Search and Rescue — Page 468, Lesson 624

Right, let's get into Search and Rescue. This is a new chapter, and it's all about the machinery that swings into action when an aircraft goes missing or is in trouble. We're starting with the absolute foundations: the definitions and the legal setup that makes search and rescue happen. First, the definitions. These are required knowledge, so I want you to hear them precisely. We have three phases that describe how bad a situation is, and they're all grouped under one umbrella term. The umbrella term is the Emergency phase. It's a generic term that means, depending on the situation, one of three specific phases: the uncertainty phase, the alert phase, or the distress phase. Let's take them in order of severity. The uncertainty phase is the mildest. It's a situation wherein uncertainty exists as to the safety of an aircraft and its occupants. So, we're not sure something's wrong, but we're not sure everything's fine either. There's doubt. Next is the alert phase. This is a step up. It's a situation wherein apprehension exists as to the safety of an aircraft and its occupants. So now we're not just uncertain, we're actually worried. There's a real concern for their safety. And the most serious is the distress phase. This is a situation wherein there is a reasonable certainty that an aircraft and its occupants are threatened by grave and imminent danger or require immediate assistance. So we're reasonably sure they're in serious, immediate danger, or they've already asked for help. That's the top of the scale. Now, here's a critical operational point about the emergency phase. When it's activated, the Air Traffic Services, the ATS, shall immediately notify the RCC. And RCC stands for Rescue Co-ordination Centre. We'll define that properly in a moment, but just hold onto that link: emergency phase activated, ATS immediately tells the RCC. Now, the other key players. The Operator is a person, organization or enterprise engaged in or offering to engage in an aircraft operation. So it's the entity running the flying, or planning to. The Pilot-in-command, the PIC, is the pilot responsible for the operation and safety of the aircraft during flight time. That's the person in charge of the aircraft and everyone on it. The Rescue Co-ordination Centre, the RCC, is a unit responsible for promoting efficient organization of the SAR service and for co-ordinating the conduct of SAR operations within a SAR region. So it's the nerve centre, the unit that organises and co-ordinates the search and rescue effort in its area. And SAR, by the way, is Search and Rescue. And finally, the State of Registry is simply the State on whose register the aircraft is entered. That's the country that the aircraft is registered in. Now, let's move from definitions to how the whole system is set up. This is about the establishment and provision of the SAR service. The basis of establishment is that Contracting States, so the countries that are party to the Chicago Convention, shall arrange for the establishment and provision of SAR services within their territories. And these services shall be provided on a 24 hour basis. No gaps. And crucially, when providing assistance to aircraft in distress and to survivors of aircraft accidents, they shall do so regardless of the nationality of such aircraft or survivors. So nationality is irrelevant. If you're in trouble in their territory, they help you. Next, the establishment of SAR regions. Contracting States shall delineate the SAR regions within which they will provide SAR service. And here's a key constraint: such regions shall not overlap. Each region is clearly defined and they don't overlap. And there's a practical guideline here: the boundaries of SAR regions should, in so far as is reasonably practicable, be coincident with the boundaries of corresponding flight information regions. So the SAR region boundary should line up with the FIR boundary wherever possible. That keeps things clean and coordinated. Then we have the establishment and designation of SAR service units. Each SAR region gets a rescue co-ordination centre, an RCC. Contracting States shall establish one in each SAR region. And they should establish rescue sub-centres whenever this would improve the efficiency of the SAR services. So sub-centres are optional, but they're there to make things work better. The organization of the SAR services is the responsibility of the RCC and any subcentres established. And there's one more piece here, about alerting posts. In areas where public telecommunications facilities would not permit persons observing an aircraft in emergency to notify the rescue co-ordination centre concerned directly and promptly, Contracting States should designate suitable units of public or private services as alerting posts. So if a member of the public sees an aircraft in trouble, but the phone network is too poor to call the RCC directly, the State designates certain public or private units to act as alerting posts. Those posts are the go-between, the people who can receive the report and pass it on to the RCC. So, to tie it all together: we have three escalating phases of emergency, the RCC is the co-ordinating hub, and the States are legally bound to set up this 24-hour service, with non-overlapping regions, and alerting posts where needed. That's the foundation of the whole SAR system.
