within the ASU provide for
computation of Indicated Airspeed, Barometric Corrected Altitude, Pressure Altitude
and slip/skid. With the remote Magnetometer Heading information is provided to the
DU. The ASU can have a internal battery that allows operation for a minimum of 1
hour without aircraft power.
