Introduction

August 29, 2019, ©. Leeham News: In last week’s article we went through the reasons for a longer range 787-10, a 787-10ER version (ER for Extended Range). We could conclude it would be an attractive aircraft for the market if it could get another 1,000nm in range.

We use our airliner performane model to analyze how this can be achieved and if Boeing would face large engineering challenges to get to this range.

Summary:

• The 787 program would benefit from a longer range 787-10 as described in our first article
• Now we analyze how to achieve the extra range and what trades will be necessary to convert the 787-10 to a 787-10ER.
