An attitude indicator, also known as a gyro horizon or artificial horizon, is an instrument used in an aircraft to inform the pilot of the orientation of the airplane relative to the earth.
It indicates pitch (fore and aft tilt) and bank (side to side tilt), and is a primary instrument for flight in instrument meteorological conditions.
Attitude indicators also have significant applications under visual flight rules.
The RCA2610 Digital Electronic Attitude Indicator receives digital information from a series of accelerometers which is processed to actuate a display that has two dimensions of freedom, simultaneously displaying pitch and bank.
The display is coloured to indicate the horizon as the division between the two coloured segments (blue for sky and brown for ground), and is intended to be intuitive to use.
Because the RCA2610 has no mechanical gyroscope, it is much more stable than traditional horizons.
The unit is designed to work in 360 degrees of pitch and roll and, unlike a mechanical unit, the RCA2610 can tolerate angles in pitch and roll that would cause a gyroscopic unit to tumble.
On the attitude indicator you will see two yellow horizontal lines with a dot between them.
The horizontal lines represent the wings and the dot represents the nose of the aircraft.
If the symbolic airplane dot is above the horizon line (more blue background) – the aircraft is nose up.
If the symbolic airplane dot is below the horizon line (more brown background) – the aircraft is nose down.
When the dot and wings are on the horizon line, you are in level flight.
If the lines representing the wings roll to the left or the right, the aircraft is probably starting a turn.
The actual bank angle is calibrated around the circumference of the instrument dial.
The pitch angle is indicated by a series of calibration lines, each representing 5° or 10° of pitch.

When you place an order, you should know:
- Instrument model number
- Aircraft voltage (14VAC or 28VAC)
- Panel tilt angle
- When ordering attitude gyros, it is very important that you know the tilt angle of your aircraft’s panel.
- The tilt angle is any deviation from vertical of your control panel in level flight. Installing the incorrect angle will cause the horizon to show a climb or a dive.
- Horizons are set to the correct angle in the factory.
- Check with your aircraft manufacturer if you are not sure what the tilt angle is.
- Lighted or unlighted (lighting voltage)
- Fixed or movable pointer
- Optional slip indicator (additional)
NOTE: There is an extra charge to re-set the tilt angle after purchase.
