First, we have Contaminated Runway, which you'll find on page 233 — Page 267, Lesson 368

I want to walk you through the index of this Operational Procedures manual. This is your map to the entire book, so let's look at the entries that start with the letter C and then D. First, we have Contaminated Runway, which you'll find on page 233. This is a specific runway condition that affects takeoff and landing performance, and we'll cover it in detail later. Next is Contingency Fuel, referenced on pages 26 and 42. This is the extra fuel you carry beyond your planned requirements, to handle unexpected situations like holding or diversions. Then we have Continuous Descent Final Approach, abbreviated as CDFA, on pages 54 and 56. This is a technique where you maintain a steady descent all the way to the runway threshold, rather than leveling off at different stages — it improves efficiency and reduces noise. Controlled Airspace, or CAS, appears on pages 35 and 120. This is airspace where air traffic control provides separation services to all aircraft — you need clearance to enter it. Co-Pilot is listed on page 94. That's the second-in-command pilot, who assists the captain and is fully qualified to operate the aircraft. CPDLC stands for Controller-Pilot Data Link Communications, found on pages 133 and 135. This is a digital text-messaging system between pilots and air traffic control, used as an alternative to voice radio. CPL (A) means Commercial Pilot Licence (Aeroplane), on pages 93 and 94. That's the licence you need to fly for hire or reward. Crash Axes and Crowbars are both listed on pages 86 and 164. These are emergency tools carried on board — the crash axe is for cutting through aircraft structure to escape, and crowbars are for prying open doors or panels. Crew Composition on page 93 refers to the minimum number and qualifications of crew members required for a flight. Crew Resource Management, or CRM, is on page 93 — that's the effective use of all available resources, including people, equipment, and information, to ensure safe flight operations. Crew Training Manager on page 24 is the person responsible for overseeing the training programs for all crew members. Critical Phases of Flight are on pages 26, 35, and 45. These are the most safety-sensitive parts of a flight — typically takeoff, initial climb, final approach, and landing — where distractions are minimized. Critical Power Unit on page 80 is a term used in multi-engine aircraft: it's the engine whose failure would have the most adverse effect on performance and handling. CRM appears again on pages 95, 96, 97, 100, and 101 — that's the same Crew Resource Management concept, now with more detailed coverage. Cumulative Duty Hours on page 106 refers to the total hours a crew member has worked over a given period, which is regulated to prevent fatigue. CVRs stands for Cockpit Voice Recorders, on page 75. These are the devices that continuously record all sounds and conversations in the cockpit for accident investigation. Moving to the D section, we start with Damp Runway on page 233 — that's a runway that's wet but not enough to be considered contaminated, and it affects braking action. Dangerous Goods are covered on pages 104, 105, and 219. These are items that pose a risk to health, safety, property, or the environment when transported by air. Dangerous Goods Accident on page 219 is an occurrence involving dangerous goods that results in injury, damage, or hazard. Dangerous Goods Incident on pages 47 and 219 is a less severe event — something related to dangerous goods that doesn't meet the definition of an accident but still needs to be reported. Data Link on page 134 is the general term for digital communication systems between aircraft and ground stations. Decision Height on page 64 is a critical altitude during an instrument approach — it's the height at which you must decide whether to continue the approach and land, or execute a missed approach. De-fuelling on page 45 is the process of removing fuel from the aircraft's tanks, which has its own safety procedures. De-icing on pages 146, 147, and 148 is the removal of ice, snow, or frost from the aircraft surfaces before flight. Deportee on page 43 refers to a passenger being forcibly removed from a country, which has specific handling procedures. Designated Duty Station on page 45 is the specific seat or position a crew member is assigned to during a flight. Destination on pages 36 and 107 is the airport where the flight is scheduled to land. And finally, Destination Alternate on pages 4 and 3 — that's an alternate airport you plan to divert to if you cannot land at your destination for any reason. These are the key terms from the C and D sections of your index. Each one points to a specific topic we'll study in detail as we go through the book.
