Introduction
The ASI-5 is a 3 1/8” (80mm) sunlight readable instrument that provides a wide range airspeed indication in both digital
and analog tape formats. Airspeed is based on the pressure generated by a pitot tube system and a static port is provided
as well for use by high speed aircraft. In addition, the ASI-5 provides a flight timer since takeoff and records the maximum
airspeed reached.
Airspeed can be indicated in statute miles per hour (mph), kilometers per hour (km/h) or nautical miles per hour (kts). The
analog airspeed tape can be scaled according to the aircraft’s flying speed range and ranges for Vs0, Vs1, Vfe, Vno and
Vne can be set. The ASI-5 also provides a programmable Vs and Vne airspeed alarm output. ASI sensitivity can be
calibrated by the user to cater for errors caused by pitot tube placement.
The ASI-5 can measure airspeed from 20mph to 250mph (Version 1), 20mph to 350mph (Version 2) and 20mph to
320mph for the ASI-5HS (High Speed version). All are well suited to slower aircraft due to very good sensitivity and
linearity at low air speeds.
Please note that the ASI-5 Version 2 replaces both the ASI-5 Version 1 and the ASI-5HS (High speed) unit.
