Climbing

Purpose

To climb at a specified airspeed, in various configurations, and to level off at a specified altitude.

Airmanship

Good airmanship during the climb requires constant vigilance and awareness of several factors:

• Lookout: The nose-high attitude in a climb restricts forward visibility. Weave the nose gently left and right every 500 feet of altitude gain, or dip the nose periodically, to check for traffic ahead and above.
• Engine monitoring: Keep a regular scan of engine temperatures and pressures. The combination of high power and reduced cooling airflow makes the climb a demanding phase for the engine.
• V_FE awareness: If any flap is extended, be aware of the maximum flap extended speed and ensure you do not exceed it during the climb or subsequent acceleration.
• Altimeter awareness: Monitor your altitude continuously so you can begin the level-off procedure at the correct anticipation point.

Entering the Climb

The transition from level flight to a climb follows the Power-Attitude-Trim sequence:

1. POWER: Smoothly apply full power (or the recommended climb power setting). Check the engine instruments respond normally.
2. ATTITUDE: Simultaneously raise the nose to the climb attitude. Use the horizon as your primary pitch reference — the attitude that gives you the target climb airspeed (V_y for a normal climb).
3. TRIM: Once the airspeed has stabilized at the target value, trim away the control pressure. This reduces your workload and allows you to hold the climb attitude with minimal effort.

As power is applied, the airplane will yaw to the left due to engine torque effects. Apply right rudder pressure to maintain coordinated flight — check the ball remains centered.

Maintaining the Climb

Once established in the climb, your priorities are:

• Airspeed control via attitude: If the airspeed is too high, raise the nose slightly. If too low, lower it. Small corrections are key.
• Wings level: Use the attitude indicator and external references to keep wings level. Any bank reduces the vertical component of lift and degrades climb performance.
• Balanced flight: Keep the ball centered with rudder pressure. Uncoordinated flight creates additional drag and reduces climb efficiency.
• Engine monitoring: Regularly scan CHT, oil temperature, and oil pressure. If temperatures approach limits, consider transitioning to a cruise climb for better cooling.
• Altimeter scan: Include the altimeter in your scan to know when to begin the level-off.

Leveling Off

The transition from a climb to level flight follows the Attitude-Power-Trim sequence. Begin the level-off by anticipating your target altitude:

1. ATTITUDE: Smoothly lower the nose to the level flight attitude as you approach the target altitude.
2. POWER: As the airspeed accelerates toward cruise speed, reduce power to the cruise setting.
3. TRIM: Once airspeed and altitude have stabilized, trim to relieve any control pressure.

Allow the airplane to accelerate in level flight before reducing power. This technique ensures a smooth transition and avoids altitude go-around.

Effect of Flap

Climbing with flap extended (for example, after a short-field takeoff) results in:

• A lower rate of climb due to increased drag
• A lower nose attitude for the same airspeed (more lift at a given angle of attack)
• A need to retract flaps incrementally once at a safe altitude and airspeed, following the POH procedure

When retracting flaps during the climb, do so in stages. Each stage of flap retraction will momentarily reduce lift, so anticipate a slight sink and compensate with a small pitch increase.

Best Angle of Climb (V_x)

When obstacle clearance is required — such as departing a short field with trees at the far end — fly at V_x to achieve the steepest climb path:

• The airspeed is slower than V_y, requiring more precise attitude control
• The nose attitude is higher, further reducing forward visibility
• Stall margin is reduced — maintain airspeed vigilantly
• Engine cooling is reduced — transition to V_y as soon as obstacles are cleared

Cruise Climb

The cruise climb uses an airspeed higher than V_y — typically near cruise airspeed with climb power set. The technique is straightforward:

• Nose attitude is only slightly higher than level flight — providing excellent forward visibility
• Cruise airspeed (or near it) is maintained, giving better engine cooling
• Rate of climb is reduced, but the relaxed pitch attitude makes for a comfortable, sustainable climb
• Ground speed is higher, making this technique ideal for cross-country flights where obstacle clearance is not a concern

Use the cruise climb when traffic, terrain, and ATC permit a more gradual ascent to your cruising altitude.
