dangerousmeta!, the original new mexican miscellany, offering eclectic linkage since 1999.

Register.UK: F-35s failed ‘scramble test’ because of buggy software.

During the first 30 flights with Block 3iR6.21, which accumulated 75.6 hours of flight time, no less than 27 power cycles were required to get all systems functioning between initial startup and takeoff. These power cycles varied in degree – from “cold iron” resets, where the aircraft had to be shut down and then restarted, to component or battery power recycling.” This is simply ridiculous.

Just growing pains

I should elaborate

As part of larger effort to speed acquisition, systems are being taken farther, faster without necessarily getting to “perfect” in the previous stage.

So much of test is now inclusive of continuing iterations of previous development as long as Safety of Flight is not compromised.

In some cases crappy headlines are being used to drive problem resolution IMHO, as cross-domain problems are crossing company lines and in some cases, the last poor bastard to complete test gets all the mitigation changes as software test is so expensive you avoid retroactive changes.

All speculation, I have no more insight to the program than headlines like anyone else.

“Growing pains.” It was declared ‘ready for deployment’ in July of last year. Growing pains, for an adult?

Just axin’ ...

What can I say, system complexity is going up akin to Moore’s law and Integration is largely linear.

But like many other software developments, sometimes you have to get it on the street to keep the Program healthy enough to fix it.

Luddite. Give me hydraulics over electronics.

Guy who drove last gen aircraft (even F-18) are blown away by the capability, but that brings escalating complexity.

Suggest deployment to Arctic and Antarctic; seems to be a polarizing program…
