Stby-Instruments?
Not knowing anyting about the A310, I find it hard to imagine that this airplane would be without any kind of nav. and comm. equipment on a separate set of batteries (be it a basic ADI and/or RMI with a VOR/LOC and GS receiver + ADF on their stby-instruments) in case of a major electrical malfunction. Doesn't the A310 have a RAT, by the way?
If they indeed had such instruments available, then there shouldn't be much praise about their 'heroic' deeds.
Because, finding their way to an adequate airport with such reduced or basic equipment may not have been easy, but definitely possible. This should have been exactly, what they've been trained for. Hopefully, that is.
