Mechanical back up
Hello,
Does anyone know for sure if during the flight test campaign for the A320 the test pilots landed the aircraft in mechanical back up.
I have heard rumour to this effect but was wondering if anyone knew for sure that this was performed.
Thank you

I don't think failure of all computers together has ever happened. Mechanical backup is after that. Safety first surely would have had an article in some issue. Like UAR or Hudson surely would have kicked up a storm.
I thought the 320 only had mechanical backup on the THS and rudder?

All modern wide bodied Airbus aircraft have "electric rudders". I understand the A320 has joined them, but it wasn't always so.
Sim fidelity suggests, and understandably so, no crosswind landings may apply here.
Mechanical backup is not easy but manageable.

Quite true across not just the Airbus fleet, but on all 100+ seat transport category aircraft - unless we include the Mad Dog, whose designers seemingly from another era, eschewed total reliance on hydraulics as well as any electrickery betwixt the cockpit and primary flight control surfaces.

I fly an M.D. with hydraulic flight controls, electronic primary and mechanical reversion, based on at least one hydraulic system functioning, otherwise back to engine asymmetry only.
I do have 4 separate hyd systems however....
Unfortunately, no pitch power couple in reversionary.....
Basic Electronic rudder, no turn cord or engine out compensation airbourne, but she does the job.
