The Anonymous Widower

My Latest Thoughts On The Boeing 737 MAX

I had this message read out on BBC’s Wake Up To Money this morning.

I have been involved in the programming of several first-of-their-kind computer systems dating back to 1969. They are always late ad usually need a couple of goes to get it right! Boeing didn’t do enough testing.

Although, I’ve been mainly involved in programming user systems and I’ve never controlled anything  by a computer program, I have worked with a lot of people who have. One team, I worked alongside, programmed the world’s first computer to fully control a large chemical plant.

But even, when I was writing something as big and complicated as Artemis, you had to take into account, that not everybody using the system, thought the way you did.

Those that fly aircraft differ in one area, that has nothing to do with sex, racial type or religion. Their experience of flying aircraft varies from a couple of thousand hours upwards.

It is no surprise to me, that some of the great aircraft stories of safe landings in difficult circumstances have been done by very experiences pilots, often with years of flying less reliable military aircraft.

They have used their experience to get themselves and their passengers out of trouble

It should be noted that the pilots of both the Indonesian and the Ethiopian planes, had several thousands hours of experience.

  • On the whole, human beings are generally risk averse and pilots are no different to the rest of us.
  • We also don’t like surprises.

How many times have you installed a new copy of a popular software system to find that it is radically different and it takes you several weeks to get used to it?

When I was writing Artemis, I made sure, that, I didn’t create any surprises for customers all over the world. The software was also tested to destruction.

Getting a calculation wrong in Artemis, would be unlikely to have had fatal consequences.

Conclusion

Have Boeing with their MCAS computer software fix to cure the inadequacies of an obsolete air frame, made two big mistakes?

  • They have created an airliner, that goes against pilot experience?
  • They didn’t do enough testing.

I will not fly in any 737 until the day I die!

  1. I have worked on 737’s. Boeing engineers make committee decisions, they do not criticise their peers mistakes, they cover up. Their culture is not risk adverse. The plane is impossible to fly normally by anyone other than a fighter pilot due to unstable airflow characteristics. The software fix relies on two sensor inputs, only one sensor was fitted. The computer was programmed to search for two inputs, and failed when one was found. It was a nightmare waiting to happen. Boeing should hold their hand up and say sorry. Pilots are not bus drivers, nor robots. Is there any hope with autonomous cars after this autonomous aeroplane experiment?

    • Thanks for that! Both flying and driving automatically must cater for every event no matter how unlikely! Am I right in thinking that switching MCAS off and flying manually was difficult?
