Technical Standards for Private Pilot ACS Emergency Operations (FAA-S-ACS-6C)

The transition to the Airman Certification Standards (ACS) represented a shift toward integrated evaluation, where knowledge and risk management are tested alongside flight proficiency. For the Private Pilot-Airplane certificate, Area of Operation IX: Emergency Operations, remains one of the most critical segments of the practical test. The current standard, FAA-S-ACS-6C, dictates the specific objectives and performance metrics an applicant must meet to demonstrate competency in handling abnormal and emergency flight conditions.

This technical guide outlines the standards for Tasks A through D within Area of Operation IX, adhering to the instructional guidance found in the FAA Airplane Flying Handbook (AFH).

Structural Framework of Emergency Operations

Each task within the ACS is categorized into three distinct elements: Knowledge (K), Risk Management (R), and Skills (S). During the practical test, an evaluator assesses the applicant’s ability to synchronize these elements. In an emergency, technical proficiency is insufficient if the pilot fails to manage the risks of denial or indecision. Conversely, correct risk assessment is negated by an inability to maintain the stabilized glide or airspeed tolerances defined in the standards.

Task A: Emergency Descent

Task A evaluates the pilot's ability to transition the aircraft from cruise flight to a high-rate descent safely and efficiently. This maneuver is typically prompted by scenarios such as an in-flight fire, smoke in the cockpit, or a rapid loss of cabin pressure.

Knowledge and Risk Management

The applicant must identify situations requiring an emergency descent and understand the specific procedures outlined in the Pilot’s Operating Handbook (POH) or Airplane Flight Manual (AFM). Key risk factors include the potential for structural damage if airspeed limits are exceeded and the hazard of task saturation during a high-stress event.

Skills and Execution

To meet the technical standard, the applicant must:

1. Identify the Emergency: Promptly recognize the need for descent.

2. Configuration: Configure the aircraft according to the POH/AFM. This often includes reducing power to idle and extending landing gear or flaps if permitted by the manufacturer's operating speeds.

3. Bank and Pitch: Establish the descent. The ACS specifies maintaining a bank angle between 30 and 45 degrees to maintain positive load factors and to provide the pilot with better visibility of the area below.

4. Airspeed Control: Maintain the appropriate airspeed as recommended by the manufacturer. If no speed is specified, the pilot should use the highest speed allowable for the current configuration (Vle, Vfe, or Vno/Vne as applicable). The tolerance is -10/+0 knots.

5. Engine Care: In air-cooled engines, the pilot must "clear" the engine periodically (once per revolution or as appropriate) to prevent spark plug fouling or excessive cooling, provided the emergency (e.g., fire) does not prohibit engine use.

6. Recovery: Execute a level-off at a specific altitude, as assigned by the evaluator, within +/- 100 feet.

Task B: Emergency Approach and Landing (Simulated)

This task focuses on the "Forced Landing" scenario where power is lost. The ACS emphasizes the pilot's ability to manage the aircraft's energy profile to reach a suitable landing area.

Distinguishing Forced vs. Precautionary Landings

Instructional guidance from AFH Chapter 18 distinguishes between these two scenarios. A forced landing is an immediate necessity due to engine failure or a major mechanical malfunction. A precautionary landing is a premeditated landing, usually with power available, due to deteriorating weather, fuel low-state, or minor system issues. Task B specifically tests the forced landing skills.

Skills and Execution

The performance standards for the simulated emergency landing are precise:

• Airspeed Management: Establish and maintain the best glide speed (Vg) as specified in the POH/AFM, with a tolerance of +/- 10 knots.

• Site Selection: Select a suitable landing area based on wind direction, terrain, obstacles, and distance.

• Flight Pattern: Plan and execute a flight pattern to the selected landing area. This involves reaching a "Key Position" (high key/low key) to ensure the landing is made within the first one-third of the available landing area.

• Checklists: Correctly use the emergency checklist to attempt an engine restart or prepare the cabin for touchdown (e.g., fuel selector off, master switch off, doors unlatched).

• Communications: Simulate or perform emergency radio calls (Mayday/Pan-Pan) and transponder squawking (7700).

The maneuver is typically terminated by the evaluator at an altitude sufficient for a safe go-around, usually no lower than 500 feet AGL unless over a designated runway.

Task C: Systems and Equipment Malfunctions

Task C evaluates the applicant's ability to diagnose and mitigate malfunctions that do not necessarily require an immediate landing but do require corrective action to maintain flight safety.

Knowledge Requirements

The applicant must demonstrate an understanding of the aircraft's systems, including:

• Powerplant: Partial power loss, oil pressure issues, and induction icing.

• Electrical: Alternator failure, battery depletion, and circuit breaker management.

• Avionics: Failure of primary flight displays (PFD), multi-function displays (MFD), or integrated flight decks.

• Pitot-Static: Blockages affecting the airspeed indicator, altimeter, or vertical speed indicator.

Risk Management and Skills

A primary risk in system malfunctions is "fixation." Pilots often focus on troubleshooting a minor system failure to the detriment of basic aircraft control. The ACS requires the pilot to prioritize the "Aviate, Navigate, Communicate" hierarchy.

Standardized performance includes:

1. Detection: Identifying the specific malfunction through instrument cross-checks or physical cues.

2. Checklist Usage: Utilizing the POH/AFM abnormal procedures checklist. Memory items must be performed first, followed by the published checklist.

3. Decision Making: Determining the appropriate course of action, such as continuing to the destination, diverting, or declaring an emergency.

Task D: Emergency Equipment and Survival Gear

Recent updates in the FAA-S-ACS-6C standards have expanded Task D to include modern safety technologies.

Survival Gear and Equipment

Applicants must demonstrate knowledge of the survival gear appropriate for the flight environment (e.g., over-water, mountainous, or desert terrain). This includes the use of Emergency Locator Transmitters (ELTs), Personal Locator Beacons (PLBs), and fire extinguishers.

Advanced Safety Systems

The ACS now includes an emphasis on:

• Ballistic Parachute Systems (BPS): Knowledge of deployment envelopes, activation procedures, and post-deployment expectations.

• Auto-Land Systems: Understanding the triggers, override procedures, and operational limitations of emergency autonomous landing technologies.

If the aircraft used for the practical test is equipped with these systems, the applicant must demonstrate the skill to operate or manage them according to the manufacturer’s guidance.

Standardized Risk Management in Emergency Operations

A recurring theme across all emergency tasks is the management of psychological and physiological hazards. The ACS specifically targets:

• Denial: The refusal to accept that an emergency is occurring, leading to a delay in initiating emergency procedures.

• Indecision: Hesitation in choosing a landing site or a course of action, which consumes critical altitude and time.

• Speed Management: The tendency to allow airspeed to decay during the stress of an emergency landing, which increases the risk of a stall/spin.

Communication Standards

In any emergency, communication must follow a standardized protocol to ensure the best possible assistance from Air Traffic Control (ATC).

1. Distress (Mayday): Used when threatened by serious and/or imminent danger and requiring immediate assistance.

2. Urgency (Pan-Pan): Used when the safety of the aircraft or a person on board is a concern, but immediate assistance is not yet required.

3. Transponder: Selecting Code 7700 alerts all radar controllers in the vicinity of the emergency status.

Evaluation Criteria for Success

To successfully pass the Emergency Operations section of the Private Pilot practical test, the applicant must maintain control of the airplane at all times. This includes:

• Stabilized Glide: Achieving and holding the Vg speed within 10 knots.

• Checklist Discipline: Not relying solely on memory for complex procedures after initial immediate action items are completed.

• Situational Awareness: Maintaining an awareness of the aircraft's position relative to the landing site or nearest suitable airport.
