A
recent thread asked whether a pilot with a comms failure during the approach should have landed. The discussion showed a range of opinions and I offered some thoughts from the ATC perspective....but it got me thinking about comms failure more generally.
I'd be interested in what criteria a crew use to decide that they have a comms failure and, apart from following the appropriate RCF procedure, what actions might be taken. I'd be particuarly interested in when and by how much these criteria might change when there is relatively little time to make the determination that there is a comms failure (as was the case on approach mentioned in the other thread or, perhaps, if the aircraft has been stopped off at a nominally terrain unsafe level during the climb or maybe on base leg in a busy TMA environment).
