Indu Combo indicator is an electronic device, which mimics classical airspeed construction together with altitude and vertical speed. It 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.
We take great care to design our instruments lightweight and slim as possible. Combo only weighs 210 g.
The instrument must be connected to the total pressure source. Total pressure source is obtained from the total port on the pitot tube.
Combo must be connected to the static pressure source. Either fuselage side surfaces or from the static port on the pitot tube.
CAN bus connection
When connected to the bus, Combo will transmit airspeed, altitude and vertical speed data to other units connected to the bus.
A rotating knob is used to adjust the barometric offset (QNH value).
230° linear scale
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 are no standard scales. Scale is custom made for each individual order.
High precision electronic barometric sensor, which provides static pressure information in digital form.
High precision electronic differential pressure sensor, which provides dynamic air pressure information in digital form.
Altitude, variable speed and QNH information is shown on a colour LCD display.
Round slave combo indicator. Requires I-ALT-IAS or EMSIS PFD or NESIS to be present on the CAN bus.
EMSIS can be connected with a backup battery and UPSU electronics. This is wiring schema, which is using double pole switch. This switch is necessary to simultaneously connect/disconnect main power line and backup power line.
