I wonder when, if ever, sites that purport to have some aviation knowledge will actually work out that there probably isn't any such thing as an hydraulics warning light. ECAM and EICAS have only been around for 30 or so years.
I know that someone will tell me that I'm 'Mr Sympathy', but terrified by an evacuation at the gate? How would she have fared in so many of the other events that are discussed here?
Some of the claims that I've read don't match up with the data I can see on FR24. The landing does not look unusual. I can't tell whether it was towed to the gate or not, but that would be normal with some hydraulic issues (but not all).
An evacuation at the gate is an interesting event. The doors are disarmed, and so have to be armed again for the slides to operate. It's a toss up as to whether you'd be better off using the bridge or the slides. My preference was always to use the bridges if they were attached. I'm curious as to why all of the slides have not been fired. There was a procedure that allowed this, but it was removed a few years ago.
