NORMAL - Set the Reference Marker at the center
marker, adjacent to the three-dot center green indication.
Fly the aircraft at the AFM/POH listed airspeed for the
Normal Takeoff. After rotation, climb out using airspeed
as the primary indication. The Indexer Computer will
have the output shown.

TAKEOFF
SYSTEM OVERVIEW
NOTE: If system calibration is required, the red LED on the high side
of the display will blink slowly to signal that calibration is required.
Do not use SCc until a system calibration is completed per 56201-1.
Normal Climb Out

SHORT FIELD - Set the Reference Marker to
correspond to the illustration shown. Fly the aircraft at
the AFM/POH listed airspeed for a Short-Field Takeoff.
After rotation, climb out using airspeed as the primary
indication. The Indexer Computer, when flying using the
Short-Field Obstacle Clearance Takeoff, will have the
indication shown.
LONG RANGE CRUISE - The AoA reference may be adjusted by the
pilot to give a reference that takes the headwind/tailwind component into
consideration for maximum range flight. If the Reference Marker is set
initially for long range cruise as shown in the middle image below, move
the bar down one (1) marker from LRC (no wind) to compensate for a
20 kt. headwind. Move the Reference Marker up one (1) marker from
LRC (no wind) to compensate for a 20 kt. tailwind.

CRUISE
NOTE: This example is not for any particular aircraft make/model and is
only given as an illustration. Consult the aircraft AFM/POH for the
required speed (AoA) bias to be applied to the SCc for your aircraft.

MAXIMUM ENDURANCE - Fly the aircraft at the
speed and attitude consistent with minimum fuel flow.
Set the Reference Marker for the indicated airspeed at
the AFM/POH specified airspeed. This indication will
be constant for the Maximum Endurance AoA as the
aircraft burns fuel.
NORMAL - Fly the aircraft at the speed determined by the FAA-
approved AFM/POH, for the applicable gross weight and flap setting.
When flying this approach speed, the centermark LEDs will be
illuminated as shown below. An under-speed approach is indicated by
the illumination of green or amber LEDS above the ON-SPEED
condition towards the SLOW (high-AoA) side of the display on the
Indexer Computer. An overspeed approach is indicated by the illumi-
nation of the green LEDs below the ON-SPEED condition towards the
FAST (low-AoA) side of the display on the Indexer Computer.

Maximum Endurance Indication
NOTE: The Airspeed Indicator is the primary indication during
approach. The Indexer Computer is to be used as advisory information
only.

LANDING APPROACH

SHORT FIELD - Set the Reference Marker adjacent to
the second green LED above the center ON-SPEED
position. Fly the aircraft at the AFM/POH listed
airspeed for a Short Field Landing Approach. Note the
corresponding Indexer Computer indication.
The SCc AoA System incorporates an LAA function.
When the airplane reaches the near maximum lift
coefficient, the Indexer Computer will display two
flashing red LEDs and an increasing frequency of
“Geiger”-counter-like audio (wired into the aircraft audio
panel and/or pilot headset). The audio will start when the
two amber LEDs are illuminated at a low frequency and
will increase in frequency as the AoA increases.
Top Button: Moves Reference Marker up.
* Holding for 4 seconds, mutes or unmutes LAA audio.
Bottom Button: Moves Reference Marker down.
* Holding for 2 seconds, dims or brightens the display.
* This function is only available with s/n 167304-01 and above and software version 1.3.0 marked on the indexer
nameplate.
LOW AIRSPEED AWARENESS (LAA)

NOTE: The SCc AoA System is not meant to replace the aircraft’s
primary stall warning. The red flashing LEDs and the audio output
are meant to provide a high-AoA warning which is intended to
increase awareness.
