2.1 Cabin Inspection: A.R.R.O.W. Documents and Control Lock Removal

The cabin inspection begins with verifying A.R.R.O.W. documents: Airworthiness Certificate, Registration, Radio License, Operating Handbook, and Weight and Balance. Ensure all control locks are removed, ignition and avionics switches are off, and the cabin is secure. This step ensures compliance with regulations and prepares the aircraft for safe operation, preventing any mechanical or legal issues during the flight. Proper documentation and lock removal are critical for a smooth preflight process.

2.2 Exterior Inspection: Fuel, Control Surfaces, and Tire Condition

The exterior inspection involves checking fuel quantity and cap security, ensuring control surfaces are free from damage, and verifying tire condition and pressure. Inspect for signs of leaks, damage, or wear on wings, stabilizers, and landing gear. Proper inspection ensures the aircraft is airworthy and ready for safe operation, addressing potential issues before they escalate during flight.

• Fuel: Quantity, caps, and vents.
• Control surfaces: Ailerons, elevators, and rudder for damage or malfunctions.
• Tires: Tread depth, pressure, and brake pads.

2.3 Cockpit Setup: Ignition, Avionics, and Trim Configuration

Cockpit setup begins with the ignition switch in the “START” position for engine start. Avionics systems, including GPS, navigation, and communication devices, are powered on and checked for functionality. The elevator trim is set to the “TAKEOFF” position, and the mixture is adjusted to “RICH” for run-up. Ensure all systems are operational and configured correctly for a smooth and safe flight.

• Ignition: START position for engine start.
• Avionics: Power on and verify functionality.
• Trim: Set elevator to TAKEOFF position.
• Mixture: RICH for run-up.

Engine Start and Run-Up Procedures

Set throttle to 1000 RPM, mixture to RICH, and ensure the ammeter and suction gauge are within normal ranges. Perform mag checks and verify smooth engine operation.

• Throttle: 1000 RPM for start.
• Mixture: RICH for run-up.
• Ammeter and suction: Check functionality.
• Magnetos: Verify performance at 125/50 RPM drop.

3.1 Throttle and Mixture Settings for Engine Start

For engine start, set the throttle to 1000 RPM and ensure the mixture is in the RICH position. This setup ensures proper fuel flow and ignition for a smooth start. Verify the fuel selector is on BOTH, and the area is clear before engaging the starter. Monitor the ammeter and suction gauge during startup to ensure normal readings. Avoid sudden throttle movements to prevent engine kick.

3.2 Run-Up Checks: Magnetos, Suction, and Ammeter

During run-up, check the magnetos by observing RPM drops within 125-150 RPM. Ensure suction pressure is between 4.5-5.5 inHg and the ammeter reads 0-50 milliamps. These checks confirm proper engine and electrical system function. Monitor for unusual vibrations or sounds, and verify all gauges are within normal ranges before proceeding with takeoff. This step ensures the aircraft is airworthy and ready for departure.

Takeoff and Climb Checklist

Configure flaps as needed, advance throttle smoothly, and maintain centerline. After liftoff, retract flaps and adjust pitch for optimal climb speed. Monitor instruments and configure fuel selector for optimal performance during ascent.

4.1 Pre-Takeoff Configuration: Flaps, Trim, and Fuel Selector

Ensure flaps are set to 10 degrees for takeoff; Adjust elevator trim for a slight nose-up attitude to reduce control pressure; Select the fuel selector to “BOTH” for optimal fuel flow. Verify the parking brake is set, seatbelts are secure, and throttle is properly configured. These steps ensure a smooth and controlled takeoff, aligning with the aircraft’s performance characteristics and safety protocols outlined in the Cessna 172 Skyhawk checklist.

4.2 Takeoff Roll and Initial Climb Procedures

Advance the throttle smoothly to full power, monitoring for steady RPM and engine instrument readings. Rotate at 55-65 KIAS for liftoff, establishing a positive climb attitude. Retract flaps after takeoff and adjust power for optimal climb performance. Monitor airspeed, oil pressure, and cylinder head temperature. Maintain best rate of climb speed (70 KIAS) until reaching a safe altitude. Configure the aircraft for the desired climb profile and communicate with ATC as required.

Cruise and Descent Procedures

Cruise and descent procedures involve adjusting power settings for optimal performance, monitoring fuel flow, RPM, and temperature, and configuring the aircraft for a smooth descent.

5.1 Adjusting Power Settings for Optimal Cruise Performance

Adjusting power settings for optimal cruise performance involves setting the throttle and mixture for desired RPM, typically around 75% power at 2450 RPM. Monitor engine instruments, ensuring proper fuel flow, oil pressure, and temperature. Lean the mixture for fuel efficiency while maintaining EGT within limits. Propeller pitch should be optimized for cruise conditions. Regularly check fuel consumption and adjust altitude or power as needed to maintain efficiency and performance, referencing the POH for specific guidelines.

5.2 Descent Planning and Configuration

Begin descent planning by reducing power to 1500-1700 RPM to minimize fuel consumption and engine wear. Lower the nose slightly to maintain desired airspeed. Configure flaps as needed, typically at 10-20 degrees for a gradual descent. Ensure the fuel selector is on “BOTH” and monitor altitude and airspeed. Declare intentions and configure for landing, including setting the altimeter. Apply carburetor heat as needed to prevent icing during descent.

Landing and Shutdown Checklist

Lower flaps as needed for approach, ensure seat belts and harnesses are secure. After landing, reduce power to idle, set parking brakes, and taxi carefully. Shutdown engine, switch off avionics and ignition, and secure the aircraft.

6.1 Pre-Landing Configuration: Flaps, Seat Belts, and Harnesses

Configure flaps according to landing conditions, typically 30-40 degrees for a standard approach. Ensure all seat belts and harnesses are securely fastened for all occupants. Verify the cabin is prepared for landing, with loose items stowed and doors closed. Set the fuel selector to the “BOTH” position to ensure fuel flow. These steps ensure a safe and organized landing process, minimizing risks during touchdown and rollout.

6.2 Post-Landing Procedures: Taxi, Shutdown, and Securing the Aircraft

After landing, taxi to the designated area at a safe speed, using brakes sparingly. Ensure the runway is clear before turning. Shutdown the engine by setting the mixture to idle cutoff and turning off the ignition. Secure the aircraft by setting the parking brake, tying it down, and installing control locks. Disconnect electrical systems and ensure all switches are turned off. Complete the post-flight checklist to prepare for the next flight.

Emergency Procedures

The Cessna 172 Skyhawk checklist includes critical procedures for engine failure, system malfunctions, and other emergencies. Pilots must maintain best glide speed, secure the aircraft, and follow specific protocols to ensure safety and minimize risks during unexpected events. These procedures are detailed in the checklist PDFs available for download, providing clear guidance for handling emergencies effectively.

7.1 Engine Failure During Flight: Best Glide Speed and Landing

In the event of engine failure, the Cessna 172 Skyhawk checklist instructs pilots to maintain a best glide speed of approximately 65-70 KIAS to maximize distance. Secure the engine, feather the propeller if equipped, and use the checklist to ensure proper procedures. Identify a suitable landing area, configure the aircraft for landing, and prioritize a safe touchdown. After landing, set the parking brake, cut the ignition, and evacuate if necessary. These steps are critical for minimizing risks and ensuring passenger safety.

7.2 System Malfunctions: Electrical, Hydraulic, and Avionics Issues

In case of electrical system failure, reset circuit breakers and switch to essential power sources. For hydraulic issues, refer to the checklist to isolate the malfunction and use manual overrides. Avionics failures require switching to backup systems and navigating by alternative methods. Always follow the Cessna 172 Skyhawk checklist to address these malfunctions systematically, ensuring continued safe flight operations and minimizing risks. Proper procedure execution is vital.
