Boeing Flight Testing on 737 Max 7, Smallest Variant
Boeing Flight Testing on 737 Max 7, Smallest Variant. Boeing will begin the flight certification campaign for the 737 Max 7 which featured 138 seats after the third and smallest variant of the family of single-aisle renovated aircraft completed an inaugural flight of more than 3 hours last week.
The first flight of the CFM International Leap-1B aircraft followed a familiar pattern. The test pilots approached 250 and 25,000 feet in a wide circuit at the Boeing flight test center in Moses Lake, in the interior of Washington State, where the plane made a low approach, says the Boeing 737 main pilot.
Jim Webb The plane made a low approach at the Moses Lake airport, system checks and a restart of the engine during the flight, he says.
Boeing expects to deliver the first 737-7 in 2019, with the 737 Max 200 and 737 Max 10 in a period of two years.
So far, the impact of the 737-7 on the market has been much less than the 737-700 it replaces. That 126-seat plane entered service with Southwest Airlines in 1998, the first of 1,126 737-700 delivered to date.
Boeing does not divide the orders of the 737 Max family by variant, with one exception. The 737-10 appears on the public list with a delay of 416 orders, but there is no such total for the other variants.
The commercial interest in the 737-7 is visible only by the number of customers. The type has been ordered by Southwest, Westjet, Riuli, Jetlines, Air Lease Corp and an unidentified airline, says Boeing. Two versions of the Boeing Business Jet aircraft have also been sold.
The attractiveness of the type in the commercial market has been questioned, but Boeing maintains the order potential of the smallest member of the 737 Max family.
When asked to name the percentage of that segment of the market lost because of the improvement, Haber refused to provide a number.
However, Haber says a redesign announced two years ago for the 737-7 added two frames and 12 seats to the fuselage compared to the 737-700, making the 737-7 a candidate for an airline that wants a larger plane. .
The 737-7 is also designed with a unique set of performance advantages, says Haber. For example, it shares the same version of the Leap-1B engine as the 737-8, but is lighter and smaller.
That combination means that the 737-7 should offer better takeoff performance at high temperatures, says Haber. The 737-7 flight test team plans to travel to Daocheng, China, later this year to validate those performance assumptions.

"We complete the entire test profile," says Webb. The first flight of the 737-7 arrives 10 months after the entry into service of the 737 Max 8 and less than a week before the first delivery of the 737 Max 9.Boeing expects to deliver the first 737-7 in 2019, with the 737 Max 200 and 737 Max 10 in a period of two years.

Jeff Haber, regional director of product marketing at Boeing, points out the possible demand for replacement, with about 2,500 737-700 and Airbus A319 currently operating.When asked to name the percentage of that segment of the market lost because of the improvement, Haber refused to provide a number.
