God almighty here we go again.BORING,BORING,BORING
Grange, the crew worked out the RTOW figures well before they arrived at the holding point. As you would well know?????????
Most times we are cleared for t/o without too much hassle. If there are a/c on final and nothing much to be gained the crew might request the full length on approaching delta. The figures GUARANTEE we will stop before the end of the runway if rejecting prior to V1. So there is NO intellectual (or otherwise) case for not performing intersection departures. All performance figures are as I say GUARANTEED.
There may be any number of reasons why a crew may decide not to use an intersection departure. It's up to the individual Capt in addition to a discussion with the f/o. So grange why the interest?
