Introduction

The ASI-4 is a 2 1/4” 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-4 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-4 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-4 instrument measures airspeed from 16mph to 250mph and is well suited to slower aircraft due to very good

sensitivity and linearity at low air speeds.

3.1 Maximum Airspeed display

This display can be accessed by rotating the rotary control during the normal display

mode. Press the F1/Up button when the max values display is showing to reset the

maximum values to the current airspeed.

3.2 Start / Stop flight display

Press the F1/Up button during the normal display mode

to manually start/stop a flight. This key is only active if

the ASI-4 is setup to select the manual flight option

under the “TIMERS” setup menu.

Note: The maximum airspeed is stored in non-volatile

memory and is recalled on power-up.
