The Aerosonic Sensor Unit (ASU) of the SFI accepts pitot (total) and static pressure input from which Pitot/Static System?

The Aerosonic Sensor Unit (ASU) of the SFI accepts pitot (total) and static pressure input from which Pitot/Static System?

• A. Pilot's/No. 2
• B. Pilot's/No. 1
• C. Co-Pilot's/No. 1
• D. Co-Pilot's/No. 2

Answer: (A)

The ASU needs a source of both total (pitot) pressure and static pressure to compute airspeed and other air-data signals. In the MH-65E, there are two pitot-static networks, designated for the Pilot and Co-Pilot stations, with No. 1 and No. 2 circuits. The Aerosonic Sensor Unit is wired to the Pilot’s No. 2 Pitot-Static System, so it receives total pressure and static pressure from that specific channel. This dedicated input provides the ASU with a stable, known source for air data and helps keep its readings independent from the other systems that use No. 1 or the Co-Pilot circuits. Therefore, the Aerosonic Sensor Unit accepts pitot (total) and static pressure input from the Pilot’s No. 2 Pitot-Static System.
