3.3 FLIGHT LIMITATIONS
There are no ight limitations to the RCA 2600 Series horizon. The instrument will operate in a full 360 degrees of turn and may be
used in light aerobatic type maneuvers.
Extreme turns may cause the instrument display to temporarily disable itself. This is indicated by a red “X” across the screen and
an “Exceed Bank Angle” warning notice at the bottom of the screen. The instrument should automatically reset the display within
3 to 10 seconds. This situation is due to the speed the processor repaints the display. The attitude sensors are not affected so it is
not necessary to level the aircraft while the display resets. Unlike mechanical gyros, extreme maneuvers will not cause any harm to
the instrument.
3.4 EMERGENCY PROCEDURES
In the rare event that your RCA 2600 does not reset itself, you will need to pull power to the unit and reset the circuit breaker. This
will restart the unit and you can continue on without damage to the unit. You do not need to be ying level while the unit resets.
In a low voltage situation, the RCA 2600 will show a “Low Voltage” warning notice at the bottom of the screen. This notice will
appear when the voltage goes below 11 volts. This notice will also indicated the amount of voltage the instrument is receiving. At
8.5 volts, a red “X” will appear across the screen indicating that the instrument reading is unreliable.
It is recommended that you install the Kelly Manufacturing ESP-1 (Emergency Standby Power) backup battery unit. This will
ensure that your instrument will have power in the event of Aircraft power failure. Contact your R.C. Allen/Kelly Mfg. distributor for
additional information about this product.
SECTION 3, OPERATION GUIDE
3.1 PRE-FLIGHT PROCEDURES
During pre-ight procedures, the instrument must be provided with adequate electrical power under normal vibration conditions
(engine running). A red “X” appears across the screen indicating that the instrument is booting up. When the X disappears, the
instrument is ready. The startup process should be completed within three minutes.
NOTE
On tail-dragger aircraft, the indicator will not show as level until after achieving level ight. No adjustment are
necessary when level ight is achieved.
3.2 IN-FLIGHT PROCEDURES
In ight, you do not need to cage the unit as you would a mechanical gyro. It will indicate accurately at all times. You may adjust the
screen brightness (DIM button) at any time (See gure 3.1 for dimming controls). Press and hold up or down button until you reach
desired brightness and release. Press both buttons simultaneously to reset to factory default setting.
