Airside

Means being on the ‘apron’ of an airport making contact with aircraft possible. A motor insurer might in some circumstances exclude all liability from accidents while the insured vehicle is airside. In contract works insurance where the site of the work is at an airport, insurers will take a more stringent view of the work than the same work landside (no contact with aircraft).

Airworthiness Warranty

It is implied in all aviation policies that aircraft are maintained to specified standards following procedures laid down by the aircraft manufacturers in conjunction with the relevant civil aviation authority. The airline must keep maintenance records. Aircraft and engine manufacturers also specify the parameters for an aircraft’s operation. If an airline breaches any of these requirements the policy may be invalidated.

Alarm system in operation

Policy may warrant that an approved alarm system be kept in operation. In De Maurier (Jewels) Ltd v. Bastion Insurance Co. Ltd and Coronet Insurance Co. Ltd (1967), a warranty in a jewellers’ ‘all risks’ insurance stated ‘alarms on road vehicles be kept in operation… Held: ‘in operation means the system must be switched on in circumstances where the user has reason to believe that switching it on makes it fully operative. It does not mean “fully operative”. If, because of an unknown fault, it fails to operate there will be no breach of warranty by the insured.
