 In February 2013 Avolon published an analysis of, and investor guide to, the expected market impact of the transition to new generation Airbus (320Neo) and Boeing (737MAX) single aisle aircraft families.This was Avolon's second white paper on industry issues and considered how the transition from A320ceo/737NG aircraft to A320Neo/737MAX aircraft will influence the single aisle aircraft market over the rest of the decade and beyond.The Avolon paper found that the effect of the Neo and Max models on the value of their predecessors will be limited by the sheer number of current-generation craft in use today and the high portion of the global aircraft fleet approaching retirement.
