Trim would never be a separate airfoil because that would be horrendous for efficiency. Instead they have an all-moving tailplane.
They could have prevented this issue by slightly increasing the tailplane size to restore stability margin, but they didn't presumably for development cost and fuel efficiency reasons.
- baybal2 8y agoAre you really sure that it will be "horrendous?" That thinking remind me of people who try to economise on few microns of plastic we see in electronics OEM industry. Pro managers trying to shave microns from casing, ending up with multimillion dollar recalls, and that for savings not even amounting to few snickers bars.
- CydeWeys 8y agoYou're adding an entire new system. That's more wiring, more programming, more hydraulics, more moving parts, etc. It's far from trivial.
- baybal2 8y agoFar from trivial, but it was done in the past nevertheless. All things above were going away one after another, and replaced with often ineffectual electronic safeguards.
