📖 1. Cabin Crew Training Courses

📝 Essential Points

• The necessary training consists of:
  • the Cabin C.A. licence
  • the Operation Conversion Course (OCC)
  • the Aircraft Type Conversion Course (ATCC)

📌 The CCH and OCC differ through the areas of safety, security, and communication, while the broader cabin crew training also includes service and aircraft type knowledge for a maximum of three aircraft types.

CA–OCC–ATCC: licence, conversion, aircraft type

📖 2. Flight Deck and Cabin Hierarchy

★ Must-know

• The captain has overall responsibility on the flight deck.

• The first officer:

  • takes direct orders from the captain
  • supports the captain in maintaining safety
  • acts as the captain's main assistant
  • assists in evacuation

• The purser, also called the SCCM or Senior Cabin Crew Member, is the cabin manager who reports directly to the captain, coordinates flight preparations, and coordinates and leads normal and emergency procedures.

Further detail

• The second officer, also called the co-co, is below the first officer in the flight deck chain of command.

💡 Memory Hook

Captain → First officer → Second officer; Purser → cabin crew

📖 3. Cabin Crew Staffing Requirements

📝 Essential Points

📌 The minimum required cabin crew staffing level is one cabin crew member per 50 passenger seats.

• The regulatory standard requires one cabin crew member for 19–50 seats and two cabin crew members for 51–100 seats.

💡 Memory Hook

More passenger seats → more required cabin crew

📖 4. Aviation Regulatory Organizations

🔑 Key Concepts & Definitions

• International Civil Aviation Organization : creates global aviation rules through standards and recommendations
• European Union Aviation Safety Agency : applies and adapts ICAO rules for European Union countries and ensures uniform safety and environmental standards
• Civil Aviation Authority : regulates and oversees civil aviation nationally and enforces the global safety and navigation standards established by ICAO

📝 Essential Points

• ICAO was founded in 1944 at the Chicago Convention, is headquartered in Montreal, and has 19 annexes.

• Operators such as airlines and airports create internal procedures and policies, which are highlighted in the company's Operation Manual.

• The International Air Transport Association (IATA) is a supportive organization founded in 1945 in Havana, headquartered in Montreal and Geneva, representing 370 airlines worldwide and focusing on economic and commercial air transport standards.

💡 Memory Hook

ICAO global rules → EASA EU application → CAA national enforcement → operator procedures

📖 5. Aviation Units and Time Standards

🔑 Key Concepts & Definitions

• UTC : or Universal Time Coordinated, is the single time standard used in aviation because the Earth is divided into 24 time zones and using one time avoids confusion in flights, schedules, and operations

★ Must-know

• Typical aviation terminology uses:

  • feet for heights
  • the NATO alphabet for letters
  • UTC for time

• One foot equals 30.48 cm, and three feet are approximately one metre.

📌 To convert a height from feet to metres, divide by three; the course gives 30,000 ft = 10,000 m, 27,000 ft = 9,000 m, 24,000 ft = 8,000 m, 21,000 ft = 7,000 m, 18,000 ft = 6,000 m, and 15,000 ft = 5,000 m.

Further detail

• The NATO alphabet is a standardized set of words used to clarify letters; it was adopted globally in 1956, finalized by ICAO, and adopted by NATO.

💡 Memory Hook

Feet measure height, whereas UTC standardizes operational time

📖 6. Operational Abbreviations and Crew Challenges

★ Must-know

• The course lists these operational abbreviations:

  • UM for Unaccompanied Minor
  • DEPU for Deportee Unaccompanied
  • DEPA for Deportee Accompanied
  • INAD for Inadmissible
  • PRM for Passenger Reduced Mobility
  • APU for Auxiliary Power Unit
  • GPU for Ground Power Unit
  • ALTN for alternate airport for landing
  • ETA for Estimated Time of Arrival
  • LMC for Last Minute Change

• Common cabin crew difficulties include:

  • mental stress
  • physical discomfort
  • fatigue
  • social life difficulties
  • cultural diversity

• Pressurized cabins cause body gases to expand by 30% and can produce ear and sinus pressure because of pressure changes.

• Reasons for fatigue include: sleep loss from insufficient deep sleep, circadian-rhythm disruption from flying through different time zones, long working hours

Further detail

• The wheelchair codes are:

  • WCHR for Wheelchair Ramp
  • WCHS for Wheelchair Stairs
  • WCHC for Wheelchair Complete

• Reasons for mental stress include:

  • high workload
  • unruly passengers
  • unexpected situations
  • long duty hours
  • safety responsibilities
  • constant vigilance

• Assisting passengers by lifting bags and trolleys can cause back and leg pain.
