Discuss (a) the operator's test

The problem (the third-party damage): the aircraft's crash-or-incident harming the persons- and-property on the ground — the surface's victims: not the passengers (the carriers' liability of Unit 4 handles them) but the neighbours of flight — the falling aircraft, the shed parts, the crash's fire. The Rome 1952's regime: The liable person: the operator (the aircraft's user at the incident's time — not the owner- as-such, not the carrier's contractual face: the operational test); The liability's standard: the absolute liability (strict) for the damage — no fault's proof needed; the damage's proof suffices (the risk's logic: the aircraft's operator profits from the risk-laden activity — the risk's cost internalised); The caps (the limits): the liability limited by the aircraft's weight (the maximum-take-off- mass scale — the heavier the aircraft, the higher the cap: the risk's rough proxy); the caps' levels per the weight bands (the treaty's own schedule; the low-limit criticism's history); The defences (the narrow set): the damage caused by the person's-own fault; the armed- conflict faces; the contributory negligence's reduction; the otherwise-inevitable-event faces (the narrow exclusions — the strict regime's character); The jurisdiction-and-enforcement: the damage's-place courts; the compulsory insurance (the operator's cover duty — the victim's security: the insurance-and-guarantee machinery; the certificates' display); The 1978 Montreal Protocol's modernisation: the caps' raise (the inflation-and-the- insurance-world's answer); the low-ratification fate…
