Fireflybob's post [#4] is spot on.
If I had an aircraft with a few, or mulitple faults that, however unconnected they may seem, I feel could possibly cause a problem in the air, then I wouldn't take it. It's my neck up there aswell as the crew's, pax etc.
And I'm very glad to say I know I would get backed up by my management aswell without a shadow of a doubt.
Especially so as it's an Airbus. Well done Valerie!
