Topic Synopsis
This element equips the helicopter crewman with the skills to plan and execute concealed approaches and departures (CAD) in challenging terrain, conduct confined area reconnaissance and manoeuvring, manage sloping ground landings, and navigate safely under high tension wires. Emphasis is placed on effective crew resource management, precise verbal guidance to the pilot, and demonstrating sound airmanship to mitigate risks in undulating, confined, and hazardous environments.
Key Concepts & Core Principles
- Crew Resource Management (CRM): The effective use of all available resources, including human, equipment, and information, to ensure safe and efficient flight operations. This includes communication, teamwork, decision-making, and situational awareness.
- Helicopter Aerodynamics and Performance: Understanding the principles of lift, thrust, drag, and weight, as well as factors affecting helicopter performance such as density altitude, weight and balance, and power limitations.
- Mission Planning and Navigation: The process of planning a flight route, considering factors like weather, airspace restrictions, fuel requirements, and emergency procedures. Includes use of charts, GPS, and radio navigation aids.
- Safety Management Systems (SMS): A systematic approach to managing safety, including hazard identification, risk assessment, and mitigation strategies. Covers topics like human factors, accident prevention, and emergency response.
- Helicopter-Specific Operations: Procedures for confined area landings, sling loads, hoist operations, and formation flying. Emphasises the unique operational capabilities and limitations of helicopters.
Exam Tips & Revision Strategies
- During practical assessments, verbalise every step of your reconnaissance and decision-making process; this demonstrates a thorough understanding and helps the assessor follow your logic.
- When guiding the pilot in confined areas, use precise clock-face references and distance cues, and always confirm the pilot's acknowledgment before proceeding.
- In written or oral questioning, always link your actions to the principles of threat and error management and crew resource management, showing you prioritise safety over expediency.
- For simulated wire hazards, practice calling out wire height, crossing angle, and recommended clearances early, and be prepared to discuss emergency actions if a wire strike occurs.
Common Misconceptions & Mistakes to Avoid
- Failing to maintain a continuous scan for wires and obstacles, especially when focusing on directing the pilot during high workload phases.
- Providing ambiguous or late directional commands, leading to pilot hesitation or incorrect manoeuvring in confined spaces.
- Misjudging the landing site slope steepness or being unaware of aircraft limitations, resulting in excessive bank or tail rotor clearance issues.
- Overlooking the need for a go-around or abort point during concealed approaches when the landing site becomes unsuitable.
Examiner Marking Points
- Award credit for demonstrating the ability to produce a detailed concealed approach and departure plan, including consideration of wind, obstacles, escape routes, and crew coordination.
- Award credit for clearly and confidently directing the pilot during the approach, hover, and departure phases with standardised commands, maintaining obstacle clearance and situational awareness.
- Award credit for performing a systematic reconnaissance of a confined area, assessing size, surface, slope, obstacles, and approach/departure paths, and communicating findings effectively.
- Award credit for assisting the pilot during sloping ground operations by accurately identifying slope angle and aspect, guiding the aircraft to the correct touchdown attitude, and managing passenger/cargo safety.
- Award credit for proactively identifying and announcing high tension wire hazards, recommending safe flight paths, and maintaining a safe distance while assisting the pilot during wire crossing or under-wire flight.
