Good morning all,
I was reading a TSB Canada report today on a Canadian Airlines DC10-30 that overran the runway during an RTO after a loss of power on No 1 engine at Vancouver in 1995.
Interestingly in discussion on weight and balance the report notes that after the incident, when everything was weighed there were three discrepancies as follows:
23 additional passenger bags
1 additional passenger
Ramp fuel weight on documentation was lower than actual fuel weight on board.
Weight was also affected by the fact that the taxi time was half that which was planned.
This added up to an assessment that the aircraft lined up around 3000lbs over the max design take off weight for that type (590,000lbs).
My question is, assuming that the engine failure and RTO hadn’t occurred, what would have happened if the takeoff attempt was continued overweight in both the standard and engine out scenarios? Is there an allowable exceedence? I guess 3000lbs isn’t that much for this type in terms of performance, but what about structurally?
Should also add that high power ( called C2B apparently) was being used for takeoff and No2 thrust reverser was locked out.
Cheers,
GB
