SYSTEMS

Power Distribution - depicts the contactors and bus feeds.  Features include:

• Use of fuses and fusible links instead of breakers for ease of installation, cost, and complexity.  Only use of breakers is on the alternator feed circuits since these are resettable;

• An Avionics Master switch and bus.  I do this for convenience.  It is essentially an endurance bus with the alternate feed switch; and

• Single battery with dual alternators.

Alternator - depicts the alternators and controllers.  Features include:

• Dual alternators concurrently feeding the bus and battery;
• Dual alternator controllers with warning circuits; and
• Use of LEDs instead of bulbs for all warning lights.

Pitot Heat - depicts the heated pitot tube in the left wing.  Features include:

• Use of a wing disconnect fitting for all electrical connections in the wing; and
• Use of the main spar as a grounding point with a direct connection to firewall ground block.

Fuel Pump – depicts the fuel pump in the center tunnel.  Features include:

• Use of a disconnect fitting near the pump to facilitate removal.

Flaps – depicts the flap circuit with flap control board.  Features include:

• Use of a flap control board so that a micro-switch in the control stick can be used to control the flaps; and
• Use of a terminal strip in the center tunnel to facilitate removal of the control stick.

Trim Systems – Depicts the trim motors, control stick switched and indicators.  Features include:

• Use of a disconnect fitting in the tail to facilitate elevator removal;
• Servo speed controller;
• Use of control stick buttons to control trim; and
• Use of a terminal strip in the center tunnel to facilitate removal of the control stick.

Start – depicts the magnetos and associated switches.  Features include:

• Use of toggle switches instead of a key switch for starting;
• Starter engaged warning lights in case of stuck contacts/starter;
• Use of LEDs instead of bulbs on the warning circuit; and
• Single magneto with one electronic ignition module.

Fuel Tank Reminder – depicts timer, chime, and lights to remind pilot to switch tanks.  Features include:

• Variable timer circuit board from 1 to 60 minutes.

Seat Heaters – depicts dual unit, front and back seat heaters.  Features include:

• Dual electric heaters for each seat;
• High/low toggle switches for different heat setting; and
• Non-latching relay turns heat off when ignition turned off.

EFIS/AHRS – depicts dual EFIS units with AHRS and magnetometer.  Features include:

• Dual screen EFIS units from GRT;
• Full integration with engine monitor, GPS, and autopilot; and
• Interconnect between displays so one can backup the other.

Engine Monitor – depicts GRT engine monitor.  Features include:

• Six cylinder CHT and EGT probes;
• Fuel flow analyzer; and
• full integration with EFIS.

Autopilot – depicts controller and servos.  Features include:

• Control stick push button to engage/disengage autopilot; and
• Full integration with EFIS

Landing Lights – depict landing lights mounted in each wingtip.  Features include:

• Disconnect fittings near the fixture to facilitate wing tip removal;

• Use of a wing disconnect fitting for all electrical connections in the wing; and

• Use of the main spar as a grounding point with a direct connection to firewall ground block.

Strobe Lights – depict strobe fixtures in each wingtip and tail, and power supply.  Features include:

• Disconnect fittings near the fixture to facilitate wing tip removal;
• Proper grounding of wire runs to eliminate noise; and

• Use of a wing disconnect fitting for all electrical connections in the wing.

Position Lights – depicts light fixtures in each wingtip.  Features include:

• Disconnect fittings near the fixture to facilitate wing tip removal;

• Use of a wing disconnect fitting for all electrical connections in the wing;
• Use of the main spar as a grounding point with a direct connection to firewall ground block; and
• Position light switch used to activate trim indicator lights instead of panel light circuit.

Panel Lights – depicts solid-state dimmer and potentiometer.  Features include:

• Use of a terminal strip to balance light loads across circuit; and
• “Always On” lighting circuit which protects bulbs and increases bulb life.

GPS/NAV/COMM – depicts Garmin GNS430.  Features include:

• Full integration with EFIS, transponder, and intercom.

Transponder – depicts Garmin GNX327.  Features include:

• Full integration with GPS and EFIS.

• EFIS supplies blind encoder altitude to transponder;
• Transponder supplies altitude data to GPS;
• EFIS supplies fuel/air data to GPS for RAIM integrity checking;
• EFIS controls autopilot; and
• GPS provides map and other aviation data to EFIS for display
