Rudder and Trim

Yaw and Trim

You've already met pitch and roll. Today you finish the set with yaw, and you learn a trick that makes flying easier.

Yaw

This is the nose swinging left or right, like shaking your head "no." The foot pedals do it. Press the left pedal and the nose swings left; press the right pedal and it swings right. The panel that does this is the rudder on the tail.

Trim

A small wheel that holds the nose where you set it. Once you trim, the airplane keeps its attitude on its own, so you don't have to keep pulling or pushing.

Trim is like cruise control for the airplane — it holds the nose where you want it so your arms do not get tired. Good pilots use the yoke, the pedals, and trim all together to fly smoothly.

Instructor Setup

Place the Cessna 172 G1000 airborne, trimmed, straight and level at 4,000 feet. Plan about 20 minutes. Point out the rudder pedals and the trim wheel before the student touches anything.

Session Flow

1. Recap pitch and roll (3 min). A quick re-fly of K02 yoke inputs and the controls handoff.
2. Demonstrate yaw (5 min). Show left and right rudder and the nose swinging; have the student try each pedal and watch the nose.
3. Demonstrate trim (5 min). Roll the trim wheel, show how the yoke pressure disappears, then let the student trim and briefly let go of the yoke.
4. Coordinated turn (5 min). Coach a gentle left turn using yoke and rudder together.
5. Wrap (2 min). Recap yaw and trim and preview "Start the Engine."

Keep banks shallow and inputs gentle. The goal is the feel of all three controls working together.

Debrief

Confirm the student can use the pedals and trim before moving on.

• Pressed left and right rudder and saw the nose yaw the matching way
• Used the trim wheel to relieve pressure on the yoke
• Trimmed well enough to briefly fly with a light touch
• Flew a gentle turn using yoke and rudder together

Next Lesson

Next up is "Start the Engine" (K04): bringing the airplane to life from a cold-and-dark cockpit using the checklist. If trim still feels confusing, take two minutes at the start of K04 to revisit it on the ground.

Skills You'll Work On

These are the maneuvers and procedures covered in this lesson. Your instructor tracks each one as you progress.

• Effects of Rudder
• Use of Trim
• Further Effects of Controls

Grades reflect what was covered in this lesson, not a certification of pilot competency.

Lesson Plan

Where this fits: Third of three sessions drawn from PPL Lesson 1, "Effects of Controls." This session covers the rudder (yaw) and the use of trim, completing the primary controls introduced across K01–K03.

Prerequisite

K02 — Make It Move (can produce pitch and roll with the yoke).

Materials

C172 G1000 simulator set up airborne at 4,000 feet, student checklist card, headset.

Goal for this session

Student can produce yaw with the rudder pedals, use trim to relieve control pressure, and fly a coordinated gentle turn.

Looking Ahead

• K04 — Start the Engine: the cold-and-dark engine start checklist.
• K05 — Taxi Practice: steering on the ground with the feet.
