The Anonymous Widower

737 MAX, Airbus And Aventra

I think that there are parallels between these plains and trains.

The 737 MAX is a conventional fifty-year-old design of aircraft, that has been updated with modern technology through the years.

When Airbus designed their fly-by-wire systems about thirty years ago, they were duplicated with two independent systems, programmed by separate teams. I think that the plane could fly on one system, if the other failed. Ittook time to develop, but no-one questions its reliability today.

The design and some of the things it gets up to, like moving fuel around to balance the aircraft help to increase the efficiency of the aircraft.

Efficiency and low pilot workloads help to sell aircraft.

Boeing is now trying desperately to catch up, but doing this in an ageing design appears to be difficult.

One thing I wonder is that is misloading of cargo a problem in the two 737 MAX crashes.

Supposing there was an imbalance of cargo on an Airbus! Would the plane’s computer realise this and move fuel to conpensate? Boeing must rely on a conventional approach using the flying controls.

Boeing are obviously worried as they have installed a special anti-stall conputer system called MCAS.

So what has this got to do with Bombardier’s Aventra train, that is suffering from software problems causing delays.

The Aventra is a radical design, that rewrites the rules, just like Airbus did. It relies heavily on a sophisticated computer system to control everything and bring a higher level of efficiency.

It will take time to get right, but just as Airbus did all those years ago, I believe they will.

The Aventra will change train design by as much as Airbus have changed airliner design.

Have Boeing Gone As Far As They Can With The 737?

As a Control Engineer, who has spent a working life, solving mathematical problems, I am tending to think that in trying to stretch a fifty-year-old conventional design to match an all-composite one from Airbus, where fuel is noved around to balance the aircraft, Boeing have reached the end of the road and need a new aircraft.

They realised this with larger aircraft and produced the Dreamliner, which has been successful.
