INDU Airspeed — Manual
1. Introduction

Introduction
First of all, we would like to thank you for purchasing our device. Indu airspeed is an electronic
device, which mimics classical airspeed construction and combines it with the state of the art
electronics. This results in the best of both worlds; a perfect and intuitive analogue reading
combined with high precision of modern electronics.
This manual describes the technical description of the unit, installation and operation.
1.1
General Description
The airspeed is an electromechanical device. It consists of high precision electronic differen-
tial pressure sensor, which provides dynamic air pressure information in digital form. The
electronics reads the sensor and drives stepper motor turning a needle. Airspeed information
is also shown on a colour LCD display. When connected to a CAN bus the airspeed outputs
airspeed and OAT

data which can be used by other
Kanardia
devices.
Display is divided linearly in 230
◦
scale with colour LCD display in the center. Scale is custom
made and must be specified when ordering the device.
There is a special version
1
of airspeed indicator that can display true airspeed (TAS) and
outside air temperature (OAT) information on LCD display. This requires an external OAT
probe to be connected to airspeed and an Indu Altimeter to be present on same CAN bus.
