Blog 36: Startup and Taxi Procedures for the Cessna 172R

“Getting your engines running and taxiing smoothly is where preparation meets control—a critical step toward a safe flight.” — Aalisha, Student Pilot | Drone Certified | Future PPL | Aviation Blogger

Starting the engine and taxiing out to the runway are foundational skills every student pilot learns early on. For the Cessna 172R, mastering startup and taxiing isn’t just about moving the airplane; it’s a precise process that sets the stage for a safe and efficient flight. Early in my training, following standardized procedures made me feel confident and in command from the moment I turned on the master switch.

In this blog, I'll walk you through the startup and taxi procedures step-by-step, focusing on safety, communication, and smooth control.

Pre-Startup Checks: Before You Fire the Engine

• Complete your external pre-flight inspection (walkaround).

• Verify fuel selectors are on the fullest tank.

• Ensure parking brake is set.

• Set mixture to idle cutoff (full lean).

• Throttle closed slightly (about ¼ inch open).

• Switch all electrical switches off except master switch.

Engine Start Procedure

1. Master Switch On: Powers electrical systems; verify annunciator panel lights.

2. Prime the Engine (if cold): Using the primer knob, inject fuel as recommended in the POH (usually 3-6 strokes).

3. Mixture Rich: Push mixture full in.

4. Throttle: Set to idle or slightly above (approx. 1300 RPM).

5. Magnetos Start: Turn the key to “Start” and hold until the engine fires. Release when engine starts.

6. Monitor Engine Gauges: Oil pressure should rise within 30 seconds, then stabilize; oil temperature should start rising.

7. Adjust Throttle: Set to 1000 RPM for warm-up.

8. Turn Off Auxiliary Electrical Equipment: Avionics master, lights as appropriate.

After Engine Start: Systems and Radios

• Turn on the avionics master and radios.

• Set radio frequencies and transponder code.

• Test flight instruments for correct readings, including heading indicator alignment.

• Complete the “Before Taxi” checklist including flight controls check.

Taxi Procedures

• Release parking brake gently.

• Apply light pressure on the rudder pedals to maintain directional control; nose wheel steering operates at higher taxi speed.

• Use differential braking to assist turns.

• Taxi at a controllable rate—keep it slow enough to stop within available sight distance.

• Follow ATC instructions or airport diagrams carefully when taxiing in controlled environments.

• Scan for obstacles, other aircraft, vehicles, and personnel on taxiways.

Common Taxi Challenges and Tips

• Avoid excessive braking that can cause wear and overheating.

• Watch propeller clearance to avoid objects or personnel.

• Use proper radio calls: “Taxiing to Runway 27 via Taxiway Alpha” to keep ATC informed.

• Practice smooth throttle and rudder inputs to maintain steady control.

My Startup and Taxi Experience

What helped me most was memorizing checklists and rehearsing verbal flows—this reduced stress and allowed me to focus on controlling the airplane rather than forgetting steps. Staying calm and deliberate made every taxi a learning opportunity.

Final Thoughts: A Solid Start Leads to a Successful Flight

Startup and taxi are the first real control inputs on every flight. Treat them with respect, practice routine discipline, and you lay the groundwork for safe flying.

Keep engines humming and wheels rolling smoothly!
