We have switched to using OPT for performance and you can display a nice little diagram showing AEO, OEI and V1 stop distances along with TORA, TODA and ASDA so you can immediately see your margins and which technique would be appropriate in the circumstances. A rolling takeoff is SOP for us but if I’m going out of a balanced field with a 90deg turn on then I’ll look to minimise the runway used in the line up.
