The provided document is a summary of the Pilot's Operating Handbook (POH) for a Cirrus SR-20 aircraft, specifically N699YZ, Serial No. SR-20-2448, revised on 09/11/2018. It covers general information, limitations, emergency procedures, normal procedures, performance data, weight and balance, airplane and systems description, handling, service, maintenance, and supplements related to the Garmin GTX 335-Transponder and GMC 707 Autopilot.

Function Description

The Cirrus SR-20 is a single-engine, low-wing aircraft designed for general aviation. It is equipped with a three-blade, constant-speed Hartzell propeller and a Lycoming IO-390-C3136 engine. A key safety feature is the Cirrus Airframe Parachute System (CAPS), which allows for a full-aircraft parachute deployment in an emergency. The aircraft includes an advanced avionics suite with a multi-function display (MFD) and primary flight display (PFD), and is equipped with a GMC 707 Autopilot for enhanced flight control. The electrical system is robust, featuring two batteries and two alternators to ensure redundancy and reliable power to essential systems.

Usage Features

• Engine Start: Use PRIME for 2 seconds, then BOOST for the fuel pump. Starter motor duty time is 20 seconds on, 20 seconds off.
• Fuel Management: Fuel pump on BOOST for engine start, takeoff, landing, hot fuel conditions, fuel pressure fluctuations, or switching fuel tanks. Fuel tanks filled to tabs provide 26 gallons usable (13 per tank). A FUEL caution light activates when both tanks have approximately 8.5 gallons or less.
• Leaning: In cruise flight at 75% power or less, lean to 100° rich of peak EGT for best power or peak EGT for best economy using the MFD's lean assist or manually.
• Autopilot (GMC 707):
  • Pre-flight tests include checking annunciators, HDG mode, VS mode, ALT hold, overpower, radio check, and disconnect.
  • Operating modes: RDY, HDG, NAV, GPSS, REV, APR, GS, ALT, VS.
  • Disconnect via the "Coolie Hat" button on the control yoke or by pulling the autopilot circuit breaker.
• CAPS Deployment: Airspeed as slow as possible (max 135 KIAS). Remove cover, pull activation handle with both hands straight down in a strong, steady, continuous motion until rocket activates.
• Emergency Procedures: Specific procedures for engine fire in flight, engine failure in flight, engine airstart, partial power loss, propeller governor failure, emergency descent (airspeed at VNE), and open door in flight.
• Taxiing: Directional control maintained with rudder and differential braking. Minimum power for forward movement to avoid brake overheating.
• Alternate Air: Control knob located near the pilot's right ankle on the console. Depress center lock button, pull to open, release button.
• Seating: Front seats are adjustable fore and aft with seat-back tilt. Rear seat backs can be folded down for bulky cargo.
• Lighting: Exterior lights include position, anti-collision, landing, and recognition (Halo) lights. Interior lights include dimmable incandescent instrument bezel lights, red LED flood lights, reading lights, and an overhead dome light.
• Heating and Ventilation: Cabin HEAT, COLD air, and air selector controls manage air temperature and flow to the cabin and windshield defrost.

Maintenance Features

• Oil Dipstick Installation: Point the finger loop toward the airplane's nose or tail, allow it to rotate as it's pushed into the engine.
• Cleaning:
  • Windshield and windows: Linear motion (straight back and forth) to avoid spirals/scratches.
  • Electronic display screens (PFD/MFD): Gently wipe with a clean, dry cotton cloth. Moisten a clean cotton cloth with Optiimax LCD Screen Cleaning Solution, wipe top-to-bottom, then wipe dry.
• ELT: Located behind the aft cabin bulkhead, control panel below the circuit breaker panel. A flashing light on the control panel indicates transmission.
• Hour Meter: Located inside the armrest storage compartment.
• Fire Extinguisher: Visually inspect before each flight for unobstructed nozzle, pin in place, and no canister damage.
• Ground Handling: Tow bar required for pushing backward. Do not push on propeller or tail surfaces; push on wing roots. Nose wheel turning limited to 90° when towed by a vehicle. Minimum radius turn by rotating the airplane on a main landing gear (lift nose wheel by pressing on fuselage forward of horizontal stabilizer).
• Electrical System Monitoring: ALT caution light illuminates for alternator malfunction. Ammeter indicates excessive charge/discharge. LOW VOLTS warning light for voltage 24.5 volts or less. ALT fail caution light flashes for over-current, steady for alternator failure. Volt/Amp meter indicates essential bus voltage, main bus voltages, ALT 1, ALT 2, and BAT 1 amps.
• Circuit Breakers: Pulling circuit breakers is generally discouraged for reducing electrical loads; switch off components instead to prevent accidental disconnection of flight-critical systems.
