indication marked on the instrument panel. The aileron trim also
provides a secondary means of aircraft roll control in the event of a
failure in the primary roll control system not involving jammed ailerons.
Aileron trim operates on 28 VDC supplied through the 2-amp ROLL
TRIM circuit breaker on Main Bus 1.

Yaw Trim System
Yaw trim is provided by spring cartridge attached to the rudder pedal
torque tube and console structure. The spring cartridge provides a
centering force regardless of the direction of rudder deflection. The
yaw trim is ground adjustable only.
On airplanes with electric rudder (yaw) trim, trim changes are pilot
controlled through a linear actuator connected to a hinged trim tab on
the rudder trailing edge. The actuator is installed in the rudder. A
RUDDER TRIM indicator with integral rocker switch is mounted in the
console immediately adjacent to the FLAP control switch. Pressing the
left half of the switch initiates Nose L trim and pressing the right half
initiates Nose R trim. A needle sweeps the trim indicator scale to
indicate trim position. The full Nose Right trim tic is labeled TAKEOFF.
Rudder (yaw) trim operates on 28 VDC supplied through the 2-amp
PITCH / YAW TRIM circuit breaker on Main Bus 1. The switch and
indicator are not internally illuminated.

Flight Deck Arrangement
The following paragraphs are a general description of the flight deck,
instrumentation, and controls. The instrument panel is designed for
glare-free use in all flight conditions. The instrument panel is arranged
primarily for use by the pilot in the left seat; however, it can be viewed
from either seat. For details relating to the instrumentation, switches,
circuit breakers, and controls on the instrument panel, bolster, and
center console, refer to the related topics in this section.
Instrument Panel
Serials 0002 through 1601, 1603 through 1643 and 1645 through
1662 without PFD: Flight instruments and annunciators are located on
the left side of the panel and engine instruments are located on the
right side of the instrument panel. A large color multifunction display is
located between the flight instruments and the engine instruments.
Temperature controls are located on the right side below the engine
instruments.
The SR22 uses standard flight instruments arranged in the 'basic-six'
pattern. They include:
Serials 0002 through 0434, an electronic clock and VOR/LOC/ILS
(CDI) are located immediately to the left of the flight instruments on the
instrument panel.
A switch panel located in the “dash board” bolster below the flight
instruments contains the master and ignition switches, avionics power
switch, pitot heat switch, and lighting switches.

SR22 Airplane Description
Serials 0435 and subsequent with PFD: The airplane is equipped with
an Avidyne FlightMax Entegra-Series Primary Flight Display (PFD).
The PFD is a 10.4” landscape-oriented display intended to be the
primary display of primary flight parameter information (attitude,
airspeed, heading, and altitude) to the pilot. The PFD accepts data
from a variety of sources, including the GPS sensors, the System 55X
Autopilot, and is the primary heading source for the Multifunction
Display.
Standby altimeter, airspeed, and attitude indicators are mounted on
the bolster panel in case of total or partial PFD failure. To provide roll
data to the autopilot system, a Turn Coordinator is mounted behind the
RH bolster panel.
Annunciators and the ignition switch are located on the left side of the
panel and a large color multifunction display is located adjacent to the
primary flight display. Temperature controls are located on the right
side below the glove compartment.
A switch panel located in the “dash board” bolster below the flight
instruments contains the master switch, avionics power switch, pitot
heat switch, and lighting switches.
Center Console
A center console contains the avionics, flap control and position lights,
power lever and mixture controls, fuel system indicator and controls,
and audio controls. System circuit breakers, the alternate static source
valve, alternate induction air control, and ELT panel switch are located
on the left side of the console for easy access by the pilot. A friction
