Aerospace stock Boeing (BA) has been working to certify the 777X for some time now, and it turns out that the certification process involves a lot more than some might expect. In fact, one of the certification methods involves what is known as “brake energy testing,” in which brakes can reach a temperature of up to 2,500 degrees Fahrenheit. This revelation did little for shareholders, though, and Boeing shares dipped fractionally in Friday afternoon’s trading.Meet Samuel – Your Personal Investing ProphetStart a conversation with TipRanks’ trusted, data-backed investment intelligence

Most of what we hear about the 777X program includes some comparatively simple, or even new, things. The folding wingtips have received their share of coverage, production issues, and even setbacks in the certification process. But that process takes a lot to accomplish, including one test that represents one of the biggest and most daunting prospects of all, an examination of the brakes.
Brake testing on the 777X certification project, reports note, is done in such a way that the brakes get extremely hot. They reach the 2,500 degrees Fahrenheit level noted earlier. And these are not fresh brakes, either, but rather brakes that have been worn down to levels approaching operational limits. The aircraft reaches 190 knots, loaded to its maximum takeoff weight, and then simulates an aborted takeoff by stopping, with no help from reverse thrust.
