2.2 Before-Taxi Check

Once the engine starts and stabilizes at idle RPM (800 to 1000 RPM), you begin configuring flight instruments, avionics, and communication equipment before releasing the brakes.

Flight Instrument Setup and Verification

Perform the cockpit instrument check while the aircraft is completely stopped:

Sterile Cockpit Rule and Taxi Clearance

Keep non-essential conversation to a minimum (*Sterile Cockpit*) while listening to weather broadcasts, requesting taxi authorization from Tower, or announcing on CTAF. Never begin moving on the ground without reading back and understanding your assigned taxi route.

2.3 Taxiing & Wind Control Corrections

Taxiing is moving the aircraft on the ground surface under its own power. Precise ground handling prevents obstacle collisions, excessive brake wear, and runway incursions.

Speed and Directional Control

• Proper Speed: Taxi speed should be equivalent to a brisk walk (maximum 15 knots on open taxiways and walking pace in congested ramp areas). Control speed using the throttle lever (RPM), **NEVER** by riding the brakes continuously, which causes overheating and brake failure.

• Steering: Directional control is accomplished primarily using the rudder pedals connected to the steerable nosewheel, or through differential braking at low speeds.

Taxi Wind Correction Techniques (see image p. 2-11)

Wind creates lift and side forces on the wings and tail assembly (*weathercocking*). Correct flight control positioning during taxi prevents the wind from lifting a wing or the tail:

Runway Incursion Avoidance (see image p. 2-15)

• Hold Short Line: Marked by two solid and two dashed yellow lines. **NEVER** cross the first solid line without explicit ATC clearance.

• Full Stop Rule: If you need to check an airport diagram or read a complex checklist, bring the aircraft to a complete stop in a safe area off the taxiway before looking down.

2.4 Engine Run-Up

Perform the engine run-up in the designated holding bay before entering the active runway. The objective is to verify the dual ignition system, carburetor heat, and engine instrumentation at operational power.

Aircraft Positioning

Position the aircraft DIRECTLY INTO THE WIND. This ensures maximum cooling airflow through the engine cowling and prevents rear cylinder overheating while stationary.

Magneto System Check Sequence (see image p. 2-18)

1. Parking brake set and firm pedal pressure verified.
2. Smoothly advance the throttle to the RPM specified in the POH (e.g., 1700 RPM).
3. Magneto Check: Move the ignition switch from BOTH → RIGHT → BOTH → LEFT → BOTH.
   • Observe the RPM drop on each individual magneto.
   • AFH Standard Limit: Maximum allowable drop on a single magneto should not exceed 150 RPM, and the difference between left and right magnetos must not exceed 50 RPM.

Carburetor Heat Check

At run-up RPM, pull the **CARB HEAT knob to ON**: you should see an immediate slight drop in RPM (due to warmer, less dense air entering the engine). When pushed back to OFF, RPM should fully recover, confirming proper flap door operation.

2.5 Shutdown & Securing

A flight is only complete when the aircraft is safely parked, the engine is shut down with no leftover fuel in the lines, and the airframe is secured against wind gusts.

Engine Shutdown Procedure

1. Power Setting: Reduce throttle to idle/1000 RPM after final taxi.
2. Avionics Switch: Turn OFF the Avionics Master before shutting down the engine. This protects delicate radio circuits and screens from alternator voltage spikes.
3. Mixture Control: Pull the mixture control smoothly to IDLE CUT-OFF (fully aft). This starves the engine of fuel, ensuring a clean shutdown and preventing auto-ignition (*dieseling*).
4. Ignition and Master Switch: Once the propeller stops completely, turn the Magneto switch to OFF and remove the key. Turn OFF the Master Switch.

Securing the Aircraft on the Ramp (see image p. 2-22)

• Install the control lock on the yoke to secure ailerons and elevator.
• Place wheel chocks on main gear tires and release the parking brake.
• Install the Pitot tube cover and secure the aircraft using 3-point tiedowns (wings and tail).

3.2 Straight-and-Level Flight

Straight-and-level flight means maintaining a constant heading and constant altitude. It requires maintaining a proper visual relationship between the aircraft nose/wings and the natural horizon.

Pitch and Bank Integration

• Pitch Control: Adjusted using the elevator to maintain altitude. Small pitch corrections prevent altitude drift.
• Bank Control: Maintained using ailerons to keep the wingtips equidistant from the natural horizon.
• Power Integration: Cruising airspeed is established by setting cruise power (RPM) and trimming the elevator once stabilized.

3.3 Climbs & Climbing Turns

A climb is initiated by applying back-elevator pressure to raise the pitch attitude while simultaneously adding engine power to climb RPM. As power increases, left-turning tendencies become pronounced.

Airspeed Categories for Climbs

• Best Angle of Climb (Vx): Yields the greatest altitude gain in a given distance. Used for short-field obstacle clearance.
• Best Rate of Climb (Vy): Yields the greatest altitude gain in a given time. Used for normal climb-outs after clearing obstacles.
• Cruise Climb: Higher airspeed providing better forward visibility and engine cooling.

Leveling Off from a Climb

To level off, lead the target altitude by approximately 10% of your climb rate (e.g., if climbing at 500 fpm, begin leveling off 50 feet below target). Lower the pitch attitude to level, allow airspeed to accelerate to cruise, then reduce power to cruise RPM and trim.

3.4 Descents & Descending Turns

A descent is established by reducing power and adjusting pitch attitude to maintain the desired descent rate and airspeed. Descents can be executed with partial power or at idle (glides).

Leveling Off from a Descent

To level off from a descent to cruising altitude, apply power to cruise setting BEFORE raising the pitch attitude (typically 50 feet prior to target altitude), then adjust pitch to level flight attitude and re-trim.

3.5 Turns & Coordinated Flight

A turn is executed by banking the wings using ailerons, creating a horizontal component of lift that pulls the aircraft around the turn. The rudder is used solely to coordinate the entry and recovery, eliminating adverse yaw.

Understanding Turn Dynamics

• Adverse Yaw: When entering a bank, the raised wing creates more lift and more induced drag, pulling the nose toward the outside of the turn. Simultaneous rudder input in the direction of the turn cancels adverse yaw.
• Overbanking Tendency: In steep turns (greater than 45° bank), the outside wing travels faster than the inside wing, causing the bank angle to increase automatically unless neutral or opposite aileron pressure is applied.

3.6 Integrated Scanning & Visual Reference System

Integrated flight instruction teaches student pilots to control the aircraft by outside visual references while continuously cross-checking performance on flight instruments inside the cockpit.

Instrument Fixation Error

A common error among student pilots is staring at cockpit instruments (instrument fixation). Pitch and bank must always be set by looking outside at the horizon; instruments only confirm if the established attitude is achieving desired performance.

3.7 Slow Flight (Minimum Controllability Airspeed)

Slow flight is maneuvering at airspeeds where any further increase in angle of attack, increase in load factor, or reduction in power will result in an immediate stall horn or stall entry. It builds essential pilot feel for low-speed handling during approaches and landings.

Establishing Slow Flight ($V_S + 5$ to $10\text{ knots}$)

1. Clear the area with 360-degree clearing turns before entry. (see image p. 3-25)
2. Reduce power smoothly to entry setting while applying back-elevator pressure to hold altitude as airspeed bleeds off.
3. Extend flaps incrementally as airspeed drops below $V_{FE}$ (maximum flap extended speed).
4. As target airspeed ($V_S + 5$ to $10\text{ knots}$) is reached, increase power to maintain altitude at high pitch attitude.

Recovery from Slow Flight

To recover, advance the throttle smoothly to FULL POWER while simultaneously applying forward elevator pressure to prevent climbing and maintain altitude. Retract flaps in steps as airspeed increases, and re-trim for cruise flight.

4.2 Role of Flight Controls in Energy Management

Understanding the primary and secondary roles of the flight controls allows pilots to prevent energy mismanagements such as unintended stalls or excessive airspeed descents.

Primary Control Roles

• Throttle (Power Lever): Primary controller of total aircraft energy state. Increasing power supplies energy to climb or accelerate; reducing power removes energy to descend or decelerate.
• Elevator (Pitch Control): Primary controller of energy distribution. Pushing forward converts potential energy (altitude) into kinetic energy (airspeed). Pulling back converts kinetic energy into potential energy.

4.3 Rules of Energy Control

Pilots must adhere to three fundamental rules of energy control to maintain safe margins during all phases of flight, particularly during approaches and low-speed maneuvering.

Visualizing Energy Boundaries

Every aircraft has distinct structural and aerodynamic energy boundaries. Exceeding the upper boundary risks structural damage (VNE), while dropping below the lower energy boundary causes aerodynamic stall (VS).

4.4 Mitigating Energy Mismanagement Risks

Failure to manage energy correctly leads to critical flight anomalies, including low-energy stalls, unstabilized approaches, or excessive runway floating during landing.

Two Common Energy Mismanagement Scenarios

Preventing Irreversible Deceleration & Sink Rate

When operating on the backside of the power curve (region of reversed command), increasing pitch to maintain altitude without adding power increases induced drag drastically, creating an irreversible sink rate.

4.5 Terms & Definitions

A quick reference of essential energy management terms utilized throughout the FAA Airman Certification Standards (ACS).

5.2 Stall Recognition & Recovery

Timely stall recognition and correct, instinctual recovery inputs are critical to prevent loss of control in flight (LOC-I), especially when operating near the ground during takeoff or landing.

Sensory Cues for Impending Stall

Pilots must rely on integrated visual, auditory, and tactile cues to recognize an oncoming stall before the wing fully breaks:

Standardized Stall Recovery Template

The primary goal during any stall recovery is to immediately reduce the angle of attack below the critical threshold while maintaining directional control.

1. Decrease Angle of Attack: Promptly and smoothly push the control wheel/stick forward to lower the pitch attitude until the stall warning ceases and smooth airflow is restored.
2. Roll Wings Level: Apply coordinated aileron and rudder inputs to level the wings simultaneously.
3. Apply Power: Advance the throttle smoothly to maximum available power to minimize altitude loss.
4. Adjust Aircraft Configuration: Retract flaps and landing gear incrementally per POH recommendations once a positive rate of climb is established.
5. Return to Desired Flight Path: Smoothly ease back on the pitch control to re-establish normal climb or level flight attitude.

5.3 Types of Stalls

Flight training covers specific stall maneuvers to familiarize student pilots with flight characteristics across different flight phases and configurations.

Power-Off (Approach and Landing) Stalls

Simulates an impending stall during the final approach or landing flare. Performed with power set to idle or approach power, flaps extended, and landing gear deployed (see image p. 5-10). The goal is to recognize the stall and recover with minimal altitude loss.

Power-On (Takeoff and Departure) Stalls

Simulates an accidental stall during takeoff, initial climb-out, or go-around. Performed in takeoff configuration (flaps/gear per POH) at climb power (typically 65% or higher) (see image p. 5-13). Characterized by high nose attitudes and pronounced left-turning tendencies requiring strong right-rudder pressure.

5.4 Spin Dynamics & Phases

A spin is an aggravated stall that results in a continuous autorotation of the aircraft around a steep, helical downward path. An aircraft MUST be stalled and uncoordinated to enter a spin.

Four Distinct Phases of a Spin

5.5 Spin Recovery & Procedures

Spin recovery must follow a standardized, memory-item sequence. Always follow the specific procedures in the POH/AFM for your aircraft; in the absence of specific manufacturer procedures, use the standard FAA spin recovery procedure (PARE).

Post-Recovery Actions

Once rotation stops, neutralize the rudder immediately, smoothly pull back on the pitch control to recover from the dive without exceeding structural load limits (g-limits or VNE), and re-establish power.

6.2 Rectangular Course

The rectangular course maneuver simulates the flight path flown in an airport traffic pattern. The aircraft flies a square or rectangular path at a constant distance (typically 1/4 to 1/2 mile) around a selected field bounded by distinct roads or boundaries.

Leg-by-Leg Wind Drift Corrections (see image p. 6-5)

1. Upwind Leg: Heading matches ground track. Groundspeed is slowest. Bank angle for turn to crosswind starts shallow and gradually increases.
2. Crosswind Leg: Wind blows from the side. Pilot must crab into the wind. Ground track remains perpendicular to boundaries.
3. Downwind Leg: Heading matches ground track. Groundspeed is highest. Bank angle for turn to base/crosswind starts steep and gradually shallowing out.
4. Base/Final Leg Equivalent: Aircraft crabs into the crosswind component while maintaining a uniform distance from the field boundary.

6.3 S-Turns Across a Road

S-Turns across a road consist of flying a series of alternating 180-degree semicircles of equal radius on opposite sides of a straight ground reference line (such as a straight road or fence line) perpendicular to the wind direction.

Execution and Bank Variations (see image p. 6-8)

• Road Crossing (Upwind/Downwind Entry): Crossing the road must occur with wings completely level and perpendicular to the road line.
• Downwind Semicircle Entry: High initial groundspeed requires an immediate steep bank angle, which is progressively reduced to shallow as the aircraft turns into the wind.
• Upwind Semicircle Entry: Low initial groundspeed requires an immediate shallow bank angle, which is progressively increased to steep as the aircraft turns downwind.

6.4 Turns Around a Point

Turns Around a Point require the aircraft to fly a precise 360-degree circular path of constant radius around a single, small ground reference point (such as a solitary tree, water tower, or intersection).

Bank Angle Profile During 360° Turn (see image p. 6-11)

Distance and Altitude Standards

The pilot maintains a constant distance from the reference point (typically 1/4 to 1/2 mile) and holds altitude within ±100 feet while maintaining airspeed within ±10 knots per ACS standards.

6.5 Elementary Eights

Elementary eights are introductory training maneuvers that combine turns in opposite directions around or along ground reference points to refine control coordination and wind drift orientation.

Types of Elementary Eights

• Eights Along a Road: Two 360-degree loops flown on either side of a straight road, crossing the road diagonally or perpendicularly at the intersection point.
• Eights Across a Road: Similar to S-turns, but forming full 360-degree loops that intersect across a central reference line.
• Eights Around Pylons: Flown around two distinct reference points (pylons) separated by a specified distance, requiring precise bank adjustment to maintain symmetrical loops around both points (see image p. 6-15).

7.2 Entry & Departure Procedures

Proper entry and departure paths minimize collision risks between arriving, departing, and pattern traffic.

Standard Pattern Entry Method (see image p. 7-5)

The FAA recommended entry to a standard pattern is at a 45-degree angle toward the midpoint of the downwind leg at Traffic Pattern Altitude. This provides excellent visibility of downwind traffic and allows smooth merging.

7.3 Wind Drift & Pattern Management

Wind drift correction is essential to maintain a rectangular track around the runway and prevent crowding the downwind leg or overshooting final approach.

Base-to-Final Turn Overshoot Risk

A strong tailwind on downwind increases groundspeed, driving the aircraft rapidly past the base-to-final turn point. Uncoordinated rudder input to force the turn causes a dangerous skidding turn, creating prime conditions for a cross-control stall or spin.

7.4 Towered vs. Non-Towered Fields

Communication protocol and operational responsibilities depend heavily on whether the airfield operates with an active Control Tower (Class B/C/D) or as a non-towered field (Class E/G).

7.5 Traffic Safety & Visual Illusions

Managing separation and avoiding visual illusions during approach ensures safe, stabilized landings.

Wake Turbulence & Runway Incursions

Maintain separation behind heavy aircraft by staying on or above their glidepath and touching down past their rotation point. Always verify runway alignment visually before crossing hold short lines.

8.2 Go-Around / Rejected Landing

A go-around (rejected landing) is a planned maneuver executed whenever a safe landing cannot be completed. Making a prompt, decisive go-around decision is a primary hallmark of sound pilot judgment.

Preventing Elevator Trim Stalls During Go-Around

When full power is applied during a go-around with heavy nose-up elevator trim set (from final approach), the aircraft exhibits a powerful, immediate pitch-up tendency. The pilot must apply strong FORWARD ELEVATOR PRESSURE to prevent a high pitch angle stall while re-trimming.

8.3 Crosswind & Turbulent Air Techniques

Crosswind approaches require counteracting lateral wind drift so that the aircraft’s longitudinal axis remains aligned with the runway centerline throughout approach, flare, and rollout.

Crab Method vs. Sideslip Method (see image p. 8-10)

Touchdown in Crosswind Conditions

Touch down on the UPWIND MAIN WHEEL FIRST, followed by the downwind main wheel, and finally the nosewheel. As airspeed decreases during rollout, continuously increase aileron deflection fully INTO the wind to prevent the upwind wing from lifting.

Turbulent Air & Gust Factor Corrections

In gusty conditions, increase target approach speed by adding HALF THE GUST FACTOR to normal VREF (e.g., if wind is 10 knots gusting to 20 knots, gust factor is 10 knots; add 5 knots to VREF). Use partial flaps to maintain positive control authority.

8.4 Short-Field & Soft-Field Landings

Performance landings require specialized approach angles, speed control, and touchdown techniques based on runway length and surface conditions.

Short-Field Approach and Landing (see image p. 8-16)

Executed when landing over obstacles or on limited runway length:

1. Establish a steep descent path with full flaps extended at precise minimum approach speed (1.3 VSO).
2. Maintain precise power-to-pitch coordination to hit the designated touchdown point.
3. Reduce power to IDLE immediately upon touchdown, retract flaps to transfer weight to main wheels, and apply maximum effective braking without skidding tires.

Soft-Field Approach and Landing (see image p. 8-19)

Executed on unprepared, soft surfaces (grass, gravel, mud) to prevent nosewheel sinking:

8.5 Faulty Landings & Corrective Actions

Recognizing landing errors during the flare allows pilots to take immediate corrective action or execute a go-around before structural damage occurs.

Common Landing Anomalies & Diagnostics

9.2 Steep Spirals

A steep spiral is a gliding performance maneuver flown in a continuous descending turn around a fixed point on the ground. The objective is to maintain a constant radius around the point while executing three complete 360-degree turns while correcting for wind drift.

Engine Clearing and Safety

Because the engine operates at IDLE power throughout a prolonged descent, the pilot must clear the engine periodically by advancing the throttle smoothly to cruise power to prevent spark plug fouling and carburetor icing.

9.3 Chandelles

A Chandelle is a maximum performance 180-degree climbing turn that begins at cruise speed and finishes near minimum controllable airspeed (VS1). It demonstrates maximum climb capability for a given power setting.

Two-Phase Execution Breakdown (see image p. 9-8)

9.4 Lazy Eights

A Lazy Eight is an advanced coordination maneuver consisting of two symmetric 180-degree turns in opposite directions, forming a figure-eight pattern on the horizon. Pitch, bank, airspeed, and altitude are constantly changing throughout the maneuver.

Key Reference Points Across Each 180° Loop (see image p. 9-12)

10.2 Night Illusions & Spatial Disorientation

The lack of a visible horizon creates optical and vestibular illusions that can rapidly cause spatial disorientation if the pilot does not rely on flight instruments.

Common Night Flight Illusions (see image p. 10-6)

Overcoming Spatial Disorientation

When visual horizon cues are obscured or misleading, the pilot must disregard somatic bodily sensations and trust the instrument cross-check explicitly.

10.3 Aircraft Equipment & Airport Lighting

Operating safely at night requires specialized aircraft lighting systems and airport illumination infrastructure.

VFR Night Equipment Requirements (14 CFR 91.205)

For night VFR flight, standard daytime instrument requirements (ATOMATOFLAMES) must be supplemented with FLAPS equipment: Fuses (spares), Landing light (if for hire), Anti-collision lights, Position lights, and Source of electrical power.

Airport Lighting & Visual Approach Indicators

10.4 Preflight, Taxi & En Route Navigation

Night operations demand thorough preflight planning and heightened vigilance during ground movement and en-route navigation.

Night Preflight Inspection & Cockpit Preparation

Inspect all external lights, pitot heat, and windshield cleanliness thoroughly. Keep a reliable flashlight with fresh spare batteries accessible in the cockpit at all times.

Taxi Operations & En Route Safety

10.5 Night Approaches, Landings & Emergencies

Executing approaches and managing emergencies at night requires disciplined pitch-and-power flying and precise runway lighting alignment.

Night Approach and Flare Technique (see image p. 10-18)

Maintain a stabilized approach using VASI/PAPI indicators or instrument cross-checks to avoid landing short. During the flare, judge height above the runway using peripheral vision scanning of runway edge lights; avoid staring directly into the landing light beam.
