OMG. Runway inspections aren’t carried out continuously so in conditions such as these a professional crew would factor into their take off performance calculation the possiblity of a degradation in runway state since the last inspection. That would probably entail selecting contaminated runway state, icing conditions etc in the EFB (take off performance computer). I’d do the same for SEN in similar conditions and if the EFB result was “can’t be done” I’d head back to the crew room for a coffee!
