gear down
somewhile ago i watched a britannia b757 take off from 09 at brs,his landing gear stayed down 4 a lot longer than normal.found out it was a warm/hot wheel and the crew elected too carry on and cool the wheels off in the air,what would happen if the gear failed too retract on command?is there a manual override and would the fuel consumption go up rapidly.would this be declared as a major emergency?many thanks in anticipation
