Cockpit Checks

The cockpit is where the magic happens, and it's crucial to make sure everything is in order before you even think about starting the engine. You want to ensure every switch, gauge, and control is functioning correctly. This is your command center, and a thorough check here can prevent potential problems later on.

1. Documents and Placards

First things first, let's verify that all the necessary paperwork is onboard and up-to-date. This includes the Airworthiness Certificate, Registration Certificate, Operating Limitations, and Weight and Balance information. Confirm that these documents are easily accessible and haven't expired. Imagine taking off only to realize your registration expired last month – not a situation you want to be in! Also, make sure that all required placards are present and legible. These placards provide essential information about aircraft operations and limitations, so they need to be in plain sight.

2. Control Locks

Remove the control locks! This might seem obvious, but you'd be surprised how many pilots have attempted to taxi or even take off with the control locks still engaged. Double-check that the ailerons, elevator, and rudder are free to move without any obstruction. Ensure that the control column moves smoothly throughout its entire range of motion. Any stiffness or resistance could indicate a problem with the control system. It's also a good idea to check the rudder pedals for free movement and proper adjustment.

3. Master Switch and Battery

Turn on the master switch and check the battery voltage. The voltage should be within the normal operating range, typically around 24 volts for a 24-volt system or 12 volts for a 12-volt system. A low voltage reading could indicate a weak battery or a problem with the charging system. Also, verify that the ammeter shows a charge when the engine is running. If the battery is not charging, it could lead to a complete electrical failure during flight.

4. Avionics and Radios

Test all avionics and radios. Turn on each radio and listen for static or a test signal. Verify that you can transmit and receive on both VHF radios. If you have a GPS unit, make sure it's receiving a signal and that the database is current. Check the navigation equipment, such as VOR and GPS, to ensure they are functioning correctly. It's also a good idea to tune into a local ATIS or AWOS frequency to get the latest weather information. Confirm the autopilot is functioning correctly if equipped.

5. Fuel Selector and Quantity

Select the proper fuel tank and check the fuel quantity. Ensure that the fuel selector valve is set to the correct tank and that there is sufficient fuel for the planned flight, plus required reserves. Visually inspect the fuel quantity gauges and compare them to the fuel totalizer if equipped. It's also a good practice to sump each fuel tank to check for water or contaminants. Water in the fuel can cause engine problems, so it's essential to catch it before takeoff.

6. Flight Controls

Confirm full and free movement of all flight controls. This step is similar to checking the control locks, but now you're verifying the full range of motion of each control surface. Move the ailerons, elevator, and rudder through their entire range of travel and ensure they respond correctly. Check for any binding or unusual resistance. Also, inspect the control cables and linkages for any signs of wear or damage.

Exterior Checks

Okay, time to step outside and give the Archer III a thorough once-over. This is where you'll be looking for any visible damage, leaks, or other issues that could affect the aircraft's performance or safety. Don't rush this part; a careful inspection here can save you a lot of trouble in the air.

Look for any evidence of bird strikes or other impacts. If you find any damage, consult with a qualified mechanic before flying the aircraft. Remember, even a small dent can affect the aircraft's aerodynamics.

2. Empennage

Examine the empennage (tail section) for any damage or loose components. Check the horizontal and vertical stabilizers for cracks, dents, or corrosion. Ensure that the elevator and rudder are securely attached and move freely. Inspect the trim tabs and their associated linkages. Also, check the tail tie-down and make sure it's properly secured.

3. Landing Gear

Check the landing gear for proper inflation and condition. Inspect the tires for wear, cuts, or bulges. Make sure the wheel fairings (if installed) are securely attached. Check the brake lines and calipers for leaks. If the aircraft has retractable landing gear, verify that the gear is properly extended and locked. It's also a good idea to check the wheel bearings for excessive play.

4. Engine Compartment

Inspect the engine compartment for leaks, loose wires, and proper fluid levels. Check the oil level using the dipstick and add oil if necessary. Look for any signs of fuel or oil leaks around the engine. Inspect the spark plug wires for proper connection and insulation. Verify that all hoses and clamps are secure. Also, check the air filter for cleanliness and replace it if necessary.

5. Propeller

Examine the propeller for nicks, dents, and security. Check the propeller blades for any signs of damage, especially along the leading edges. Ensure that the propeller spinner is securely attached. If the aircraft has a constant-speed propeller, verify that it cycles smoothly during the engine run-up. Also, check the propeller governor for leaks.

6. Fuel Vents and Drains

Check the fuel vents and drains for obstructions and contamination. Make sure the fuel vents are clear to allow proper airflow into the fuel tanks. Sump each fuel drain to check for water or sediment. Water in the fuel can cause engine problems, so it's crucial to remove it before flight. Also, check the fuel caps to ensure they are properly sealed.

Before Start Checklist

Alright, back in the cockpit! Time for the Before Start checklist. This is where we make sure everything is set up correctly for engine start. Let's get this done!

1. Seats and Belts

Adjust seats and fasten seat belts and shoulder harnesses. Ensure that your seat is properly adjusted so you can reach all the controls comfortably. Fasten your seat belt and shoulder harness securely. Make sure your passengers also have their seat belts and shoulder harnesses fastened. A properly secured seat belt can save your life in the event of an accident.
