SYSTEM DESCRIPTION
1.0
SCc
1.1
The Safe Flight SCc Angle of Attack (AoA) System is an accurate wing lift measuring and
display system designed as an aid to help the pilot achieve consistent takeoff, climb, cruise
and landing approach performance. Using a wing leading edge flow measurement device,
the SCc AoA System precisely senses the flow field about the wing’s leading edge. The SCc
AoA indication is accurate regardless of aircraft weight, wing loading, turbulence or wing flap
configuration. This system provides the pilot with AoA-based guidance for high-lift operational
conditions including normal and short-field takeoff, Best Rate (V
y
) and Best Angle (V
x
) of
climb, wind-compensated Long Range Cruise (LRC), maximum endurance, normal and
short-field runway performance, and Low Airspeed (high AoA) Awareness (LAA).
