Which would have caused the utterance of a singularly appropriate expletive considering the ICAO code of the aerodrome in question.....
In HMFC's VC10s, we used either aerodrome-specific regulated take-off graphs, or 'general' balanced field graphs if RTOGs weren't available. For normal conditions a mid-range V1 was used; this varied for contaminated ops or for wet RWs.
Reduced thrust ('factored power') take-offs were OK using most general balanced field graphs; however, on some RWs it was necessary to use max chat - and to treat the locals to the 'silent and serene' sound of the mighty Vickers Whisperjet!
