There are several standard aircraft liability policies in the London market. One such policy, AVN1C, has been replaced by AVN1D, which is simpler and more reader-friendly. The new policy creates more certainty by introducing new definitions and expanding old ones. Further, it adds new sections such as ‘Choice of Law and Jurisdiction’, a provision relating to theft of aircraft and extended the ‘Defence and Settlement’ conditions, thus affording a greater degree of control to the insurance market. Most importantly, AVN1D has been updated to echo the wording used in current standard airline policies and international conventions, and to take account of the industry’s developments.
