3 1/8" Velocity Singles

We combine the most advanced and miniaturized components for magnetic field and intertial measurement in a compact format weighing in at less than 150 grams.

We use our AV-1 airtalk computer, a Stratomaster Infinity Single programmed with an application program that lets you choose what you want to display. Horizon, Turn & Bank, or a compass - as you wish, and each mode has options and additional, useful functions.

The display options depend on the attitude / heading sensor package you select...

Attitude/Heading Sensors:

Depending on what attitude / heading sensor packages you choose, you will have the following features on your instrument:
 
 

SP-2 Sensor: Tilt-compensated magnetic compass SP-4 Sensor: Attitude indication and turn/bank indication

What else can you do?

With the SP-4 and SP-2 sensor packages you can add additional AV-1 Infinity Singles (or even 3 1/8” AV-2 Maxi Singles) for separate Compass and Turn/Slip Indicators.

Or how about one SP-4 and one SP-2 unit and six AV-1/AV-2 displays? Yes, you can have two Horizons, two Turn/Slips and two Compasses all at the same time. Makes a dual cockpit layout interesting...
