Rffs response
Regarding the heathrow airbus incident on Friday , the Rffs resources would have been exhausted very quickly with crews dealing not only with a full evacuation , but also because of the possible engine fire and also the problems surrounding returning a/c which are generally overweight landings which can cause hot brakes on landing . From experience of the full evacuation of a virgin a340 at gatwick last year the minimum requirement of firefighters at the bottom of each chute is a minimum of 1 with a preference for 2 when dealing with multiple pax exiting under emergency evac conditions
