ARLINGTON- Boeing has reached another major milestone in the certification program for the 737-10 by successfully completing extreme crosswind autoland testing.
The campaign demonstrates the aircraft’s ability to perform automatic landings in some of the most demanding wind conditions expected during airline operations.
Boeing conducted the certification campaign using the Boeing 737-10, while testing took place at Midland International Air and Space Port (MAF) in Midland, Texas.
The results will support certification work with the Federal Aviation Administration (FAA) for both the 737-10 and the 737-7 later in 2026.
Boeing 737-10 Certification Crosswind Testing
Boeing has completed another significant phase of the certification campaign for its largest 737 MAX variant by intentionally flying the 737-10 into some of the strongest crosswinds airline pilots are expected to encounter during normal operations.
Unlike many certification tests performed under controlled conditions, this campaign depended entirely on naturally occurring weather.
Flight test engineers, meteorologists, and pilots spent months tracking weather systems before deploying to Midland, Texas, when forecasts indicated suitable crosswind conditions.
According to Aerospace Global News, Boeing’s flight test crews remained on continuous “wind watch” for weeks, ready to travel within days whenever weather forecasts suggested the required conditions for certification testing.
Boeing Relied on Nature for Certification Flights
Because strong crosswinds cannot be created on demand, Boeing relied on carefully monitored weather patterns to complete the campaign.
Lauren Auerbach, a Boeing flight test engineer, explained that reliable weather forecast accuracy typically becomes available only 2 or 3 days before suitable conditions develop.
As a result, the entire flight test team remained prepared to launch on short notice whenever forecasts showed the required crosswinds.
This approach allowed Boeing to evaluate the aircraft in real-world weather conditions rather than simulated environments, providing valuable certification data under operationally representative conditions.
Autoland System Demonstrated
The primary objective of the campaign was to verify that the Boeing 737-10’s autoland system could safely guide the aircraft from approach to touchdown during demanding crosswind operations.
Engineers evaluated whether the automated landing system made appropriate and timely corrections to the aircraft’s flight path while keeping the aircraft within the lateral confines of the runway throughout the landing sequence.
Autoland is designed to automatically control the aircraft during the final stages of landing, reducing pilot workload while maintaining precise runway alignment when operating within certified limits.
Boeing Conducted Flights Beyond Requirements
During the certification campaign, engineers closely monitored how the autoland system responded to rapidly changing wind speeds and wind direction.
Boeing conducted many of the test flights in crosswind conditions that exceeded the minimum certification requirements.
The company focused particularly on gusting winds because they continuously change in strength and direction, creating a more demanding environment than steady winds.
Although the 737-10 is significantly longer than the other members of the 737 MAX family, Boeing stated that its autoland software has been tuned to deliver handling characteristics consistent with the 737-8 and 737-9.
This consistency helps airlines operate different MAX variants with similar aircraft behavior during automatic landings.
Why Crosswind Certification Matters
Crosswind certification is a critical requirement before an aircraft enters commercial service because it establishes the maximum wind conditions under which airlines can safely dispatch the aircraft while relying on its certified autoland capability.
Successfully demonstrating performance in demanding crosswind conditions gives regulators and airline operators confidence that the aircraft can safely conduct automatic landings during adverse weather at airports around the world.
The crosswind campaign represents one element of Boeing’s broader certification effort for the 737-10.
Earlier this year, Boeing completed maximum brake energy testing by accelerating a fully loaded 737-10 to more than 200 mph before performing a rejected takeoff using heavily worn brakes without thrust reversers.
The manufacturer also strengthened the aircraft’s landing gear and introduced the highest-capacity brakes ever installed on a 737 to support the aircraft’s increased maximum takeoff weight.
Together, these certification exercises demonstrate that the aircraft can safely operate across a wide range of challenging conditions that airlines may encounter during normal service.
Boeing Continues Toward FAA Approval
The Boeing 737-10 is the largest member of the 737 MAX family and can accommodate up to 230 passengers. The aircraft is designed to deliver the lowest seat-mile costs in the 737 MAX lineup.
Certification of both the 737-10 and the smaller 737-7 has been delayed for several years as Boeing addressed regulatory changes introduced after the 2 fatal 737 MAX accidents and implemented additional safety improvements throughout the program.
The results from the latest crosswind certification campaign will support Boeing’s remaining work with the FAA as the company continues toward certification of both aircraft later in 2026.
