UPDATING ENHANCED FLIGHT PLAN VARIANTS

原文（中国語）

A method and system for updating a variant for a reference flight plan for an aircraft with a flight management system (FMS) has been developed. First, the reference flight plan is generated with the FMS. A clone of the reference flight plan is copied for analysis of potential changes to the reference flight plan. The clone of the reference flight plan is modified with any changes to the reference flight plan that occurred subsequent to copying the clone of the reference flight plan. The modified clone of the reference flight plan is then analyzed for incorporating potential changes to the reference flight plan.
