15 PERCENT OPERATIONAL EXTENSION
To enhance operational flexibility, the ETOPS rules published in the mid-1980s allowed for 120-min operations with the possibility of a 15 percent operational extension. When the rules were revised to include 180-min ETOPS, a similar provision permitting a 15 percent operational extension on 180 min was not included. The aviation industry is seeking a 15 percent operational extension on the 180-min rule to permit operators (and the pilot in command) further flexibility in selecting the most optimum en route alternate airports.

REVIEW OF REQUIREMENTS
Using ETOPS has become a standard for many operators, and several European operators have requested the Joint Aviation Authorities ETOPS Working Group to consider revisiting the ETOPS requirements. Their intent is to retain those elements that add value to their ETOPS operations and delete what they consider unnecessary restrictions on two-engine-airplane operations.
