Straight Climbs and Climbing Turns

Demonstrate and simultaneously explain how to establish, maintain, and level off from climbs and climbing turns, plus analyze and correct common errors (AI.VIII.C.S1, S2). "Level off from" is the half applicants under-brief. The evaluator must select at least one Task from Area VIII; if you draw this one, the level-off narration is where a weak applicant goes quiet.

To climb, the wing must develop excess lift to overcome weight. More lift means more induced drag, which either costs airspeed or demands more power to hold the climb speed. So an airplane can only sustain a climb when there is sufficient thrust to offset the increased drag — climb rate is limited by excess thrust available (AFH ch. 3). Corollary the student needs: the thrust that held level flight at a given airspeed is not enough to hold that same airspeed in a climb.

Per AFH ch. 3:

• Normal (cruise) climb — the manufacturer's recommended climb speed, generally higher than best rate. The extra speed buys better engine cooling, greater control authority, and better visibility over the nose.
• Best rate of climb (Vy) — most altitude gained per unit of time; the normal departure climb from an unobstructed runway until it is safe to transition to cruise climb.
• Best angle of climb (Vx) — most altitude gained per unit of horizontal distance. Steeper, but it takes longer to reach a given altitude than Vy. Used to clear an obstacle, such as trees off the departure end.

Vx increases and Vy decreases as altitude increases (AFH ch. 3). They converge at the absolute ceiling — the altitude at which the airplane can no longer climb. Always send the student to the AFM/POH performance charts for the correct speed at the actual conditions rather than a memorized sea-level number. This is a favorite examiner follow-up because a student who memorizes two numbers has learned a fact instead of a concept.

Gently increase back pressure to the climb pitch attitude referencing the nose against the natural horizon, while simultaneously advancing to climb power (AFH ch. 3). Then:

• Reference the wingtips to hold the climb attitude wings-level; cross-check the instruments to verify performance.
• Expect increased slipstream over the horizontal stabilizer as power comes up — in many airplanes the nose pitches up more than desired, so be ready with the pressure to hold the attitude you actually want.
• As airspeed decays into the climb, the nose tends to lower unless you add elevator pressure. Hold the attitude, then trim nose-up so you are not holding it.

Elevator pressure — because power is fixed at the climb setting (AFH ch. 3). The pitch attitude against the natural horizon determines whether the attitude is correct; the flight instruments are then cross-checked to verify climb performance. State it that way to the student, because the reflexive instinct is to chase the airspeed needle with the yoke, which is common error number one on this Task.

Two of the four left-turning tendencies dominate at high power and high AOA (AFH ch. 3; PHAK ch. 5). P-factor: at increased pitch attitude the descending blade (the right side of the disc from the flight deck) has a higher AOA, so the center of thrust moves right, yawing the nose left. Torque reaction: Newton's third law — the engine and prop turning one way rolls the airplane the other way, left. Correction is right rudder and right aileron pressure. Tell the student it will "seem awkward at first" and that it becomes instinctive with experience — the AFH says exactly that, and hearing it normalizes the discomfort instead of making them think they are failing.

"Torque," as the term is used to a pilot, is made up of four elements (PHAK ch. 5):

1. Torque reaction from engine and propeller — rolls the airplane opposite prop rotation.
2. Corkscrewing effect of the slipstream — the spiraling slipstream strikes the vertical fin, yawing the nose left; most compact and most powerful at high prop speed and low forward speed, and it elongates and weakens as airspeed increases.
3. Gyroscopic action (precession) — an applied force takes effect 90° ahead in the direction of rotation.
4. Asymmetric loading (P-factor) — at high AOA the descending blade takes a bigger "bite."

Useful nuance for a sharp student: the slipstream's rolling moment is to the right, while torque reaction's is to the left, so they partly cancel — but the forces vary greatly and it is the pilot's job to correct whichever dominates at the moment.

Begin the level-off at approximately 10 percent of the rate of climb below the target altitude — climbing at 500 fpm, start leveling 50 feet early (AFH ch. 3). Then:

1. Lower the pitch attitude smoothly and slowly to let the airspeed build; changing pitch too fast without letting speed increase loses altitude.
2. Retain climb power temporarily while the airplane accelerates.
3. Only when cruise airspeed is reached, set cruise power (and prop, if equipped) and re-trim.

Students almost universally pull power at the altitude and then wallow.

Three things the AFH wants said (ch. 3):

• At a constant power setting you cannot hold the same pitch attitude and airspeed banked as you can in a straight climb, because total lift required has gone up — the airplane climbs at a shallower climb angle since some lift is being used to turn.
• Steep bank significantly decreases the rate of climb; hold an appropriate constant bank.
• Maintain a constant airspeed and constant rate of turn in both directions — control coordination is the primary factor.

Everything from level turns still applies: lateral stability or overbanking, adverse yaw, propeller effects, reduced vertical lift, and increased drag. Because the turn's lost vertical lift stacks on top of the climb's demand, the climbing turn needs additional elevator back pressure. Limit simultaneous climbing turns to shallow bank — that "provides for an efficient rate of climb," whereas, in the AFH's full sentence, "if a medium or steep banked turn is used, climb performance is degraded or possibly non-existent."

Because in a climb the wing's lift vector is no longer perpendicular to the flightpath in the way it was in level flight, and part of the requirement is picked up by a vertical component of thrust from the powerplant — which is why power must be advanced to the recommended climb setting (AFH ch. 3). Weight is a constant for practical purposes; the climb is bought by adding energy, not by re-pointing existing energy. Students who try to climb on pitch alone get a decaying airspeed and a lesson in why that fails.

Normally aspirated engines lose power as altitude increases because air density decreases — shown as decreasing rpm with a fixed-pitch prop, or decreasing manifold pressure with a controllable prop (AFH ch. 3). So:

• Continually advance the throttle during the climb to maintain the specified climb setting.
• With an independently controllable-pitch prop, advance the propeller control before increasing engine power.
• Where cowl flaps are fitted, set them to keep cylinder head temperatures within the manufacturer's specifications.
• Cross-check the engine instruments so pressures and temperatures stay within limits.

For a first-lesson student in a fixed-pitch trainer this collapses to "watch the rpm sag and push the throttle up," but you owe the examiner the general case.

Sequential entry is the better teaching order — establish the climb, stabilize it, then add bank — even though the AFH allows either approach: climbing turns "may be established by entering the climb first and then banking into the turn, or climbing and turning simultaneously" (AFH ch. 3). The reasoning is the AIH's simple-to-complex strategy: when teaching more than one skill at a time, start with the simplest so the learner gains confidence and is less likely to become frustrated (AIH ch. 9). Combine them once the student can hold a climb attitude without staring at the ASI.

Because an uncoordinated climbing turn adds drag that "counteracts the rate of climb, resulting in little or no altitude gain" — it is on the AFH's common-error list for this Task (ch. 3). Demonstrate it rather than assert it: stabilize a coordinated shallow climbing turn, note the VSI, then hold a bootful of inside rudder and let the student watch the vertical speed collapse while the pitch attitude has not moved. That single demo teaches coordination better than a chapter of explanation, and it is the honest answer to "why does the ball matter?"

Ten errors (AFH ch. 3), grouped by root cause:

Looking in the wrong place

• Establishing climb pitch by primarily referencing the airspeed indicator and chasing the airspeed.
• Fixating on the nose in straight climbs, so they climb with one wing low.

Feet

• Inadequate or inappropriate rudder during climbing turns.
• Allowing the airplane to yaw in the climb — usually not enough right rudder.
• Starting a climbing turn without coordinated controls, producing no turn and a wing-low climb.
• Improper coordination causing a slip that eats the climb rate.

Hands

• Applying elevator too aggressively, producing an excessive climb angle.
• Inability to hold pitch and bank constant during climbing turns.
• Excessive forward pressure during level-off, causing altitude loss or a low-G push.

Expectations

• Attempting to exceed the airplane's climb capability — the density-altitude conversation, early.

Analyze: the ASI lags, so every correction they make is a response to a condition that has already changed — they oscillate, and the oscillation grows.

Correct: move the reference. Cover the ASI, have them set the nose against the horizon at the pitch you demonstrated, hold it, count to five, then uncover and look. Their reaction is usually surprise that the speed settled itself. This is the integrated-instruction principle applied concretely — the natural horizon sets attitude, the instrument validates it — and the AFH notes that attitude by reference to the natural horizon "presents immediate and accurate indications many times larger than on any instrument" (AFH ch. 3).

Same order every time, in the sequence you explained on the ground (AIH ch. 9 — the demonstration should conform to the explanation and follow the same sequence to avoid confusion):

• "Clearing turn — I'm looking above and ahead, because we're about to put the nose where I can't see."
• "Pitch first: nose comes to here on the horizon. Power up to climb setting at the same time."
• "Feel that? The nose wants to keep coming up with the power — I'm holding it, not fighting it."
• "Right rudder. The airplane is trying to go left, and it will do that every climb you ever fly."
• "Wingtips — both level. Not the nose."
• "Speed is settling. Now I trim the pressure away."
• "Quick check inside: VSI positive, airspeed on the number, heading steady. One second. Back outside."
• "Level-off: 500 a minute, so I start 50 feet early. Nose comes down slowly, power stays up while we accelerate, then cruise power, then trim."

Collision hazards get materially worse, because a nose-high attitude hides the airspace you are climbing into. Teach the student that the clearing obligation does not end at the entry: clear before the climb, and keep the scan going by gently yawing or making shallow S-turns where the procedure permits, so the area ahead and above is actually seen. The AFH's standard is that you teach an effective clearing procedure and insist on its use before all turns and all training maneuvers (AFH ch. 1).

Distraction and task prioritization — the climb is high-workload: right rudder, throttle creeping, trim changing, and a level-off target approaching. That is the phase in which a student sheds the airplane to handle a task. Practice it deliberately with the AIH's sanctioned distractions, including "climb 200 feet and maintain altitude, then descend 200 feet and maintain altitude" (AIH ch. 9).

Loss of situational awareness and disorientation — R1 names these explicitly and applicants routinely skip them. The climb is where they bite:

• Somatogravic illusion. The acceleration of a climbing departure stimulates the otolith organs the same way tilting the head back does, creating the illusion of a nose-up attitude — and the disoriented pilot pushes into a nose-low or dive attitude, "especially in conditions with poor visual references." A quick throttle reduction does the reverse: the illusion pulls them nose-up toward a stall (PHAK ch. 17).
• Inversion illusion. An abrupt change from climb to straight-and-level — i.e., your level-off — can create the sensation of tumbling backwards, which the pilot answers by shoving the nose down (PHAK ch. 17). Brief the smooth, slow level-off partly for this reason.
• Feel is not attitude. Tie it back to Task VIII.A: sole reliance on the kinesthetic sense "ultimately leads to disorientation and loss of aircraft control" (AFH ch. 3). The natural horizon and the instruments arbitrate; the seat does not.
• Positional SA. A sustained nose-high attitude hides the horizon segment ahead and eats altitude fast. Require the student to say the altitude target and heading out loud before entering, so a lost level-off is caught by them, not by you.

Your limits — a full-power nose-high wing-low uncoordinated attitude is a stall/spin setup. Guard the controls, and take them with "I have the flight controls" rather than coaching a deteriorating attitude (AIH ch. 9).
