(1)
If time permits, use aircraft radio (121.5 MHz) to
transmit distress call; include aircraft position
i f
possible.
After Landing
(1)
Plug Button - REMOVE (located on left side of
tailcone).
(2)
Locator Beacon Switch - ON.
After Rescue
(1)
Locator Beacon Switch - OFF.
ANGLE OF ATTACK SYSTEM
The angle of attack system is a sensitive lift measure-
ment device which provides a continuous evaluation of lift
performance of the aircraft, regardless of weight, wing
loading, attitude, air density, turbulence, and gear/flap
configuration.
The system consists of an indicator, see
Figure 7-5, stall warning horn test switch, computer and lift
sensor.
The lift sensor is located in the leading edge of
the left wing.
The standard aircraft stall warning system is
removed and its function
is
assumed by the angle of attack
system.
For a normal approach to landing, the pointer should be
aligned with the center mark.
Alignment of the pointer with
the "FAST" diamond provides a more comfortable airspeed
margin for an approach in turbulent or gusty conditions.
The red "SLOW" zone on the left side of the indicator
shows the trend toward stall.
The stall warning horn will
sound between 4 and 9 knots above the aircraft stall speed.
To correct for an off-speed condition a small attitude
correction should be held while waiting to see the result on
the indicator.
"Chasing" the pointer may result in a longi-
tudinal pilot induced oscillation.
The instrument is intend-
ed to be used as a reference to assist in determining the
