slip of the old brain cell 212 (not another one!) It was 0600 in the morning when I read your thread - that's my only excuse...... and then Jim piped up in the meantime and as usual straightened things out.
Alls well that ends well but that still leaves me struggling to come up with a formula for minimum performance at the platform helideck. Is HOGE going to cut it or do I factor it by 2.5% or 5% as some have recommended. Is there any science behind this???
