Even with Boeing in the news these days, the planes involved in their new $16.6 billion deal with Iran Air, the first of which are scheduled for delivery in 2018, have gotten less attention. Today, let’s take a look at those planes.

According to Boeing’s press release, each of the models involved in the contract have featured improvements, including the 737 MAX 8’s Advanced Technology winglets and the 777-9X’s composite high-span wings and flight area touch screens.
Boeing’s 737 MAX 8, which is scheduled to enter service in 2017, features what Boeing calls Advanced Technology (AT) winglets, or “the most efficient winglet on any airplane.” Boeing devotes a page of its website to convince buyers of this (you should check it out). The bottom line is that “in addition to the inward, upward, and slightly forward lift components of the upper aerofoil,” which is relatively common on planes these days, “the new lower aerofoil generates a vertical lift component that is vectored away from the fuselage, and also slightly forward” to perfectly balance the winglet. These winglets also reportedly reduce the fuel consumption of the 737 MAX by 1.8%.
The composite high-span wings, a key feature in Boeing’s new line of 777X planes (which includes the 777-9X), will be fabricated at Boeing’s brand-new 1.3 million sq ft Composite Wing Center (CWC) in Everett, WA. These wings, crafted from “a super light and strong carbon fiber composite material” were called “the most phenomenal wings in the world” by Boeing’s CEO Ray Conner, but they’re also the longest wings Boeing has ever built. As of December 6, the CWC was not fully complete, but preproduction for the 777X was underway. This video shows you the first prototype wing panel for the 777X, which is 105 ft long!
In comparison, adding touch screens in the flight area may seem slightly less impressive, but Mike Carriker, Chief Pilot for Airplane Development with Boeing Test & Evaluation, says adding these touch screens makes the equipment “easier for the flight crew to use” because “everyone knows how to use a touch screen.” Boeing’s primary goal with this introduction is to decrease the time spent on retraining pilots to use the 777X when it debuts. In addition, “it makes data selection easier, and it removes parts from the airplane.”
How do you feel about these updates? Are you excited to see these planes take off in the next few years?
