back to article Flying blind: F-35's radar software fails in the air

The F-35 Joint Strike Fighter has run into yet another software bug, according to a report in IHS Jane's Defense Weekly. The glitch is in the software that operates the fighter's radar. During flight, Jane's reckons, the radar software becomes unstable. The report quotes US Air Force Major General Jeffrey Harrigian as saying …

    All that formal process (DO-178,etc.), but still a serious bug slips thru...

    And now, because of all that, it takes over a month to issue a patch.

    How about this?

    SW QA: "You must follow the process before issuing the fix."

    SW Lead: "Your process failed. It's been suspended for two months."

      Re: All that formal process (DO-178,etc.), but still a serious bug slips thru...

      You forgot the last line :

      FAA/EASA/... : "Certification denied."

      I guess you misunderstand the aim of the DO-178B/C process. It only ensure that the software is fully compliant with its specification.

      This lead to one very annoying side effects : if a given case is not specified, then it won't be tested, mostly because there's no expected behaviour to check.

      Just for the sake of the argument, what kind of process would you recommand?

        I suppose "Doesn't crash in mid-air" wasn't considered a possible use case.

          Re: All that formal process (DO-178,etc.), but still a serious bug slips thru...

          Would be rejected as "not testable". This is too broad of a requirement...

          "Any unexpected interruption shall be caught and logged in BITE if possible. Once the default is logged, the system shall be restarted." would be testable and cover a lot of cases.

          Can't remember the last time I've seen such a requirement, unfortunately...

          Also cause a Foreign Object Damage hazard

          I flew F-4 Phantoms for 8 years, before working as a software engineer for Lockheed Martin. I can just see the pilot going to zero gee for a quick roll, and then the paperclip floats out of her pocket. (I suppose that I must assume a female pilot, plus it is fun to blame them). Then the paper clip causes an electronic short circuit, or a plastic paper clip jams your ejection mechanism. That used to happen all the time with pencils.

            In that case, you have run out of options to restart the radar. If there is a bible on board specifically for this kind of oopsies or the pilot happens to have some prayer written down, that would be the right moment to put it in use.

    What a waste

    EMI, bugs, security, and who knows what else and they haven't tested a a single bit against any of them. Plus, it's a POS airplane that isn't doing what Lockheed promised. Why three versions instead of just one was also idiotic.

      Re: What a waste

      The the three versions are one for the Air Force (super sonic/stealth capabilities), one for the Navy (they have to be able to perform carrier landings, enforced landing gear and airframe), one for the Marines (to give it S/VTOL capabilities, they are mightily angry about being forced to give up their Harriers).. All in all, the plane is a dud. It's already cost a trillion and change just to get to where they are now, with more good money to be chased after bad. Time to scrap the project, sue the company that sold the US this bill of goods, look into better more inexpensive and more agile airframe that could be brought up to production in a year. From drawboard to production in a year. Add the bells and whistles when it's in the air.

        Why sue Lockheed? They are merely trying to meet the specification of pleasing all of the people all of the time. With a very, very few exceptions, multi-role combat aircraft have never realised their potential, but despite the long history of expensive failure the US DOD thought they'd have another go.

        You can certainly build better, simpler, cheaper, airworthy role-specific airframes, But in a year? Ignoring the multi-nation and multi-role fiascos, the excellent Rafale and Gripen fighters still took about twenty years or so from inception to full service.

    Failure is not an option

    It doesn't matter how many cock-ups, overruns, over-costs, and reductions in capability a government defence contract delivers (*) it will always be heralded as a great success and the future of warfare.

    The politicians, senior defence department/ministry civil servants and military personnel who are involved in the commission have too much to lose to do anything else. First they would lose face and second they would lose some of their kick-backs, sorry, non-exec directorships, fact-finding trips, etc.

    ...it's just a level of stealth that means the plane can't be tracked by looking for its own RADAR emissions.

      Re: Given that all the best and brightest minds in IT are working on this

      I doubt that the best and brightest are working on this. Even if they wanted to work for a large, bureaucratic organisation rather than a silicon valley start-up they'd still have to pass security vetting.

        Re: Given that all the best and brightest minds in IT are working on this

        Spot on. The best and brightest does not usually works in critical embedded system.

        The issue is not really on the security vetting however...

        Industry is far from being as sexy and interesting as Google's pet projects, and does not pay as well as the banking and financial sectors.

    As I have said from the very beginning, the F-35 is a gold-plated piece of dog crap. The only thing Lockheed-Martin has successfully produced is the most masterful marketing program in military history. They could sell ice cubes to Eskimos--except the cubes would melt before being delivered "because of a deficiency in the water component and the interface between hydrogen and oxygen, which will be corrected with the next software release, sometime next year... or the year after."

      and the pilot gets in mid flight a message from Microsoft Technical Support telling him (or her) that his "PC" is infected.

      Perhaps the best way to end this 'scourge' of the PC industry would be for the pilot to request landing co-ordinates so the "Technical Support" personnel can """inspect""" the problem first hand.

      The only problem the pilot would have is in explaining why he (or she) is short a missile or two upon return to base.

    While remaining quite critical to the F35*, it should be noted that not everyone is unhappy with the machine:
