Performance
I am not in a position to comment the accident as I have no relevant information on payload, fuel load,CG or the route. However here is some info that might give an insight to those that do not do RWY performance calculations daily (Ie do not fly for living).
This is an extract from CDG RWY 09L based of B747-200 with RB211-D4X engines and a F20 take off. Field elevation is 390ft some 90ft below that of Halifax with similar RWY slope of +0.15 degrees. MTOW is in this case field lenght limited
Using Halifax weather at the time of the accident:
CYHZ 140800Z 25005KT 15SM OVC016 10/09 A2968 RMK SC8 SLP054
In the CDG example limiting MTOW is 351.4 tons.
Based on that
Flight from Halifax to Zaragoza using optimum random track (Great circle) zero wins and ISA conditions, would have been approximately 5h 30 minutes. Required trip fuel in the range of 65 tons, excluding all alternate, reserve, holding fuel, tankering and crew additions.
OEW: n/a
MZFW: n/a
MTOW: n/a
Payload: n/a
Reserves: n/a
Also note that MK aircraft was equipped with P&W JT9D-7Q engines and the above scenario was based on the more powerful R&R engines.
